Hey all, I searched, but couldn't find anything on this.
I'm here in Canada. This is my first Android phone/Touchscreen phone. So i'm not sure if the issue is just my lack of experience or if there is a legit issue.
(btw I ordered my sgs2 from handtec, and got it with no issues.)
Issue:
Dead screen sensor?
Symptoms: (see below picture for example)
My issue is when I am in portrait mode (with the samsung branding at the top), swyping words that start with
A,S,Z (and to some extent W,E,D) letters it "hiccups"? for lack of a better description and registers that i hit/touched both S and Z instead of just S.
When I'm in landscape mode (with samsung to the left) It appears to be the K and M letters. which correspond to the areas of S,D,Z,X from portrait mode....
Question:
Does this happen to anyone else? Is this me? or the screen? or what?
I love swyping, but this just ruins the experience as i can't seem to ever get it to accept what i'm typing/swyping with any word starting with aszd
as an addendum, I can replicate it practically all the time.
It almost seems as if the screen stops recognizing the swype/finger, then has to start again and so then re-registers a starting point, and then the prediction is wrong because of the sudden stop/start.
After looking at the problem a bit more, and using one of the test codes to test the screen, I found that swyping slowing from right to left near the problem area reveals a spot where the line deviates from my swype path.
Possible that I have a bad screen with a dead sensor area?
Here is a picture of what i mean: my finger line never changes - ie: it's straight. note the line that results though!!
Second picture:
I've taken a screen cap on the test page to show you what i mean. I think there is a dead sensor space and the line jumps to the next nearest sensor. It is very annoying, and makes text-tapping, or swyping, very very difficult.
see picture. In this picture i am swyping my finger from right to left. The lines seem to be straight in some areas north/south of the problem area, but when the line meets the problem area, it swerves. above or below.
Sigh, nobody?

Just as an update, if anybody else is/was having this issue: Turns out the screen had a dead spot on the sensors. Had to ship phone back to Handtec (at my cost which sux) for a replacement. Still waiting for replacement.

My Prime has developed a small bright spot in the center of the screen. It's only visible on white or light pages. I didn't drop the tablet or anything, it just appeared. Anyone else experience this?
EDIT: Here's a link showing a laptop with similar looking spots. The one on my Prime is much smaller than any of these, but it's a similar looking mark. I tried getting a picture of mine, but had trouble doing so.

EDIT2: I've learned that the defect I'm talking about is called "mura," or "clouding."

I have 4 of those spots.. three are within one inch and one of them is at least 3 pixels. I also have poor wifi, so I want to kill two birds with one stone. as soon Asus has a fix for the wifi I will rma..
I have the exact same "brighter" spot at lower center of the screen, don't remember it being there when I first got it... it's very annoying, I think I will send it back for repair.
My friend's first prime had that on his screen (2 white dots) when he bought it only visible on a white screen. He returned it for a new one. Thats why its important to check for those too when you first get your prime and put it through inspection, Just open up the notepad like app, that one has a white screen.
got one too. need to send it back for repair, just been too lazy to do it...
Read somewhere that those are stuck pixels. There's an app in the market that's suppose to fix stuck pixels as well.

I'm 100% certain the spot wasn't there when I first got the tablet, as I did a very close inspection of it. Actually, I was reading through a thread in an iPad forum and there were reports of spots like this showing up on some iPads after a while.

