Do all android phones let you install an app by opening a file or clicking a link? I would think carriers restrict phones’ capabilities in this regard.
I've never encountered an Android device that didn't allow me to install an APK. Is that an actual thing?
I’m not sure. But as I understand it, in the US carriers don’t just allow any phone to connect to their network, but rather only ones they have whitelisted (I might be wrong). That’s why I assumed they would also restrict loading apps on the side somehow.
