Hello.
I have Samsung Galaxy S10 Lite G770F, bought in Poland. I upgraded from G770FXXU2BTF3 to G770FXXU3CTH4, then used factory reset to clean all settings and data; no carrier apps/data. I don't have many apps and I have the same apps as before, same settings, so there should not be big difference. I used BTF3 firmware for many months before the upgrade, so I got used to how it works. I'm also Android user from beginning and used many phones.
Issues I found comparing to previous firmware:
- video stabilization does not work, ironically - when I tried to disable "Video stabilization", then it was a bit better, big issue since S10 Lite was marketed with "Super Steady OIS" (OIS + normal stabilization + optional Super Steady mode,
- Game Booster overlay during Asphalt 9 game now shows ~3,5 hours of playing time instead of ~6,3 hours and the phone gets noticeably hot, battery percentages go down faster too in my opinion. Before update I was shocked how cool is it in game and how many hours I can play. Now that is ruined after update. Game plays and looks the same. It's weird, because in standby or in usual usage (messaging, web browsing etc.) I don't see battery issues at all, but something is definitely different while playing demanding games and the difference is not small.
Other issues not related to firmware:
- I think photos should be more detailed (as for 12 Mpix) and not oversharpened, but I suppose it's Samsung-style 
Could anyone report these two issues to engineers?
Is it possible to downgrade to G770FXXU2BTF3 via Odin and block updates (for let's say - a year)?
If you noticed other issues, please report. Thanks a lot!