Thanks, but this is different than a stuck pixel, which I also have (I found the stuck pixel when I first got the tablet, but it's so unnoticeable 99% of the time that it doesn't bother me). The link below shows similar looking bright spots on a laptop (the spot I have is much smaller than any of these, but it's the same type of spot).
http://pics.livejournal.com/laptop_mechanic/pic/000p062e
same story here. my prime has 5 bright spots (hot pixel) as well. i did not notice them when i got prime last year. pixel fixer can't fix these either. i can live with these spots though.
Sent from my Transformer Prime TF201 using Tapatalk
I have the same problem, 1 bright pixel just below the home screen indicator.
It doesnt bother me that much, its the only problem i have with my prime and knowing theres lots of people with more problems im not gonna return it for a new one, having the chance to get one worse than i had...
My phone had the same thing when I first received it (still does), but it was my understanding it was a "hot spot" created by adhesive or undue pressure in manufacturing. It's not stuck/dead pixels, in my case at least, and my Prime has no such spots.
I however don't know what would cause something like this over time. Seems to me something in the screen is poorly manufactured and overheating...
Sent mine back and was told by Asus that the white spot is a kind of light bleed that caused by pressure at the area, they will replace the panel for me.
I've noticed that mine has a few white spots similar to who you guys are describing. Mine has two about an inch apart from each other near the lower left-middle of the screen, and another near the right hand side of the screen. I don't notice it when other colours are present, but on a white/light surface, it can get very annoying. I'm thinking I might call ASUS and see if I can get it RMA'd since it has other problems as well. The WiFI is actually pretty ok, but GPS is a total bust. I don't really care about the GPS that much, but it might be what I need to send this in. I'm just worried the white spots will get worse with time.
After reading up on this a little more, the name for the white spots we're talking about is "mura" (google "LCD mura" and you'll get some hits). It looks like it's somewhat common on cheaper displays.
Also have this appearing on mine and also didn't have it before.
I have only noticed it in the last week since I installed the latest update.
I only really notice it on the XDA site.
In my case it's definitely not mura (clouding), but more like pressure spots or pinpoints (usually 2-3 pixels in size.) They are more distinctive in shape than clouding. Either way, sucks for any of us to get these kind of issues. I've actually got an RMA # for mine and will be sending it out either tonight or tomorrow whenever I get a chance.
this can be mura, spots, poinpoints or w/e
i can tell you another one..... so i was working very hard on many several things on my tfp.... sending emails, writing proposals, getting images, working on ideas ect.
I started to get annoyed on how fast the tfp goes to sleep, so i decided to put it to Never. So it never went to sleep and it was awesome because my concentration kept going and i was jumping from my laptop to my tfp back to my laptop ect.
THEN.... i decided to go to sleep and i left my tfp opened connected while it was charging. I completely FORGOT that i had disabled tfp from sleeping. So it sat on the Home screen of my launcher.
When i woke up several hours later, i started to use my tfp and i noticed there was a white area that on every screen it was still there.
It was the outline of the icons! This is the reason why screensavers we're created so this wouldnt happen. This is an excerpt from our trusty wikipedia: (btw, apparently this isnt suppose to happen in lcd's but i assure you it happened to me on my tfp, its not that bad though, as i barely see it sometimes)
Before the advent of LCD screens, most computer screens were based on cathode ray tubes (CRTs). When the same image is displayed on a CRT screen for long periods of time, the properties of the exposed areas of phosphor coating on the inside of the screen gradually and permanently change, eventually leading to a darkened shadow or "ghost" image on the screen. Cathode ray televisions, oscilloscopes and other devices that use CRTs are all susceptible to phosphor burn-in, as are plasma displays to some extent.
Screen-saver programs were designed to help avoid these effects by automatically changing the images on the screen during periods of user inactivity.

So, let me ask you this OP, did you by any chance leave your tfp on for a long time with something on the screen? and the glow that you have now resembles that image/icon/object you had on the tfp?
If that happened to anyone, hit the thanks

Nope. I can say with 100% confidence that I didn't leave anything displayed on the screen that could have caused this. The spot is very small, and is just a little random blotch that doesn't resemble any type of image/icon/object. I've tried taking a picture of it with the camera on my smartphone, but I get those vertical bars that you get when taking a picture of a computer monitor and it's hard to make anything out in the picture as a result. Would using a regular camera allow me to get a good picture? If so, I'll see if I can borrow one and post a pic.
Also, the spot wasn't there when I first got my Prime, and it appeared after about a month.
As of now, I've decided against RMAing it, as (1) I'm afraid of getting back another unit with one of the other myriad of TFP problems, and (2) I don't feel like being without my Prime for 4-6 weeks.

