iPhone 4 camera faulty flickering SOLVED!
SOLVED, READ ANSWER FOR INFO.
I have got an iPhone that i have just repaired (very badly damaged digitiser/LCD) and during testing i have realised the camera function has stopped working. When i open up the camera app, the rear camera loads and works, however when i switch to the front camera, the "retina" stays closed and the "camera-video" switch on the bottom right starts to flicker.
After that happens i am totally unable to use the camera function unless I disconnect the battery completely and reset the iPhone. This isn't the first iPhone this has happened to. It is not a firmware issue as i have restored it several times, and i am also aware that due to the iPhone being damaged this could also be the cause. Just want to know if there is a fix for this issue?
Any help is greatly appreciated!
Update - I have reset the iPhone for the second time and now the camera does not work full stop. fun times.
Update 2 - I have restored with custom firmware, opened up camera app, rear camera works however once i switched to the front camera it decided to **** itself again.
Update 3 - Just realised that it is still under warranty so I will get the person to take the phone to apple to get it replaced for free.
Update 4 - Just got back from the Apple store, had to wait 20 mins and a brand new iPhone was sitting in my pocket :)
For any issues with anything regarding a firmware issue the first things to do is to restore (custom and iTunes firmware). After you have done that and the issue has not been resolved you should move to part replacement (if it is regarding the camera app not functioning properly or a similar issue). If you have replaced the part up to three times and it is still not working (yes it is necessary to replace up to three times, sometimes you will replace a faulty part with another faulty part, the glories of technology) then you will have to assume the logic board has been damaged in some way.
Take back to apple and let them deal with it :) Because the genius's at the genius bar's are so short on time they physically do not have the time to open up the iPhone and check to see if it has been tampered with. All they will do is check the liquid indicator and if it has not been set off and the fault still purists with them then you will get a replacement no questions asked.
