A Samsung phone that isn’t charging properly can be incredibly frustrating. Whether it’s charging slowly, intermittently, or not at all, a dead phone renders it useless. The good news is that many charging issues are often simple to diagnose and fix at home. This guide will walk you through systematic steps to fix your Samsung phone not charging properly, covering common causes from hardware to software.

Understanding Charging Problems

Before diving into solutions, it helps to understand why your phone might be experiencing charging issues. Common culprits include:

• Faulty Cables or Chargers: These are the most frequent offenders.
• Dirty or Damaged Charging Port: Lint, dust, or physical damage can prevent proper connection.
• Software Glitches: Temporary bugs in the phone’s operating system can interfere with charging.
• Battery Issues: Over time, phone batteries degrade.
• Hardware Malfunction: Less common, but internal component failures can occur.
• Environmental Factors: Extreme temperatures can affect charging.

Step-by-Step Troubleshooting to Fix Charging Issues

Start with the simplest solutions and work your way through the more complex ones.

1. Inspect and Test Your Charging Equipment (Cables & Chargers)

This is the most common cause of charging problems.

1. Check the USB Cable:
   • Visual Inspection: Look for any frays, bends, or damage to the cable itself or the connectors on either end. A kinked or damaged cable is a frequent failure point.
   • Test with Another Device: Try using your current cable to charge another compatible device (e.g., another phone, a tablet). If it doesn’t work there either, the cable is likely faulty.
   • Try a Different Cable: Use a brand new, known good quality USB cable (preferably the original Samsung cable that came with your phone or a certified replacement). This is crucial. Many cheap cables can’t handle fast charging or become unreliable quickly.
2. Check the Wall Adapter/Power Brick:
   • Visual Inspection: Look for any cracks, burn marks, or loose parts on the adapter.
   • Test with Another Device: Connect a different, known good cable to your current wall adapter and try charging another device. If it fails, the adapter is likely the problem.
   • Try a Different Adapter: Use a different, known good wall adapter (again, preferably the original Samsung one or a compatible fast charger). Ensure it provides the correct voltage and amperage for your phone.
3. Check the Power Source:
   • Try a Different Wall Outlet: Plug your charger into a different working wall outlet.
   • Avoid USB Ports on PCs/Laptops: While they can charge, PC USB ports often provide insufficient power for reliable or fast charging, especially for high-capacity phone batteries. Wall outlets are always preferred.

2. Inspect and Clean Your Phone’s Charging Port

The charging port (usually USB-C or micro-USB) can easily accumulate lint, dust, and debris.

1. Visual Inspection: Use a flashlight to carefully inspect the charging port on your phone. Look for lint, dust bunnies, pocket fluff, or any foreign objects lodged inside.
2. Gentle Cleaning:
   • Power off your phone completely.
   • Use a non-metallic, non-conductive object like a wooden toothpick, a plastic dental pick, or the tip of a cotton swab (ensure no cotton strands are left behind) to gently scrape out any debris. Be extremely careful not to damage the delicate pins inside the port.
   • Alternatively, use a can of compressed air to blow out debris. Hold the can upright to prevent propellant from spraying.
3. Test Again: After cleaning, try plugging in your charger firmly. Does it click in place securely now?

3. Restart Your Phone (Software Glitch)

Sometimes, a simple software glitch can prevent proper charging.

1. Perform a Soft Reset:
   • Press and hold the Power button for about 10-15 seconds.
   • Tap Restart when the option appears.
   • If your phone is completely unresponsive, hold Volume Down + Power button simultaneously for about 10-15 seconds until the device restarts.
2. Test Charging: After the restart, plug in your charger and see if it charges normally.

4. Check for Software Updates

Outdated software can sometimes lead to performance issues, including charging problems.

1. Go to Settings > Software update (or System updates).
2. Tap Download and install.
3. If an update is available, download and install it. Your phone will restart.
4. After the update, try charging again.

5. Clear Cache Partition

A corrupted system cache can cause various issues, including charging problems. Wiping the cache partition won’t delete your personal data.

