it's funny how they release a new phone now all of sudden, this phone is acting up 🤔 💭 are you guys trying to force us to buy the new phones by messing with up with the new update 🤔. I think Samsung want to be sue

This is generic cut copy paste info. Android users already know this and it doesn't explain the sudden mystery signal drop with a Samsung phone, particularly the S21 Ultra 5g. I had this phone replaced four times over since 2021 because of faulty firmware. Samsung was well aware of the issue but didn't seem to care. Guess it is about $

I've done all those things and still nothing. Even change Sim card. It keeps losing service it says It can't find the Sim card. What I find weird is that my brother s21 ultra does the same thing but 3 other family members with different phones it doesn't do that.
