LG V20 cannot attach files & Fingerprint Reader Not Available


    My T-Mobile LG V20 can no longer attach files to anything. The app crashes and says "Unfortunately, Documents has stopped." I tried clearing the cache's for both the app and the system. Also did a factory reset. Did not change anything.


    Also the fingerprint reader stopped working completely and is not available in the settings menu at all. The factory reset did not help with this either. It was running on the latest update up until this month just fine. What can I try? Is there a way to re-flash the original T-Mobile ROM? Would that do anything?
