Has anyone been able to bring an unresponsive / dead LED back to life?
The blue LED on mine is dead. Red and Green work but Blue doesn't light up. A white notification looks yellow and any color that requires blue is either a dim green or dim red.
Quality control on the N4 is so frustrating ... you return for one defect and the next one has a completely new defect. F' this I'm done with it!
Resetting the phone made no difference. Guess it's going back.
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...

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.
Hi! Something went wrong with my phone today. I was using it today and then it flickered (2 flickers).
After the flickering, there's a green tint (very minimal shade but still noticeable). It's not as deep black as it was before.
The flickering happens everytime I boot the phone and unlock the phone. Help. I hope this is not hardware issue.
A dimmed Red LED stays on all the time on my Galaxy S4. If i turn the phone off it still stays on until i pull the battery out and as soon as i put the battery back in the Red LED turns back on. It's not bright red like when you connect the charger, its dimmed down. I almost sure this is a hardware issue but not sure exactly where and i no longer have warranty. (notes: screen is cracked from the bottom near the home button, not other damages) Any one have had this issue?
Thank you!
Recently ive had an issue where the screen goes completely black out of the blue, the only light coming out is a tiny line of white at the very top of the screen. And the only way to fix is to do a manual restart by holding down the power buttons. Is this a hardware issue? Does anyone know of any know issues like this?
