perfect. Camera had stopped functioning on my G3 (due to some clumsiness on my part). Followed the steps and disconnect camera ribbon, then reconnected and reassembled. Now all functioning perfectly.

how was it not functioning? Mine suddenly wont even detect that there is a back camera and I am debating whether to try this and risk ruining the phone or just spending the extra cash and having it done professionally since I can't get a new one until april.

Mine the camera started crashing 'unfortunately camera stopped' but the selfie cam worked. Reset did nothing have to try this.

Will the phone work with out the camera in it?

Excellent guide.    Bad auto focus, replaced -> works !

Would add in step 6, top panel is held on by small plastic tabs on the edges.

As with all electronic dis/assembly, make sure take appropriate anti-static precautions.

This is old thread. But i Changed of Android Version (7.1 now) and changed Camera part… and still crashing / detecting only front camera. Seems a motherboard issue. Game Over.

And actually had 1 motherboard change from D855AR to D852… what a crappy motherboard. It fails screen flex / gpu / Sim - MicroSD slot… and this camera thing… This is all about heat issue.
