My iPhone 6Plus’s screen / touch recently started getting un-responsive regularly- and beyond getting touch IC chips changed – I did a bit of research about the causes of this problem and how it has been fixed by others.
I am sharing one such video – which is amongst the best pieces of information / video / tutorial on this topic.
I have great praise for the guy who made this video. Though I have neither opened my iPhone nor have I personally tried this yet – I share this because of the awesomeness of this guy’s knowledge in general – and because this method has been tried and used by others I know- including professional iPhone repairmen and it has worked superbly for them.
