stuck red pixel

Hi all, desire arrived yesterday and is fab. Only problemso far is that I have a red dot/pixel on the screen which is to the right of the 8 when I have the keyboard up. Tried 2 apps from market place to get rid but one comment said it wouldn't work on led screens - and it hasn't.
Is there anything I can do?

Ok so having done a bit of research whilst watching the GP, it appears that not a lot can be done. It's so small, only seen on light coloured backgrounds, that I might leave it. Will see if T-mobile want to swop though just in case

ring t-mobile they should give send you a new one in replacement

Yep, you should phone T-Mobile and ask for a replacement!

Hello.... T-Mobile?
I have a duff HTC desire... stuck pixles, etc...
Oh... you don't have any? when will you be getting more... HOW LONG???!!!!??? :-(

Sprint L710 Galaxy s3

Something i noticed when setting my wallpaper, I have always used a black wallpaper since i had the Galaxy s2 and Galaxy Nexus to "Save battery" but I went to set one on the s3 and notice on the bottom of the screen it appears to have a "scratch" buit it only appears when using a black background.
I have ran the LCD test *#0*# and it does not appear on any other color other than black... is this a common issue or should i attempt to get it replaced?

Anyone else with this? It is almost like a DARK STREAK that stands out...Im kinda of OCD when is comes to things like this, is this something i could take it back for? and if so do i just let them know my screen has a dark spot?

LCD test isn't working for me on my GS3. You sure it's *#0*#?
EDIT: Downloaded LCD test and on black screen, it is completely black (like the screen is off), which is what it's supposed to look like. You might have dead pixels or something?

OP you're not crazy. I read about that somewhere. **edit** found it. Is this what you're talking about? http://forum.xda-developers.com/showthread.php?t=1715936

Would dead pixels show every other color fine?

Yes this is something you can exchange it for technically.

Ok im trying to recreate the problem but just like the link said Im not able to get the "darker" pixels to show in rooms with light...
What would I say when I get to best buy?

Tell them the truth. If they say "no" then ask for a manager. If the manager says "no" then ask to speak to the district manager. Just don't be mean about it and they should be able to help you. They most likely won't doubt you as they won't be able to test it since those damn stores are so bright. It'll just be easier for them to exchange it.

+1 or have one of their techs take it to the bathroom and turn off the lights.

I'm on my phone so I'm not up to digging up the links, but this has been discussed several times, both here and in the international version forums. They're usually referred to as "ink marks" and from what little I've read, they're on every single gsiii, and maybe even some other amoled devices including older galaxy S's.
I love my screen. However just last night I was curious so I installed the dead pixel test app from the market. In a dark room, on the black screen in that app, if you get your eyes focusing just right, you can see some black-er spots. It really doesn't bother me though, because I never notice them during normal usage.
I'm not saying to just ignore what you feel is a problem, but beware your replacement may have similar markings.

Why does the title of this thread have Sprint in it? carrier is irrelevant for this question.

I played this "game" a few weeks ago. I also live outside the US, so I had to send it back for repair,due to a speaker problem (the speaker was 'crackling') and no firm in europe could fix it.. They were the worst weeks of my summer,it took almost 2 months to get my phone back,but I dont have any issues with the phone since then. Hope youll have more luck, 2 months were really too much.

I'm seeing something similar but It's not always there, only shows up occasionally when the screen goes off and I wake it, started happening using liteROM

It's not a "stuck pixel". AMOLEDs can have dead pixels at worst (and it's MUCH rarer than in LCDs and usually it's only one color that doesn't respond). There's some deeper issue. Take a screenshot and see if it shows up there -- that'll tell us if it's in software or hardware.

It is a screen burn ,i have tried to solve problem with Screen Burn-in Tool app from Play Store
but no success,this problem have also few my friends with lg g4,i newer buy any lg phone again, lg is better to produce tv sets and wasmachines because as phone manufactures sucks.

Same issue here too, it isn't necessarily burn in, more image retention I guess which tends to happen to some LCD's, tried all sorts of things to fix it, if anyone knows how to fix this that would be awesome
Guess we'll have to either get the device replaced or replace the LCD

If it's retention the LCD won't have to be replaced. Just wait a little, and it's gone.

And it inst always there, it knows to disaper.
And one more thing, it constantly changin, for example now i see 12:30, and for 2 minutes i will see 12:32, not one picture burned in.
Sorry for my English, i hop you will understand what i trying to say.

Its pretty bad retention if thats the case, not permanent...only really see it on grayish backgrounds....Ive left the phone off for days...switched it back on and within a matter of minutes my status bar is burned in lol

Same problem here pink burn that appears only on gray with a few minutes of use.
I was wondering if its just my device or not.
And now that i know that is the case i guess switching the phone display will not solve it.

I am getting this issue as well. Pinkish tint (when there is a light grey background) and image retention on the top of the screen and I can see those little icons. Did you get the problem after motherboard replacement due to bootloop issue? I am regretting my decision in purchasing LG G4.. :crying:

It is the display, friend of mine replaced his and he no longer had this issue.
I think he ordered a $70 USD replacement off Amazon and did it himself since LG requested for him to send the phone to Taiwan.

To be honest it does not really bother me,the only thing is that i can not put a gray wallpaper :/.
And when you mention this i think it actually started only after i got my motherboard replaced because of the bootloop but i might just did not notice until than..
And no regreting is needed alot of people that i know with s6 are not so happy about it..and the only other option was m9...so.....if you like me and had no choice the g4 was the smartest choice lol and i am quite happy with it...

