I think my digtizer has detached slightly

I have this weird issue i have only just noticed. In the middle of my screen, there is almost a perfect rectange of slightly discoloured, rainbowy effect on the screen. It is right in the centre of the screen, and goes to aout 1cm from the edge the whole way round.
Its like the digitizer has detached or pushed up against the screen. I cant remember doing anything to it. And if i run my finger over it, the rainbow effect moves/follows my finger then snaps back to the rectangle (kind of like when you have a bubble under a screen protector).
Also the area under this spot is slightly less sensitive and seems to be giving the odd random input.
Do you rekon this would be covered under warranty? I cant remember doing anything to the screen, and the fact is so pefectly placed in the middle of the screen.

Hey,
Mine does this as well... It's a perfect rectangle, and only visible in strong (especially flourescent) light. Can't notice any differences in input though. Interested to see what people think, and if it's a common problem. Can't remember any incident that could have led to this, I take care of my phone.
In case it helps, it's a UK Vodafone Touch Pro, with the latest HTC WWE ROM.

I have had a similair effect but not a perfect rectangle. somewhere mid screen slightly to the right I had a bubble of rainbow colour. I actually thought it was underneath the screenprotector so i bought a new one to change it. To my surprise the bubble was still there but internally.
I used to have my phone with the protective leather thingy in my jeans. I decided to take it out for a while. And what do you know. after a day the bubble dissapeared. I then put it back in my jeans and checked every hour. The bubble came back. So i'm guessing pressure on the glass internally or something.
Nowadays I dont carry it around in my tight jeans anymore. I use the protective leather that came with it and put it in my jacket pocket instead.
Edit: It has all the attributes xternal listed. The bubble that is.. less responsive random input rainbow following finger. In my case it has been due to pressure on the screen from my tight jeans. Yours might be something else though...

thanks for replies guys, sounds identical to what i have. i thought it was screen protector too, took it off to clean and noticed it was below. wasted blue, i was almost about to edit my post to include exactly what you said about flourescent light.
maybe it has happened from being in my tight jeans, strange that wasted blue and i have the same sized area though.
i have a fuze.

Mine is the Htc Touch Pro from HI, KPN Netherlands.
Xternal i would suggest you don't keep your phone in your jeans for a while and see if the bubble dissapears. Might take a few days at first. just put it in your jacket or something. If it dissapears you know what it is. I don't think this will fall under warranty. if it sticks regardless of pressure you might get warranty...
Oeh i just remember. If the backlight is out you will see a blacker than black dot on the screen where the bubble is supposed to be. if the light goes on its rainbowy fluorecent.

Thanks King, i have taken the protector off and will keep it out of my pocket. The pattern is the same if the backlight is on or off. Id post a photo, but its really hard to get it to show up in a photo.
Im of the opinion now that as you say, the digitizer is pushed against the screen, not detached. Hopefully it pops back

Hey guys.. same issue for a lot of people
It is something like this:

Look at what HTC told me:
New Response From [ Cathy (Malaysia Support (Tech)) ]
Dear xxxx,
We regret to inform you that based on our warranty policy, we can not provide you the free repair on this issue.
If the touch window having some rainbow mark, it is caused by extra force enter to the touch window and it is under user misused. Thus, there is no Warranty Provided.
Thanks.
Best regards.

After some rants:
Thank you for contacting HTC. With reference to your query, we understand you are upset for this issue. But according to the HTC warranty policy, the LCD is not covered by warranty. Please check the attachment for HTC warranty policy. For the "newton rings" issue, we recommend you send it to service center to replace the LCD. Thanks.

Thanks for the help guys, I'll try keeping it out of my jeans pocket for a while. Sounds like this "newton ring" problem in the other therads though. I'd tried replacing the screen protector as well before, but no joy there. Might need to try to get a replacement (took out insurance on it), but guess I'd need to flash back to the carrier ROM.
Anybody know how good Vodafone UK's insurance is about newton rings?
Just read kingpinda's post again, when my backlight is off I can still see the rings, so doesn't sound like the same problem. I'll still try it though, thanks.

I fixed the rainbow rectangle digitizer issue with duct tape!

