What kind of dead (or stuck) subpixel is this?

I have an odd pixel right in the middle of the screen. When I run Dead Pixel Detect (which you can find in the Market), it is lit in the following ways:
- on a white screen, it seems red;
- on black, it seems black;
- on blue, it seems blue;
- on red, it seems red;
- on green, it seems black;
- on yellow, it seems red;
- on cyan, it seems black;
- on magenta, it seems magenta.
Does anyone know what kind of faulty subpixel(s) this is about? Is it a dead green subpixel?

I think it's just a stuck pixel because if it was black all the time, then it would be a dead pixel. Try JScreenFix from the Marketplace and pray that fixes it:

Well, I'm sure that it isn't a dead pixel indeed but it seems to be a dead subpixel. :-( I already tried that JScreenFix app but it hasn't made any difference so far.

Technically, I think it may not possible for an AMOLED to get a "stuck pixel" like you would get on a normal LCD screen. The fact that you are getting a red pixel on a white screen, most likely means that the G & B (as in R,G,B) are dead.
Traditional LCD screens produce different colours by passing a charge through a kind of lens that twists producing different colours as the light passes through it. A stuck pixel happens when one of these lenes gets jammed and stops twisting, which is why you can sometimes fix them by flashing loads of colours on the screen rapidly, it sort of rattles the pixel loose.
If you've got a pixel that's displaying the wrong colour then it's broken rather than stuck.
I am not sure what else you could try to fix this... is it still under warranty? Realistically, I think having it replaced is your only option.

I have exactly the same problem a 'pink' pixel on the screen which is mostly visible on light backgrounds. Did anyone try to exchange it for this reason? I bought it from t-mobile UK.
I know that in the past they would need a certain number of pixels to be faulty before they would change anything (tv-s, monitors, etc.) Is this true for this phone?

If they dont then just say it has a different problem, most operators send out the replacement and pick up the 'faulty' one at the same time.

Thanks for the explanation!
Well, I bought it 5 weeks ago so it should be under warranty although it is rooted. I can hardly see the dead subpixel (even though it is in the middle) so I'm not really concerned but I might consider contacting HTC customer service anyway.

No problem bud, although, if i were in your shoes, then i would unroot it and send it back for replacemet while still under warranty. Afterall, you paid for a product that should not have any defects, and something like a dead pixel to the screen would annoy the hell out of me

Yep, I'll probably do so. The only thing is ... my Desire was Vodafone UK branded, and I unbranded it when rooting. However, there is no full RUU available for Vodafone UK handsets. However, in my opinion, HTC should not care about that since it's a hardware defect ... but no one seems to know their opinion about it.

[Q] Used Nexus 7 - Need Advice on what to check before purchase

Hi,
I'm leaning towards buying a used 2013 Nexus 7 and have been reading about screen issues on this board. It will be a face to face purchase. However, reading all the posts about screen issues has me concerned.
What are the main issues I should check for besides the reported multi touch issue? Do current owners have any tips or advice on tests I can run on the device before I purchase it for known issues?
Thanks,
Rick

The screen and the random reboot issues are the main ones. GPS unreliability was fixed in a software update.
Some rarer problems are nfc not working, wireless charging not working, stuck/dead pixel, pinkish tinge whites, mushy power/vol buttons, screen separating from case (on the side), creaking case, cameras with poor dark performance, buzzing charger unit, backlight bleed, and probably others I forgot.
Honestly, unless you are getting a really good deal, I would just buy it from a retailer with a return policy. There are units that work fine, but it is hard to tell with the time alloted for a face-to-face exchange.

Thank you for the reply. That is a quite a list. I would buy a used one for $150 (16gb wifi). What do you think?

suddenly right button light leaking to screen[pictures] UPS on its way(RMA) opinions?

For some reason the softkey light of the right button is leaking to the screen.
When i lowered my screen brightnes ive noticed there is a light shining from the right softkey in to the screen. Its leaking trough a tiny hole between the glass and the amoled screen. I guess its an adhesive failure. I can see it when i use my phone with lowbrightness while watching dark content.
My questions
1. Can i fix this my self?
2. How is this even possible when ive newer opened the device?
3. could i fix it by pressing on that place and maybe also heating it slightly the same time?
4. is it possible that also dust will enter trough that hole?
5. would oneplus take care of that?

