Multi-user on phones
Google added multi-user functionality to Android in 4.2 Jelly Bean, but it was only enabled on tablets. That makes a certain kind of sense as tablets are more likely to be used by multiple people on a regular basis, but there are plenty of situations it could come in handy on phones as well. Android 5.0 finally makes that a possibility.
The new profile switcher can be accessed from the quick settings drop down. Simply tap the user avatar and pick from the accounts you have on the device. By default it’s only you and the guest account, but you can create accounts for kids, other family members who might borrow the phone, or whoever else you want.
The guest account won’t have access to any Google services or your data, but the pre-installed apps are all there. Android Lollipop also allows you to allow or restrict calls on the guest account as well.
This is really just the tip of the iceberg–Android 5.0 has more changes and revamped features than any previous version of the platform. Google really went over every detail this time to build something truly fantastic.
