I am wondering if Android notifies the user daily to update their OS like Apple's iOS does? I'm a long term iOS user and the automatic software updates implemented recently has me considering switching over to Android. I've never used or owned an Android and am curious what the experience is like.
As MikeT said, it depends on the device.
For tbe most part, No matter how much a device screams, you can ignore the update. You can also disable auto checks and get no notifications until you check yourself.
That said though, it depends. Samsung rarely do updates, like quite a few OEMS. Google Updates the Nexus line Every month, though it is optional security updates that take little time to do.
The reason updates are so off-hand is because of a system app called 'Google Play Services', which does a lot more than I can explain. It negotiates app connections, Grants the user to use GApps and the API'S included, and can add new features-no OS update needed. Neat, eh?
