Fixing a Galaxy S10 that’s running slow and why this problem occurs

What we know so far is that your phone has started to become laggy or sluggish after an update but we don’t really know what caused it. Perhaps it’s just due to the update, apps or corrupt files. In this post, we will try to consider all possibilities and rule them out one by one until we can determine the reason why your phone now has a poor performance. With that being said, here are the things you need to do: 

First solution: Perform the Forced Restart on your Galaxy S10

When it comes to fixing any smartphone that started to run slow after an update, the first thing that you have to do is the Forced Restart, or simulated battery removal. It’s because there’s always a possibility that the issue you’re currently experiencing is caused by a minor issue with the firmware or even just a glitch. Such things can be fixed by the forced restart and doing so may save you from a lot of trouble. 

How to do the Forced Restart

  1. Press and hold the Volume Down button and don’t release it yet. 
  2. While holding down the volume button, press and hold the Power key as well. 
  3. Keep both keys held down together for 15 seconds or until the Galaxy S10 logo shows on the screen.

Once the device has finished restarting, continue to use it to know if the problem has remained. If your Galaxy S10 still runs very slowly, then try the next solution. 

Second solution: Restart your Galaxy S10 in Safe Mode

The purpose of this procedure is to isolate the problem. There are times when third-party applications may cause some performance-related issues that might be the case here. That’s the reason why you need to run your phone in safe mode to temporarily disable all download apps. If your S10 runs properly while in this mode, then the issue is caused by some third-party apps and that makes it a lot easier to fix. 

How to Restart your phone in Safe mode

  1. Press and hold the Power key until options show. 
  2. Tap and hold the Power off option until it changes into Safe Mode. 
  3. Tap the Safe mode icon to restart your device.
  4. Once the reboot is successful, you should see ‘Safe mode’ at the lower-left corner of the screen. 

After you’ve successfully rebooted your Galaxy S10 in safe mode, continue using it like you usually do to know if it’s still running slow. If the problem is fixed, then this is what you need to do next: 

  1. Restart your phone normal to boot into standard mode. 
  2. Remember the apps you installed about the time when the phone started to run very slowly.
  3. Once you already have an app in mind, swipe down from the top of the screen to pull the notification panel down. 
  4. Tap the Settings icon on the upper-right corner. 
  5. Scroll to and then tap Apps. 
  6. Find and tap suspected app. 
  7. Tap Storage. 
  8. Touch Clear data and tap OK to confirm.
  9. Tap the back key once and then touch Uninstall. 
  10. Confirm that you want to remove the app from your phone. 

However, if your phone is still laggy or sluggish even in safe mode, then it’s time to troubleshoot the settings and the firmware. 

Third solution: Reset all your Galaxy S10 Settings

It is also possible that some settings in your phone were messed up after the Android 10 update. Some caches may have been corrupted resulting in some settings to be unrecognizable to the system. To rule this possibility out, you need to reset all the settings on your device. 

How to reset all settings

  1. Swipe down from the top of the screen to pull the notification panel down. 
  2. Tap the Settings icon on the upper-right corner. 
  3. Scroll to and tap General management. 
  4. Touch Reset. 
  5. Tap Reset settings. 
  6. Tap the Reset settings button. 
  7. If prompted, enter your PIN, Password or Pattern. 
  8. Finally, tap Reset.

Once the settings reset is done, try to see if your phone is still running so slowly because if it does, then move to troubleshoot the firmware itself. 

Fourth solution: Try deleting the old system cache

As I mentioned in the previous procedure, it’s possible that some caches may have been corrupted and aside from messing up the settings, a corrupt cache will always cause performance-related problems. That might be the case here and so the next thing that you have to do is to delete the old cache so that it will be replaced with a new one. You can do so by wiping the cache partition. 

How to wipe cache partition

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy S10 logo shows, release all three keys.
  4. Your Galaxy S10 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.
  9. Press the Power key to restart the device.

When the restart is finished and your phone is still very slow, then move on to the next solution. 

Fifth solution: Master Reset your Galaxy S10

The fact is a reset will always fix any performance issues provided that the firmware has not been modified in any way or that your phone doesn’t have any signs of physical damage. If all else fails, then you have no other choice but to do it. However, before you do that, make sure to create a copy of your important files, especially the ones that are saved in your phone’s internal storage. Also, it’s better to remove the google account you’ve set up on your phone so that you won’t be locked out and that you can always use a different account after the reset. When you’re ready, follow the instructions below to reset your phone. 

How to do the master reset

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy S10 logo shows, release all three keys.
  4. Your Galaxy S10 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

After the reset, set up your phone as a new device. I hope that we’ve been able to help you fix your Galaxy S10 that started running slow after the Android 10 update. Thanks for reading!
