Touchscreen not work - Tested using multiple Displays
I have a iPhone 4S, touchscreen stop work after LCD replacement (Broken).
At first i think it may be from new LCD but after test with another one i have same result, no touch...
Sometimes after plug and unplug flex it start working, but after sometime or reboot no longer work. (This happen with a few trys)
Flex and ports are not damaged, pins are normal.
I have try to clean many times without success.
What can be?
