amazon, all One X are faulty :(

Hey guys,
today i spoke to amazon germany about the one X, because i had already 3 faulty devices and all devices had the same issue, screen flicker.
The amazon worker said, they tested all devices and every device was faulty, now they are waiting for a statment from HTC. I think its very sad especially for the people who waited for their device, HTC shame on you -.-

Just a bad batch.
Over here in Ireland, very few if any people have had to return faulty devices.

yeah but not in this dimension, i thought a bunch of devices were faulty but not that much, what do you think hardware or software?

The store were I swapped mine 3 times also said there is no "sense" in swapping for a 4th as they are all flawed.

when they cant fix the issue through an ota, then its gonna be expensive for HTC

They may be able to fix it through an OTA. A lot of early ICS ROMs for the Rezound had screen flickering problems, but they've since been worked out. At least there's hope!

If only the level of attention AntennaGate got becomes as widespread for HTCs woes...then we might all get a free case - oh wait that won't fix the Wifi issues, or the flickering...or the yellow spots...

And the transformer prime had the.same.issue, it took 4 ota to fix it. I think I have seen people say it is possibly tegra related

While the problem is very real, I highly doubt that Amazon ripped open lots of boxes and started testing the phones. There are seals on the tape on the side of the box and they wouldn't have been able to resell the device after opening it I think they probably re-tested the faulty ones returned and judged by the number of returns that there was a general fault. By the way, it is easy to determine if your phone is a new never used one or not. When you switch the phone on, if it takes ages to start, going black for a while, it is new. If someone had switched it on, even if they didn't do anything, and switched it back off again, it would not take long to turn on the next time, due to fast boot. Since the fast boot setting is always on after a factory reset, I believe it is impossible to get the phone back into a state of "reset + long boot".
Also, having now been on my 6th phone, every single one of them had flicker. They were not all built at the same time or bought from the same store. I found a test case that could make any of them flicker
1) Battery below 50%
2) Brightness set to 40%-50% (varies a bit from phone to phone)
3) Go to the XDA forum web page on the phone. As the page is loading up, focus on the background and will see flickering as the CPU activity increases during rendering
I think there are two types of flicker. One that happens all the time on some phones most visible on grey backgrounds. And another type of flicker that happens at certain brightness/battery/cpu levels.
Another test case is:-
1) Set brightness very low, such as 20%
2) Go to app/play store
3) Choose "My Apps"
4) This may only work with a considerable number of apps..I tried it with 60. Rotate to landscape, watch very carefully the grey background...and then when the white re-appears, watch the brightness change upwards after it settles.
5) Rotate to portrait and watch again at the grey, then the white brightness levels
A friend bought a HOX just recently and it shows as well on these 2 test cases.

I bought my HOX from an italian ebay seller (a month ago: htc23) and device has arrived with an Amazon Spain package.
Never had any issue: no screen flicker, no flex ..no gap

When you have to set it up just to see it flicker that shows it's NOT an issue in my eyes - 'battery less than 50%, turn brightness to this level, etc.'
I have my phone on auto brightness, let the battery run to nothing sometimes and I have NEVER had the screen flicker. I'm saying there might not be a problem but when you get it under very precise circumstances I think you're deliberately looking for a problem...

I didn't go looking for the problem. I stumbled across it. I am very analytical, so once I find a problem, I determine the test case that produces it. I didn't return any of my phones for this problem. They all had other issues, such as screens that were not seating properly, one that displayed the left part of the image on the right side and vice versa (really weird that one), one that had a massive blue splodge near the middle of the screen etc etc

That I can accept but this whole flickering issue seems a bit far fetched. I've got VERY good eyesight but cannot see anything wrong with my phone so I either have a perfect one or I'm just not bothered by it

Not that much? How many does Amazon DE have in stock? 20? If it's more than that I highly doubt they opened every single unit to determine they're "faulty." The flickering's s/w and any phone is subject to it. Not all do, but all could. Last announcement on May 2 was HTC identified the issue and was working on an update specifically to address it. You're better off waiting until that fix is released.

you are so lucky! mine is an ht23 too, but it does have flickering and suffers when pressing the LCD left side. HTC says it's normal for an LCD which is pressed, i've tried to explain them that this happens only on screen borders, that most devices have no flex issues and so on.....they don't want to replace it.
really disappointed.
my first and last htc for sure.

