Chosen Solution
I have a Sony Xperia Z3 here and after a screen replacement the front and back camera no longer work as well as the flash. When I plug the rear camera in the phone overheats a lot! Any ideas on how to fix this would be appreciated! Thanks!
I’m having A- Z same problem .. After replacing my z3 screen , back camera front camera and flash not working anymore.. Also flashlight toggle disappeared from home screen .. I think problem is related to flashlight . When I connect my back camera the phone heats up and battery drains by 1 % every 2 minutes ..But when back camera is removed battery drains by 1 % every 2 hours .. I tried every thing from factory reset , repairing through sony pc companion , tried other camera apps , changed camera sensor etc .. I came into point there is some short near camera or problem is due to flash (As flash light is also not working and flash toggle has disappeard from home screen . Also please note on diagonistic front camera shows up but back camera doesnot shows up .. In camera app when clicked I get a message " Unfortunated camera has stopped " .
I send the mobile to repair shop and he solved this problem by change the camera ic
Try another front and back camera. Not sure how you’re having this overheating issue as I’ve replaced around 10 Sony Xperia Z3 screens. Did you put in the plastic mounting bracket for the Back camera? Including the metal mounting bracket which is held by the housing frame of the phone?
This may be a camera application cache problem. Clear the Camera cache in the settings>Application>camera. Then Clear the whole Application Cache in Settings>Storage and memory>internal memory>(swipe down to) Clear the shared application memory (or smthg like that). If clear the camera cache cannot solve the problem, you can try reconnect the camera flex cable, cause the flex cable maybe loosen when accidentally drop or hit. This Sony Xperia Z3 Teardown can help you disassemble it.
