    Is it possible to set a password for sudo on Android? I’ve never seen anyone talk about it.

    on android you don’t use sudo, or if it is possible, it is not the usual way. usually there is an app that controls access, and when something wants to start a new program with the su command (switch user), the app pops up a prompt about whether you want to allow it. this prompt can be implemented terribly insecurely or not (or rather the “backend” of it really).

    the most common root solution nowadays is Magisk. it only modifies the bootloader. it is open source. if you look up how it works, its like a sophisticated malware, but handing control to you

    Sucks that I can’t control sensors with root. Sensors are my biggest fear on all phones.

    you can’t for the modem. but for other apps, you can, if that’s worth anything. to me it does, because some sensors are not gated by a permission (gyroscope, compass, magnetometer, proximity sensor, light sensor)

    what android version do you have? on newer ones there’s a developer setting to allow to have a “sensors off” quick settings tile

    Well, shit.

    if you don’t need the modem, you may be able to safely wipe the partition holding its firmware. but look it up if it is safe for your phone! it should be, but who knows. also, make a backup! not 1, but 3!! it holds identifiers like the IMEI, and if you lose that… you can’t really just think up a new one, or the carrier may ban you and another poor soul

    it is not at all detrimental to privacy. it may be to security. different things.

    of course, until you install something that uses root and mines data. but there are plenty of tools working with root that don’t do that.

    you most probably can’t switch off sensors even with root, effectively. that needs a hardware based switch that just cuts power to the sensor, and requires your physical action to turn it back on.

    Intel ME on android is ARM TrustZone, I think, or at least probably that’s the closest, but take this with a grain of salt.

    but I doubt that a highly complex OS is running beneath general Android as we know it

    afaik the modem often relies on a linux based system
