The final update and nail on the coffin:
I have confirmed that my fix for the camera module has PERMANENTLY FIXED
the two M7s that I have applied the fix to since the date of the OP (July 2014).
"But wait!", you say, "why didn't it fix my camera on my phone? You're a load of bull!"
The answer for that is in post #110
. READ. THE. DAMN. THING.
Prior of you doing the fix to your phone, your camera module has already been permanently damaged and there is no other way for you to fix this but to replace it WITH A NON-DAMAGED CAMERA MODULE, OR OMNIVISION
Let us all be clear of that!
I am lucky that I have done (thought of) this fix before getting the camera module stuffed up.
How did I know that it has fixed it permanently?
I have recorded a video in 720p (on the 3rd of May, 2015, think what it is) from one of the phones (GPe converted, official Lollipop ROM using Google Camera, same phone that I've used on the proof video on OP) that I've got the fix applied for a whopping 1 hour and 15 minutes NON-STOP! The phone heated up alright to a staggering 53 degrees Celsius (as the phone indicates). I was surprised at this stage that the phone hasn't turned itself off automatically thermally, which the phone has on. I did see a small amount of purple tint haze when I tried stopping the recording then opened the camera app again. I immediately turned it off to cool it down. Waited approx. 30 mins to turn it on. Tried it and voila, no purple tint haze. Having to encounter this, I now have a peace of mind that I wouldn't have the issue again, and very confident that it has fixed the thermal handling of the camera module.
Having to rant and vent this out, I DO NOT WANT TO SEE
(hoping for humanity) anyone posting saying that this didn't work, instead, post or say that YOUR CAMERA MODULE HAS ALREADY BEEN PERMANENTLY DAMAGED
prior to applying the fix!
