3D touch screen in smartphone. Supersensitive














Nowadays most of the smartphones have super sensitive touch screens.

And sometimes you can use it without physical contact.Just move your thumb or finger over the screen,it will automatically sense the presence.

This happens because of the proximity sensor it has.

Same goes with my Lumia 730,which i have shown in the Video.



But actually the proximity sensor in mobile phones use IR-based proximity sensors to detect the presence of a human ear. This sensing is done for two purposes: Reduce display power consumption by turning off the LCD backlight and to disable the touch screen to avoid inadvertent touches by the cheek



Possibly its not 3D touch,its just the faulty proximity sensor.