I'll only answer question 5 as it makes others irrelevant: yes, they would (they have to) take care of this. That's what warranty exists for. It's faulty hardware and it should be fixed or replaced.

No, they will fix the button backlight.
Also, you can turn off button backlight in settings.

Ive started a RMA request. Basicly its not a delabreaker for me at all because i never use buttonbacklight but im afraid dust might enter the screen and the gap could get bigger over time.

Ive updated the op and added some pictures. What do you think. Should i be worried?

I've reverted to all Stock including locked Bootloader and correct imei number. Ups will arrive tomorrow between 4&7 o clock (evening).
Im really scared they might not find the issue as it is very hard to find. How should I explain it for them to understand. Anyone knows where the devices are getting repaired?
Thanks

I canceled the rma process because they want to let arvato bertelsmann take care of it. And the things ive heard about them just schocked me. I will simply turn off softkeylights permanently.

if you are in the 15 days window please, return the phone, this phone is just a mess, it's a beast, but it seems like every device has a problem somewhere... mine has a pink tint on the upper part of the screen, i can't be hassled with the process of 1month or even more of a RMA just to repair or for them to send me a new one, i wen't ahead and asked for a refund instead, too much hassle with the support from op..

Its an adhesive error inside the device it should not affect dust coming in.
Given that oneplus support appears to be some sort of Asian Russian roulette you should not risk your, I hope otherwise flawless, device because of such a minor optical glitch.
@xAD3r1ty
The phone is not a mess, there may be some faulty units floating out there, but many are just fine.
Mine does not have any HW issues as far as I can tell.
Also there is no phone out there that would be a viable competition that is unless you have a donkey that sh!7s money

Don't get me wrong, i love the OP3, But it seems that too many people are receiving the device with a problem here and there
Because if you receive a op3 with a pink tint like a lot, and i mean a lot of people do, Then you will have to deal with the horrible support, deal with RMA's that can take 1 month or even more and get pissed big time for being with no phone in the mean time, Oh, and i've heard some nice stories about their repair center (Arvato), so yeah like i said and giving the OP an advice, i would rather return the device if still on 15 days period and just get a different device or even buy the op3 again than dealing with their repairing support.
Thats just it

screen cloudy areas issue help

Hi I am thinking of buying a phone on ebay and the phone only has this issue
http://imgur.com/a/2VUVL
what do you think it could be?
here what he seller wrote
" I noticed some discolouration in some areas of the screen. Upon investigation it seems there a few 'cloudy areas' that appear blue on an illuminated dark background, this is certainly when it is most noticeable (see pictures). Hopefully you can see from the other pictures it is not that noticeable under normal use"
any idea?

It's pretty noticeable in that shot. Good on the seller for the full disclosure, but I wouldn't risk it.

So should i go for this or not? I am still the winning bidder. I also so some screen broken phones thats i might consider to fix this as its the best option for me. I have about £100 to spend on phone.

If you're looking for a phone to repair, pick according to your comfort level. I wouldn't do it myself, but that's me.

Firstly, the crack in the lens. Each camera is fine tuned to the tolerances in the lens. Basically they are married at the factory. You will be lucky if you can get the blur out.
The screen might be replaceable and the battery may be goosed but the chances of the board being blown from water damage is very high because of the "cloudiness" in the screen.
I'd say you're about to buy a lemon.

Ho thank you for the feed back. I cancel my bid for the item then but their are some good deals on eBay. Some phones only have the screen cracked and to fix it its not that hard.

How to tell if your G8 is brand new or refurbished?

