Troubleshooting Galaxy S10 Plus that’s running slow

As long as your phone doesn’t have any signs of physical or liquid damage, don’t worry too much if it started running slow as you can always fix it on your own. Most of the time, when this problem happens, it’s just due to some apps or minor firmware problems and here’s what you need to do about it…

Force restart your phone that’s running slow

If this is the first time that you noticed that your phone is running slow, then don’t do any complicated troubleshooting yet. Perhaps a forced restart may fix this issue as such is the case with similar problems we’ve encountered in the past. A forced restart can refresh your phone’s memory as reload all its services. To do it, press and hold the volume down and power keys at the same time for 10 seconds or until the logo shows on the screen.

Your phone will reboot like it normally does and once it becomes active, continue using it to know if it’s still running slow because if it still does, then move on to the next procedure.

Run your phone in safe mode to know if it’s running slow in that state

Running your phone in safe mode alone won’t fix the problem but it’s very important to do this as this will give you an idea as to what causes the problem. If the issue is caused by third-party applications, then your phone will run normally while in safe mode. So, try doing these steps first and see what happens:

  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.

Assuming that your Galaxy S10 Plus is working normally while in this mode, the next thing you have to do is find out which of your apps is causing the problem and then uninstall it. You may have to uninstall more than one app to fix this problem.

However, if the phone is still running slow while in this mode, then move on to the next solution.

Reset all settings to fix phone that’s running slow

It is also possible that the cause of the problem are some incorrect settings. So, in this step, it’s better to just reset all the settings in your phone so that it will be brought back to its factory default settings or out-of-the-box configuration. Don’t worry, none of your files will be deleted if you did this. It’s safe for both your phone and files but very effective in fixing a lot of issues. Here’s how it’s done:

  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.

Continue your observation of your phone to know if it’s still running slow because if it does, then it’s time to replace the cache that the system is using.

Delete the system cache so it will be replaced

The system cache is a collection of hundreds of small files used by the system so that your phone will run smoothly and normally. When these files get corrupted, performance issues will happen and that could be the reason why your phone is now running slow even just after a few weeks of having it. To address this possibility, here’s what you need to do:

  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 Android logo displays, release all three keys.
  4. An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  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.

After doing this, continue using your phone to know if it’s still running slow and if it still does, then you need to do the ultimate solution to any performance issue.

Backup your files and perform the Master Reset

After doing the previous procedures and your Samsung Galaxy S10 Plus is still running slow, then you must reset your phone. A master reset will fix any firmware-related problems including performance issues. However, you must take a little time to backup your files and data as they will be deleted during the process and considering your phone is running slow, it might take longer than usual.

After the backup, make sure to remove your Google and Samsung accounts from your phone so that you won’t be locked out after the reset. Once your phone is set, follow these steps to master reset 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 green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.
