Nexus 4 image persistence? - Nexus 4 Q&A, Help & Troubleshooting

Alright, so I have a nexus 4. I don't know how long this issue has been around, since only now am I noticing it. After having a fairly high contrast image on the screen for a few seconds, such as the facebook status bar, if I go to another app or the homescreen, sometimes I can see a faint outline of the image. It can occasionally get really bad, especially after the screen has been off for a while. Like I was watching a video on firefox, so I switched to landscape mode. The video couldn't go full screen and I had two grey bars on the side. I was shocked to clearly see the firefox navbar burnt into my screen. Thankfully all of it cleared up, but I'm wondering if anyone else has an image persistence issue. I'll try and get a picture once I can find a camera with decent exposure. Also, it seems that the sides of the screen, especially the right side, are brighter than the rest of the screen, also after the screen has been off for a while. Don't know if the two issues are correlated or not, but I think they are. I was using facebook and my phone crashed with a white screen with lines going through it, awful image persistence, and terrible bleed through. Held down the power button and there was the bleed through and image persistence, along with screen flicker that makes a CRT look entirely static. I'm wondering, what the hell is up with my phone? I haven't really done anything wrong to it, this just kind of happened.

Got a photo. Couldn't find the cable to connect my camera to my computer, so I had to take a photo of a photo, and for that it turned out alright. Don't know how well it will turn out on different displays, but trust me it's there. This is the icon in the top right corner of the facebook application. When I swipe from the right to the left to see who's available for chat, I can see an outline of the icon that was there before.

I've noticed the persistence too at times, like a ghost image - CRT with a static image on too long, so if there was any doubt, it's not just you

I've had the same problem several times before. I just had it again, quite prominent! It stays for a few seconds, and then fades off to nothing.....Quite worried? :S

Visible dots grid in the screen when turned on (touch sensors)

Hi,
I wonder if anyone else has noticed this in the blackstone; I can see a grid of dots all over the screen when it's turned on. Ok, you have to look closely, but it's a bit annoying. I can see the dots better when I have a white or green background. For example, going to Start -> Programs I see the dots in the space between the icons.
I know the dots are from the 'resistive' layer, the dots are the sensors of the touchscreen... but they become visible and appear as small green dots perfectly aligned. I don't see them all the time, only when I have a white background or looking with a certain angle.
Should I be concerned? Could it be a problem with my screen?
Thanks!
Sounds a bit strange to me, the only time I can see the dots/grid is in bright sunlight. Then they look like small pin points in plastic.
i've never noticed that on mine...
That is normal, those are touch sensors for the screen. They allow the screen to recognise a touch.

Agree, but I had other PDAs before and never seen the dots when the screen is turned on. I don't care about the dots being visible when I'm under a bright light; my point is that I can see the dots when the screen is turned on, no matter under what kind of light. When I have a white backround, it looks like there's dust on the screen. If I look closely, I can see the dots in green colour, as a result of the reflectied light from the screen. I know they are the touch sensors, but it seems no one else can see them--
Any idea?
Thanks!
it is indeed normal especially under bright sunlight. However if you insist that you can see them when you switvh your device on, no matter the external light conditions, there might be something wrong with the screen. Have you seen other HD phones recently? Do you see the same dots there when they're switched on?

I haven't had the chance to see another HD; I've looked at a Diamond and Cruise, the dots are NOT there. I've tried to take a picture, but seems impossible to see the points in a picture (at least for the N95's camera).
I found an old tread talking about old PDAs that had the same issue, maybe they explain the issue better: http://forum.brighthand.com/showthread.php?t=207321
I'm not sure if I should send the HD to the service. Anyone knows how the 'worlwide warranty' works? I sent an email using htc.com site, but they don't respond.
Thanks!
Any advice on this matter...?
I don't know about colored dots, but every pocket pc I've ever owned had the dot grid visible in sunlight, it is normal, they should be clear dots though.

samsung vibrant pixel marks

There seems to be an issue with the super amoled screen. Its not a biggy as of yet. It seems if you have something on the screen for long periods of time it will wear the pixels out. My example....if you go on a white screen in landscape, the look where the status bar usually is (where it says samssamsun) you can see a fainted image of the status bar and a collage of times, battery and signal (i assume from always changing). U cant really see it and sometimes i wish i couldnt. Small flaws like this upset me. My phone isnt rooted (no screen shots) if you have a vibrant or galaxy s. Could you text and see if this is a product wide issue. Thank you for reading please leave comments.
Don't see that on my phone?
uhh, a screen shot wouldnt show burned out or worn out pixels dude.
So I ran the flashlight application, held up the screen, tried looking at different angles, and couldn't find one anomaly.
You should trade it in for a new one.
did the same thing with the flashlight app, nothing shows up. this dude is on crack.

Maybe he just has a lemon?
I can attest to this. I see it after just booting up and going from the lock screen to the desktop. I can see the faint outline of the white numbers from the time on the lockscreen on my GenieWidget on my desktop at the top of my homescreen(widget has grey background). It seems to dissappear though.
I have some when using color flashlight I see marks where the time is. It is very light but I see it. Tmobile is replacing it now. Lol

Call button images burned into the the screen?

