Hey guys. Was out and about the other day and was using my phone and as I tilted the phone down out of the glare of the sun I noticed some weird vertical lines on my screen. Each evenly spaced same colour etc.
I can not replicate the effect unless there is large amounts of light or im outside in real light. BEAR IN MIND ITS ONLY VISIBLE AT CERTAIN ANGLES.
The lines don't appear on any pictures or hinder the video. They ar only visible during sunlight.
What im wondering has anybody else got this I will say issue. Or any insight as to what it could be? If there's a problem Carphone warehouse will want to repair it and not give me a swap for a new phone. What light does anyone have to share. Or am I just being paranoid?
My Titan is exactly the same, I think its just the way the screen works and is nothing to worry about.

I've got mine from Carphone warehouse. Haven't noticed this yet. They will replace it for you within 28 days. Else it goes to HTC for repairs. However, where did you find this sunlight? It's been so gloomy out here. BTW as mentioned above, this could be just the normal screen behaviour. The other two issues with screen that have come up so far are - the pink dot in the middle and grey keys visible on white background. Nothing back from HTC.
Hold your Titan with the screen directly facing you, at about 3/4 arms' length (as in, just sorta normally with your elbow bent a little) under diffuse light, with the phone powered up and the screen off.
Then tilt the phone backwards. As you get about 3/4 of the way back, you might see a regular pattern of thin stripes running up and and down on the screen.
They are not visible when the screen is powered up. I think it's just a normal part of the way the LCD panel works. As an analog, on my Dell Venue Pro, I could see a grid of dots under its AMOLED screen when looking closely at an oblique angle similar to as described above.
I also have a matte finish screen protector on my Titan, which might be making this more pronounced. In any case, it is absolutely *not* happening when the screen is powered up -- even in black areas of the screen.
Hmmm... Maybe it's a future charging grid.
have you guys noticed anything new in regard to htc amaze blue lines. i just go the phone a week ago and i have been noticying the same things. any new info thank.
My Titan also has these blue vertical lines, and it is seen only in daylight with screen off.
I see the same too but I thought it was from my screen protector...
I'v noticed a burn in signs somewhere in the middle of the screen (later I'll take a photo), its looks like a little shadow, darker...
Seen it only when I used RGB screens...
There is something to do (without replacing the screen)?
I'v heard about 2 options, donno how much its safe or will effect:
1. Using Jscreenfix - most for stuck pixels (its not the situation) but maybe it will do something after running few hours
2. Use blank white screen for few hours while the phone is on.
some says with full brightness, some says with low brightness, some says it will burn in the screen and will cause more damage....
Do you have any experiance with these 'methods' or any other tips to get it fix or halfix?
Thanks!
Are you using a non-oem battery? I order one from eBay (yes, I know ugh) and it was a snug fit and caused dark spots on the screen from the pressure.
Mine has a dark spot too, right in the middle of the screen. Looks almost like a shadow. I noticed it the first day I purchased the phone, within 2 minutes of first turning it on so its not burn-in. Its more noticeable for me on white screens like the google search page. I seem to recall one of the many cell phone models I've owned also having this problem. Maybe EVO?
Personally it doesn't bother me but I could see how it would drive others nuts.
I can personally vouch for the jscreenfix when you have issues with stuck pixels, however i dont think it will do anything for a burn in or dead pixel. I had a cluster of 4 or 5 pixels on an old blackberry of mine get stuck and played that jscreenfix for hour or two and it brought them back. But like I said I don't see that helping with a burn in though, if that is your issue.
Here's a picture of this burn-in, bad quality but can't miss the 'shadow' ...
@jrebo - I'm using the original motorola's battery.
Any chance it will 'fix itself' or there is nothing to do?
What about the option of using a white blank screen on with low/high brightness ? will it make it worst or its possible help?
Thanks!
I have a white spot in the middle of my screen and I've been using the oem battery.

Why these dark spots / clouds appears anyway?
Seems like its happening at lots of smartphones...
I have a Nexus One which have a top notification/status bar burn in - maybe because it was on the stock rom with the white bg and set to be shown all the time.
But here its looks different, as you mention - cloud / smoke / dark spots...
Still not sure if keeping the phone on with full white BG will do the job or will **** it up more.... also not sure what brightness should use with this white bg...high or low...
@jrebo - about the replacement battery you bought, after how much time using this non-oem battery you've notice these dark spots ?
I'm considering to buy another battery from ebay (there is no other place here to buy oem batteries for photon) seems like there are some 'OEM' batteris (HF5X) out there with tag price of ~10$, not sure if its real or knockoff and what problem could it cause...
screen burn in can not occure on lcd and plasma displays since there is no phosphorous layer that the colors are being shot through... however there is something similar but its not permanent... pixels of other colors are not releasing there charge so they end up not going back to their neutral state. To cure this issue you get any one of the apps out there that run your screen through random colors every so often or leave the phone off and with no battery for a few days that will get rid of the immage permanence that you see. if that area on your screen is showing a cloud that does not match your current wallpaper than there is some other issue going on. and to cure that i have no clue lol
Good afternoon,
About a month, stripes appear on the screen of my phone. I didn't dropped it, the stripes just appeared of nowhere. The screen has no scratch or scrape.
Can anyone tell me what's the problem or what replacement parts should I buy? (In a authorized store they give me a 295 euros budget... too much for me ).
I'll leave some pictures. Thank you!
I love my Xperia Z4 Tablet. However the backlight is noticeably dim on the bottom (when in the default landscape position) or the left hand side when in portrait (volume/power button facing up). It is most noticeable in portrait mode when there is a white background (Kindle, Chrome and Instagram most notably). I am willing to live with this issue, but was wondering if anyone else is seeing any issues?
For the price I paid, it would be nice to have uniform backlighting. But I am worried it could be worse on another unit. Expansys has offered me an exchange or refund but there is a delay in availability now that the first lot has sold out.
No problems with mine
I am sending mine back for an exchange. I miss it already
Now I noticed that too. The difference is really small, but it's there.

