I had recently purchased this phone off of ebay when one of the screen alignment issues cropped up a few weeks later. Mine was the phantom tap in the upper right hand corner. If you do have this symptom do not bother with the business card trick or jam shims between the screen and the housing. I tried all that. Unfortunately AT&T would not grant me an exception to the non transfreable warranty - never hurts to ask - so I opened her up. The problem is definitly a mainboard issue. This is an interesting read http://forum.xda-developers.com/showthread.php?t=320775 For me, cooling the processor area when the sympoms were present made the phantom tapping stop. Unfortunately when testing this further, I misaligned the battery pack - doh! -this will kill the mainboard. I get a red light charging with no battery installed but otherwise it's unresponsive (and yes I've tried it all). As it was never going to work propery anyhow, I'll chalk it up to another unreliable batch of Hermes. This was a HT648.
So I'm going to part it out. The housing is in excellent shape. The screen+digitizer is in very good shape with 6 <1mm marks(4 in the perimiter and a 4mm airline scratch. Most of these occured trying to shim or gasket remove for the phantom tap issue.
Any part I can take off I'm selling. Just PM me.
I'm already, perhaps foolishly, in the market for another 8525, perhaps the at&t labeld ones have it all worked out....I refuse to do a 2 yr commitment with at&t, saving that for the 8925.
I've noticed a defect on my screen, it looks like a watermark, as if the glass hasn't been coated correctly.
I took the phone back to the shop today and swapped it for another which has the same issue (although not so severe). It's most noticable when the screen is off in bright light.
I'm waiting for new stock to arrive Friday but in the meantime has anyone else noticed this problem?
Nope. Everything fine here. (Or at least I can't find anything )
Ah great, I was thinking it was just me.
I can see it in mine too, around the borders of the glass and especially around the windows button. It mostly shows up when there's fingerprints on the glass, you can see a distinct lighting change around the affected areas.
I'll try to get a picture of it.
Ah ok, found it.
But I don't think that this is a defect or sth.,
My guess: These areas lipophobic? Maybe there was some glue on it? Some you won't see any fingerpints on these areas. This would eplain why you can't see them when there are no fingerprints on the screen.
No big deal for me tough.
I don't think it's glue. It looks like a screen coating.
I've tried removing it with both isopropyl alcohol and thinners and neither would touch it.
I thought it was a plastic cover to peel off - but no
Me too, I thought it was a plastic cover to peel off - but no it does not peel off, i have air gaps under the edges on 3 sides - and the largest is under the htc screen logo :-(
Me too - one long finger top left and some other places bottom and side
pretty sure its some sort of glue residue - you can feel a slight change in resistance
can see it easily by blowing on glass - seems to resist condensation
looks just like screen has been given a quick wipe to clean and they've missed a couple of bits top and bottom.
tried screen wipes and opitcal wipes but no effect
Me too
Recieved mine yesterday, immediately noticed the effect. All along the bottom by the buttons, and along the the left hand side.
Looks like 2 layers didn't completely bond perhaps? The glass and whatever provides the black background.
Tim
me as well, ill upload a video of mine in half an hour, its pretty bad on mine, most of the time it isn't visible. and yeah resistance on that area is different when i rub my thumb hard over the screen it is smooth, but over those droplet like parts there is friction..im guessing that most of my screen is coated and those bits are mistakenly not.
(i thought it was the other way round before)
VIDEO OF SCREEN DEFECT-VIMEO
Same issue here - like an air bubble just beneath the surface of display. My device is slightly affected across the top edge, which is not so bad, but there is a large blob just below the windows key along the bottom edge which is a little distracting. Shame it looks like HTC shipped with such a widespread product defect, as this appears it could be.
Am also finding GPS very flaky - location services more often then not just don't work.
Still, very impressed with WP7. Think HTC could do better ... am wondering what the Samsung is like and what the Venue Pro will be like. Tempted to switch!
same issue here. seems all devices have this feature ...
ps: today in the office i checked again the screen and found out that you can find this bubbles around the screen everywhere. seems it reacts on humidity. strange ...
