Random loss of data

[Billc1]

I have the Galaxy A42 5G which I Have had for around 14 months without any problems but for the last two months it randomly seems to uninstall apps, delete contacts, delete all text messages and change the sound setting to mute I have done a full factory reset on the phone hoping this would sort it but the problem is still apparent. Has anyone else had this same problem if so can you help please a quick response would be appreciated. I am getting to the point where I am thinking about just dumping the phone.

Try using the diagnostic tool in the phone's Samsung Members App under the GetHelp section and if necessary try Safe Mode > Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. 

Check any sync set up as this can be known to cause complications.

A Samsung Service Centre can help too.

I wish you all the best. Take care.  😎
