Broken Screen Prank

If you can enjoy a good prank - you will appreciate this one. Make your friends believe that your phone screen was actually broken - when in fact this app is just a funny joke. This prank works like magic - surprise your friends!
Make everyone believe that your phone screen has cracked, when in fact there is nothing wrong with it. You can trigger the prank by pressing the start bottom, afterwards you need to shake your phone, touch it or even whistle and the cracked screen will appear, accompanied with the right sound (keep in mind that you decide what will be the trigger for the cracking to appear). After tapping the screen again it will go back to its normal state.
Repairing a broken screen can take time and energy. It may cost a lot of money, what can often move people to buy a new phone or repair it by themselves. This is why this prank is so authentic and real. If you do have a cracked screen for real, you can repair it, but it takes time. You just need to follow a few steps and you can enjoy your phone again.
A practical joke is "practical" because it consists of someone doing something physical, in contrast to a verbal or written joke. For example, the joker who is setting up and conducting the practical joke might hang a bucket of water above a doorway and rig the bucket using pulleys so when the door opens the bucket dumps the water.
Practical jokes are also common occurrences during sleepovers, whereby teens will play pranks on their friends as they come into the home, enter a room or even as they sleep Modern and successful pranks often take advantage of the modernization of tools and techniques. Pranks can also adapt to the political context of the era. Students at the Massachusetts Institute of Technology (MIT) are particularly known for their "hacks". Practical jokes differ from confidence tricks or hoaxes in that the victim finds out, or is let in on the joke, rather than being talked into handing over money or other valuables.

Breaking your phone screen can damage your phone proper functioning. Mobile phones send and receive radio signals with any number of cell site base stations fitted with microwave antennas. These sites are usually mounted on a tower, pole or building, located throughout populated areas, then connected to a cabled communication network and switching system. In areas of low coverage, a cellular repeater may be used, which uses a long distance high-gain dish antenna or yagi antenna to communicate with a cell tower far outside of normal range, and a repeater to rebroadcast on a small short-range local antenna that allows any cellphone within a few meters to function properly. When the mobile phone or data device is turned on, it registers with the mobile telephone exchange, or switch, with its unique identifiers, and can then be alerted by the mobile switch when there is an incoming telephone call. The technology that achieves this depends on the system which the mobile phone operator has adopted. The technologies are grouped by generation. The nature of cellular technology renders many phones vulnerable to 'cloning': anytime a cell phone moves out of coverage (for example, in a road tunnel), when the signal is re-established, the phone sends out a 're-connect' signal to the nearest cell-tower, identifying itself and signalling that it is again ready to transmit. This problem was widespread with the first generation analogue technology, however the modern digital standards such as GSM greatly improve security and make cloning hard to achieve.