Add 1 to the of people with the pinpoint brightness issue, mine showed up after about a month of use.
I am also waiting to RMA or exchange at BestBuy once he seem to have all of the issues worked out since I have one of the relatively good ones now and don't want a broken one.
dead or stuck pixel
i have almost a half inch bar worth of dead or stuck pixels with more grey tint cloudy looking smugges..on the top portion of my screen..i can only see this when the screen has grey or anything in the grey family. i have not dropped, got it wet, or anythin to it..its been working great for me until about 4 days ago. how and what do i do about getting a rma. i have emailed asus but stilll not heard back..its realy starting to piss me off..this is going to be my 3 one..the other two i was still in my return time at best buy and game stop..this one i am not..any help will be great..would post pics but when i take the pics its hard to see or tell what i am talking about..
The bottom-most right-most corner of my display (in portrait) is not responsive to touches and is kind of annoying when typing. I have to usually try several times to get the response.
Stock ROM, only rooted. I just reset it again. I changed the lcd density back to 320 to see if that was an issue, formally at 240.
I used the S-Pen to do these drawing to demonstrate the problem area. The results are strange. In portrait the problem exists but when in landscape it doesn't appear to be a problem. Is this a hardware or software issue or anyone else experience this?
The local AT&T shop says it’s definitely not normal and I can go to their local warranty shop but I don’t necessarily want to get a refurbished replacement if the ICS release might fix it.
I dont have a note yet, but personally myself, I would unroot and take it back asap. Hopefully someone on here will be able to offer a better solution soon, but if not, then I would return it. Hope you get it sorted out.
Pretty sure it's the built-in offset. Go to phone settings -> pen options and change the dominant hand to left. I think you'll find that it is now the bottom left corner that won't respond. Also test with the phone upside down, and it should still be one of the bottom corners (but the other side, since you've turned the phone upside down).

Changing the dominance does swap the S-Pen's ability to recognize that corner and changes it to the other corner.
However, it's stll not recognizing my finger touches.
So to confirm, using my finger with the dominance swapped yields the same results as the images posted with the S-Pen.
When rotated to landscape and using my finger, I cannot reach that corner like I can with the S-Pen when rotated to landscape.
I would believe this is a finger touch issue and not to much S-Pen
Actually. I have a slightly bigger problem. Sometimes hovering my spen above the right bottom corner will trigger a touch. Mainly the space. Enter. Backspace. And m keys. I think I'm going to get it swapped out

that's actually been covered, there's a post here about putting aluminum foil tape on your stylus to correct the issue.
AT&T is sending me another one... we'll see what that one does and hope that it's just not my personal perception.
Replacement arrived and does not share the issue
This may sound like a really simple request, but I've been looking for awhile, due to the two conditions to meet. It's also something I must be able to obtain outside of the market, unless it's something
What's wrong with my Samsung Galaxy 3 phone? (Not an S3 )
One side of the screen touching doesn't work, sometimes it thinks a spot on the screen is being touched and have to keep sending it into the unlock screen until it snaps out.
How does this affect Google Play/Market?
When the phone is upwards normally, the top right side of the screen and down is unresponsive. 2 of the 3 angles are unresponsive, that 1 angle which I can click search on ends up having the bottom two rows of the keyboard unresponsive.
When switching angle to be able to type (as I do texting, have to use all 3 angles) the keyboard disappears and the text is forgotten.
What part of my keyboard is unresponsive when tilted in Play?
Bottom two rows being: (space + backspace) & zxcvbnm
I can search for anything without these characters.
It's driving me a little loopy, the original Android Market was fine, I bet they never envisioned such a problem in Google Play.
What I need:
So due to this, I need to find a market which either has the search (normal way up) away from the right side of the screen. Or at least one which doesn't forget what you've written when rotating.
I know I need a new phone, but having it over-clocked at just over twice the stock speed is enough for anything but gaming (slow GPU). If I had a lot of money I would have bought something a little better at the time. Saving now for something, still researching a best bang for the buck phone second hand.
I just bought my 80 G9. Before I start rooting and romming and warranty voiding I thought I should ask in case these are defects:
In landscape mode, is it normal for the viewing angle to be better if the tablet pointed down instead of up? In other words, if I have the screen down on a table and I'm looking at roughly a 45 degree angle 18" away, it's not good. Yet if I prop it up almost vertical in the same place, 18" away, below my line of site, it looks amazing. Head-on it looks kind of ok, but videos and dark images get washed out. (And using it in portrait is odd too - the screen looks good if I tilt it to the left. Otherwise, the screen looks different to each eye).
The second thing I experienced is, there seems to be a touch dead zone in the top middle of the screen, right where the X's are in Chrome for a second or third tab (it takes about 5 taps to finally get one to land on the X). I haven't found any other dead areas.
If both of these are common issues I can live with them.

