Whenever i open a game that works in landscape mode, display doesn't record touches many times. And I can't pull down the notification bar at all when the phone is in landscape mode. Please suggest me a solution to this. I'm using samsung galaxy f54....

Finally with oneui 6.0 star trails are available in camera. now you can record star trails with no problems 

I have noticed a few improvements after updating the os. The speed at which apps install has improved a lot and camera has also got some improvements. 

I received One ui 6.0 update today. I haven't updated yet though.
