So i recently dropped my iPhone 7 Plus and now my rear camera isn’t working. The front camera works perfect but the rear doesn’t. The rear only works when i click the “x2” button, but that’s it. And it also fell on the front so i don’t know why the rear camera isn’t working. I have tried mostly everything. What can i do to fix it? Will i need to replace the camera?
My guess is that you may have damaged the camera in some way, shape or form. I would try replacing the rear camera and see if that helps. iPhone 7 Plus Dual Rear Camera iPhone 7 Plus Rear-Facing Cameras Replacement
Just replace the complete rear camera unit. It will work again. It happened to me as well. I dropped my phone and damaged the rear camera internally. So after replacing with original it started working again
