Screen turning black from the bottom
I did a battery replacement and I did something I probably shouldn’t and didn’t need to do, I removed the screen. Before, this phone just had a water damaged (but working) screen and a spicy pillow. Now after power cycling, repositioning the connector, and hard resetting, it still shows this. It’s different every time, but every time it turns on from boot, everything is fine until the apple logo turns greyish. The screen starts turning black from the bottom and spreads throughout the screen slowly as i use it. It also has a similar effect to burn in.
Is this circuitry damage or did the battery expanding inside destroy the screen?
