My phone has done this sort of "flickering" trough the different brightnesses for a while. Now it has begun going pitch black and I can't get the screen on unless I use my both hands to create some pressure by gently twisting my phone from the edges while pressing the lock button. There are few cracks in the screen, sure, but my other phones have not done this. Any ideas? Can I maybe somehow try to get it working?
I think it's about some wire inside being loose from some edge but I can't be sure?
Just as a compare, I've had few phones earlier, and I'm not talking about the NOKIA's undestroyable one's but just a touchscreen smartphones from brands like samsung. I have had several cracks in the screen so that literally pieces have been falling off but it still did work. I've had one of my phones spent twice at least 1 min underwater and nothing else broke but the on-off switch, which caused problems later on.
