so it is not limited to stock ROM. i think it is safe to replace my display before warranty period ends. but real question is why it is happening??

[Q] Found dead/faulty pixel on screen of sk17a

So I noticed a dead/faulty pixel on my sony Erricsson Xperia mini pro sk17a night. On the most bottom, right part of the screen of you look at it portrait. This pixel flashes whenever I scroll down webpages nut flickers often even on the home screen. Either that or its really dim. It's just one pix I think.
So is anyone else getting this or just me?
Also, to fix this I go to my phone service provider to get it fixed right? Since its Rogers and it said they will fix it for free or something. I have not rooted or done anything to void the warranty.
Exactly the same problem.
I have exactly the same problem on SonyEricsson sk17a . Did they fixed it ?
There's a screen test on service menu: dial *#*#SERVICE#*#*, go to Service tests and test Display. It will go to a color every time you touch the screen, press back to exit. There you can see if its a pixel problem and wich color the pixel is stuck in (or dead).
Then you can take it to SE for repair (warranty of course).

Yes I would do the same.
10x.I'l give it a try.
I also contacted with SE's support. Just waiting for there reply ( to be honest it looks like a software issue ) . When there is static image on the display , it is OK.
Hello guys,
So what happened finally with that issue? Was it software problem finally? I have the xperia Mini ST15i and there is a dark pixel on the very left of the screen and it's only visible when there is motion, but not in static images of any color!
Please tell me what happened with your case.
Thanks!

Make a test in service menu as said some posts above.
If pixel is indeed buggy, take your phone to shop, should fall under warranty.
Its the screen's issue. If im not mistaken companies keep the 5 dead pixel policy. Not subpixel, but pixel.
If a subpixel is faulty (i think) you cannot see one of the three RGB subpixels, If the whole pixel is faulty you get a white dot where the pixel should be. So from what i understand you have a faulty subpixel, therefore the company itself wont hold it under warranty but your Service Provider might.
Pixel problem .
From the support center here in bulgariq , they told me , that they will forward this issue to SE .
No response till now . My problem was ( and still is ) identical . Pixel is OK on all the colors, except when there is moving image ( than it is not , white , gray or some other color .Than the pixell i just black (dead) )

I think I have the same issue, my pixel is ok in all colors, but when there is moving image (for example scrolling in browser) even in white color, there is a dark dot flashing.. when the scrolling stops the dot dissapears too!
Is it the same as yours?
dead pixel
Exactly the same behavior.
Same here... A pixel in the bottom of the screen, it works good, but when I scroll, the pixel turns black :S should I send it for the warranty?

Dead pixel issue
Try to send it . I wil contact them again and will try to point the problem more precisely. It is strange. It is not dead subpixel because it shows all the collors correct. I think the display controller is not OK. not the display itself.
so do you think that is the display driver? Or perhaps the build 0.62? Do you think that's good idea to return to a previous build? Is it possible to fix the issue?
I mean it could be graphics driver software issue as well.

Androids do not have such problems. At least never happened any problems with graphic drivers.

I mean its not the screen for sure because this flickering pixel is only obvious in scolling for example.. also its located on the very bottom of the screen. its close to the XPERIA logo and light on the right. if the refresh rate is high it flickers fast so its difficult to see it.. when its static image there it dissapears..
Ofcourse it is an issue of the screen... You have a faulty subpixel. Maybe on non scrolling occurences the color is stabilized with the remaining 2 . This isnt windows/linux/mac, you dont upgrade drivers as you would on a computer. And no its not your GPU. If it were the gpu it youd be going haywire in random parts of the screen not just a specific 1x1 pixel area

To be honest I don't know if its a subpixel thing.. For example when Safari is loading, even on a white page, this pixel is flickering. When it stops loading the page, the pixel dissapears..
Have the same issue with my Xperia Mini ST15, I have a stuck pixel in the middle of screen (yes... that sucks) but it's only visible when the screen is showing a black color, its a shine pixel.

Screen flickering issue?

My friend has a desire x and has the screen flickering issue. Is this software related? should she update her desire x ?
Always better to check with service center...
Settings, development options, turn off strict mode and show screen updates...

