Your mobile phone screen lights up during a call primarily to facilitate easy access to call controls and features. The proximity sensor detects when the phone is held close to your ear, turning off the screen to prevent accidental touches. When you move the phone away from your ear, the screen lights up again, allowing you to see the call interface or other notifications. This design enhances user experience by preventing unintended actions while on a call.

Mobile phones are incapable of carrying a projector bulb powerful enough to project focused light more than a foot or so, although it is possible to build a laser pointer into a mobile phone. However, even mini projectors require more volume than modern mobile phones contain, so unless you have some old arm-sized mobile phone it will not have enough space to contain a miniprojector.
A B-Graded phone is in most cases slightly used, and commonly have a few light scratches and scuffs but is in good working conditions.
A light switch can be controlled by a phone through the use of smart home technology. By connecting the light switch to a smart home system or a smart plug, users can use a mobile app on their phone to remotely turn the light switch on or off. This allows for convenient and customizable control of the lighting in a home using a smartphone.
