I'm trying to aggregate a list of hardware issues that might help new Asus owners to decide whether to keep or return their units.
I'm not trying to be a troll or anything. We understand that we're getting a very competitively priced unit, and we're realistic about the short comings Asus has had.
I've been reading the threads, and I'll try to reproduce some of the relevant info here as concisely as possible. If there's errors you see, please reply and I'll edit this first post like a wiki. Hardware issues are kind of difficult to fix, and it's a personal thing whether you decide to deal with the flaw or not. Software, there's hope
1) Light Bleed; hardware
To check for light bleed, try viewing a dark screen.
2) Touch sensitivity; software
Maybe fixed by updated version 3.1. If you find yourself repeatedly having to re-tap an icon, check if version 3.1 fixes the issue.
3) Touch screen dead spots; hardware?
Fewer reports of this, but certain spots of the screen don't seem to be touch sensitive at all. You can easily check for this.
4) Charger issue (gets hot, or just dies, etc...); hardware
This one is tougher to figure out first day, and may take some time to manifest. See thread
. Maybe also want to read this charger thread too.
5) Speaker balance; software and hardware maybe.
One speaker louder than the other? Try this. Although there's some left speaker issue that seems to be related to poor QC. See here and here.
6. Speaker pop; no idea if HW or SW issue
Some have this problem. Other people have a different problem.
7) Dead or stuck pixels; hardware
There's no fix for dead pixels. Stuck pixels can occasionally be repaired with the age-old massage technique, flashing the screen many colors for hours at a time.
8) Dust under the screen; Manufacturing
RMA it or seek a replacement from the retailer. Apparently, certain batches of the Transformer were manufactured in less than ideal conditions and dust got trapped under the screen. It's sealed properly, so the problem shouldn't get worse. Replace if it's a problem for you.
I just picked mine up on Sunday and playing around with it on Monday I noticed the back light screen bleed. Its glaringly obvious at full brightness. looking at a pitch black background, the bottom left quarter of the display might as well be grey. All the other corners/edges have it as well, just not as bad. I'm considering returning it.
That's the only issue I have come across.

Keyboard Dock Issues:
1) Battery discharges significantly in standby, or when dock is docked and off.; Software?
Appears to be a problem with dock's firmware. Future fix is a reasonable assumption, though right now, just detach the dock when it's not in use.
2) Crooked hinge, tablet docks at an odd angle and isn't flush; Manufacturing
Various degrees of severity. The hinge may appear crooked, but the tablet may dock flush. If the tablet docks in a weird way and doesn't lay flat and flush against the keyboard, it's probably best to seek a return if it bothers you. No way to fix it; The holes are drilled wrong, lol.
3) Keyboard does not respond to taps not right-on center; Hardware
Seek a replacement. Very uncommon problem, but there are reports. It's worth noting that it should not be difficult to use the keyboard!
Those who examine the light bleed issue - what menu sequence are you going into to get a "black" screen to better see the light bleed? I just hopped around until I see a menu that's fairly dark, but I haven't come across one that's totally black. And I picked a movie that had dark scenes...but again not totally black.
So, how do you bring up a black screen?

