touch screen freezing repeatedly
Actually I've searched several places into this community, but couldn't find an answer that fits what I suppose is the problem.
What is happening is the constant and persistent freezing on the screen of my Iphone. When it happens the devise blocks and the only way to resume working on it is the light off of screen and start that all over and even some times doesn't work properly and I have to do againi the previous steps.
I've already tried several processes including reset the phone into its factory configuration, but didn't work.
Is there anybody able to inform any possible cause and possible step to fix it?
Thanks you all in advance for the attention and cooperation.
