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

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.

Screen Flicker - Just experienced it and its reproducible...

Hi all, I am on my second device but had up until now never experienced screen flicker at all.
I open up power settings, click on the graph at the top and I can see a the graph kind of lightly pulsating/flickering. I've tried it on fixed brightness levels and automatic and seems to do it on both.
Anyone else able to test it and see if they see it too ?

No flicker here, HT245
Sent from my HTC One X using xda premium

I'm on an HT23 device, bizarre, I've asked a couple of colleagues here at work to check it and make sure its not my eyes playing tricks on me.

Nothing on my HT23.

Before this gets closed.......I'm convinced not everyone can see the flicker and those who can may well experience it to different extents.
Sadly, I can see the flicker of DLP projectors all also know as "the rainbow effect" whereas many others cannot.....

flicker may not be the correct term, its like a really minimal strobe effect, its like the voltage to the brightness is being constantly altered by a couple of percent rapidly.
It's visible on my phone by myself and some colleagues using 50% brightness fixed and auto

and as I said in post 3, if people think this should be in another thread, or I have violated any rules and annoyed people please feel free to get a moderator etc to delete the thread.

I have provided test cases for how to reproduce this kind of flicker before. Today I reviewed another two HOXes of colleagues and so far I have not found a single HOX that I cannot make flicker. I know some are defiantly stating their phone doesn't do it. Maybe there is one out there. But I am now up to 8 phones that I have made flicker and I have yet to be shown one I cannot get to do it!
However, all of them require the battery level to be below 50% to make it reliably happen.
And yes, my wife insists she cannot see the flicker...so not everyone may realise/see it anyway.

There are 2 huge threads about the same thing btw, screen flickering...
I have the exact same thing also. It's not only in the battery menu but sometimes when i'm viewing pics, on screen with grey color is dominant it is visible more but i am used to living with that already since it's a known bug and software related, it is going to be fixed for sure in the upcoming updates. And yes, my wife and some of my friends can also see it happening, the strobe effect, trembling kind of thingy that is hard to explain.

just fyi, i went through 4 phones, all flickered, then 5th and 6th didn't flicker at all. so there are some out there that genuinely don't flicker.

I see it too. As if the refresh rate isn't correctly set.

There are two components to what people are referring to as "flickering."
1) Nvidia PRISM controls (or tries to) the backlight to save energy.
NVIDIA PRISM Display Technology - PRISM (or Pixel Rendering Intensity and Saturation Management) reduces a mobile device’s backlight power while simultaneously enhancing the pixel color to deliver the same visual quality with substantially extended battery life.
It's more noticeable than it should be and is an issue on the Asus Prime also. We may have to live with it in some form.
http://forum.xda-developers.com/showthread.php?t=1542367
2) Graphics issues including "flickering," task bar corruption, funky appearance of the camera app and others are related to the Teg3 graphics drivers which are supplied by Nvidia. HTC acknowledged in the thread this should have been posted in that they identified the problem on May 2 and an update (not 1.29) was forthcoming. The Prime experienced this too and it took multiple updates to resolve. Let's hope Nvidia/HTC gets it right in one shot.

Flickering white pixels in some places?

Just received my second One X from amazon UK (first was sent back due to charging issues).
Been getting some weird things with the screen on this one, which I haven't heard of in the other threads. I have a fair amount of pixels on the screen that will flicker white on certain screens, particularly on the pull-down notification. The pixels seem to be roughly distributed along two vertical lines on the screen, and there's about 20-30, although it's hard to tell since they never flicker all at once. The white pixels don't show up in screenshots, so I don't think it's a software issue, although it's possible, I suppose.
They never show up on solid colors as far as i can make out, but i get them on the camera preview and in the notification drawer (seems to be that shade of grey combined with the fine texture that sets it off). Very occasionally I get it on the bubbles live wallpaper. I also get it when viewing screenshots of the notification pulldown, so it seems to be the colour/texture, not the actual window being drawn.
I can't tell if this is a software or hardware issue.. I've done a few reboots and a factory reset, which did absolutely nothing. It's always the same pixels, which suggests hardware to me, but then it's oddly specific circumstances that set it off.
Any ideas/anyone else getting similar issues?