im debating on buying the transformer. do you think i should buy a transformer and hope for the best knowing there might be problems? what do you think the odds are in getting a faulty transformer like is it a widespread issue or is it only with a small batch of ppl
My first Dock didn't charge tablet at all, but all buttons, touchpad, cardreader worked.
Don't forget touchscreen not working. It appears to be software but for some users there is no fix.
I know there are other threads that discuss this topic (somewhat) but I wanted to post this separately because what I'm asking is very specific.
I've had about 8 separate Nexus devices from Google Play in the UK and every one of them has had the same issue:
The display has had a noticeably yellow but admittedly slight (possibly slightly brighter) tint on the bottom and left edges, while the right edge has been dull/dark.
This is specific because there are other and numerous reports of a yellow "tint" across the whole screen. This is not the whole screen, this is very clearly just the bottom third and left edge of the screen.
Some think that this is a "glue" issue that will resolve itself. Some think it won't get better. Some think that it's an issue they can live with. Some can't stand the lack of uniformity.
Well I can't stand the lack of uniformity because in my opinion, on a 4.7 inch screen, I find it distracting to be reading text on a solid background or white and the "white" or background colour changes as I read right to left or top to bottom. I consider a decent amount of uniformity to be a minimum requirement for devices which will be used in the way most of us use our phones and tablets. Manufacturers, seemingly, don't care at all except in the most extreme of cases. It looks like they are churning out whatever they can get away with. In all other aspects, the N4's screen is fantastic.
There's nothing anyone here can really do to help directly but it leads me to a question I haven't been able to find the answer to anywhere by Googling or searching other forums:
What is the cause of this lack of uniformity on these LCD panels? It seems to be LCD specific. As mentioned, some think it's "glue" but then others say not and in my experience the tint issues haven't gotten any better in the time I've had the devices that have passed through my hands.
I don't think it's the LED backlighting but could it be something to do with that?
Does anyone know, from a technical point of view why LCD panels are so prone to this issue with the yellow tints across *part* of the display. It's a very widespread thing as it's been noted on most of the iPhone range and a lot of other handsets too. Is there something inherently difficult for panel manufacturers (in the N4's case, LG) to do to make the panel evenly toned and lit? Surely it can't be that hard at this stage in the development of LCD tech once the manufacturing process is "calibrated" at the factory and underway? I assume these handsets are assembled by robots, not by hand. Is that right? Why is it so widespread? Is it a cost issue? Would I have a better chance of a quality panel by buying a more expensive handset? (Although I've seen many HTC One X's with the same problem - I did see one which was almost literally "perfect" in uniformity and brightness). I'd really appreciate any feedback on this. I know that because it's the "norm", sadly, the common response is to now "accept" the panels and handsets that are out there. There doesn't even seem to be a "higher end" manufacturer where high quality uniformity is more likely - or is there?
Anyone with a good/strong knowledge of LCD tech or the manufacturing process out there that can explain this?
Thanks!
***UPDATE***
I've now attached an illustration to show what I mean. ***It's exaggerated a bit*** to show the effect but illustrates the problem clearly.
Have you tried using a custom kernel to tweak the colors of the screen? The Nexus 4 is known for it's washed out colors so using a custom kernel like Trinity or Franco kernel allows you to tweak the color of the screen to your desire. Of course you will need an application to tweak the colors.
LG is known for light bleeding and or panel uniformity issues, I had to swap 4 LG tvs before I decided to go with Panasonic , my LG ips monitor that im typing on right now for my pc has light bleeding in some areas which results in low contrast. I saw about 13 different optimus g devices before I got the nexus 4 and the screens are beautiful with good contrast, punchy colors and good black levels with no light bleeding or weird tints while my nexus 4 has slight light bleeding right where the signal bar is located. I love this phone and its seems to get the " perfect " one you maybe have to swap a few times and to me the price kind of fits the quality of the phone but then I almost have enough spare cash to buy another one lol can't complain about that.

Thanks for the reply. I've heard elsewhere that LG specifically seems to have poor quality panel uniformity. I think LG panels are used by Apple who have had many, many reports of panel yellow "tint" issues on both their iPhone and iMac range. It seems to affect screens big or small. Having said that, HTC had similar problems and their panels were manufactured by Sony. I would *love* to know what's causing this or what is the reason for the yellow "tint" issue on part of the screen.

I have done all of that and with some success with all of the handsets I've had but because the tint affects only part of the screen in a sort of gradient - the calibration cannot fix it.
I'd much prefer a screen that had a yellow "tint" evenly across the whole screen then of course I could calibrate accordingly.

yellow patches is from the glue used in the optical lamination process, yellow tint is from the display calibration which is often used to reduce banding and gives more saturated/warm look to colors
if your device is affected by by visible yellow patches the only cure is to re-calibrate the display to reduce the effect and don't get the device too hot as it may increase it

Not that I don't believe you, but could you link me to the source of this theory?

Sorry but this is not what my OP is about. I do not have a uniform tint and therefore it cannot be to do with "calibration" of some sort unless I am mistaken. Neither do I have "patches" or "spots". This is very specifically about a gradient yellow "tint" that only affects part of the screen and trying to find out the technical reason(s) for its prevalence in a wide range of LCD screens used in mobile phones and of course the Nexus 4 in particular. I've updated my original post to include an illustration of the effect I'm asking about. Thanks!
I am pretty sure its a hardware fault and i assumed you tried to return it otherwise there is nothing else you can do so i suggested calibration to reduce the effect
I had the same issue, then flashed custom ROM and it was fixed. Go figure :silly:

Guys, I have a terrible issue with my LG G2's screen. Apparently, it looks like it's gotten some annoying burn-ins, which look like white lines running across the screen. They aren't much of a problem for me, but they have got very annoying in recent time. And, it seems like they are becoming more prominent with time. Here are some pics in order to get a feel of what I'm talking about. Can it be fixed with a display tester app? Please help! This burn-ins are driving me nuts! Didn't pay so much for a flagship handset with screen issues. :crying:
By the way, these burn-ins are most evident on grey backgrounds, as shown in the screenshots with a plain grey wallpaper.

This is very strange.
I was under the impression that LCD screens could not get burn-in.
Maybe what you are experiencing is not burn in.
One of the reasons why i came to this phone because i have had the galaxy s2 with LED display and i got status bar burn in as i have noticed happens to many people with led displays. AMOLED included.
Dont quote me on this but Im pretty sure it must be the reflective foil getting too close or tearing on the back of the LCD at a pressure point. Did your phone LCD take in impacts/heavy pressure or anyoone sit on it?

