I accidentally dropped my phone on my keys, and after that the screen is black with only a few colored pixels near my power button, but after messing around with it I realized that the touchscreen is still fully functional (it vibrates when I swipe, since I have a pattern setup on the lockscreen). Is there any easy way to fix this, or will I still have to replace my whole screen?
The part of the device that registers touch is the Digitizer, and the part of the device that produces the actual picture is (well, obvious to me) the LCD. What you must’ve damaged is the LCD because the device still registers touch. Sadly you cannot replace just the LCD, so you will have to replace the entire LCD and Digitizer Assembly. iFixit sells a great Google Pixel LCD and Digitizer Assembly in both white and black colors.
