An amazing tip, many of you didn't know that in your android smartphone you have an built-in video game. If you want to play that game, just you need to do is that:
1) Open your android phone.
2) Go to "Setting".
3) Go to "About Device".
4) Tap 5-7 times on "Android Version".
Boom your android smartphone built-in game is open.
Note: Some times it take more tapping or some times less and other thing is that all android versions have different video games and some of them need more tapping or press and hold your finger when the game is start opening or loading. Most of them are offline and one android version has only one video game in it.

It could be work on any Galaxy... The trick is the next. If you select the call menu and press the next combination: *#0*# you can acces to a secret menu with a lot of configuration to your smartphone. In this menu you can test elements of your mobile, to check its functioning, or simply out of curiosity.  You can check the operation of the loudspeaker, the camera, the colors it reproduces. Although the most useful option is the sensor, which allows us to check if the touch screen works correctly anywhere on the mobile. Only passing the finger will draw a line, and we can see if this line is created or not.
