Hey yall, I was the one who posted about framedrop issues in the previous update. It looks like changing the framerate to 60 in the new update (9.2) helps alot on some newer devices but the way I found out that gets rid of the lag completely is an app called Game Booster 4x by G19 Mobile, its 99c for the pro version (there's a free version with ads) but it got rid of all the lag ingame and now I can play at 60fps with no framedrops anywhere.
It looks like any game boosting mode (including Samsung's default game booster) seems to work as long as it detects the game from your list of apps highly recommend using it doesn't cause any hotness on my device either.
Just wanted to drop this piece of knowledge for yall! (Also sub to the patreon for Robinwood these guys are amazing and I've followed them for a couple months now!)
