My LG V30 is less than 3 months old and had been working perfectly until this morning when I ran the most recent update to Android Oreo, and now I have a black screen after I enter my password. I tried restarting the phone, and I can receive texts, phone calls, emails, etc. but when I click on the notifications, which actually appear, in order to read them through, the screen goes black. I also can't see any of my apps to launch them since my home screen is black and I can't make outgoing calls, except from my car when the bluetooth is on. So the phone seems to be OK but for the screen, and I have got to assume it is the update that has caused this. The people at T-Mobile and phone repair techies at a local fixit store have not seen this before and they couldn't solve my problem. Has anyone else got this problem, and how do I fix it?
