You've waited a bit too much It may be a Manufacturing problem, you should take the phone to the local authorized agent for Samsung in your country they may help.
the issue is that they want me to keep the phone for several days with them and there is a possibility they request factory reset this is not acceptable
You could make a backup for the data using the Smart Switch app search for it, and you got no other options better than this, you tried anything would help before?
they should be able to fix the issue without a factory reset even if the data is backed up with Smart Switch, the recovery after the reset in terms of signing IN and addind my 15 emails is huge it takes several days since I have 300 apps what to do with 2 whatsapp numbers
