I installed the latest Fairphone 4 update this morning because it said it would fixed a problem I had the last couple of weeks (phone restarting without notice). Update downloaded, installed, then I wanted to just restart my phone and nothing, dead. Battery was 3/4 charged. It is not going on with any of the buttons (power and volume up or down). It is not connecting to a computer anymore either. I doubt it is just the battery that decided to die as it was perfectly fine and it happed right after the update. Anyone else have this or know how I might solve the problem (if at all). Thanks!