Just bought an LG G8 off Ebay. Seller sold it as new and unused and had a 100% positive rating. The phone looks and feels new - no scratches on the body, works really fast. Except for this:
https://preview.redd.it/smamclrvzo191.jpg
Personally, I've never seen such a thing on a phone screen before. Has anyone else experienced it on their G8?
Meanwhile, in the phone's hidden menu the battery cycle count shows 0 cycles so far and the battery health is rated 'good'. Not sure if these stats can be somehow reset and/or edited in any way. I also managed to register my G8 purchase on the LG Canada website using the phone's serial number without any issues.
Therefore - how can you tell if you're really getting a brand new phone, or a refurbished/renewed one? Among other things, my biggest concern is water resistance - as far as I know, refurbished phones are no longer water-resistant. And I had to get rid of my old HTC U11 exactly because of excessive water damage that messed up the screen.

Image forbidden.
The OS version should correspond to its manufactured date.
Never assume any "waterproof" phone is waterproof... a lot of people with destroyed phones who did.

Sorry, there you go.
P.S. If a phone gets a factory reset, wouldn't that rollback the OS to its original factory state/date as well?

No, a factory reset only erase the data on the user data partition. All upgrades stay intact.
In settings, phone, software information will give the firmware build dates. Not sure how LG handles that though.
Run Screen Test on it, and see how the display looks.

Ran the Screen Test app, swiped across the various colors and patterns and didn't notice any other screen issues, apart from the one near the notch. For some reason, the app blacks out the notch area and the greenish spot is barely visible at all, but you could still see its bottom side on almost every color, if you know where to look. Don't have another device lying around at the moment to take a photo, unfortunately.
Other than that, the software is Android 9 with Android security patch level March 1, 2019. The original box in which the phone came with says "Manufactured: 03/2019". IMEI written on the box and in the phone's settings is also a match. The only box issue was the broken seal.

It sounds to me like the original owner saw that pixel issue and decided not to keep it. Unfortunately, devices like this do get sold as 'new', or 'open box' or etc etc.
It's very difficult now to buy a phone with all of the shenanigans going on. Phones are so expensive you'll clearly find some unscrupulous people doing business. I doubt the phone has been refurbished though. Even a refurb from the mfg isn't going to 'reset' everything to zero to make it look new. That would be illegal.
Maybe contact the mfg to see if they can do anything about the screen issue. Are returns allowed on the device? I'd consider that also as the screen issue might be something I'd constantly be noticing, but maybe not for you? Personal decision there.

Personally, I prefer the blacked out notch visually - I even blacked it out when setting up the phone and noticed the spot a little after. The issue is that I don't seem to be able to remove the notch with all apps - Facebook and Chrome, for example, still whiten out the area around the notch and the spot becomes visible. I'm still on Android 9 though, so this could potentially be fixed in future upgrades. You would probably know better if that is the case.
About the returns thing - return for technical defects seem to be always allowed on eBay. Also, I've paid through PayPal and there's some buyer protection there as well, as far as I know. It was an overseas order though (US>EU) and organizing a return might be a bit of a hassle. Not to mention that I've paid import duties as well - and I'm not sure if those are refundable at all. Maybe I should ask the seller for a partial refund to compensate for the issue, as this would be the easiest solution.

I would consider returning it. I don't like being screwed around with...
The detect may spread as it may be a problem with the display control matrix rather than a pixel(s).
The fact it wasn't still factory sealed tells the story. Also at that age the battery will have a 50% charge or lower from being stored so long.
I got my new Samsung N10+ from here. He answers his phone and seems like a good guy.
The N10+ box was factory sealed and the real deal. He buys lots of unsold phones and resells them. I blew off a lot of other vendors as the the level of trust was higher with this one. He's got none of your model in stock though or even listed suggesting available new models are rare. Call him, see what he says. He may have a better plan.

Of course. No one likes that. Normally, I would return it as well - but if I do that now, I'm basically writing off 25% of its value that I've paid already for import VAT at the customs. And that makes the situation more complex.
I got in touch with LG's local authorized repair shop and will go there in person on Monday. Ironically, I had my TV's backlight replaced by the same repair shop just a few months ago. Based on their diagnostics and price quote, we'll see if it actually makes sense to keep the device.
Just rechecked the seller's profile on eBay - still 100% positive feedback, not a single negative review on his profile, including for the same model that I purchased. Apart from anything else, this should mean that he would be helpful and flexible enough in resolving this, in order to avoid a bad review.