1. Power off your phone completely.
2. Boot into Recovery Mode:
   • For newer Samsung devices (no physical home button): Press and hold Volume Up + Power button simultaneously. Release both buttons when the Samsung logo appears.
   • For older Samsung devices (with physical home button): Press and hold Volume Up + Home Button + Power Button simultaneously. Release all buttons when the Samsung logo appears.
3. Navigate in Recovery Mode: Use the Volume Up/Down buttons to navigate.
4. Select “Wipe cache partition” (use the Power button to select).
5. Select “Yes” to confirm.
6. Once complete, select “Reboot system now.”
7. After reboot, try charging.

6. Check for “Moisture Detected” Warning

If your Samsung phone displays a “Moisture Detected” or “Moisture in charging port” warning, it will prevent charging to protect internal components.

1. Do NOT plug in the charger.
2. Allow the phone to air dry completely. This can take several hours, or even a day.
3. You can try placing the phone in a well-ventilated area, using a small fan, or putting it in a bag of rice (though this is often debated for effectiveness and potential for rice dust).
4. Once the warning disappears, try charging again.

7. Test in Safe Mode

Safe Mode starts your phone with only essential system apps, disabling all third-party apps. This helps determine if a recently installed app is interfering with charging.

1. Press and hold the Power button until the Power off menu appears.
2. Tap and hold “Power off” until the “Safe Mode” option appears.
3. Tap “Safe Mode.” Your phone will restart in Safe Mode (you’ll see “Safe mode” at the bottom of the screen).
4. In Safe Mode, try plugging in your charger.
   • If it charges properly in Safe Mode: A third-party app is likely the culprit. Restart your phone normally and start uninstalling recently installed apps one by one until the issue is resolved.
   • If it still doesn’t charge in Safe Mode: The issue is likely hardware-related or a deeper software problem.
5. To exit Safe Mode, simply restart your phone normally.

8. Consider a Factory Reset (Last Resort Software Fix)

A factory reset will erase all data on your phone and restore it to its original factory settings. This should only be done after backing up all your data and trying all other software fixes.

1. Back up all your data thoroughly.
2. Go to Settings > General management > Reset > Factory data reset.
3. Follow the on-screen prompts to confirm the reset.
4. Once the phone reboots and you set it up, try charging before installing any apps.

9. Hardware Issues & Professional Repair

If none of the above steps resolve the issue, it’s likely a hardware problem.

• Damaged Charging Port: The physical port itself might be damaged internally, requiring replacement.
• Faulty Battery: Batteries degrade over time, especially after 2-3 years. A swollen or very old battery might not hold a charge or charge properly.
• Internal Component Failure: Issues with the charging IC (integrated circuit) on the motherboard, or other internal components, can prevent charging.

What to do:

• Contact Samsung Support: If your phone is still under warranty, contact Samsung’s customer service or visit an authorized service center.
• Professional Repair Shop: If out of warranty, take your phone to a reputable phone repair shop. They can diagnose and replace faulty components.

Fixing a Samsung phone that isn’t charging properly often comes down to systematically eliminating potential causes. By starting with the simplest checks like cables and chargers and progressing through port cleaning and software troubleshooting, you can resolve many issues yourself. If all else fails, a professional diagnosis and repair will be necessary to get your device powered up again.

Over time, your Samsung Galaxy phone accumulates various app preferences, such as default apps for specific actions (e.g., opening links, viewing photos), disabled apps, notification settings, and permissions. Sometimes, these settings can become confusing or lead to unexpected behavior. If you’re experiencing issues like links not opening in the correct app, missing notifications, or simply want a fresh start with your app defaults, knowing how to reset app preferences on Samsung Galaxy can be incredibly helpful.

This process essentially reverts all your app-related settings to their default state, without deleting any of your apps or their data.

Why Reset App Preferences?

• Troubleshooting App Behavior: If an app is acting strangely, not opening files, or not receiving notifications, resetting preferences can often fix underlying conflicts.
• Fixing Default App Issues: Accidentally set the wrong app as a default for photos, videos, or web links? Resetting preferences clears these defaults, allowing you to choose again.
• Re-enabling Disabled Apps: If you disabled a system app and now need it back, this process will re-enable it.
• Granting Permissions Again: All granted app permissions will be reset, and apps will ask for them again when needed. This can be useful if you suspect a permission issue.
• Restoring Notification Settings: If you’ve tinkered with notification settings and now aren’t receiving them as expected, a reset can help.