Well i was talking about that, if you would give your phone to lg they will replace with the same display..so i dont see the point...
And the replacement displays you cant tell how are they as in brightness battery drain and color accuracy...
I guess if it will get worse than i will probably replace it..for now its fine enough lol

Meh...it's really not a huge problem lol, it grew on me after some time and it doesn't bother me anymore
Hasn't gotten worse over the past 6-ish months or so, so I guess it'll stay this way
I'm from Jamaica so sending it to Taiwan is going to be a bit of a problem
But as for the replacement part, I definitely get what you're saying, I asked my friend about his for the purpose of this thread and he told me that the battery life is the same, brightness/quality is similar to the original display, worse case scenario if you need to change the screen I'd say go for it.

I have found a some kind temporary workaround ( i don't know is that correct language expression in english so sorry for that )
Mainly here is what I did : I have flash latest SUPERXE kernel for stock rom android 6.0 from here , after flash from Play Store I have installed app Kernel Adiutor ,from the drop-down menu selected Screen section and aply this settings :
RED=230
GREEN=235
BLUE=235
Minimum RGB Value=35
Saturation Intensity= 30
Screen Hue=0
Screen Value= 125
Screen Contrast=127
After this no more red colored retention on gray background,not even in TWRP recovery.
This solution is only for rooted devices with unlocked bootloader,I hope this will help You
After kernel installation i have run few times antutu benchmark,so maybe this is also have influence on screen refresh.

This worked for me, too Thanks for sharing.
Anyway I will try warranty soon.

Dear guys, 12/2015 I have same issue that burning, my local warranty service ok change a new LCD, it is very OK after replacement, no burn any more. But after 6 months the same issue come back, it is hardware issue. LG always have issue about hardware in flagship more than other competitor.

Not a G4 owner but I have used a G4 before as well as a V10 and a G5, currently own the V10. This issue is present on all three devices and isn't a question of if it will happen, it's a matter of when it will happen. I noticed this issue with my display a few months ago and the entire affected area has a weird yellowish hue to it which is most noticeable on a lighter grey hue and as of now have grown used to it to a degree: still annoys me a bit. Also had a friend whom I recommended the G4 to and he had this issue with retention since he got it though he barely notices it since his phone is almost always set at 0% brightness
Anyways, at this point the main cause for this as I've said in a couple of threads is the display technology itself. I'm guessing this is one of the side effects Quantum Display has for offering near-amoled quality with vivid colors and blacks in comparison to regular LCD panels. Basically, even replacing the display is a temporary issue and still a lottery as you may get one with no issues until a year later or one that already has retention out of the box.
At this point, I might even tolerate amoled displays or non-Quantum Display lcd panels but it's too bad LG makes great phones. Oh well, just another thing to keep in mind when getting a phone from LG

I started getting this burn in and i am 95% sure that it didn't happen before. My G4 was in bootloop so i sent it back and i think that they replaced motherboard. After about 2 months of usage i started noticing this and as i said i am 95% sure that it didn't happen before motherboard was replaced, only if i didn't realise that but i am sure there was not this problem. :/ :/ :/ Is it actually possible that it is coz of motherboard replacement and that it can't be fixed even if i replace screen?!?! ((

It's not a motherboard issue but a display issue. With the G4, V10, and G5, there will be displays that will have retention out of the box or in a matter of a few months and then those who don't get it until 2 years into use or in fact, never at all. Only solution is replacing the display but that's a bit of a lottery in it of itself as you don't know if it won't have its own issues and I'd imagine constantly buying new LCD digitizers to grow costly that you might as well just buy a new phone altogether.

New HTC 10 Owner looking for issues

Hello HTC fans,
I am gonna receive my HTC 10 tomorrow and I would like to immediately look for HW failures/defects, etc. to see if I have a faulty device.
My Question is., what should I check?
- dead pixels
- Speaker issues (I dont know what to check exactly)
- Microphone issues ( how to test?
- What else?
Can you please help me out?
Thanks in advance

Take it out of the box, put it on the charger. Make sure it charges to 100 percent, then use it.

That was quite obvious, I just thought there are "bad-batches" but if theres nothing like that (like it was with the m7 series) I am not worried

Get it out of the box, look if your display has a red tint, if it has a red tint install Dev Check and look which display is build in (Sharp or Tianma). If it is a Sharp display and hast red tint return it, if it's a Tianma display the red tint seems to go away after some days/weeks of usage.

Exactly no reason to worry about maybe having a bad unit before you even get it. Yes there will be a bad phone here and there. Be more excited you are getting a new phone!

The first thing to do is run the diagnostics. To do this, run the Help app. On the Help screen menu tap 'Troubleshooting' or 'Diagnostics tools' to use a troubleshooting wizard to check the basic hardware functions (alternatively, dial *#*#3424#*#*).

I found red tint on my phone at the bottom of my screen which didn't disappear after 3 weeks. In the end i got rid my phone as that tint was doing my head in.

Yes had that option but I chose not to replace it as I prefer bigger screen. I thought I could live with smaller screen but clearly not. If it was 5.5 then I would have stuck with it definitely.

Well, its all personal preference .... for me the 5.7 XL was way too big (I have big fingers too...I am 198CM ) and the HTC 10 is just an upgraded m7 for me hence the love

Personally, I'd rather just return it and get a new one if it's within the first 30 days. Seems like more of a hassle to get repaired or possibly sent a refurb in exchange.
