It's funny imagining people saying this for anything but a phone. "You can only download from the Microsoft store or you should consider your device corrupted." Take caution, but you don't need to rely on daddy Google alone.
Damn, here I was worried I had bricked my phone and made it unusable by loading up my own personal apks when I was trying to learn coding and different app studios.
I feel like I would have noticed if my phone was unusable though...
not funny anymore. Banks and regulatory are doing this in some countries. Their app just refuses to open if users install any app outside of Google Play Stores.
I don't think this person was saying they think all manual apk installs are suspect, just that installing apks from an unreliable source. There are plenty of reliable sources to get apks
you need Google to tell you what safe and what's not? have you ever used a desktop operating system where you usually install programs from different sources?
