Vr games not supporting phone after flashing cyanogen mod

For some reason after flashing cyanogen mod a lot of problems came to my phone

1.Cant play videos unless using vlc media player

2.Vr games are always supported when it comes to my phone but after flashing CM it just shows me a pink screen with the ui of the vr goggles with it (TRY VR ROLLERCOASTER AND IMAGINE THE PARTS OF THE SCREEN BEING PINK

3.I cant PROPERLY take pictures and cant save recorded videos

an answer to each question may help

Welcome to the forums. There may be nothing to do to fix this. It may be a bug in the ROM, and as Cyanogen is no longer operating, there will be no fixes for this, unless an unofficial version that an independent developer creates does fix it.