What Happens When You Reset App Preferences?

It’s important to understand what this action does and does not do:

What it DOES:

• Resets all disabled applications.
• Resets disabled application notifications.
• Resets default applications for actions (e.g., your default browser, gallery app).
• Resets all background data restrictions for applications.
• Resets all permission restrictions for applications.

What it DOES NOT do:

• Delete any of your apps.
• Delete any app data (e.g., photos, messages, saved game progress).
• Perform a factory reset of your phone.
• Affect your personal files.

Steps to Reset App Preferences on Samsung Galaxy

The process is straightforward and typically involves navigating through your phone’s Settings menu.

1. Open Settings:
   • On your Samsung Galaxy phone, swipe down from the top of the screen to open the Quick Settings panel.
   • Tap the gear icon (Settings) in the top right corner.
2. Navigate to Apps (or Apps & notifications):
   • In the Settings menu, scroll down and tap on Apps (on some older Android versions, it might be “Apps & notifications” or “Application manager”).
3. Access More Options:
   • Once in the Apps section, look for a three-dot menu icon (usually in the top right corner) or a three-line menu icon (often on the left). Tap it to open more options.
   • Note: On some newer Samsung devices with One UI, you might need to tap “Choose default apps” first, and then look for the three dots or a reset option. However, the most common path is directly from the main Apps menu.
4. Select “Reset app preferences”:
   • From the dropdown menu that appears, tap on Reset app preferences.
   • You might be asked to confirm your choice. A pop-up will usually explain what will be reset.
5. Confirm the Reset:
   • Read the confirmation message carefully. It will reiterate what settings will be affected.
   • Tap Reset apps (or “Reset”) to proceed.

Once you confirm, the process is usually instant. You won’t see a progress bar, but the changes will be applied immediately.

What to Expect After Resetting App Preferences

After you reset app preferences:

• Default apps will be cleared: The next time you perform an action that requires a default app (like opening a web link), your phone will ask you to choose a new default.
• Disabled apps will be re-enabled: Any apps you previously disabled will reappear in your app drawer and can receive notifications again.
• Permissions will be requested again: Apps will ask for permissions (e.g., access to your camera, microphone, contacts) the next time they need them.
• Notifications will be restored: All app notification settings will revert to their factory defaults.

When to Use This Feature

• When a specific app is misbehaving and traditional troubleshooting (clearing cache/data, reinstalling) hasn’t worked.
• When you want to re-establish default apps from scratch.
• If you’ve disabled too many apps or notifications and want to bring them back to a working state.
• As a general troubleshooting step before resorting to a more drastic factory reset.

Resetting app preferences is a powerful but safe troubleshooting step for many common Android app-related issues on your Samsung Galaxy device. It offers a way to refresh your app environment without the hassle of a full factory reset and data loss.

1. Press Windows key + X.
2. Press U (for Shut down or sign out).
3. Press U again (for Shut down). This sequence is often referred to as Win + X, U, U.

Method 3: Using the Ctrl + Alt + Del Screen

The Ctrl + Alt + Del combination is an iconic keyboard shortcut in Windows, historically used for various functions, including bringing up the Task Manager and providing system security options.

Steps:

1. Access the Security Options screen:
   • Press Ctrl + Alt + Del simultaneously. This will open a full-screen menu with options like “Lock,” “Switch user,” “Sign out,” and “Task Manager.”
2. Locate the Power icon:
   • In the bottom-right corner of the screen, you will see a Power icon.
3. Select the Power icon:
   • Use the Tab key to navigate through the options on the screen until the Power icon is highlighted. (You might need to press Tab multiple times.)
4. Open the Power menu:
   • Press Enter. A small menu will pop up with “Sleep,” “Shut down,” and “Restart” options.
5. Select “Shut down”:
   • Use the Down arrow key to highlight “Shut down.”
6. Confirm the shutdown:
   • Press Enter. Your PC will shut down.

Method 4: Creating a Custom Shutdown Shortcut

For those who want a single, dedicated keyboard shortcut for shutdown, creating a desktop shortcut is an excellent option.

