The digital zoom will of course fix the green tint, you will simply be cropping the picture taken by the cmos.
I believe that this is a firmware issue myself - rather than a hardware one - simply because a hardware issue with the cmos would not be consisten for all users - differing batches of the sensors would work better than others. As far as I am aware this is a issue for all p1 user at this time.
I for one am confident that this can be sorted with a update from SE. Fingers crossed! |

Hm, someone able to check if the tint goes away when using the BST-33 battery that was in the prototype? |

just tested with a 33 and the green tint is still there in all its glory. its gotta be the fw - SE wouldn't have changed the cam from what they used in the proto - would they? |

I tested my new P1 on a white area of the wall, at 30cm range.
I took one picture in the horizontal, then rotated the phone 180 degrees and took another picture of the same place in the wall.
This way I try to eliminate possible interferences of light conditions on the wall, and also colour variations on the wall paint.
Comparing both pictures, I see no green tint and no perceptible differences.
In fact they are so similar the look like a copy of one another.

About the topic title "... (It's a Cmos Defect I believe)"
I'm no expert, but I think it's not CMOS because there is something more prone to color aberrations than the CMOS -- the lens!
I notice the P1 has a somewhat thick glass in the front of the lens.
Maybe it's that glass that is creating the green tint?
To create a color aberration with a glass it's only needed a microscopic imperfection on it, or even a bad positioning (angle) on assemby.
My two cents... |

2 pages earlier I have posted three examples. Two of those were as you mentioned. Try on a brown/yellow surface. You'll see the difference.

I may try, but the simple fact of trying defeats the purpose of saying that's a CMOS defect.
Because *white*/*gray* is a neutral colour, and one which has the Red, Green and Blue components at the same intensity.
The colours you are referring don't.
Now, there's another thing called auto-whites calibration, and that's something purely software made.
So if the auto-whites calibration doesn't work great, that's someting that unfortunatelly also happens in many comercial cameras.
It's a software only thing, and software is fine tuned for real pictures line sun, beach/snow, clowdy, sunset, tungsten (etc), not white sheets of paper/white walls.
I'm not saying that there is no bug OK???, but testing it against anything unrealistic you may get unrealistic auto-white results.

I also don't say that this is a CMOS defect. In your previous post you said that you haven't seen the green tint. That's why I refer to my earlier post.

just out of curiosity as i haven't read the entire thread, but are you guys all using models purchased when the phone was first released?
Maybe it was a quality control issue on the very first batches of phones?! |

Could be the case - althought every single production p1i unit displays the green tint (well - all except one it seems!)
if more users did report that their p1's didn't display the green tint but had the same fw version then i would consider a quality control issue. |

Well, i got my phone about 2 weeks ago and I have the same problem. One corner has a magenta cast while the other has a greenish cast. Sigh. |

...am I imagining things, or is the picture pretty clean at first when you open the camera- app? Before it gradually ends up looking more smudgy? |

still there - i'd wait to see if the next fw update fixes anything...
Although the problem really isn't that noticable for day to day shots |
