1. Enable developer options
Lollipop's Developer Options enable you to tweak the system for improved performance and access various diagnostics, but they're hidden by default. To enable them, go into Settings > About Phone and tap Build Number seven times. This will unlock Settings > Developer Options, where you can fiddle with settings to make your phone even more personal.
2. Streamline your lock screen security
Android 5.0 Lollipop comes with a variety of lock screen security options, from the classic pattern, PIN or password, to the more funky Lollipop options like Trusted Faces, Trusted Devices or Trusted Places. Whatever lock screen method you choose, setting it up should be one of the first things you do with any phone.
If you choose the Trusted Faces option, you don't even have to bother with the hassle of a entering a PIN, you can unlock your screen just by showing it your face. Marvellous.
3. Put Chrome tabs back in Chrome
This isn't a huge problem — and maybe you like having your Chrome for Android tabs spread across your recent apps stack rather than in the browser — but for me it's an irritating default setting. Fortunately, all you need to do to get your Chrome tabs back to their rightful place is to go to Chrome settings and disable Merge tabs and apps. Your Chrome tabs will now be accessible via the traditional button on the URL bar in the Chrome browser.
4. Play the hidden game
Go to Settings > About Phone and tap Android Version four times. You should see a lollipop; tap and hold it and you can play the Flappy Bird-esque Easter egg game featuring the Android mascot.
5. Block non-essential notifications
Priority interruptions are a key part of Android 5.0 Lollipop. The function allows you to determine who your most important contacts are, and silence notifications from everyone but them. Once you get your priorities in order you can enjoy peace and quiet unless your mom's dog runs away or your girlfriend is texting you.
