I have Samsung s21plus problems are where you find Samsung phones #list of issues
lagging and over consumption of ram,
Camera issue both front and back,
Charging takes a long time ever,
Apps keeps closing by them selfs,
Cellular keeps disconnected,
Touch interface while game is in and out.
And they are **bleep**ing sucking our hard earn money.
Yes, there are issues. However, some of the app issues are because the specific app developers haven't updated their apps for 12/4.0. I'm waiting for 3 apps to be updated on my end.
