This question already has an answer here:

I want to root a tiny cheap smartphone that my 6-year-old grandson uses.

He's a real techie, but he's always changing his password and then forgets to tell me so that I can store it in LastPass. So I want to install a parent protection app, where I'm the Admin, and he's a normal user (as on Windows 10). I already have Kaspersky Safe Kids on the phone, plus he has downloaded a lot of games.

There's no space for a parent protection app, and he's not allowed to use stuff like Chrome, so I want to root the phone to allow me to remove pre-installed stuff.

Here's my question: What exactly happens after rooting?

Is a password still needed for the first login after rooting - because I'm sure he's forgotten it.

Will every app have disappeared? (That would be OK.)

Thanks.

    After rooting, you (means the apps and processes on your device) get the ability to get privileges of UID 0 - the super user or administrator. So the system resources which were not available to you (as a non-privileged user), become available. Now you can do everything; remove prebuilt apps from /system partition which you couldn't access before; watch your phone's inside things in more detail, break your phone in a second etc. Password will work as it is, except you will have ability to remove it easily. Will every app have disappeared? No, only those you make disappear. – Irfan Latif Jul 1 at 17:58

    Welcome to Android Enthusiasts! This seems to be an XY problem. By removing preinstalled apps you won't gain any additional (user) space – as they are installed on the (read-only) /system partition – while the additional space you need would be on /data. So for that it is sufficient to disable those apps, and then delete their cache and data. That would be all you'd get in free, usable space by uninstalling them anyway. Apart from that: have you seen our rooting tag-wiki? – Izzy Jul 1 at 18:08

    @OldGrantonian I hope you didn't miss my warning: Now you can do everything; ... including break your phone in a second – Irfan Latif Jul 1 at 19:55

    @OldGrantonian yes, root gives you the ability to uninstall pre-installed apps – but you wouldn't gain additional space by that. And space is what concerns you here. // I could write up an answer for your real question, expanding my above comment a bit – but that would answer what you need to know (gaining space), not what you asked here (affects of rooting). – Izzy Jul 1 at 20:57

    @OldGrantonian then this could be a good source if you want to learn in a bit depth. – Irfan Latif Jul 2 at 9:01