Hopefully my replacement isn't any worse than the one I just sent back. It was as bad as I could handle.
Interesting, the same with my tablet - seems to be a general problem
I don't know if I should return and change the tablet...
can you make a picture for us? I dont know what you mean? my backlight is perfect - no bleeding and no clouding )
I'm sorry, but it was not possible to make a picture where you can see this.
However I can only see it on white backgrounds - the first centimeter is slightly grayish...

It is not a hardware problem. I see the band only when the bottom menu appears. It looks like the transperancy issue with that menu layer.
Mine looks fine, just hope it is not something my eyes just don't notice, but others do.

No, I think it is a hardware problem - if I turn the tablet from landscape to portrait mode, white backgrounds are gray on the left. Btw for me it's only visible in portrait mode - in landscape mode the menu bar on the bottom is usually black or transparent...
It is definitely a hardware problem and it sounds like the backlight is weaker on several units on the bottom (when in landscape) or left hand side (when in portrait with power button facing up). It is a shame as it is very distracting to read on anything that doesn't have a dark or black background in portrait. Still waiting for my replacement unit As long as the replacement isn't worse, I will likely live with it as I really enjoyed (and miss) the tablet.

Try anything with an all white background. If you open Chrome with no web pages loaded and the new tab page up or Kindle with a white background and hold the tablet in portrait, you might see uneven backlighting on your left or right sides depending on the orientation.
Backlight direction is notable
Got my Z4 tablet yesterday. After reading some issues with the backlight I checked this at my device and can see there is a notable uniformity.
If you hold the device with power button upside, then one can see a thin bright line from the backlight LEDs on the left side, while the opposite screen edge is slightly darker.
It looks like the screen is only backlighted from one side. For the normal usage it is not really annoying, but it is there and you would see it, if you take attention for the issue.
Do other Z4 owners have the same effect?

I have the impression my Amazon Z4T packages was already a replacement from someone else. The box made used look, some scratches and one corner had a ditch.
It wasn't sealed in any way. The charge adapter cable looked out of its the small box. The screen protection layer made the impression it was reattached, a lot of air bubbles were included.
Can someone describe how he found the delivery when unboxing it?
Was it sealed?
I also consider a replacement, if the screen issue is not a general construction feature.
Oddly enough, I purchased mine from another supplier, and also felt the item had been handled if not used. USB cable was out of wrapping and screen protector had signs of being removed and re-applied. I received mine the day after they were available for sale. I am hoping my replacement looks like new and has minimal or no backlight uniformity issues.

Hopefully you get it soon and can report here the condition of the replacement.
I have 14 days left to send it back to Amazon for free.
Please also describe how it was packaged.
Are there any seals or blister foil?
I can't believe Sony delivers an open package to retail stores.
Unboxing videos on Youtube don't show this clearly.
Thanks in advance.

For me:
Not sealed.
Box in perfect condition.
Screen protector had a few bubbles, but not that many.
It was perfectly even on the tablet, edges protector = edges tablet.
Charge cable was in box, but it was wound a bit loopsided. But I think it more likely that it came that way - besides, how many people do even need those cables nowadays? Even if they need them, they likely will not use them when trying the tablet out.
Charge of 65%
Tablet itself:
I couldn't see a backlight uniformity issue, tried it with a white background with 100% luminosity in a dark room. Compared to the Z1 Tablet the screen looks a LOT dimmer in the dark, but I suspect that is more because the Z4 has some auto-dim function there. In bright light the Z4 screen looks slightly brighter.
What I noticed is that the speakers produce a fair amount of white noise. At 10% it is very noticeable, at 50% I do not hear it unless it is a very silent scene and I am concentrating on it. Somewhat annoying and IMO not something a tablet in that price range should have, but not annoying enough for me to play replacement bingo.
My seller is out of stock with a new batch due next week. I'll let you know when it comes. From what I can tell, Sony products are never fully sealed.
Hello XDA !
I just bought an Honor 10 128Go Phantom Blue 15 days ago. I was pretty happy with the device until I notice some backlight bleeding in the bottom and a sort of shadow around the notch. I returned it to the shop and they exchanged it with a brand new one.
But.... The new has the same problem. When looking at white backgrounds, worse with grey backgrounds, there is a noticable difference in backlight betwen the bottom, sides and top of the phone and the middle.
Did any of you noticed the problem ? I'm trying to get a refund but the shop tells me there is no problem on this device, nor on the previous. Why i didn't buy it on internet...
Thanks !
