Screen goes crazy everytime I lock my phone
So, I replaced LCD+touch screen on my cousin's Redmi Note 11, tested it before I glued it up and everything was ok (didn't lock the phone upon testing) and started assembling it back afterwards.
I glued it up and returned the plastic frame, but before I started putting screws in I wanted to power it up once again to check if everything is still ok. This time I locked it during testing and once I wanted to unlock it my screen just went all purple making it impossible to do anything. I disconnected the battery to turn it off, connect it back and powered my phone up once again. I came to conclusion that everything works great and all in order untill I lock my phone with power button.
I've never experienced problem like this one, hopefully there is some solution.
