good enough but I can download "pixel camera" app to get all the features of stock pixel camera? Including magic eraser, unblur etc?
Yeah, I'm pretty sure that's how it works, I think I downloaded it once just to try the camera-translate feature.
Does GOS give me option to disable any internet access for any app? Help would be appreciated 👍
Yup, %100 sure about that one. You'd have to root your phone on stock to be able to disable Wifi for an app, but GOS lets you do it easily with a simple permission toggle. I do this for Gboard, as I like using it but don't want Google to be in my business.
