If you phone is randomly turning off, without having to reset your phone, you'll have to change you wallpaper to a static image. No dynamic or short video. Both for homescreen and lockscreen. I also turned off always on display. I haven't had issues since then. Hope this tip helps!
looks like the cause of the crash is always on display. after someone here suggested disabling AOD, I disabled that but still rebooted. however then I disabled fingerprint indicator as well. so far so good. an hour straight without a single reboot in my pocket whereas before it was happening at least every 10 min. I have a video set as lockscreen wallpaper
edit: the real culprit here appears to be the video wallpaper. removing that stopped the crashes without disabling AOD.
I have video wallpaper for my lockscreen, and I didn't remove it. I only disabled AOD then re-enabled AOD and changed it from Landscape to Portrait and everything is fine now.
they do of ur dumb about it. It would only cause a burn in if you leave your phone on for a long time with the brightness up. Otherwise, you wouldn't get a burn in with a static image.
