My Galaxy S20 Became Sluggish. Here’s The Fix!

Some owners reported that their Galaxy S20 became sluggish all of a sudden. There were those who claimed the problem started after a minor update, while others said that it just happened without apparent reason. 

Whatever the reason why your Galaxy S20 became sluggish, you just don’t have to worry so much about it because such a problem can be pretty minor. But at this point, I would like to assume that the firmware has not been compromised, or you didn’t try to modify it in any way, because if this problem due to modification, then the best thing you can do is to re-flash the stock firmware. 

If you’re one of the owners of this phone and are currently dealing with the same problem, continue reading as this article may be able to help you.

Time Needed : 20 minutes

Performance-related problems can be fixed by doing a couple of procedures, however, you must know the reason why they occur. That’s what we’re going to do here. So with that being said, here’s what you have to do:

  1. Force restart your device

    Before anything else, make sure that this issue isn’t just due to a minor firmware glitch. So the first thing that you have to do is the forced restart. It will refresh your phone’s memory and reload all apps and services. 

    1. Press and hold the volume down button and the power key for 10 seconds. This will force your phone to turn off and power back on. 
    2. Once the logo shows on the screen, release both keys and wait until the device has finished rebooting. 

    When the restart is finished, try to see if your phone is still sluggish.

  2. Reset the settings of your phone

    Another possibility is that some settings may have been messed up or some cached files may have been corrupted. So the next thing you have to do is to reset all the settings of your device. It’s basically similar to a factory reset only that none of your files 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. Finally, tap Reset. 

    After doing this and your Galaxy S20 is still sluggish, then move on to the ultimate solution.
