Sometimes, the very bottom of my screen (digitizer) behaves erratically to touch to where Swype is completely nonfunctional. When I inspect the surface of the digitizer, I don't see anything on it. However, when I take a lint-free cloth and clean the screen, it works again. It seems like its absurdly sensitive to microscopic amounts of debris/oil. Anyone else experience this?
I think I'm experiencing the same thing, but I don't think it is the digitizer. In my case I get the back button acting up on me when I hold the phone in a certain way (due to it's width, didn't have the problem with my 4" Vibrant, plus the SGS2 is more curvy than the international version). I think I'm sliding a part of my palm over the screen or building a connection to the metal rim. The back button triggers in those case casing quite a bit of headache when I have to relaunch the app or click forward in a browser. I order a silicon gel case, which I hope will fix the problem by providing a slightly higher lip around the area.
Well, I got my Nexus on thursday, but immediately I noticed a problem .
At the bottom, the glass is slightly tilted, on the right is raised above the frame, while on the left is recessed ...
these are some pictures I took
I talked to the shop and they told me that they will solve the problem (repositioning of the glass) ...
What I wanted to know is what happen when the phone is opened, because on my current Nexus One, after first service, i have tons of dust entering between the display and the glass, and obviously I don't want the same thing also on this phone
So, do you have some experience with samsung's assistance ?
thanks!
anyone ?
As long as it's purely cosmetic, I wouldn't risk (or waste the money) having some guy open the phone to even out the glass.
Mine is the exact same way at the top of the screen, and I only noticed mine a few weeks after having it just because I was looking very very closely at the screen.
However, the problem it's quite visible on my phone, the difference between the two corners is about 1 mm, and with the glass that protrudes from the frame is even more subject to scratching ...
I don't know what to do ...
there is no one who opened the phone ?
The what you call a "glass" is the whole screen, so there no any way you get dust particles under it, as there no "under" , maybe the glue that hold it not have not dry good, I remember SGS2 have some yellow tint, or maybe it was SGS1, anyway things like that do happen to some devices.
Are you sure?
I have always found that touchscreen ("glass") and the display are two separate things
I'd return it for a replacement, that's an obvious build defect cite that you fear it'll either get worse or become a leak source.
Also, I am relieved I don't have this issue although I'd expect that I'd notice it quickly as you
I've noticed a skewing while using the stylus near the border of the bezel. Lets say 2cm in. First I thought it's because of a parallax effect and respectively the mismatch upon where you actually hold the stylus and what you see on the screen. But then i made a test with a ruler, drawing straight lines across the screwn. Here the effect is clearly visible on aforementioned areas.
This is particularly annyoing if you annotate on the sides of a pdf as in trying to follow the skew, you screw up the handwriting to no avail. Does someone else also have this problem or can try to replicate it?

I just noticed I also have this problem, when I turn the cursor to make it visible it off-set in certain area's. Anyone have this who had it replaced?
Is this not caused by a case having magnets that are too powerful
If neither of you have cases then obviously a fault.
i thought all devices have this problem, mine does and the one at best buy did too. I have a case but it's foldable and the magnets are not near the case when the device is stood up. It's minor, but it's there.
So, who doesn't have this issue when then test the edges using a straight edge.
Just tried it right now and noticed it happens on my tablet too. I'm pretty sure these aren't isolated cases and all the tablets do this. The surface pro 2 which uses the same digitizer also does this.

I'm not using a case and it also happens on my tablet.
So we have here 3 different opinions. Once classified as a defect, once as a cause of using magnets in a case and twice to be normal behaviour. Thx all for testing it out. On my part, I confess to have used a preliminary sleeve with magnets on the closing flap. Though only for two weeks and I'm not sure if it is causal as making permanent "damage". I now use a 360° case with no magnets.
The magnets are not near the area it happens and I also noticed it's not necessarily isolated to the sides There are a couple spots closer to the middle that it occurs on also. Is this classified as a defect covered by the warranty?
Also, as far as the magnets go does it generally happen only when the magnets are close or is it that once a magnet got close once the problem will always be there?

From what we know so far it's not supposed to do any permanent damage.

I am a new user of this tablet, and I can assure you, it's not caused by magnets or cases. Mine arrived a couple of weeks ago, and due to some mail incidents, the case and other accessories that I bought for it haven't arrived yet.
So, I have been storing it on its box, on a table that is away from any electronic device or magnet, and it has this issue. I have noticed it most prominently on the included SketchBook app. That leaves us with 2 options: An issue that is inherent to this tablet/digitizer or a widespread bug.
Happens for me too. But very faint, like a few pixels. I think the touchscreen driver could use an update... There are other issues with it as well as you can see in this forum..
I went for a bike trip with my friends to a hilly region. And there was heavy rain when we were travelling on the hills. After returning from the trip I found that my m8's has lost its quality. Now it is shooting very poor quality picture. Only the rear camera got the problem. What can I do now???

Can you see any condensation inside the camera glass?
Can you see any scratches on the coating on the glass? The rain event may just be a coincidence, and possibly just the bike trip itself caused scratches on the glass coating; which is a very common issue causing foggy or blurry photos.
Can you post some photos to illustrate the issue?
Yes there are scratches

I have this exact same problem that developed since last week and I have no idea how/why. Is this a common issue?
Is there any way to solve this problem. Somebody help us?