Yes, 80 G9.
I'm quickly getting used to the angle.
As for the touch, I ran a drawing program and sure enough there's an 8th inch margin around the whole screen where touching is difficult.
Hi,
i've got the same thing on my 80G9.
After a screen calibration and after the last update, the touchscreen is ok.
The viewing angle is very bad on this tablet in landscape. Try to do a 180° rotation. I only find this solution to watch correctly
Its designed to be optimally viewed using the stand so that's probably why the viewing angle sucks flat and Straight.
I think the dead area is not a dead area its just chrome takes a while to respond due to its huge memory requirements with tabs.
As for voiding the warranty : If you use custom roms from here (XDA) and NOT Official then your device won't be watermarked and won't void the warranty. Just remember to total factory reset/wipe and remove SDE Menu system before you ship it back if it needs a repair.

I installed multitouch visual test from the market, and there was a definite dead zone. The taps would be extremely accurate up until you reached 1/8-1/4 from the edge, and suddenly nine out of ten taps would land on the very edge. Tapping on chrome tab buttons was merely a symptom.
So I returned the G9 and exchanged it (I had drove 2 hours to a store to buy it in the first place, and luckily found an excuse to go back within the 14 day return period). I exchanged it, and tested it on the spot. The accuracy of the edges was much better. I'd say nine out of ten taps near the edges were within 5 pixels (whereas in the center they were dead on). Not quite a scientific test, but definitely noticeably better. And tapping on things near the edge like chrome tabs worked 9/10 times.
That was yesterday. I got home, started playing with it, turned the tablet to rotate it, and no rotate. I know rotation worked earlier in the day while I was testing it - it had rotated while in my lap at an almost flat angle. Still I double checked the rotation settings, did a factory reset, upgraded to stock 4.0.6. It's still stuck in landscape mode.
So I'm out. I'll find another excuse to drive 2 hours each way back to the store sometime in the next 2 weeks, and probably exchange it for something else (with any luck the nexus will be out).
It's too bad too. I really liked it. The price was phenominal, the hardware design straightforward, the os non-bloated, etc. From what I read there aren't a lot of problems with the hardware. I just have dumb luck I guess.

I got two A80S tablets and no problems with touchscreen here.
Just to inform you about some features of ICS:
Have a look in the settings...
- Developer options
- User Interface
- Show touches
After activating this option a light spot is shown after touching the screen.
No need for an external tool to check the accuracy of your touchscreen .

