I'm sure you've resolved your issue by now but I'll add an answer as I just had this issue and spent hours searching the web trying to figure it out. It's a grounding issue with the main board. Underneath the board on the lower left side, under where the battery plugs in, there's several contact points that when you switch frames the board grounds out on. To be on the safe side I covered all of the contact points with Kapton tape and reassembled the phone. Powered it on, opened the camera and no message, closed and reopened several times to confirm it worked without issue.

HI, could you tell me what contact points you mean? I only see the contact points that work in conjunction with the power and volume buttons on the side of the phone. If I cover it, the buttons won't work, right? I'm having a similar issue where the camera apps keeps failing after a screen w/ frame replacement.

Same issue for me where rear camera doesn't work and front camera is fine. I took care with disassembly to ensure nothing was damaged, so not sure what went wrong. Only caveat is I haven't put in a SIM card yet as I lost my SIM card tray.

Did you find any solution ? I don't know which contact point you mean. I still have a camera failure after screen replacement

I've actually found one that solved mine. I found a YouTube video after hours of searching that said that Intl camera replacements didn't play well with us models. Went to ebay and purchased one that said us model replacement cam, ordered and installed and it fixed it. Hope this helps.
