i have the scrolling issue i know what cause it after multiple unlocks and locks the issue occurs but if you lock the phone and unlock it it will be fixed as for crashes GTA has not been updated for 2 years so it's app problem not your phone if you look at the reviews you will understand
It seems that after Oreo update. A lot of bugs and there is no notification for any other thing but only miss call, emails and sms. my other messengers does not show on the glance screen. IT does not have a LED notification and I have to rely on 3rd party software.
