Thank you so much! this solved the issue for me, it was driving me insane. My screen had so many issues, it used to not wake up when opening the phone or go black after 2 seconds of opening, also sometimes had flickering or the screen gave me weird colors before going black. I am out of guarantee and thought that I had to spend a lot of money to replace the screen.
I disabled Meta Services, Meta App Installer, and Meta App Manager, and the issues are completely gone. I don't have Facebook installed on my phone but use Instagram and WhatsApp and there has been no problem with those apps.