Steps:

1. Create a new shortcut on your desktop:
   • Press Windows key + D to go to the desktop.
   • Press Alt + Spacebar, then W (or use Shift + F10 to open the context menu).
   • Use the Down arrow key to select “New,” then press Right arrow key, and then Down arrow key to select “Shortcut.” Press Enter.
2. Enter the shutdown command:
   • In the “Type the location of the item:” field, type: shutdown.exe /s /t 0
   • Press Enter or click “Next.”
3. Name the shortcut:
   • Type a name for your shortcut, such as “Shut Down Now.”
   • Press Enter or click “Finish.”
4. Assign a keyboard shortcut to the new shortcut:
   • Highlight the newly created shortcut on your desktop.
   • Press Alt + Spacebar, then R (or use Alt + Enter for properties).
   • In the “Properties” window, go to the “Shortcut” tab.
   • Click in the “Shortcut key:” field.
   • Press your desired keyboard shortcut combination (e.g., Ctrl + Alt + S). Windows will automatically add “Ctrl + Alt” or “Ctrl + Shift” if you press only one letter. Choose a combination that won’t conflict with other applications.
   • Click OK or press Enter.

Now, whenever you press your assigned keyboard shortcut (e.g., Ctrl + Alt + S), your computer will shut down immediately without prompts (due to the /t 0 parameter, which means zero seconds delay).

Understanding the Command: shutdown.exe /s /t 0

• shutdown.exe: This is the executable program responsible for shutting down or restarting Windows.
• /s: This parameter tells the shutdown.exe command to perform a full shutdown.
• /t 0: This parameter specifies a timeout period in seconds before the shutdown occurs. Setting it to 0 means the shutdown will happen immediately. Be careful with this, as it won’t give you time to save open work. For a 30-second delay, you would use /t 30.

Method 5: Using the Run Dialog (Windows Key + R)

The Run dialog is a quick way to execute commands, including the shutdown command.

Steps:

1. Open the Run dialog:
   • Press Windows key + R.
2. Type the shutdown command:
   • In the “Open:” field, type shutdown /s /t 0 (for immediate shutdown) or shutdown /s (to get a 30-second warning and ability to cancel).
3. Execute the command:
   • Press Enter or click “OK.” Your computer will shut down according to the command you entered.

Frequently Asked Questions (FAQ)

Q1: What is the fastest keyboard shortcut to shut down Windows 10?

The fastest method for an immediate shutdown using the keyboard is to press Windows key + R, type shutdown /s /t 0, and then press Enter. Be aware that this shuts down without any prompts to save work.

Q2: My mouse isn’t working. How can I shut down my computer with the keyboard?

The most reliable method when your mouse isn’t working is to use Alt + F4 after pressing Windows key + D to ensure the desktop is active. Then, use the arrow keys to select “Shut down” and press Enter. Alternatively, Ctrl + Alt + Del, then use Tab to navigate to the Power icon, press Enter, use Down arrow to “Shut down”, and press Enter.

Q3: Is there a way to force a shutdown using the keyboard if my PC is frozen?

If your PC is completely frozen and unresponsive to the above keyboard shortcuts, your last resort (and not a recommended regular shutdown method) is a hard shutdown: press and hold the physical power button on your computer for about 5-10 seconds until it turns off. This can lead to data loss.

Q4: Can I restart my computer using a keyboard shortcut?

Yes. In the Alt + F4 shutdown dialog, use the arrow keys to select “Restart” instead of “Shut down” and press Enter. Similarly, in the Windows key + X menu (Win + X, U), you can select “Restart” instead of “Shut down”.

Q5: Will using these keyboard methods save my open work?

Most of these methods (like Alt + F4 from the desktop, Windows key + X menu, and Ctrl + Alt + Del menu) will prompt you to save any unsaved work in open applications before proceeding with the shutdown. However, using shutdown /s /t 0 in the Run dialog or a custom shortcut set to t 0 will initiate an immediate shutdown without prompting, so use those with caution.

Q6: Can I schedule a shutdown using a keyboard command?

Yes. Using the Run dialog (Windows key + R) or Command Prompt, you can type shutdown /s /t XXXX, where XXXX is the number of seconds you want to delay the shutdown. For example, shutdown /s /t 3600 would shut down your computer in one hour.

