1) Enable Developer Mode
This is one of the more widely known tricks, but it’s important nonetheless, so we are going to include it.
Navigate to Settings > About phone and tap on your phone’s build number seven times. You’ll get an onscreen countdown, eventually followed by a message saying “Congratulations, you are now a developer”.2) Change the Animation Scales
“Window animation scale”, “Transition animation scale” and “Animator duration scale” from 1x to 0.5x. Granted, it won’t actually make your phone faster, but it will make it feel faster.Go to Settings > Developer options and scroll about two thirds of the way down the list to find the necessary options (you’ll need to have first enabled Developer Mode).
3) Locate Annoying Notifications
Do you keep getting an annoying app notification, but you’re not sure which app is causing it?
There is an easy solution — just long-press on the notification in question, and your device will tell you.
4)Secret Game
Another well-known Android Easter egg among old-timers, the secret game might not be so obvious to newcomers.
Lollipop and Marshmallow’s game is based on Flappy Bird; it has the same gameplay principle but has had an Android-themed makeover graphics-wise.
Head to Settings > About phone and tap the device’s version number several times. Eventually you’ll be presented with an on-screen lollipop or marshmallow depending on your operating system. Continue to rapidly tap the center of it and the game will launch.Reference:[Please login or register to view this link]
