One for the record - just hung up a phone call and device froze with an interference pattern on a grey screen - photo attached.
Unit a few days old - usual installation (HD Tweak, S2U2 etc). First occurrence - latest installs - galarm_0.9.8.3 and glight_0.5.
The latter app manages the backlight & light sensor....
Fixed with soft reset btw.

hi!
I recently bought a xperia and noticed that the screen is flickering when you turn off the automatic adjustment and turn the screen to maximum. Is this normal or should i return it? its very innoying. It's the light in the bottom of the screen that flickers.
I would return it. Mine does not do this, so I wouldnt consider this "normal"
seems that you have a defective retroillumination led... return it
yeah, definately not normal - mine doesn't have this issue
I also recently received my X1. I also note that the light of my screen flickers but only with certain software. It vibrates on the left when loading windows, and on the black bar in touchflo3d between the start menu and the clock ... I can't see if it is a hardware problem and therefore if I should get the guarantee
I am having a problem with my Galaxy SI-9000 screen. It suddenly goes black and have to pull the battery to get back the screen. However when the screen is black the phone is still working because if I give a call the phone rings but the screen is black and can't see any thing? This started happening from yesterday, since then it has happened twice what may be the problem?
I am testing an application I have written(for battery use) and it is accessing the GPS and the MIC every one min.. can this have any relation with the sudden screen black outs?
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.
I'm having a couple issues with my nexus 4 after upgrading manually to Lollipop with the system image from Google Developers.
Sometimes, when the screen goes idle and turns off automatically or when it's turned off manually using the power button, the screen flashes on a higher brightness and shows the lockscreen before turning off. (I'm guessing the desired result is that the lockscreen should appear 'on screen' after the backlight is completely off).
What this causes is that when turning off the screen, the screen dims with the animation (fade to black and turn off), but before (and sometimes after) the animation is complete, it flashes for a few milliseconds displaying the lockscreen/background, even when locking the phone inside an app.
I could upload a video of the issue at a later time.
This bug didn't happen on any version/rom that went through my phone (many stock, many custom). Although I haven't tried installing another 5.0 ROM / AOSP.
The update also brought back a [hardware?] issue this Nexus 4 unit also has had since I got it. When dimming the screen using the brightness slider, sliding to the lowest setting turns off the backlight completely (effectively making the screen pitch black instead of dimming). This issue has been reported before and I was using Gravitybox to override the system lowest brightness level. Could these two issues be related? (Note that this issue didn't trigger this behavior before).
This issue has been reported by other users here:

http://forum.xda-developers.com/nexus-4/help/problem-nexus-4-brightness-t2052857
https://www.youtube.com/watch?v=dvgt17sKQsU < this shows the screen going pitch black at lowest brightness, it happens either from the widget, the slider, and the option in settings.
Any ideas on why it happens or how can it be corrected?. Do you also have this issue?.
Many thanks in advance.
I started to have this weird problem all of sudden on my phone where the screen flickers on different apps, a solid color of thing that's being displayed on the screen comes up from the bottom of the screen which covers up more than half of my screen and sometimes the whole display.
I installed one of the screen filter apps from the PlayStore which fixed the problem by having an overlay on the screen but the brightness has decreased so I am unable to see the screen n bright light(like outside), I can't figure out if this is a software problem or hardware since the screen is perfectly fine when I have an overlay/filter app running in the background.
I have tried resetting the phone, installing a custom rom and disable hardware overlays etc but still no luck
