SAMSUNG A51

Just heard half an hour ago from the repair person where I picked up my phone that the SAMSUNG A51 & A71 has a manufacturer flaw. My A51 went in for repair 6 times between 5 Dec and 16 Feb (today) for the same problem: it rebooted on its own 40 times a day (if left switched on). Each time within a few hours of receiving it back it started rebooting. I don't have a phone, I have a rebooter ; ) Or at night, an intermittent flashlight ; ) It has just come back from Samsung Jhb (again) and I sincerely hope this time that it works. I have been without a phone since 5 Dec till today. Appears Samsung doesn't actually care - even though (they can check their records) I have been a loyal Samsung customer for many, many years (cellphones and tv's). Eish .. Samsung.