Q7: Do these methods work on Windows 11 as well?

Yes, most of these keyboard shortcuts and methods are consistent across Windows 10 and Windows 11, reflecting Microsoft’s commitment to maintaining familiar user experiences.

Setting up a wireless mouse and keyboard with your laptop can really upgrade your workspace. Whether you’re going for a cleaner desk setup, better ergonomics, or just want more freedom to move around, the process is usually quick and easy.

In this guide, we’ll walk you through the two main connection methods—via a USB receiver or Bluetooth—so you can get your gear up and running in no time.

Understanding Your Wireless Setup Options

First, figure out what kind of wireless mouse and keyboard you have. That’ll determine how you connect them.

1. USB Receiver (2.4 GHz Wireless)

• Comes with a tiny USB dongle (called a receiver) that plugs into your laptop.
• Uses a 2.4 GHz wireless signal for communication.
• Often one receiver can connect both mouse and keyboard if they’re from the same brand (e.g., Logitech Unifying Receiver).

Pros: Plug-and-play, fast and reliable connection, no need to mess with settings.
Cons: Needs a free USB port.

2. Bluetooth

• Connects directly to your laptop’s built-in Bluetooth, so no dongle required.

Pros: Leaves your USB ports free; great for minimal setups or travel.
Cons: Pairing can take a bit longer, and sometimes there’s a bit of lag or connectivity quirks.

How to Connect via USB Receiver (Most Common & Easiest)

Step 1: Get Everything Ready

1. Unpack the Devices: Take out your mouse and keyboard.
2. Insert Batteries: Most wireless devices need AA or AAA batteries (or may have built-in rechargeable ones). Check for battery compartments on the underside.
3. Find the USB Receiver:
   • Sometimes it’s hidden in the mouse or keyboard.
   • Other times, it’s in the packaging.

Step 2: Plug in the Receiver

1. Choose an open USB-A port on your laptop. (If you only have USB-C ports, you’ll need an adapter.)
2. Insert the receiver. Your laptop should recognize it right away and start installing any drivers.

Step 3: Power On and Test

1. Turn on both the mouse and keyboard (check for a power switch).
2. Try moving the mouse or typing something to make sure they’re working.

Troubleshooting Tips

• Nothing’s happening? Double-check the batteries and power switch.
• Still no luck? Try a different USB port or restart your laptop.
• Some devices have a small “Connect” button—you may need to press it to pair.
• Too much interference? Avoid blocking the receiver with metal objects or placing it too far from the devices.

How to Connect via Bluetooth (No Dongle Needed)

If your mouse and keyboard are Bluetooth-enabled, and your laptop has Bluetooth (most modern ones do), here’s how to pair them.

Step 1: Prep the Devices

1. Power them on.
2. Enter Pairing Mode:
   • Usually, there’s a small Bluetooth or “Pair” button.
   • Some require holding the power button down for a few extra seconds.
   • A blinking light usually means the device is ready to pair.

Tip: If you’re unsure how to activate pairing mode, check the user manual or manufacturer’s website.

Step 2: Enable Bluetooth on Your Laptop

On Windows:

• Go to Settings > Bluetooth & devices.
• Toggle Bluetooth to “On.”

On macOS:

• Go to System Settings > Bluetooth (or System Preferences on older versions).
• Make sure Bluetooth is turned on.

Step 3: Pair the Devices

On Windows:

1. Click Add Device > Bluetooth.
2. Select your mouse or keyboard when it appears.
3. For keyboards, you may be asked to type a code to verify the connection—just follow the prompt.

On macOS:

1. Your Mac will automatically start scanning.
2. Click Connect next to the correct device name.
3. If prompted, type a short pairing code for the keyboard.

Step 4: Test Everything

• Mouse: Move it around and check for cursor response.
• Keyboard: Open a text editor and try typing.

Bluetooth Troubleshooting

• Not seeing the device? Double-check it’s in pairing mode.
• Turn Bluetooth off/on again on your laptop.
• Make sure the device isn’t connected to something else.
• Check battery levels—low battery can prevent successful pairing.