I had similar problem with the screen that when I touched anywhere on the screen a shadow appeared on the center of screen similar when someone press a TFT LCD screen with a finger.
I have returned it back and got a new one without similar problem.
Although I have seen the same problem (but with the shadow at one of the edges) on a demo DX device.
Hi or so that you have the DX screen by pressing a finger to the screen as he swam like a laptop screen ??????
I have another flickering issue...
I've never mentioned anything wrong when touching the screen, but I've noticed that when the brightness is at low levels, the screen will flicker (like that) if the background is set at (light) dark colors.
I had never seen this happening with any of previous smartphones, so I'm gonna sent it back to htc (for this and the hiss issue) after finishing my exams and I'll report back.
Exactly, but I had this in the middle of the screen not matter where I pressed on the screen. And it was of course more obvious on dark or grey backgrounds.

[Q] Black shows as red. Colors compromised on I9305?

Hello.
I've been using my I9305 a while now with a 4.4 OMNIROM.
Everything was fine until I let my girlfriend borrow it to use the gps for a trip.
She returned it and I noticed the colors are strange. All the blacks went greyish, and gradient colors werent smooth but showed artifacts.
I thought it was a setting but after factory resetting/wiping everything/changing rom the phone still has strange colors, even the green boot android icon seems abit light.
Here are some screenshots showing the same pictures on my phone (the samsung) and a functional HTC. You can see the artifacts and the distorted blacks.
Code:

[img]imgur.com/sAIiDnB.jpg[/img]
Is it possible she dropped it and damaged the screen/matrix?
Is it possible that some connector to the lcd/digitizer got slightly disconnected? (maybe i should try disassambling)
She used several apps (tomtom, navigon) that have nightmode (screen altering modes), maybe its stuck or damaged.
Please help

Seems like a hardware problem to me. I would try and watch lcd replacement videos to see if the screen is correctly plugged to the motherboard.

WTF??? Screen burn in??

I was trying out a compass app on my LGV10. The app has white lettering, etc and a black back ground. The phone needed to be charged so I just plugged it in and set it down. I didn't pick it up again till the morning. I killed the app and then noticed very lightly I could still see the image. You you can see a very,very faint image of the compass app. I tried turning it off for a couple hrs but it is still there.
I"ve never heard of LCD screen burn in; but there it is.
Anyone dealt with this before??

yes, with time the screen get "ghost images" but they dissapear if you turn off the screen for 5/10 minuts. Mine is getting that kind of "ghost images" from apps i opened and mine is on the sides they get a yellowish tint in both sides and some in the top of screen, nothing to be scared of...isnt burn in...but overheating of the screen.
Use BLUE LIGHT FILTER app (on play store has icon with a phone with blue screen) and set "filter opacity 15%" and "screen dimmer 50%" on color BLACK. I read that in 3d v10 of my model (h962) and ghost images never happen again with min o max brightness in every use.

Reply; thanks for the info guys.
Day 2 and I cannot see the latent image from the compass app anymore.
Not exploring the woods or anything, but I need to install a TV antenna on the house and have to aim it dead on 115* from true north.
That you cannot truly ascertain without a compass. From standing in my yard, what seemed like true north to me was actually NNE.

Wow that worked. Thank you. The trick seems to be to use black color. Been trying with red filters but did not work. I only need to set black filter to 5% only and all ghosting is gone. This keeps brightness high. I had some pretty horrible yellow permanent ghosting on edges of screen that appeared very fast. Now not at all.

I will have to try this. I cracked my screen on my V10 and picked up a bootloop one on eBay that still had a perfect screen. Did the swap of my motherboard to the new screen housing. All went fine except I noticed excessive ghosting on the bootlooped display.

Please report back if it works for you too.
I used this app: https://play.google.com/store/apps/details?id=jp.ne.hardyinfinity.bluelightfilter.free
All my screen needs is a black filter set to 3% (might even less, have not tried lower) opacity and I never see the heavy yellow ghosting that came after minutes on edges and top of screen before in the same places. As a result my whole display is now cooler and cleaner most of the time because the ghosting was pretty severe when the phone was used for a while.

Pixel flicker when turning on screen ? Video Below. Return?

Wondering if any of you have a flickering of your screen when you press the power button or turn on the device. I notice in the top left of the device some pixels light up before an image is shown when turning on the screen. I'm still within the return window so I wouldn't want the device to have display issues down the line.

I have the S1 and have never see one part of the display light up before the rest, have you tested the screen,
Download a screen test app and go though the colors in a dark room, you can normally increase/decrease the brightness just by dragging your finger up and down the screen, check for any inconsistencies in the screen, a low brightness light gray shows up a lot of problems.

I returned that unit to Costco and bought another. Didn't want to risk it going bad later.
