The Nokia Lumia 1520 I have has started to bug me in the sense that when I unlock my phone it gets stuck on the resuming screen. I've lived with it for a while but its really starting to get on my nerves. I've hard rebooted it, soft rebooted it, anything you can think of short of a factory reset. I don't have a massive amount of background tasks on either. I've looked on this forum and I didn't see anything exactly like this problem so I'm posting it here to see if there is any little trick to fixing this or will I just have to spend a good part of my day factory resetting my 1520 and setting up my phone back to its former glory.
