Number of sensor for g4 plus. Name of laser auto focus sensor?

Hay peeps. I have a reg g4 and it kinda looks like it has the laser auto focus sensor in back. My g4 has two camera sensors called rear proximity sensor and camera activation sensor. I have a total of 19 sensors. I need to know how many g4 plus has and what's your guys camera sensors name are? Thanks. I used sensor list app. Also my rear proximity sensor only gives change in output if I put my hand really close to it. What about yours?
