Safe Mode lets you boot the Android system on your Samsung Galaxy S8 without launching third-party apps and applications. The mode is usually terminated by restarting the smartphone.
Now it can be, however, that the safe mode on your Samsung Galaxy S8 can no longer be terminated.
The reason for this is relatively simple. Safe mode is activated by pressing the volume key. If this is now clamped by your case or protective sheath, then this is pressed permanently. This is, of course, also the case with every restart, which means that the Safe Mode is booted.
Therefore, please remove your protective cover once, in order to free a clamped volume button.
In the worst case, the volume key can also be permanently broken. Then we recommend you to give the Samsung Galaxy S8 in the repair.
