My situation is that I have a phone that works fine, a Samsung Galaxy A5, except for when I'm in my work building and the road it's on. By 'not working' I mean that it won't unlock, I get no response and then have to do a hard shut down to restart it and it will last twenty minutes or so before repeating the process. I've tried keeping the phone in flight mode to see if that makes a difference and it didn't, the software's up to date and no one in the building has the same problem... I've had it fully charged but it doesn't seem to be power related and I am now at a loss.
TF's seems like the perfect place to ask - any ideas?
