Troubleshooting a Galaxy A20 that keeps lagging

In troubleshooting a phone with this kind of problem, you have to be very thorough so as to accurately diagnose the problem and not lose some important files. That said, here’s what you should do: 

First solution: Perform the Forced Restart

If this problem happens for the first time, then it can be just a possible firmware glitch. It’s not serious and you may be able to fix it by doing the forced restart. It is a simulated battery removal that will refresh your device’s memory as well as reload its apps and services. 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 A20 logo shows on the screen.

Once your phone has become active, try to see if it still keeps lagging. If it does, then move on to the next solution.

Second solution: Try to find out if it’s caused by a third party app

Some apps, especially games, can make your phone stutter or lag every now and then. You need to rule this possibility out before moving on to another procedures because if it’s really the cause, then the problem is a lot easier to fix. Try to run your phone in safe mode first: 

  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. 

While your Galaxy A20 is in this mode, observe closely to see if it still keeps lagging. If the problem is fixed, then you have to do these steps to probe further: 

  1. Restart your phone normal to boot into standard mode. 
  2. Remember the apps you installed about the time when the phone starts to lag so bad.
  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. 

On the other hand, if your phone still keeps lagging even in safe mode, then move on to the next solution.