I was actually more thinking of pictures taken with the phone, but this is somewhat helpful as well.
Not completely clear from your pics, and probably verbal description would be a little more informative. But it appears from the photos that there are maybe some scratches on the bottom camera (but not a lot) and there seems to be some dots of specks on the top camera (dust or moisture?); although this can just be an illusion of the photo. Correct me if I'm wrong on any of my assessment, as pics can be deceiving. What do you think, looking at the camera glass on both cameras?
If you think the issue may be caused by the scratches on the camera glass, this is actually pretty easily solved. Those scratches are actually from the coating on the glass, and not the glass itself. It seems the intended protective coating is very inferior and easily scratched. The fix is using a mild abrasive (car wax, toothpaste, etc.) or other means to polish off or scrape off the coating and expose the actual smooth glass underneath. This issue and various fixes are discussed here: http://forum.xda-developers.com/htc-one-m8/general/how-to-fix-htc-one-m8-camera-issue-t2803825
Although, it takes a decent amount of scratches to "cloud" the photos. And it doesn't seen that your camera glass is that scratched yet (again, that is just what I can assess from the pics). Personally, I started noticing some minor scratching within the first couple week of owning the phone. And its only been just recently (after having the phone for almost 3 months) that the scratches became bad enough to blur or cloud my photos. I used the solution of polishing with a dab of toothpaste to remove the coating (and pics look perfect again).
If the issue is being caused by dust or moisture inside the camera, this is a much more difficult issue to solve without taking the phone apart.

I think there are lots of scratch which are not visible in those pictures. But are you sure that I must use a toothpaste or something to clean it up or give it to HTC service center?

You can certainly try to have warranty service for this issue. However, I think there have been mixed results from folks on here. I think some have gotten it fixed under warranty; while there are also there are reports on the thread I linked above where folks were getting charged $90 to $300, and even an administrative fee if you chose not to have the paid repair (and have the phone sent back as-is). So its kind of a gamble.
Also, its not clear to me if the "fixed" camera done by HTC is any better than the original (if they have resolved the issue with the coating).

If I do it by toothpaste method what will happen if it gets scratch later on?

If you are worried about the glass getting scratched, you can cut a screen protector to size, or there are some protectors that even include a separate piece for the camera.
But I would expect the actual glass to be much harder to scratch then the coating. I carried the One X (EVITA) in my pocket for 2 years, and only minor scratching on the camera glass that did not affect picture quality.
Had the same cloudy issue with mine recently and thought that it would be going back to the shop. Found a thread about a guy who used a credit card and water to scratch the surface of the lens to remove the coating. Worked a treat for me and my photo quality is back to normal again

I did this earlier on and this fixed the issue I had. So give it a go OP. I just used a q-tip and a bit of water to be honest. It comes off pretty easy.
Today I finally decided to replace the broken screen on my Nexus 7. Everything went well and according to plan, and when turning on the device I noticed it was working fine. However, upon closer inspection it turned out that one thin line on my screen isn't working. It's preventing me from doing SwiftKey flow, and when I tried drawing in Evernote I could see it was skipping over that part of the screen.
What could be the cause of this? I can't rule out that it's the screen part itself, but could it be more likely that I somehow damaged the LCD flex cable? I tried detaching and reattaching cables, so I have doublechecked that. I guess my question is mostly, how useful is it to try and replace the cable? Thanks in advance!

Did you replace the combo lcd/digitizer, or just the digitizer? In the latter case, you're lucky to have just a thin dead band; usually,1/3 of the screen would be unusable. In the former case, if the bezel is bent, however slightly, or there is some glue residue from the old screen on the bezel that causes the new screen to lie on an uneven surface, it would happen. I've experimented enough times to know the bezel has to be absolutely clean of everything and the surface must be 100% smooth and even. If you used strong tape on the new screen, your best bet is the multi-fix touch, as removing it would in most cases damage it.

I replaced the screen + digitizer. I looked at the bezel (luckily the tape I used wasn't that strong so the screen was still detachable) and I cleaned it up thoroughly. There were indeed some glue residues left. However, it was no use, the screen still fails in the same locations. I had high hopes this might be the cause, but apparently not.
I highly doubt the bezel was bent, because I was very careful with it. I will try out the multi-fix touch option, but I'll do that tomorrow as I'm quite tired now. Thanks for all the suggestions!

Don't know if you're familiar with the mechanics of the touchscreen, so I'm adding this for the sake of completeness. Lots of people would post problems and when you try to help, would snap back: "I already tried this and that and other things..." So if you already know, forget the rest.
I've found Yet Another Multi-touch Test (YAMTT) of tremendous help in diagnosing. When you switch from one firmware to another, YAMTT allows you to pinpoint exactly where touches do not register. If the dead band remains consistent, it's probably the screen itself. However, touch detection sometimes varies with the speed at which you touch. I've seen touches missing in some areas, which would register on a second or third or fourth pass. So, go slow in those areas, and back and forth to make sure they're really dead. Tedious process indeed, since you have around 30 variants to play with.

I took a look at that tool, and I posted the result of drawing on imgur: paste "oyIt3bg" after imgur.com (I'm apparently still too 'new' to post links, sorry about that). It is clearly one band, very consistent. I think I should probably talk to the shop I got it from and ask for a replacement. Which sucks, because this particular parts took 3 weeks to even get here. Anyhow, glad I know what the problem is now. Again, thanks for all your help, I appreciate it
Hello fellow dutchie,
I have experienced this problem on my Nexus 4, and after having replaced the LCD+digitizer I also had issues with touch responsiveness in exactly the same areas. As silly as it would sound beforehand, it doesn't seem to be the screen or digitizer. Best... to give up.
