Since my update started this early morning I discover this issues on my Samsung (S9+):
1) Google Play can't update the apps because continues closing.
2) Mobile restarts suddently at times.
3) Battery drains faster.
4) All apps closes when using for a bit.
5) Lack of info and support.
6) Apps runs slowly than android 9 and some gets frozen.
7) No option to go backwards on the software.
PLEASE if the new version of the android is not ready, lets us know when the post update fix is ready. Thanks for the efford.
