Can I control a cellphone's lcd (+touch screen)? I had an Xperia txt pro just laying around and tried to revive it. I burned it like an idiot using 5v in the battery pins by accident :/
So I decided to read it apart and got to the lcd, can I use my Arduino Mega to control it? Bc I have no idea how to use it.

These are the pins
No. For two reasons:


You will struggle to find the pinout of the TFT (or even identify the model). It will have most likely been custom made for the phone.
The Arduino doesn't have a GPU to drive it. Arduinos need a TFT with built in GPU since they lack the resources to drive one directly.