Helpful Tips for Any Setup

• Battery Life: Keep spare batteries or charging cables nearby, especially for rechargeable devices.
• Driver Software: Some manufacturers offer apps for extra features (e.g., Logitech Options+, Razer Synapse). Worth checking out if you want more customization.
• Tiny Dongles = Easy to Lose: If your mouse or keyboard has a built-in holder for the receiver, use it when you’re on the go.
• Clean Regularly: A clean keyboard and mouse work better and last longer.

In Summary

Wireless mice and keyboards are super handy, and getting them set up—whether through a USB receiver or Bluetooth—is usually painless. Once connected, they can make a big difference in how comfortable and efficient your laptop setup feels.

While formatting a USB drive through the Windows File Explorer is easy, sometimes it just doesn’t work. You might encounter errors, see the wrong capacity, or the drive might not even show up at all. In these cases, the Command Prompt (CMD) and its powerful Diskpart utility are your best tools to force a format and restore your drive to working order.

This guide will walk you through the exact steps to format a USB drive using CMD. While the process is powerful, it is also unforgiving. One wrong command can erase data from the wrong drive. I’ve used this method many times to fix stubborn drives, and the key is to be slow, careful, and precise. Follow these steps exactly to do it safely.

The Most Important Step: Back Up Your Data!

Warning: This process will permanently erase everything on the USB drive. Before you begin, check if you can access the drive on any computer and back up any important files. Once you use the clean command, there is no going back.

When Should You Use CMD to Format?

• When the standard Windows format tool fails with an error.
• When the USB drive is showing the incorrect size or capacity.
• When the drive is corrupted and not accessible through File Explorer.
• To remove stubborn write protection that other methods can’t fix.

Step 1: Open Command Prompt as an Administrator

To use Diskpart, you need administrative privileges.

1. Click the Start Menu or press the Windows key.
2. Type cmd.
3. Right-click on Command Prompt in the search results and select Run as administrator.
4. A User Account Control window will pop up. Click Yes.

You will now be looking at a black Command Prompt window.

Step 2: Launch the Diskpart Utility

Diskpart is the command-line tool that lets you manage your computer’s drives.

• In the Command Prompt window, type the following command and press Enter:
  • diskpart
• Your prompt will change to DISKPART> to show that you are now inside the utility.

Step 3: Identify Your USB Drive

This is the most critical step of the entire process. You must correctly identify your USB drive to avoid erasing one of your computer’s main drives.

• In the DISKPART> prompt, type the following command and press Enter:
  • list disk
• A list of all the disks connected to your computer will appear. They will be labeled Disk 0, Disk 1, and so on.
• Carefully identify your USB drive by looking at the Size column. For example, if you have plugged in a 32 GB USB drive, it will show a size slightly less than that (e.g., 28 GB or 29 GB). Your computer’s main hard drive (C:) will likely be much larger and is almost always Disk 0.

In the example below, Disk 2 is a 14 GB USB drive.

Disk ###  Status         Size     Free     Dyn  Gpt

——–  ————-  ——-  ——-  —  —

Disk 0    Online          476 GB      0 B        *

Disk 1    Online          931 GB      0 B        *

Disk 2    Online           14 GB      0 B

Step 4: Select and Clean the Drive

Once you are 100% certain which disk is your USB drive, you need to select it.

• Type the following command, replacing # with the number of your USB drive, and press Enter:
  • select disk #
  • For our example, we would type select disk 2. Diskpart will confirm with the message “Disk 2 is now the selected disk.”
• Now, to erase all existing partition and volume information from the drive, type the clean command and press Enter:
  • clean Diskpart will work for a moment and then display “DiskPart succeeded in cleaning the disk.”

Step 5: Create a New Partition

With the drive now completely blank, you need to create a new partition to hold data.

• Type the following command and press Enter:
  • create partition primary Diskpart will confirm that it has succeeded in creating the specified partition.

Step 6: Format the Partition

Now it’s time to format the new partition with a file system. This is where you choose the format type.

