Troubleshooting Galaxy S10 Plus that started running slow

In troubleshooting performance issues with your Galaxy S10 plus, you need to be thorough so as to know the cause. I will give you the most practical yet effective troubleshooting procedures below. Try to see what works for you…

First solution: Force Restart your Galaxy S10 Plus first

Before anything else, you must try this procedure first because there’s a possibility that this is just due to a firmware issue or even a glitch. The forced restart is actually a simulated battery removal. It will refresh your phone’s memory as well as reload all its apps and services. If it’s just a minor issue with the firmware, then this should be able to fix it. Here’s how you do it:

  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 Plus logo shows on the screen.

Once your device has rebooted successfully, try to observe it to know if it’s still running slow. If it is, then move on to the next solution.

Second solution: Run your phone in Safe Mode

Doing this will temporarily disable all third-party applications. This will immediately isolate the problem so that you would know if it’s caused by an app and whether it’s third-party or pre-installed. If for example the culprit is a third-party application, then your phone should run properly when in safe mode. That’s the reason why this step is very important. Here’s how it’s done:

  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.

Continue your observation of your phone to know if it’s still running slow even in this mode because if it is, then move on to the next procedure.

Third solution: Reset Settings of your phone

Another possibility that we have to look into is that this problem could be just due to some settings especially if you tweaked some things in your device. The thing is we often don’t know where to look that’s why there exists an option that allows users to reset all settings in their phones. That’s what we’re going to do in this step.

  1. Swipe down from the top of the screen to pull the notification panel down.
  2. Touch the Settings icon on the top-right corner of the screen.
  3. Tap General management.
  4. Touch Reset.
  5. Tap Reset settings.
  6. Tap Reset settings.
  7. Enter your PIN, password or pattern if prompted.
  8. Tap Reset to reset network settings.

After this and your phone is still running slow, then it’s time to troubleshoot the firmware itself.

Fourth solution: Delete the system cache

The next thing you have to do if your Samsung Galaxy S10 Plus is still running slow even after doing the previous procedures is to delete the system cache. The cache may get corrupted at times and while it’s not really a serious problem, it may result to a poor performance. Therefore, you have to delete it so that it will be replaced with a new one. Here’s how it’s done:

  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.

  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.
