Samsung Galaxy A20 keeps freezing. Here’s how to fix it.

Mid-range devices like the Samsung Galaxy A20 actually have really good hardware specs. You can always expect them to be stable and run fast. However, some owners seem to be experiencing performance issues with it after just a few weeks of use. The Galaxy A20 reportedly keeps freezing for no apparent reason or cause. 

We’ve been supporting Android users for almost a decade now and it’s not the first time we encountered this problem.

Basically, this problem is common but it does not necessarily mean that it’s a serious issue.

We will try to consider every possibility and rule them out one after another until we can determine the reason why such problem occurs and hopefully fix it. If you’re one of the owners of this device and are currently being bugged by a similar problem, continue reading as this post may be able to help you one way or another.

Troubleshooting Galaxy A20 that keeps freezing

Performance issues may occur from time to time and they may be due to a very minor firmware problem or glitch. In this troubleshooting guide, we will try to rule that possibility out and then move on to another solution if the other won’t work. That said, here’s what you need to do: 

First solution: Force restart your phone

This must be the first thing that you have to do, especially if the problem started without apparent reason. It is because performance-related issues are often due to minor firmware problems and if that’s the case here, then this procedure should be able to fix it. Here’s how it’s done: 

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 already rebooted, try to see if it still keeps freezing or still has some issues with its performance. If it still does, then move on to the next solution. 

Second solution: Run your phone in safe mode

By running your phone in safe mode, you’re temporarily disabling all third-party applications. It is important that you do this because there are times when apps would cause the phone to freeze or lag. Now, here’s how to restart your device in safe mode: 

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 the device is in this mode, you should still be able to use the pre-installed. Continue using your phone like you normally do and try to see if it still keeps freezing. If the problem is fixed, then it means that one or some of your downloaded apps is causing it. So, here’s what you need to do next: 

1. Restart your phone normal to boot into standard mode. 
2. Remember the apps you installed about the time when the phone started to keep freezing or lagging.
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 freezing even in safe mode, then the problem could be with the firmware. Move on to the next solution. 

Third solution: Wipe cache partition

Wiping the cache partition will delete the old system cache and replace it with a new one. You need to do this because performance issues like freezes and lags can be due to a corrupt cache. Here’s how you do it: 

1. Turn off the device.
2. Press and hold the Volume Up and Power keys.
3. When the Galaxy A20 logo shows, release all three keys.
4. Your Galaxy A20 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
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.

Once your Galaxy A20 has finished rebooting, try to see if it still keeps freezing because if it does, then move on to the next solution. 

Fourth solution: Backup your files and reset your phone

At this point, a master reset will be necessary. Performance issues can always be fixed by a reset but we often don’t suggest it without exhausting all possible solutions. But it seems like that’s the only option you have now. So, make sure to create a copy of your important files and data as you may not be able to retrieve them after the reset. After the backup, make sure to remove your Google account so that you won’t be locked out. Once everything is ready, follow these steps to reset your phone: 

1. Turn off the device.
2. Press and hold the Volume Up and Power keys.
3. When the Galaxy A20 logo shows, release all three keys.
4. Your Galaxy A20 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
6. Press Power button to select.
7. Press the Volume down key until ‘Yes’ is highlighted.
8. Press Power button to select and start the master reset.
9. When the master reset is complete, ‘Reboot system now’ is highlighted.
10. Press the Power key to restart the device.
