- Schinken_ 5y agoFrom what I know (having owned two Xiaomi Phones with the 'Remote Functionality') it is a basic IR LED (just like a universal remote). The LED is seated on the top of the phone (like a regular remote) so capturing that light with the camera for analysis would be quite incosistent imho. But worth a try?