Indeed, but also how often are you staring closely at the screen while a web page is loading. It hasn't really bothered me but if it was flickering the whole time on a grey background, that would certainly annoy me.

Don't think I've ever seen a panel phone, tv or monitor that doesn't flicker under certain circumstances if you really look for it. Unless of course it's happening all the time in which case something is wrong.
My One X? No problems here as far as I can tell and I'm not about to start to try and make them happen either.
Don't forget also - everyone's eyesight is different. Anyone familiar with rainbow effect on DLP projectors? Doesn't affect everyone - it's something to do with the way the brain interprets the signals.......

Strange, as my last 2 had that issue. Made a youtube about it, send the link to HTC support and they contacted me. They told me that it was not the way an One X panel should react on pressure. Got a refund after the 3rd one, now I'm struggling what to do with my premium navigation license.

If its far fetched why have HTC admitted to the problem in one of the many threads raised by users facing this issue?

[q] screen burn in issues?

I have had my note 2 for 8 months now. Only recently i have heard about the screen burn in issue that is the low life of the screen especially the blue pixels. since i have to use this phone for another 2.5 years or such, what should i do about this? can i get the screen repalced while my warranty is still there and what do i say?
pls help!

blue shouldn't really be a problem.
they made the blue subpixels bigger to compensate for their shorter lifespan.
you can also increase your screen's lifespan by using primarily black wallpapers, black themed apps, and night mode in browsers and e-book apps.
a convenient bonus is that this way you'll also increase your battery life, because it costs almost no power to display black on an OLED screen.

I started having the burn in effects after 6months of usage. And it doesn't follow a pattern it's just a random mark that shows on grey colours. I doubt your warranty will cover that as its a widespread issue that Samsung seems to shy away from, but you won't lose anything if you try to get a replacement just make sure you can easily replicate this issue when you try to show it to the service center.

[Q] Anyone else experiencing AMOLED burn-in / Image retention?

Has anyone else experienced bad screen burn-in / image retention issues with their Note 2?
I've only had the phone just over 90 days, but I've already got some pretty severe burn-in. I use an app for equities trading several hours every day and after a few months of use, the icons and other parts of the app that remain static are plainly visible at all times on any screen that isn't completely black.
For now to slow it down I've re-themed the app and replaced as many static elements as I could with transparent .PNG files and no text.
Any idea if Samsung will replace the display under warranty for these types of issues? (From what I've been able to find, it sounds like they refused to cover it for the S3, then reversed their position and began covering it for some folks - curious what their policy is now)
Here's an example screenshot - this is a blank white screen. It's MUCH more noticeable in person.

Although I havent had it in my note 2 yet, my galaxy s2 had it. I went in to sprint and they swapped it for me because I had insurance. Didnt pay anything. Goodluck though.

I had it bad on my S2. The notification bar and active apps icons were visible on all white and blue screens and so was my keyboard. Sprint sent me home said they don't see that as an issue and the phone works fine so as long as it worked they don't care. Samsung on the other had took down notes then asked me to ship it to them. Never got to send though because the lady refused to be without a phone. As of now my Note 2 has been burning in the notification bar again after about a month of use. I think that's why they made the S4 notification bar the same as whatever ur background is.

Because the damage cannot be reversed, try inverting your screen colors to see if you can get the other pixels to burn in and equalize. I did about 5 minutes of Google research and saw that the blue pixels burn out the fastest, so trying a negative color should burn the rest of them. Inverting colors can be found in Settings --> Accessibility or (in CM10.1) Settings --> Advanced (under device) --> Screen (tab).

Thanks for the suggestion..
I'm giving that a try, but I imagine it'll be hard to even out ~3 months worth of 4-6+ hour a day usage..

