MD_18 , Dec 22, 2018 : I'm currently using open beta 9 and i read a lot about random reboot thing in this forum. personally i didn't notice it till now. so i was reading an article on chrome and no other app was in the background. suddenly my screen goes black and nothing is working and suddenly the pin screen came up saying your phone was restarted and now I've enter the pin. first of all its weird. second thing is i didn't see a bootup animation or anything and all of this happened in 5 seconds so I'm pretty surprised with this problem. Also i did a clean install so i don't know exactly why this problem is there. i reported it and just created this thread to tell you guys who were not believing as i saw on older threads. this random reboot thing is real deal. Thanks.
