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.

This isn't in anyway a 'cool' tip or something that will change the way you view the iPhone all together, but it is a little trick that has saved me from a lot of frustration since learning about it. 
For the longest time whenever I made the mistake while I used the calculator, I would just hit the 'C' button and zero the calculator, and start over. But, if you are looking just to remove the last number of what is appearing, all you have to do is to swipe left or to swipe right in the black area surrounding the number. 
It doesn't seem like a lot, but for someone who is constantly using a calculator for the work that I do, it is definitely something that I greatly enjoyed figuring out as it has saved me a lot of time and effort since learning about it.

Have you ever been placed onto hold by an automated computer system when all you wanted to do was go and talk to a human? well on essentially every automated system there is a bypass to this! simply type 0 on ANY phone (landline, cellphone, etc.) and you will automatically be patched through to a human! Stuck talking to the automated systems is a thing of the past with this simple tip. Talking to an automated system will never result in the system mixing up call the technology department to something ridiculous like end call. I personally have used this tip to save tens of hours that would have kept on hold with an unrefined program. 

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.