I've been back to the Vodafone store today as they had received new stock. Both handsets we looked at had the same issue.
The manager at the store said that HTC were going to be issuing a recall and that they were aware of the problem.
I am awaiting a call regarding an alternate replacement.
Ok for me!
same here, especially around bottom left corner, around the left arrow.
I noticed when you wipe the screen hard it disappears, but after a few touches of the screen it appears again.
I wrote to the HTC also and waiting for the reply :
same here - allaround the screen

i think everyone have this problem, specilly from vodafone. and i also have software issue, everytime after using the marketplace, and the icon of some apps were gone, and no preview of the pictures. also the apps download from marketplace not seems to be running, after long time use.....already retun the phone to vodafone, and waiting for the issue to be solved...
My screen is ok. Well, not really oké. Since they didn't put a slcd on it, but a worser screen... Luckily no bubbles. I checked it 1000s times in all kind of lights and darknesses and with and without finger prints. But no bubbles here.
Same problem !!!
I have the same Problem (Austria, A1)
HTC Trophy
Hi,
Same problem here, bottom and one in the top.
Vodafone Portugal here :-(
I bought mine 2 weeks ago. Will Vodafone give another phone?
Thank you.
So I've been using my N7 on and off since I bought it in January. I would've used it more if it wasn't for the fact that the touchscreen responded really bad to touch and freaked out every now and then. It even almost bought an app on its own in the play store once. As I bought it through a retailer in another country I figured I would try to fix the problem myself - and I did kind of.
I tried a lot of things that people suggested in other threads here on xda, reddit, youtube, etc. but the only thing that seemed to work somewhat was tightening the screws around the edges after opening it up. The problem still persisted to some degree and got worse again after a few weeks.
After opening it up again a few weeks ago to fiddle around with the screws again I realized something - the phantom touch problem was gone and the screen had perfect response whenever I was handling it with the back cover off. So I put it in a case without putting the cover on first and I've been using it like that ever since - this leaves the wifi/gps/etc. without a grounding connection though, and I also prefer to use it without a case so my question is this:
Has anyone had the back cover apply pressure/mess with the touch screen in any way?
I have no screen lift at all, but these are the methods I have tried:
Tightening screws(worked somewhat)
Loosening screws(didn't work)
Putting a small piece of paper between the black cable that apparently connects the touch screen and the circuit board in case it was causing a short there due to pressure or something(didn't work)
Additional info: Whenever I remove the back cover, the only place where I have to apply some extra pressure to get it loose is right around where the aforementioned black cable is.

Hmm, have you checked the N7 under a florescent tube light? You should try to view the light's reflection on the n7's screen. It should be 'mirrored perfectly'. If the reflection of the light is crooked/bent, this means your screen is no longer flat. Ie. A flat mirror should show your reflection as it is. A curved mirror will distort the reflection.
If the screen is heavily distorted, this could mean the touch sensors are also 'bent' and touching the screen internals.
Check the reflection with cover on, and also cover off.
If with the cover off the n7, the screen seems to be 'flatter'. Then we could conclude the screen is fatigued by stress somehow by the attachment of the covers. If it somewhat same, then the problem is something else.
Since the cover provides ground points for the n7 circuit and it's antennas, maybe you should try cleaning the contact points on the cover side. There should be grooves made by the contact pins from the n7 on the cover, over time they might oxidize and cause a short circuit.
It is possible the touch mechanism is not being properly grounded somehow.
PLEASE BE EXTREMELY CAREFUL if you are going to clean the contact pins on the n7 side, they are small and very brittle.
Try to see if anything on the cover is touching the circuit board or creating a short circuit somewhere when installed.
