The battery life after third beta update has improved a lot, Samsung has fixed the battery drain issue. I haven't seen any bug or slow down so far it is almost stable now.
It had been 10 days since one ui 3.0 beta 1 rollout. But after that we didn't receive any beta update. We are not getting treatment like s20 series.
After updating the phone on October security update, me and many other people facing ghost touch issue on Galaxy S10 at the bottom part of screen 2-3 times a day. Please fix these as soon as possible, its quite annoying.
