Fixing Galaxy S10e that’s running slow

I have encountered similar issues in the past wherein my phone starting running slow for no apparent reason at all, although I already had a hunch that it was caused by a third-party application. In this case though, let’s just be thorough in our troubleshooting. With that being said, here are the things you need to do to make your Galaxy S10e run faster again as it should:

First solution: Isolate the problem immediately

When you noticed that your phone started running slow, you must have already thought of rebooting it to fix the problem but to no avail. So, the first thing you we have to do is isolate the problem so that we would know if this is an issue caused by an application and whether or not it’s a third-party app or pre-installed. To isolate the problem, you have to restart your phone in Safe mode and here’s how it’s done.

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the screen.
  3. When SAMSUNG appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

If your phone is working normally and smoothly while in safe mode, then it means that the issue is caused by a third-party application. We don’t know which of your apps is causing it but try uninstalling the app you download about the time the problem started or the one you often use. But of course, you must make sure that your data or progress are backed up or synced with your account so that you can retrieve them once the problem is fixed.

On the other hand, if your Galaxy S10e is still running slow even in safe mode, then try doing the next solution.

Second solution: Reset all settings

Another possibility is that some settings may have been changed or messed up and most of the time we don’t know the defaults. That’s the reason why Google placed an option to make you reset all settings in your phone without deleting your files. Here’s how it’s done on your phone S10e:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset settings.
  3. Tap RESET SETTINGS.
  4. If you have set up a PIN, enter it.
  5. Tap RESET SETTINGS.
  6. The device will restart to perform the reset of settings.

After this, try to see if your phone is still running slow because if it still does, then we could say the problem is with the firmware. We have to troubleshoot the system now.

Third solution: Delete the system cache

Android creates a set of files that will help it make the phone run smoothly after the first reboot and it’s called cache. When the system cache gets corrupted or becomes obsolete, performance issues like this may occur. To rule this out, you have to wipe the cache partition so that the system cache will be deleted and replaced with a new one. Here’s how you do it:

  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 S10e logo displays, release all three keys.
  4. Once you see a black screen with blue and yellow texts, you’ve already booted the phone up in recovery mode.
  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.

It may take a little while for your phone to boot up after this but once it has become active, observe closely or use it like you normally do to know if it’s still running slow or not. If it still does, then move on to the next procedure.

Fourth solution: Backup your files and reset your phone

When it comes to performance issues like this, a master reset is the ultimate solution. However, we’re always hesitant to suggest this procedure without exhausting all possible solutions as you may lose some of your important files and data. However, now that you’ve already performed a few procedures to no avail, it’s time to reset your phone.

Therefore, make sure to create a backup of your important files and other data on your phone. And then remove both your Google and Samsung accounts so that you won’t be locked out of your device after the reset. After doing these, follow these steps to reset your phone:

  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 S10e logo displays, release all three keys.
  4. Once you see a black screen with blue and yellow texts, you’ve already booted the phone up in recovery mode.
  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.
