Flash the ROM again. Seems like it didn't flash properly. My display settings opens perfectly and I have the screen recorder on my status bar tile.
This is the PE9 thread, so I'll assume that's what you're on. Therefore you need to clean flash PE10. If you want to use a custom kernel, you'll have to flash that after flashing PE10.
kernel will get changed automatically.
Clean flashing to PE10 isn't mandatory.
There is no mirror for PE9 builds. They've been deleted permanently to make space for newer ROMs to come.
Never mind, it's working now. Google pay, Netflix and other apps that need safety net to pass is working now. Uninstalling xposed solved the problem.