Edit: re-reading your post it may not be what I thought. Info below for the "usual" screen flicker issue.
It's a well known issue that pretty much everyone has. The backlight flickers slightly due to a voltage drain when the CPU is busy, causing whites and greys to turn a slightly warmer "colour" for a moment.
It's fixed in the 1.29.11 (not 1.29.7) update which just rolled out in Europe and should follow in the UK in about 2 weeks. It takes up to 2 more weeks after the update for it to monitor the voltage of your individual screen and learn to compensate so the flicker goes away.

Yeah, it's not the backlight, it's literally single pixels flickering from their correct colour to white.

So I've been through the standard factory reset crap with customer service, and they're recommending I sent it in for repair. Has anyone had any luck with the repair centre (I'm in the UK)?
Not sure if it's even worth sending it back since I'm still not sure if it's a hardware or software issue. If it's a software issue, will they fix it, or will they just turn it back and go "nope, couldn't find anything"?

I have EXACTLY the same issue, but with two pixels only, I'm almost convinced it's a hardware fault because I'm on a custom rom and it's still there, I got mine without a warranty though so I'll have to deal with it, any suggestions other than acceptance?

I have same issue, i change the rom and now its fine. it was almost on 3 or 4 roms, and finally its disappear

[Q] Getting horizontal lines intermittently

My phone is about 4 weeks old now. Last week I noticed that sometimes, powering the screen on shows some light pink/grey horizontal lines. This is in standard portrait mode.
They are more obvious in medium to bright light and eventually go away after another screen off/on.
I'm using the standard HTC ROM (Sense 5.0, Android 4.2.2).
Would this be a hardware issue?
Thanks!

Sounds like hardware. I knew someone with a Thunderbolt with a similar issue. Next time you see it, don't turn your screen off, but lighly push on the screen in different areas and see if it makes it better (or worse). This may have happened (if its hardware related) due to too much pressure being put on the screen accidentally, perhaps while in your pocket or something.

I did notice the lines again and tried pressing on the screen but nothing changed from what I could tell.
I ended up contacting HTC support and was recommended a 'Dead Pixel' app. Except they didn't specify which one. There's tons on the market and some claim to fix dead pixels. Not sure how true that is or that I even have that problem. Anyone know if those apps work?
Also, they recommended doing a factory reset. Not sure how that would help but I'm willing to give it a shot if there's no other ideas.

I'm not familiar with the apps either, a factory reset would help rule out a software related issue, and is probably the first thing that Verizon would do.

Screen Flickering within a few apps

Has anyone seen the phone flicker currently running it on 120 refresh but during play back of some videos within YouTube or Netflix app the picture breaks up and goes patchy/blocks its maybe once or twice a week. I'm not sure where the problem is as I have ran the Razer phone along side and iPhone 6s plus on the same video / quality and don't get the problem on the iPhone. Razer said it could be buffering but couldn't replicate the issue I was having even with time markings on certain videos.
Just looking to the end users of the phone to see if this is just me or my home network /signal issues or a general concern with the phone

Razer phone screen issues
Yes I've had this issue after the most recent update. I only see it on YouTube and some other videos atm.

Yeah same, here. My only gripe with the phone currently. Happened on 90hz with me.
I'm sure its easily fixed, however I am considering getting the 5T back out the box.

Getting a few fo flickers as well. Running at 120hz. Happens in random apps. Not just one specific

Razer phone screen issues
I'm still sticking with it because of the speakers for now lol but as time goes on better phones are coming out for cheap. I'll be contacting razer after Christmas about this issues and hopefully they will get the ball rolling on a fix.

Everyone who commented, please also say whether this is happening since the MR2 update (newest) for you or whether it was happening before that as well.
Thanks!

It's still happening. I'll randomly get blotchey blocks when watching videos and also the screen flickers like mad on greyish to dark grey backrounds like when in discord. Also it will do a flicker of the background wallpaper when I exit a browser or app. On latest software for me it actually made things worse. It introduced this flicker constantly.
The video getting garbeled was day 1, but the flicker after this update is unacceptable. It needs to be fixed it's highly annoying.

