1. Flash official before this update that is May 2021 firmware.
2. Use Samsung max application to block all background data access on wifi and mobile data, allow are per required , keep bk data on for whatsapp, Gmail,
3. I observed is once I start data , phone was freezing and auto restarting now after doing above steps it has not restarted since 10 hrs.
4. I see this is old issue from Android os where lots of apps run in background which consume processing power as well as battery, data.
5. After above steps device did auto restart couple of times but now it has not auto restarted since 8 hours.
It is because of last buggy software update, change motherboard for 6k-8k and never choose Samsung again. Even Brand ambassadors including @CrazyBoy28 raised this on senior level, but Samsung ignored them, what can we do apart from never choosing samsung again and giving them lesson in form of dropping down sales.
My M31 first freeze and then restart two three times by hard started one's or twise ,thrise in a day. May be because of processor heat up and stop working.
I observed is once I start data, phone was freezing and auto restarting.
i visited service center at Neelam chowk Faridabad. without watching they told me to replace motherboard and also share tentative cost of repairing 8000 INR approx.
i will never recommend Samsung to anyone, as they have such type of issue in their costly phones.
