Touch screen going a little crazy
So I recently replaced my screen and digitiser in what felt like a smooth replacement with no hiccups. I turned the phone on and everything was working as normal. The next day I was using it for a while when all of the sudden the screen stopped recognising my touches and what began what I can only describe as "jumping around", like phantom touches were being made in different areas of the screen and if I were to scroll up an app like Facebook of Safari, as soon as release my touch it would scroll back to where I started. It also felt as though even after my finger is removed from the screen, it would still appear to be held on there.
I managed to reboot my phone and the problem would disappear then maybe reoccur anywhere between 2 and 15 minutes later. Sometimes simply putting the phone to sleep and unlocking it will ease it for a few minutes as well. The randomness of the occurrences are what's throwing me off. I'm going to reconnect the screen shortly but was wondering if there's any other things I should check under the hood whilst I'm in there?
Also I made a fresh install of iOS 9.3.3 in case it was a software issue or bugged Cydia tweak but the problem persists.
Thanks in advance.
Is this a good question?
