I think the Nexus 4 is an awesome device, but I have a few issues with it that I haven't seen mentioned.
Screen artefacts: On a grey background if I turn the brightness up to maximum I have two strips running vertically down the screen. They are barely visible unless at full brightness, even then you can hardly see them. The best place to see them is in the notification area, I can see them best in a dark room.
Audio (this one is by far the most annoying): If I plug in head phones and listen to music there is a very slight hiss sound, when the music is quiet or at a silent interval. What's strange is if I pause the music the hiss sound is there for like 5 seconds then disappears. It happens with every track, including YouTube and it happens on different pairs of headphones. The hiss sound only appears if I play music, and as I said it's still there when I stop the track for a few seconds.
Image retention: If I'm on Chrome browsing the web, after about 5 minutes, if I swipe the tab away revealing the grey page with the Chrome logo, and then turn the brightness up fully the URL bar and the URL itself are often visible and even readable. It goes away after like 2 minutes but I'm worried it will eventually remain.
Could anyone try out those steps and see if they also have any similar issues? I don't think I would mind if everyone else had them, but I would be disappointed if mine was a lemon.
Thanks for the help!
EDIT: Sorry I should have made the poll multiple choice lol, I voted for the headphone hiss since it was the most annoying.
Concerning "screen artefacts": I got these, but I'm afraid they're worse, because I can barely see them at the minimum brightness when in a dark room (my thread: http://forum.xda-developers.com/showthread.php?t=2052338).
Audio: don't worry about that because I've heard that on many devices (like mp3's or my previous LG Swift); the hiss just stops after few seconds from stopping playback. Maybe it's worse than I imagine that...
To respond to the Chrome issue (ghosting): I haven't seen anything like this so far... maybe my eyes are just not as sensitive as yours

Thanks very much for your reply!
I looked at the picture you posted, and yeah that's exactly like mine I double checked and if I look really carefully I actually can see them at minima brightness, though it's definitely more visible at higher brightness.
Do you have the hiss on your device?
Have the lines, so faint I couldn't careless about them. No hiss or ghosting on mine. I think this is a case of if you want a problem with the device you will find one. Everyone has such high standards lol.

I know, I don't really mind about the lines that much (it's not that bad compared to the artefacts on an AMOLED), the image retention is a little worrying though, but the headphone hiss is just plain annoying.
I see a few people have the hiss, how bad is it? Did your other devices have it?
I have the hiss and lines.

Are you going to RMA it? Or does it not bother you that much? This is the first device I've owned that has the hiss. The sound quality is better than my S2, but that fuzzy hiss sound is annoying.

Oki, now im sure that all these video black clipping is software rendering issues and i experienced yesterday, a perfect playback of all videos, without any black clipping. I experience same as many othersm at first day I got mine Note and with same issues all having at Video on Note thread. With all these black clipping issues on dark scenes and suddenly yesterday for first time ever, I could watch videos without any issues at all.
What happened:
I watch a eps of Chuck and as usual, the black clipping are all over the screen, make it unwatchable at dark scenes, for first time I watch it and with the Note video app.
I changed to MX Videoplayer and same video, suddenly all black clipping WAS GONE and a perfect playback without any more clipping. This is first time ever i watch all videos, without any black clipping and i was totally surprised. I tried play it again on Notes video player and NO black clipping at all.
Then I tried with youtube app, that can see clearly on most videos there and still NO BLACK CLIPPING!
This is totally weird for me, I just dont know what happened and why suddenly all these black clipping at dark scenes that I had with the phone suddenly are gone?
Today I watched the same video and the black clipps are back!
Anyone have experienced this weird behaviour before and why black clippings gone one day and comes back another day? Simpel is, what the heck is going on?
Its a strange issue. With my note it seems to depend on how the video is encoded. Some 720p files play fine, others I get the black block effect. But I am now pretty sure the screen is fine as some videos with lots of black / dark scenes play perfect. No one seems to be able yo lock down what is causing it, me included.
Encoding can definitely affect the banding. H.264 is usually fine, but DivX is nearly unwatchable at equal bitrate.
Hi, just tried this. I have tried sevral HD videos that I have on the SD card and some movies from Youtube and other webs. I can no longer see black level clipping. Rendering looks a little more blocky on some flat areas, like it was 16 and not 32 bits. But hell, black clipping was much more visible.
So if this is just a video driver or decoder issue, I hope Samsung puts the fix on the final ICS ROM. A clearly visible bug with an easy software fix cannot be left unsolved.
I am really going to sell my Gnote and go back to SGS2 because of this BLACK CLIPPING
Just proves its not a screen issue but something else.
Was obvious thought because black clipping was not truly everywhere
Lol

