After months of usage, factory reset, and research, I must say Samsung M series is the shittiest series. The restart problem has not fixed, even when the error report feature is enabled.I will not let anyone in my circle to buy these cheap series mob...

I am also facing the same since a month now. It is happening 2-3 times a day.

The issue seems to be fixed in recent Samsung software update.

Both the device and app are updated. Samsung guys say it is issue with whatsapp. PFA their response.

hi, I have M21 and the whatsapp camera photos are getting shifted to right after clicking.
