iPhone searching signal constantly
hello friends, I fixed complete display/touch panel of a friend after the fall of this.
in addition to this problem the phone is always in the state of network research, can someone help me on what to check?
the problem occurred several days of use after the fall of the device and not immediately, then worked with to type broken for several days.
I have tested this method: reset network/airplane mode, restore iphone via DFU but doesn't work..
Thank you to all!
And sorry for my english..