I switched from a purple tint HTC one to this new HTC butterfly s. Here are hardware problems I've encountered.
- purple tint is present 15% of the time in low light conditions especially when the phone is hot .
- when in dark areas, you can see the capacitive touch buttons illuminating the bottom of the screen before the screen turns on.
Anybody else experienced these things? I love the look and speed of HTC products compared to Samsung. But I think theyre not consistent with hardware production

sadly these problems are quite common
1.Yes I get purple tint on my camera but it's just zebra stripes in EXTREMELY low light after prolonged use of the phone. The camera naturally prefers a slight purple tint auto white-balance in some light, this is not that unusual because my camcorder do this as well. Under lowlight with HDR video, unfortunately, the purple tint is totally obvious through the whole image, not just stripes.
2. That's also quite normal.
Additional problems I've had:
1. audio clipping at high volumes with heavy bass (it seems users of the M8 are also reporting this)
2. Touch screen responsiveness with keyboard. (sometimes it lags or "sticks" a bit if you type too fast)

Touch screen don't lag or stick for me it's jus too fast

It's because I have sweaty hands and a screen protector.
I also noticed some stuck pixels on my unit, but it's too late to replace it now.
Don't use screen protector it causes problems when typing

I had serious purple tint, HTC replace the cam and now it had zero purple tint. Quite sure it is a hardware fault at least in my case

Is this a normal hardware problem or physical damage?
Fresh out of the box, headphone jack seemed to make a crackling when a headphone plug is spun around but that went away pretty quickly. Now, after months of use, the headphone jack seems to be going too deep for some headphones, causing this buzz sound and left channel to be cut off, unless the plug is in the right place, but it buzzes/cuts off when the headphone plug is touched slightly. It's especially bad with headphones that have an inline mic/remote. It also seems to have become rather loose now...
Has anyone else experienced this?

This sounds perfectly normal to me. I noticed this with most new audio jacks, be it new earphones or new phone or laptop or whatever. It's perfectly reasonable, though – when a new jack comes fresh out of factory, its surface is not perfectly smooth and by twisting it around, the resistance in the contact changes a bit, resulting in crackling. After a while, the surface gets smoothed out a bit by friction and the effect disappears.

This, on the other hand, really appears to be a mechanical failure.
yeah =/ I'm not sure if it would be under warranty either because it might have resulted me from accidentally pulling out the headphones a few times (happens when I'm commuting and need to make a run). It also depends heavily on the kind of headphones I use. Just bought a new pair of (cheap) earphones today and the plug went too deep causing the left channel to be cut off. A more "sturdy" plug does not do this although it may still buzz if pressed hard into the headphone jack.
I can also see something greyish and red at the bottom - only visible when a light is shined through. It might be dust and paint.
I've seen some reports that this is reported on HTC One M7 and some other phones, with one mod being to put a layer of tape on top of the headphone jack so the plug doesn't go in as deep or attaching rings to the bottom of the headphone plug.
Hello,
a few days ago I bought a new Xiaomi A2 4GB/32GB.
Mechanically everything is fine, but two things seem odd to me:
There is a, albeit quiet, noise coming from the display. In the notebookcheck.com review of the phone they say it uses PWM for brightness regulation at about 1100 Hertz, which is almost the frequency of the noise. It is not always there, but most of the time. I can hear it from about 15 centimeters from the phone.
The other thing is the vibration motor. While my former Redmi Note 5 produces a low hum, the motor in the a2 makes a much brighter sound. The problem I encountered is that it sounds like the device, or something in it, is even vibrating to the motor, which makes a hissing noise every time the motor engages.
Has anybody experienced similar issues with the A2? None of these are apparent on my Note 5.
Thank you for reading and your answers

Either you are very sensitive to those frequencies or your phone is broken as I can't hear any 1 kHz noise from the display

Maybe your phone is haunted ?
I am not sure about the noise from the phone, but I can feel the vibrator extra hiss than regular, Its coming from the camera side, when I try to place the phone on surface, on contact, the camera position side make kind of rattling noise, where some of the parts are loose or not fitted properly.
Hello,
There's a strange rattling noise when I move the phone back and forth like something is loose inside the phone near the camera module. Does anyone else have the same experience? Is this related to the gimbal/OIS or a defect? I don't remember if I had this from day one, just noticed it a couple of days back.
Regards.
I have the same thing, Chinese version. Noticed from day 1, no issues with camera. I'm assuming it's the gimbal
Having something similar when i play games and there is vibration, only noticeable at night when there is absolute silence. I suppose its the gimbal, no problems whatsoever, and only noticeable on no noise at night.
Yes, it is the Camera stabilization system and it is natural.
I suffer from white lines appearing on the screen when playing an online video in different places every two minutes and this problem occurs only at 120hz and adaptive brightness is on, but when the adaptive brightness is off, this problem does not occur, does anyone suffer from this problem and it also does not happen if The screen frequency was 60Hz, does anyone have this problem and what is the solution, thank you
no offence but your photos are extremely low quality, if there's an issue no-one could tell.

Like this photo
I see the same thing.
It flashes only one frame, I assume, but could be 2 or 3 frames.
For me it can be two white lines near the top, or one line more to the bottom.
I see it on YouTube and Netflix...

It is probably "low quality" because he had to use "slow motion mode" or a high framerate camera to catch the line flash... It is a really fast flash of a white line, about 1mm wide, across the screen.
