Touch Screen Unresponsive Majority of Time
I have a 64gb iphone 6. I've had it jailbroken in the past, maybe around ios8, upgraded to ios9 around september. I had it network unlocked around november/december and it seems like ever since then it gradually became unresponsive. When its unlocked, it opens up apps on its own, types on its own, etc. As if the screen is being touched all over, and then it abruptly becomes unresponsive to my touch all around. Now it's to the point where I can only control for a few seconds/minutes, if ever. I've tried hard resets, soft resets, setting it up as a new phone and everything. I know it's definitely a software issue, how do I go about fixing this? Thanks in advance.
Is this a good question?
