Galaxy S20 keeps lagging after Android 11 update? Here’s the fix!

In this troubleshooting guide, we will show you what to do if your Galaxy S20 keeps lagging. We will try to consider all possibilities and rule them out one after another until we can figure out the reason why the device lags and fix it for good. Read on to learn more. 

Performance issues are not really that serious. In fact, you may be able to fix them by doing one or a couple of procedures. If you’re one of the users who have encountered such a problem after the update, then here’s what you should do: 

First solution: Close background apps

Perhaps the reason why your phone keeps lagging is because there are already a lot of apps running in the background. Game apps are among the ones that will affect your phone’s performance if left running and using your device’s RAM and CPU. So the first thing you should do is close them and see if that fixes the problem. Here’s how: 

  1. Tap the Recent Apps key to view apps running in the background. 
  2. Swipe up on each app to close them, or you can simply tap Close all to quit them all at once. 

After closing the background apps, move on to the next solution. 

Second solution: Force restart your phone

While the first solution might help your phone run a little smoother, it’s better to also refresh your phone’s memory by doing the forced restart. It is a simulated battery pull procedure that has been proven to be very effective. It will also reload all core services. Here’s how you do it: 

  1. Press and hold the Volume Down button and the Power key for 10 seconds. This will force your device to shut down and power back up. 
  2. When the logo shows, release both keys and wait until the reboot is finished. 

Once the restart is complete, observe your phone closely to see if the lags are gone. 

Third solution: Wipe the cache partition

If the system cache is corrupted, that is also one of the reasons why a premium smartphone like the Galaxy S20 starts to lag. So the next thing you have to do is wipe the cache partition so the system cache will be replaced. Here’s how: 

  1. Turn off your phone completely. 
  2. If you’ve updated your phone to Android 11, connect the headset. 
  3. Now press and hold the Volume Up button and the power key. 
  4. Once the logo shows, release both keys and wait until your phone enters the recovery mode. 
  5. Now use the Volume Down button to highlight the ‘Wipe cache partition’ option, and then press the Power key to select it. 
  6. Highlight ‘Yes’ and then press the Power key. 
  7. Wiping the cache partition is pretty quick, so once it’s finished select Reboot system now to restart your device. 

Once the phone is finished rebooting, try to see if your phone is still lagging. If it does, try the next solution. 

Fourth solution: Reset all the settings on your phone

Another possibility is that the problem can be due to some settings. You may have changed something that caused the phone to lag. So to rule it out, you have to reset all the settings on your device. It’s effective but none of your files or data will be deleted. Here’s how it’s done: 

  1. Swipe down from the top of the screen and then tap the Settings icon.
  2. Find and tap General management. 
  3. Touch Reset. 
  4. Tap Reset settings. 
  5. Tap the Reset settings button. 
  6. If prompted, enter your PIN, Password or Pattern. 
  7. Tap Reset.

Once the phone is ready, try see if it still lags or if the problem is already fixed.

Fifth solution: Factory reset your phone

If the previous solutions haven’t fixed the problem, then it’s time to reset your phone. Firmware-related issues can always be fixed with a reset. However, you will have to create a backup of your important files and data as they will be deleted. When ready, follow either of the guides below so you’ll be guided accordingly: 

  1. Swipe down from the top of the screen and then tap the Settings icon. 
  2. Find and tap General management. 
  3. Touch Reset. 
  4. Tap Factory data reset. 
  5. Scroll down to the bottom of the screen and tap Reset.  
  6. If prompted, enter your PIN, Password or Pattern. 
  7. Tap Delete all.
  8. Now enter your password and then tap Done to finally reset your device. 

After the reset, set up your phone as a new device. The problem should be fixed now.
