Touchscreens can be common in devices such as game consoles, all-in-one computers, tablet computers, and smartphones. They may also be attached to computers or, as terminals, to networks. They may also play a prominent role in the design of digital appliances such as personal digital assistants (PDAs), satellite navigation devices, mobile phones, and video games and some books.

After touching the hidden button once, press the menu button or long touch the LED image to open the settings. Access the settings menu to customize and personalize the Fingerprint Lock screen to your liking, including options to disable sounds, vibration, show or hide scanner, the date and/or help button, change themes, change time/date/other fonts, sizes, positions and more! Go into the settings to hide the "Help" button that appears when you first use the app.

Note! - This app does not actually scan your fingerprint. That is impossible. It works great as a lock screen, but is great for pranks, jokes, and fooling people. There is a hidden button that will toggle access to the phone. After toggling access to allow entry, you can either scan and be granted access, or you can enter the settings menu by pressing the MENU button or long pressing the LED image. This is all explained in the app by clicking the "Help" button. The Help screen is also shown upon first launch of the app. I am not liable for any actions involving the use of this app and can not guarantee that no one will be able to access your device while using this app. There is currently no reliable way to make this app actually run on your device by pressing the power/lock button so you can not actually make this app run when pressing the lock button on your phone.

Radar is an object detection system which uses the radio waves to decide the range, altitude, direction and speed of objects. It could be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations and terrain. The radar dish or antenna transmits pulses of radio waves or microwaves which bounce off any object in their path. The object returns a tiny part of the wave's energy to a dish or antenna which is usually located at the same site as the transmitter.
