[Q] Blue tint, not everywhere and not all the time
Search did not reveal any post with this particular screen defect.
The phone is a collegue's of mine so I can't troubleshoot it directly or tell you baseband etc. It's brand new, 4.2.2, and a 4G so probably i9505 (bought in europe, sweden). It has not been droppped, collegue would have said if this was the case . What collegue told me was it was like this when collegue got it.
Sometimes screen becomes blue, but only parts of it. You can see this clearly on the attached photos. It's most promient on white areas, which are not white at all, but, well, blue!
Especially note the partial blueness of Whatsapp icon borders.
Screen lock is being used, blue tint appears on lockscreen as well.
Could not isolate when this occurs. I did not experiment much with the giroscope, don't think that's it. I also seem to recall viewing angle not making a difference. I did have it in my possesion for 30 min, during which the blue tint did not occur. Auto brightess was already off, took brightness down 2 or 3 notches. This is what I changed in settings -> display:
- Screen mode: standard
- Auto adjust screen tone: off
- options that should not be relevant
- Screen timeout -> 5 min
- Wifi -> off
After this I gave it back to collegue, about 10 minutes went by, collegue took phone out of pocket and activated screen. Now the blue tint was back. At this time I took the attached photos a well as did as screenshot capture, which is not attached, but the blue tint was present there as well. It looked exactly the same as the actual OS/what I had seen with my eyes.
Device was a this time lieing on a flat surface.
I told my collegue to turn in the device for another one, but collegue would rather try/hear about/research a DIY- solution first.
Is this a common defect? Is it sw or hw? Can it be fixed? Etc...
(black rectangles is censoring)
edit: it seems to occur when the phone's screen has been turned off for a couple of minutes. Yesterday I unlocked device after being dormant for some hours, blue tint was there. Screen timed out by itself and when I unlocked blue tint was not present. Waited 4 min then unlocked, and sure enough blue was back. Turning on-off screen solved it once again. Also tried repeatedly locking-unlocking without blue tint reappaering.
