Recently I found the Bluetooth activated by itself when I restarted the smartphone, the VPN had been deactivated, the account was disconnected from the Samsung store and I had received a call from an unknown number while the phone was off (probably spam), I reported it on Members by sending the data, they advised me to see if the problem was still present in safe mode, in safe mode I found the airplane mode activated (I don't know if it's normal), the Bluetooth was turned off and the VPN could not be used in this mode.. in the same report they advised me if the problem was not present in safe mode to make a backup of the essential data with Smart Switch and save it on the PC, then to do a factory reset without restoring from the backup and if the problem occurs again to take the phone to be checked at an authorized center, I have already done several antivirus scans and everything seems ok, at this point do you think it is safe to connect the phone to the PC to make a backup?