So, I picked up my new V10 today, and I noticed something odd. It appears that the upper left corner of secondary screen has a problem with the Backlight. Just wanted to see if anyone else is noticing this.
It's most noticeable when the second screen is running with the main screen off, especially when there are notifications coming across, the upper left side of the screen is over-lit. Please see the attached couple of pictures for example. (The first picture is hard to see, but you can see the brighter corner on the second picture where I have an email notification). It's also noticeable when the phone is in use and both screens are on.
I'm just wondering if others are seeing this or if it's possible that I got a small defect from factory.
The secondary display does 'bleed', as mentioned in a few youtube reviews. Mine also bleeds. Apparently this is normal but definitely not appealing.
Mine does as well. Only noticed it in my pitch dark bedroom last night.

It's not a defect, just part of using backlights. Look up LG G2x backlight bleed, that was a whole different ballgame, lol.
I'm only seeing that bleed in the dark until that screens dims a bit then the bit of bleed dissappears. I've never seen what you have in your picture.

Yours looks very excessive. In normal viewing conditions, the backlight should not ever be that noticeable. The only time I ever see the backlight on my V10 for the secondary display is in a completely dark room when the screen lights up a little bit because the phone was moved or something. But in this case, the backlight is leaking into half the screen because of how backlight bleed works in an LCD - i.e. it is not a hotspot like you have.
When I got my first V10, it had a hotspot in the upper left corner of the main part of the display. I noticed it immediately but wasn't sure if it was a defect or not. Compared it to the demo model and the salesman agreed, so we swapped it for another V10 right on the spot - no issue now, the screen looks beautiful and the secondary display and notification bar blend PERFECTLY into the bezel during use. It nearly looks AMOLED unless in complete darkness. I would swap your phone ASAP.
Mine does to in a dark room but once it dims the second time when screens off its hardly noticeable. Not what OP has though.
Nothing like that on mine either.
I did notice a very faint glow on the top right of mine but this is as others mentioned...Only barely visible and only in pitch darkness.
What you showed on the top left doesn't seem "normal" at all. +1 on swapping it out. I'd say that's excessive and a defect.

Thanks for the feedback everyone, it turns out that it was not normal. Just rolled back in from the T-Mobile store. Took it in, expecting to be met with some resistance when requesting a replacement. To my surprise, they immediately agreed and replaced it!
The replacement does not have this issue. Glad to get that taken care of, really my only major gripe so far is gone.
Glad to hear it! Happy endings are the best.

Good to hear as well.
So there is no more light bleed on your second screen or it just isn't as pronounced as before?
I have some. The tiniest bit. In a dark room. Totally acceptable. I think this second screen is sexy as all hell
From reviews I knew there was a light leak issue. However, it does annoy me. I wish there was none at all our at least give us the ability to change the brightness. That being said, I initially thought the second screen would be dumb but now I can't imagine being without it. Switching between apps is so much easier now.

Can you try pushing a notification to yourself, while the screen is off and snapping a picture like you did in your first post? I'm curious to see what it looks like because when my screen is off and I get a notification with a white background it's bright on the left corner just like your picture.
I have the same issue on white notifications. Annoying but considering first gen of this type of display...if in future models I'm sure they will have a higher quality one in future.

Went to the T-Mobile store to compare my phone to the display model. After playing with the phones I could see that my second screen display was in fact brighter on the left edge than the display model, so I'll be exchanging mine as well. Hopefully, I get a better one but at the moment I'll have to wait, since they are sold out. It was such a pain in the ass to get the sales associate to see the difference. Unfortunately, she couldn't but when she called someone else over they agreed that it was brighter.
I started a new thread about the dimming of the second screen(probably shouldnt have after reading here). Has anyone figured out how to make the display brighter again with the screen off? I can hardly see it in a lit room..
Thankfully the set I have (HK Dual Sim V10, H961N) has very very slight, almost unnoticeable bleed for the 2nd screen
I exchanged mine yesterday. That top left of BOTH screens was horrible. We went through 5 devices and every single one had some sort of bleed. I picked the one that had the least, and none on the main display. I'm sure LG will revise the HW and fix the issue but anytime you pick up a device with new tech expect some sort of issue.
Mine bleeds a little, but I really don't care.