No, not at all. I take great care of my device. Not once has it fallen, nor be treated with pressure on the screen. Once, my mother happened to sit on my brother's G2, however, but he didn't experience any issues whatsoever. At least no similar burn-ins as on my device.
Weird, get warranty replacement then, still sure its probably the reflective layer, but hard to say what else could cause it to warp, since you say it hasnt suffered any abnormal usage.
I have this problem as well, especially in Hangouts since it's grey in color. Not really a big deal though, as it goes away a few seconds later. Now if it sticks, then that's a problem.

Those weird lines seem to stick. But, I wouldn't want to mess with replacement units, warranty repair etc. If it gets too annoying to handle, my first approach would be the display tester app. Plus, these "burn-ins" are less prominent (almost invisible) in outdoor lighting and do not tend to appear as much (or at all) on different backgrounds than grey.
Hi,
Dropping my phone was the worst thing that could happen with my phone.
I found someone who would do the screen replacement and after nearly two months he finally returned the phone two me.
At first glance it seemed ok but closer inspection have shown me that:
- the panel used was JDI instead of LGD so a japanese panel instead of the 'original' LG
- serious screen bleed contouring the whole screen
- highlights on the screen, points in the screen where I can clearly see the backlight being brighter than everywhere else
- luminosity is lower than the original.
The last two points are very annoying. I compared my phone with a phone displayed in a shop and I see that the screen on the shop's phone is brighter that mine, even without adaptive brightness and @ 100% luminosity.
Could this be due to different panel manufacturer (JDI instead of LGD)?
The screen bleed could be due to the screen being badly glued but I am not sure...
But the bright speckels are annoying also. In bright areas this is very much noticable, a white picture shows two small areas brighter which indicates to me that the back of the panel has something behind that 'pushes', hard to explain.
Anybody had similar issues or had his screen repaired?
You can see my issues in the attached screenshots...

I don't think your issues is the panel type, i replaced mine and got a JDI from eBay. I don't notice any difference from my old one, which was not JDI. I would say you just got a poor screen. Not the fault of the installer either, i would try to get hold of the screen seller, or just accept the loss and replace it again.

I can agree that the panel type is not the culprit but the screen bleed is definitely the installers fault.
I am not very happy replacing it again as the total cost would mean that I could have bought a new phone for the same price...
My feeling is that the seller of the screen has delivered a used screen and damaged the silver back of the panel by removing it from the old device (the bright highlights could be from a prying tool used while recuperating the screen.). Too bad , lesson learned = do not drop the phone as the screen shatters very easily and when repairing, find a reliable repairsman...
Accept the loss seems to be the only option in this case...
Maybe I will have to disassemble/assemble the phone myself and do with with extra love and care and sense of detail....

Since the digitizer comes glued to the glass I'm more inclined to blame the screen/seller than the installer. But you know the saying... "If you want it done right...". All the best on getting it sorted and working properly.
So.. Just today ive been noticing the remnants of a game or video name being "left" "burnt" (if you will) into the right top to mid side down the ride side of my display.. Any ideas? Has anyone else experianced this? Trying to recreate it but its only doing it very fantly currently.. And barley noticable.. But after i had played my game for a little while earlier i could clearly make out parts of the game remnants on my display..
I get this too but it only shows up on grayish colors and it goes away after about an hour or so. Happens mainly with 2nd screen but it'll do it every now and then on the main one. Brightness seems to affect it's appearance more as well. It shows up more frequently for me when Brightness is @ 90 and up.
same here , i am getting the pixel burn as well. what can i do any suggestion?
I'm getting the same problem, called T-Mobile they're sending me a replacement unit to replace the replacement for the original that was bootlooping.
For all with the problem, I suggest getting LG to repair it since it should be covered under warranty. Also, just thought I'd add that LCD screens don't burn in, like their AMOLED counterparts. I believe you can describe this as ghosting, or just say the pixel is stuck on the same color if a customer service rep asks. I could be wrong, but this is what I've heard for most of my life. Hope that you guys solve your issues and return to a problem free experience!
Guys try a program called Pure Noise 2 and let it work overnight. I never had this issue with my Note 4 but even then I periodically ran the noise program. Let me know if it works!
Residual Image
I have this issue as well. From Google sleuthing I've discovered it is referred to as "Residual Image" and it is not a "burn in". It was said that the lcd tech used by LG has this "characteristic". It does self correct. And, most definitely appears most often with gray backgrounds. After seeing both of my parents s7 Edges AMOLED screen burn in issues, I feel we have the better tech comparatively. yay?
Screen Retention\Ghosting
Same problem.
Is covered under warranty?
Did anyone solved this?

This is pretty much the conclusion I've come to after researching for awhile
