iPhone screen issues
I'm having an issue with my iPhone 6 Plus screen after replacing it. Basically the whole screen is flickering horizontally when unlocked, however on initial steer up and on the home screen it's fine, it only happens as soon as it is unlocked.... I have disconnected the cables and reattached them, disconnected and reconnected the battery and performed an update and restore, still no luck.
I have attached two images, one when the phone hasn't just booted up and not unlocked and the other as soon as Iran unlocked
Is this a software issue? Or will I need to install a new logic board?
Any help and advice would be appreciated
Thanks
