Hi @zimma71 I take it you have a problem with your device, it helps to be a bit more specific though. However gather it is not functioning properly possibly after an update,which device do you have?
Anyway good practice after updates to wipe the cache partition and it can help fix problems, temporary files are deleted but data is not lost.
Perform the following steps:
1. Turn off the device.
2. Press and hold the Volume Up key and then press and hold the Power key (plus Bixby Key if phone has one)
3. When the Android logo displays, release all three keys.
4. An 'Installing system update' message will show for 30 - 60 seconds before the Android system recovery menu options appear.
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.
For A series you should not need to connect to computer or attach USB-C Headphones which is necessary for the S series after powering off the Device in step 1.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