These are the 2 causes i can think of. I had this problem too, i loosen some screws and re-check under a florescent light to see it's reflection, and i re-loosen or tighten until the reflection is nearly perfect (screen should be flat and reflecting like a mirror), if not it is bent by stress from screws being too tight or loose at some points.
Then i also cleaned the contact points and pressed the aluminum 'heatsinks' on the n7 side to make sure they dont contact anything else. I did both the same time, following by a switch in ROM and Kernel. So i'm not sure which actually helped. I'm sure i took some stress off the screen by the reflection thing. The grounding also makes sense as an intermittent ground causes stuff to f-up (my car) lol. But you may try n see how it goes. Cheers.
Hey guys so earlier this year I dropped my phone and the screen cracked. I ordered an lcd + digitizer from ebay and installed it myself. Everything had been working fine for a couple weeks but then randomly one day I woke up and the bottom 1/4th of the screen didnt work. Also, my screen is not very secure onto the device. I can peel off the lcd if I desired. I put double sided tape on all the places that a guide showed me but the screen just doesn't seem to stay in which causes dust and other particles to get in between my screen. Could this be the problem?
Some things i forgot
This started off with only a small portion of the bottom part of my screen to stop working. But then it turned into my whole bottom 1/4th of the screen not working. However, the first time this happened, I fiddle with the screen since it comes off and just moved it around and the bottom 1/4th worked again. However the problem reoccurred and I can't seem to fix it this time.
Thanks for any help!
Edit: Forgot to mention that I tried to open the phone again and press down on the digitizer pins to make sure they were secure. Still didnt work
sorry for posing this as it offers no solution
but just to say i have the same situation on a nexus 5.. came compete with frame.. worked for a week then bottom 1/2 inch stopped working
My upper 1/4th of the screen stopped working... Seems to be like a fairly common issue with the LG G2 and some cases appeared all of a sudden without drops or water, some other with a bit of liquid or slight drop to the floor.
In my case I think it was due to excessive moisture when I used the phone while sweating profusely.
A screen replacement is at hand right after I get my smartwatch
Hello,
The left side of the screen shows some Missingno type glitching (I've attached some pics)
Does anyone know where this type of problem comes from?
I had the screen replaced and it worked beautifully afterwards for a couple of days...
I also installed system updates.. so I'm wondering; is this a hardware or software issue?
Thanks for your time and interest

Happened to my wife. Needed to be returned and fixed, hardware glitch not software. I am not sure if it was a screen issue or some other hardware.

Did you have the screen replaced because of the screen flashing, or did the flashes start only after you had the screen replaced?
If the problem has been consistent over the course of two different screens, it would point towards a hardware fault on the sending end of the display connector, right where the ribbons leave the motherboard.
If this problem is brand-new, it might just be that the display connector was not fully secured when the new screen was installed.
Mine is doing the exact same thing. Left side goes all grey and static looking.
I took it apart and reseated the screen ribbon connector and at first I thought it made a difference, but now it continues to glitch out. I took it apart a second time and it has the half screen right at boot up. Sometimes it goes away just setting on the desk but seems to come back regularly. Its only the visual part of the screen, the touch points are still all in the same locations. And when I took a screen shot while it was glitching, the screen shot came out normal. So I am hoping its only the screen/digitizer that is going bad.
I am going to buy a new screen and see if that fixes it. Its only $60 on eBay and its pretty simple to take apart. I will post back if it fixes the problem. That way if someone else has the issue they will know.
Moto x style display problem
I have got the similar problems with display and I will return for warranty repair. I will tell you later what happened.
Downgrade to Lollipop , It worked for me.!
...
(This is the tip for everyone)
I replaced the screen and that seems to have fixed it for now. I haven't had much chance to use it since the screen replacement though. I will update in the next week or so and let everyone know how the screen replacement holds up.
The replacement screen only lasted about a week and now the righthand side has glitched out. I am going to take it apart and put it back together but i think its time for a new phone.
These phone are getting cheap and I really like it so I may just get another. Although the lure of a dual sim version is attractive.
