My both cameras and flashlight are not working when I touch on camera , and I get a black screen , the camera’s temperature is very high . I bought a rear camera and I changed it ,but it didn’t work ,problem remain. HELP me
Try replacing front camera flex ribbon cable assembly.
I see this got fun real quick lol. So you don’t have a camera ic but rather a camera ldo (low drop out/off). This regulates voltage to both cameras and is usually the culprit if both and only if both cameras are not working. As for it being the proximity/front camera I highly doubt thats the case. Almost always the front camera, if damaged, will short the phone into a red screen/reboot. Rear camera rarely causes this to happen. If your camera ldo is damaged or not making proper contact with the pads underneath both cameras will not respond. Honestly let me get a few more beers in me and I’ll make a quick video to show you lol.
Ok Ben. The proximity sensor is a ambient light sensor. ALS. When you make a call and put the phone to your ear the light is reduced. The sensor switches the LCD pmu to turn off the display and the display pmu powers the touch. This function is to stop you dialing or pressing buttons with your ear. The ambient light sensor also controls the camera functions such as auto flash as when the light level is low the sensor will activate the flash. The sensor also works with auto levels of the camera such as exposure, auto white balance etc. ALS also controls the screen brightness during daytime and night night time. The ALS is a data signal converted from 1.8v grape touch rail. When the data signal is inaccurate this can cause problems with any of the above.