• Type the following command and press Enter:
  • format fs=ntfs quick Let’s break this command down:
• format fs=: This is the command to format the selected partition.
• ntfs: This specifies the file system. You have three main choices:
  • NTFS: The modern, standard file system for Windows. Best for larger drives used exclusively with Windows PCs.
  • FAT32: The most compatible file system. It works with Windows, macOS, and Linux, but it cannot handle individual files larger than 4 GB. Use this for maximum compatibility.
  • exFAT: A modern replacement for FAT32 that does not have the 4 GB file size limit. It’s a great choice for cross-platform use with large files.
• quick: This performs a quick format. It’s much faster and is fine for most situations. If you omit this, Diskpart will perform a full format, which can take a very long time on large drives. Diskpart will show a percentage progress and will notify you when it has successfully formatted the volume.

Step 7: Assign a Drive Letter and Exit

Finally, you need to assign a drive letter to make the USB visible in File Explorer.

• Type the following command and press Enter:
  • assign Diskpart will automatically assign the next available drive letter (e.g., E: or F:).
• You are now finished. To exit the Diskpart utility, type exit and press Enter.
• To close the Command Prompt window, type exit again and press Enter.

Your USB drive is now freshly formatted, clean, and ready to use.

• Performance Impact: Changing fonts usually won’t affect performance, though extremely fancy fonts might use a tiny bit more resources—rarely noticeable.
• Revert Anytime: Want to go back? Just choose “Default” in the Font style menu.

Changing fonts on your Samsung phone is an easy way to freshen up your device and make it feel more personal. Whether you tweak size, try bold, or add new fonts, you’re in control of how your phone looks and feels.

When you’re baking or roasting, even a small oven temperature inaccuracy can throw things off. If your cookies are always a little too brown or your casseroles seem underdone, your Samsung oven might need calibration. Fortunately, many Samsung ovens let you make small adjustments to align the displayed temperature with the actual one. Here’s how to do it.

Why Calibrate Your Samsung Oven? Ovens can be slightly off straight from the factory or drift over time. A minor miscalibration—even just 10 or 20 degrees—can affect your food. Calibration helps you:

• Avoid undercooked or overcooked dishes.
• Bake more consistently.
• Reduce guesswork and frustration.

What You’ll Need

• Oven-safe thermometer: Don’t rely on built-in sensors. Get a quality oven thermometer you can place inside your oven.

Step 1: Check the Temperature Offset

1. Place your oven thermometer on the middle rack.
2. Set oven to 350°F and let it preheat.
3. Wait another 20-30 minutes after the oven signals it’s ready.
4. Check the thermometer reading through the window:
   • If it reads 370°F, your oven runs 20° too hot. You’ll subtract 20.
   • If it reads 330°F, it’s 20° too cold. You’ll add 20.

Step 2: Calibrate Your Oven Methods vary by model, so check your user manual. Here are two common approaches:

Method A: Digital Control Models

1. Press and hold the Settings or Clock/Setting button (usually for 3-5 seconds).
2. Navigate to Temp Adjust, CAL, or similar using arrow keys.
3. Press Start/Set to enter.
4. Adjust the temperature up or down (e.g., −20 or +20).
5. Press Start/Set again to save.
6. Press Clear/Off to exit.

Method B: Older Models (Manual Buttons)

1. Hold down a combo like Bake + 1, or Bake + Broil, until a setting like “ADJ” or “SF” appears.
2. Use arrows or number pad to adjust by increments.
3. Press Start/Set to save.

Step 3: Retest Your Oven

1. Preheat to 350°F again.
2. Wait 20-30 minutes.
3. Recheck the thermometer.
4. Fine-tune the calibration if needed.

A Few Tips

• Thermometer Accuracy: Use a trusted thermometer. If unsure, test with another.
• Fluctuations Are Normal: Oven temps naturally cycle. Look for an average, not a perfect line.
• Too Far Off?: If you’re outside the ±35°F range, there may be a hardware issue. Call Samsung support or a technician.

Don’t Skip the Manual Each Samsung oven model may differ slightly. Your user manual is your best resource for model-specific calibration steps.

Encountering a Samsung TV black screen with sound can be incredibly frustrating. You can hear the audio from your show, game, or movie, but there’s no picture to go along with it. This common issue often points to a problem with the TV’s display or the video signal. Thankfully, many causes can be fixed with some methodical troubleshooting.