I just started to notice the screen flickering on grey and darker background colors a few days ago as well and I'm not sure what caused it. I'm assuming it must have been the latest update but I've also noticed the flickering seems to become more pronounced when you are actually touching the screen vs when it's just idle.

Just updated this morning, and I had no issues before, but now the screen is flickering pretty badly, especially on white backgrounds like the settings menu.

Hey so I've been messing around with the phone and it seems like the flickering may have to do with the variable refresh rate of the display. I turned on the on screen frame counter in the developer options then opened up an app like discord and the screen flickers everytime the frame counter refreshes. The frame counter seems to refresh every second or so when the phone is idle and I'm not touching it.
When I'm constantly scrolling through something there is no flickering because the refresh rate is at a steady 120 Hz but as soon as I stop and the refresh rate changes the flickering begins again and once again keeps going as the frame counter keeps refreshing.
Now another thing I noticed is if I scroll slowly through discord the flickering intensifies and I assume this is because the screen keeps changing the refresh rate at faster pace because the framerate keeps going up and down.
Hopefully this made some sense. I'm not sure if it's an issue that can be fixed through a software update or if that's just how the hardware is but hopefully it's an issue that can be resolved soon.

Also I've noticed another issue.
1. There is a constant flashing that's like going on super fast.
2. Random big flashes of light that that just come out of nowhere.
This new update has screwed things up real good. Battery life maybe worse as well.

So is this a confirmed bug in the latest firmware only?
I'm on build .853 without these such quirks.

It's been an on going issue and one that's making me feel it's not fit for purpose so going to talk to three as I may get it swapped out. If software can't fix it and it happens often daily for me then it's no good. Razer kinda said they don't know what I'm on about so would be nice for more people to submit a support ticket with them.

Ok so can people confirm whether or not this is related to the last update. I dont have this on my build .853 on THREE UK. I was waiting for the last update to fix the reduced volume and camera but this screen flickering thing is going to be very annoying if thats the case.

Pretty sure the new update is causing it. Never had this issue before the update. Now happens pretty often

Here's another kicker. Now instead of the screen getting blocky it just locks up then the phone turns off. I have to turn it back on again. This is beyond stupid this update has totally screwed up my device.
Come 2018 Razer is going to get a call and complaints.
The flickering is directly related to the dynamic refresh rate. Just chain scroll up and down a page that flickers it will stop cause the refresh rate will be locked.

If this seriously is down to the latest update this is fkd.
Has anyone tried a factory reset after the update to see if the bugs enlisted here persist?
It's worth a try at the least, to totally distinguish are these bugs directly from the latest firmware or clash of remnants from old firmware and the new installed firmware.
I'd try but I'm still on .853 Three.

This is starting to get annoying now. Razer literally flopped with the software side of things. One minute people are waiting for a fix for the current issues, next minute there is a new update which brings even more problems. Most people got this phone because of the screen and speakers but theres nothing but problems. Out of the box update reduced the volume of the speakers and still waiting for a fix from launch day 17/11. Camera is just a total mess, my galaxy note 4/5 camera was much better and that was like 2-3 years ago. Nfc is also a mess. And now people have been complaining about the screen flickering and phone restarting issues. I hope its just a matter of having to factory reset after the latest update and hopefully that will solve the issues. One other question I never got a proper answer for.. even Razer technical team have not managed to answer me on this. Why is this phone only charging at 1900mAH max throughout the whole charge period hence having Qualcomm Quick Charge 4.0+ technology? Am I missing a point here or do I have a defective unit. I replacement charger was sent to me and no difference.

Software and hardware side both failed out of the gate I really should have known better which is why when I get my RMA there's a high chance I'll be selling the phone. Don't get me wrong I'm sure the software side will get much better I have full faith in the Devs such as lex but hardware QA I can't :/

Wish we could downgrade back to the old firmware. This update suckssssssssss
EDIT: Correct me if I'm wrong, but ever since I turned off auto brightness the screen flicking is not as bad. Someone else try and let me know. Or it could just be positive thinking and I'm crazy.
