Practical Scenario 1: Samsung Galaxy Note 20 Ultra Restarts Randomly After Update

Note 20 ultra keeps automatically restarting after update

Started happening after the new update. Every update this year has made my phone have some sort of problem. I am missing calls and notifications because I don’t know it restarted and i keep having to enter the pin to turn it on. It happens multiple times a day sometimes once a day. Tried everything except factory reset and no I’m not doing that. This is obviously a firmware issue samsung has had problems with and I wouldn’t doubt it if they’re doing it on purpose like apple did to make us buy the latest phone. Wouldn’t be surprised if this post gets taken down since it violates their rules for speaking out about a product I paid for and have been a loyal Samsung customer with many of their products including a neo q led I have to return since it came a month late and broken to bits. Gotta love this post pandemic excuse lol.

Practical Scenario 2: Samsung Galaxy Note 20/20 Ultra Restarting At Night By Itself

Note 20 and Note 20 Ultra restarting at night

My husband’s Ultra randomly restarted two nights ago. It didn’t give him a notification or anything, but an app that starts up automatically after restarting the phone woke us up at four in the morning and that’s how we realized it happened. When I woke up this morning, I noticed that there was a notification that my Note 20 had restarted, and his did as well.

We checked our settings and we both have the auto restart off. Does anyone know what could be causing this? TYIA.
