Samsung Galaxy S21 FE 5G

When using the Samsung Galaxy S21 FE 5G, the smartphone may crash, freeze, randomly restart and/or slow down.

1. The first step we recommend is to turn off your Samsung Galaxy S21 FE 5G.

The default way to do so is to press and hold the volume down key and side key at the same time.

If done correctly, you should bring up the Power menu, where you then need to select the “Power off” option.

2. Next, you should turn back on your phone and then use the optimize now feature.

To do so, open the Settings app from the home screen of your Galaxy S21 FE 5G and then select Battery and device care > Optimize now.

Therefore, we recommend only keeping only a few applications opened at the same time.

6. Furthermore, we recommended that you uninstall any apps that you don’t use often.

7. If the internal storage of the Samsung Galaxy S21 FE 5G gets too full, then it may lead to performance problems.

To delete files, open the Settings app and then tap Battery and Device Care > Storage.

8. You should also try updating the apps that are still installed on your Samsung Galaxy S21 FE 5G as the new software versions may help fix the crashing, freezing, random restarting and slowdown issues.