Probably, but it is a fix. Your only other option is to let it continue burning out the pixels as before, without inverting the colors, in the hope that you may be able to RMA/warranty the thing. I guess AMOLED screens are known to have this issue. Call up Sprint or Samsung and see what they will do if the problem gets worse.

Apparently for Samsung's Amoled displays, "enough time" equals ~90 days of several hour a day usage.
I was aware that the display could suffer from burn-in/image retention, but I had no idea it would happen this badly and this quickly.

Emergency (I think)

My G4 has just started showing screen burn in, mostly the notification bar. It appears faintly red, and according to the burnt-in time, it was less than 20 minutes ago. I have been using it alot since 3 days ago, and have left the screen static for far longer than this without problems. Does anybody have any suggestions?

Update: things seem to "burn in" after just a few minutes of being on-screen. Only solid white images and text do this, and they leave behind a red shadow on lighter grey or blue colors

update 2: "burn-in repair" apps definitely work, but my status icons burn in again, in the same way, within 5 minutes. I'm honestly crushed, as I loved this phone. It seems I'll have to return it..

Could there be a fix, guys? I'd hate to have to return it

Try this. Use phone for 30+min. Plug charger when phone is on. Turn off phone and wait blue battery sign. Look at top side screen. There you will see al signs. This is my post with same problem: http://forum.xda-developers.com/showthread.php?t=3289496

That's my exact problem. Guess I'll return it and get a different phone altogether. The g4 is a complete bust, it seems. Some have a loose motherboard, some overheat, some have green blobs on the camera, some of their cameras stop working altogether, glitchy lcd's, dead pixel clusters.... Geeeeez

What? I've not heard of most of the issues you described....
I've noticed a small amount of image retention (not burn in... LCD's dont burn in!) when booting into TWRP, but when actually using a ROM there's no issues.
I have no idea what you're talking about with loose motherboards or overheating... I've seen a couple of reports of a green blob on the camera, glitchy LCD's was a single batch of Verizon/Sprint models, and I don't know what you mean by dead pixel clusters.
Sounds like you're looking for reasons to dislike the phone...!

No, I love the phone, believe you me. The motherboard thing has several threads here, and the other issues are mostly isolated, but also mostly carrier specific. You have to dig a little to find them. It's just coming down to risk. I want as little risk for as much return as possible, so for me, all those reported problems (even though they are few and far between) are just as important and search-worthy as things like chipset, ui lag, camera tech, screen size, etc are to other people.
The lg g4, on paper, was perfect in every way, and so I assumed the return on the investment was going to be far greater than any risk. Now that something happened though, I just can't get over it.

It's an electronic device. Logically speaking there will be some with issues. You can't avoid that.
Reading forums isn't a good way to find out about the reliability of a device. People are more inclined to post problems and negativity on review sites and forums. There are far many more G4's out in the wild with no problems whatsoever than ones out there with issues that you describe. Hint: If you have to hunt around to find mention of a problem, it's probably not very widespread...
Chill out!

You're absolutely right man. I went into a cell phone store today, and of all the ones out, the g4 is still the best, the sexiest, and has the most features I like. It also feels SO GOOD in hand. I don't think I'll be able to go with a different phone now....hahaha
I do just need to chill.

My G4 screen is transparent?

Hey there..
So I'm an owner of the G4 for less than a year.. I had a problem with him which was that he got into a boot loop.. I've sent him to get fixed but he came back with another problem... When I scroll down the task manager or open apps with dark theme, my screen shows pinkish parts and transparent icons.. Can any of you help me to fix it?

Your screen is having an image retention issue. Its HW related and goes away only by changing the whole LCD unit.

Oh ok.. And I have another problem since my phone came back from the lab.. The phone charges really really really slow.. Before it used to charge from 0 to 100 in 1 and a half hours when I dont touch it.. Now it takes from 20 to 100 like 3-4 hours.. Untouched.. I dont touch the phone while it charges... So what should I do with it? send it to get fixed..? again? I'm really frustirated.. I bought this phone like 8-10 months ago.. and since the first day I'm having problems with it.. Really disapointed..

Check with os monitor or something similar that is your logd keeping your phone awake (preventing deep sleep mode).
And check your charger as well.