Hi
not sure if anyone else has noticed this but it seems that the call end button, the button to view the dial pad and the button to view speaker options are burned into my screen!!! viewing in most apps it is not noticable but if you open internet explorer and go to a new page without loading a website the images of the buttons and very visiable in a brownish color I have had my focus since it was released in the US, I have also checked my wifes focus and it also has this burned into her screen.. Has anyone else noticed this?
Yes, I have the call tile, message tile, and the little circle/arrow burned into my screen. As you said, it's only visible on light colored screens, but it is visible. Unfortunately, unlike the temporary burn-in on new plasma tvs, this burn-in will not go away.
If you want to see something really bad, go up to the at&t store and check out the Focus that's on display. The Focus at my local at&t store looks horrible. I can't imagine anyone wanting to buy that phone if they saw that display model...
edit: by the way I love your weather app, I have had a few problems with it over the time i've used it, and you have always been fantastic with your support. Thanks!
Are you using blue tiles? I heard Blue OLEDs burn out faster than other colors and changed my tiles to green.
I have been using the brown almost exclusively; occasionally I'll go with blue, green, or lime, but the brown just looks the best to me.

thanks for the comment. on to your screen you have the actuall tiles burned into your screen? wow i only have the call end and function buttons burned i think its related to having my display on bright i took it off the automatic.
It's actually not the tile, it's the icon inside the tile that is burned in, but it's only visible on white screens. It's still quite annoying. As soon as the hd7s is out I'm going to compare screens, if the slcd is close to the samoled then i'm jumping ship I think...
and yeah my screen is on bright (not automatic) also. I think my problem is that I have the time out set to 5 minutes, and I never locked it myself

Based on HTC's latest track record with the Desire HD and Inspire 4G, make sure you analyze the viewing angle of the HD7-S. HTC has said it will have a Super LCD but, according to an answer they gave to a customer complaining it wasn't true S-LCD tech, the display will likely be what HTC is calling "Super" LCD...meaning it is their name for the super-sized display...and having nothing to do with true S-LCD tech.
If the viewing angle isn't as good as the iPhone 4 or Focus...or other SAMOLED/AMOLED equipped devices...then it isn't the higher-tech display but just an ordinary non-TFT LCD.
Super AMOLED is a great screen. But the pixel life span is still way short. The Blue pixels are the shortest. The old stats are 2000 to 4000 hours. New information point it around 10000 to 14000 hours. But Samsung didn't release any spec on this.
You should always keep the screen dim and keep it on as short as possible. Reportedly use a red theme will not only preserve blue pixels but also prolong battery life.
No burn in here. I have the phone set to turn off screen within 30 seconds, and have always used Lime colour tiles since it matches the Xbox Live tile.
Just a follow up on this issue, and possible a "what not to do" post. The burn in on my screen is getting worse. On a white screen, I can now see the phone icon, message icon, small circle/arrow, the word calender, and my google mail icon. I have the screen set to time out after 30 seconds, and I have the brightness set to high (not auto).

[Q] Brightness/Color reduction issues (NOT hardware problem)

The problem: Most screens on my Droid 2 are consistently darkened, as if dimmed to the lowest setting. The colors are even inverted in a few places. I would be inclined to call this a hardware problem, except that many of the stock android screens (app drawer, contacts, settings, etc) display perfectly. As you can see in the (poor quality, sorry) photos, the app drawer looks normal, but the second you switch back to the Home screen, everything visibly fades to a darker, slightly inverted color scheme. Pulling down the notification tray only makes the display darker, and it unquestionably inverts the colors, turning black-on-white text into white-on-black, the wifi indicator turns from blue to orange, and the battery indicator turns from green to blue and magenta.
I've reset the phone to factory, run the SBF through RSD Lite, and searched the Internet high and low for someone experiencing a similar problem. I finally resorted to taking it to Verizon, but (surprise, surprise) they couldn't figure it out, either.
There's been no water damage, and the phone seems to be in pristine condition. It works great in every other respect, but it's basically unusable if the screen doesn't show colors and brightness correctly. I love this phone and don't want to return it to the EBay seller I got it from, but I'm beginning to feel that I have no other choice.
Any help from the XDA gallery?
Well, it's a moot point now. I just returned the phone to the seller; should be getting a full refund.
I'll leave this up for the next guy with this problem. It won't offer much help, but at least he'll know he's not insane.

[Q] Background ghosting

I have had my nexus 7 for around 3 months now and have noticed that there appears to be a frozen image of the white elements of my home scree that are slightly but permanently visible. It is quite faint but I have noticed that things like the digital clock, and the white notifications are always visible. Sometimes even with the chrome Web browser get stuck being visible on the home scree. Is this a problem that others have and is there a way to fix this?
Thanks
does it appear while taking a screenshot? if not, its the pixels burnt into the display if you left the screen on the same picture for too long.
