Proximity sensor not working
Ive recently changed the front camera and proximity sensor from my iphone 5, first i used a part that i ordered from amazon, changed it following the instructions, and proximity sensor is not working, i thought i might be a faulty part so i ordered one from ifixit.com. tried one more time changing the part but still no luck, the front camera works just fine tho, dont know why might be causing it and i really need my proximity sensor to work, any help is appreciated