Long time lurker here... I got the dreaded "rainbow" rectangle on my screen that meant that the digitizer stopped working. I was pretty sad to say the least. I called Verizon and they wanted $95 to send me a new one with the silly insurance plan. I scouted google and saw that many other have had this issue.
So, I broke down and bought the replacement digitizer on eBay. Well tonight, as I looked at my broken phone, I thought that since I was going to be eventually replacing the digitizer, it couldn't hurt to try to mess with it a little. I noticed that the rectangle appears as a thin film between the top and bottom layers of the digitizer. This thin film is what causes the rainbow effect, just like a thin film of oil on top of water.
What got me thinking was that I had just set the screen to beep when tapped, and every time I turned it on it tapped once. This meant that the screen was actually being pressed continually. So, I thought that I'd try to pull the screen away from the bottom a little. I finally got some duct tape (of the clear variety), and carefully laid it over the entire screen. Then, I pulled off at a pretty shallow angle so it would pull on the top layer pretty good.
Well, lo and behold, the screen started working again! And there isn't a hint of rainbow/oilness at all. And it is totally responsive, as before.
So, if you are in the same boat, try some duct tape or similar.
Cheers!

That's pretty good news I suppose, at least one possible DIY solution has been discovered. Kinda puts my mind at ease thinking that one day my phone might not be responsive to touch. I'll have to keep this in mind if that day ever comes. It does make sense though.

Be careful doing this. It fixed my spot, but now the LCD only displays 2 white lines.

[Q] Tiny black circles on screen?

I bought an HTC Evo 4G LTE on Friday along with a screen protector and a case. Anyway, I'm no good at putting on the screen protectors, so I asked the phone guy at best buy to put it on. Fast forward to this evening and I noticed what appeared to be 3 small specks of dust that got under the protector, with a larger one. As I was inspecting them, I found that they were actually tiny black circles (think speck of dust size or even dead pixel size). I'm going to be taking the phone back tomorrow for a replacement, but in the meantime, I'm curious what these are? I've done a lot of googling and the closest two pieces of information I've been able to find say they are either dead pixels because they are about the right size and show up best against a white background, or that they are moisture damage.
The question is, which seems most likely? Can dead pixels manifest themselves as circles rather than squares? And also could moisture damage be so minimal that only four little spots appeared? I should point out that the screen protector was the variety that uses a liquid sprayed on the phone to ensure a good clean overlay on the screen, and also that the salesperson used some blasts of compressed air directly on the screen to try and clean it before applying the protector (I've heard thats a big no-no).

I had a similar problem once with a no name chinese tab.
I noticed a bunch of black spots (square) the size of dead pixels all over the screen. I removed the protector and wiped the screen clean. It was tiny specks of dust indeed.
While blowing hot air onto the screen is a big NO-NO, IMO blowing compressed air wouldn't cause damage. Its the heat that damages the LCDs.

Curious how specks of dust would produce that effect, considering they are not uniformly shaped. Anyway, I've got my fingers crossed now that the problem really is dust rather than a bad screen, since I would hate to start this new phone off the same way I started my last one (returned for defective hardware / software 3 times in 3 months).
Thanks for the input and I'll be sure to post up the results tomorrow when I take the phone into the store. I've already discussed it with the store and since the salesperson was the one who installed the protector, if it turns out to be dust, they will replace the $25 protector free.

Turns out it was dust, or some other contamination, but it was UNDER the screen so that, while you could see them with the phone turned off, you couldn't get at them in any way. Home now with a replacement phone, but as my first experience with HTC, I'm not super impressed...

Green line on Screen

Hello, Was looking for my phone for couple hours today forgot where i placed it. Guess my Son put it in his Bath toy bin and when i found it it was drenched. When i seen it i thought the worst of it the notification light was tweaking out and changing colors from blue to green. So i thought i would try turning on the screen and was completely black. took out the battery wiped out the water and turned it back on i see the green line show up on boot, then booted to the recovery mode and said could not be booted heard a sizzling and popping sound quickly removed the battery, thought my Motherboard was fried then. Put it in rice but i am a busy person i have clients that call me hourly. so i decided to open it. Grabbed my wife's high powered blow dryer and 90% rubbing alcohol and some cotton balls. Took out the main components and dried them completely, seen some corrosion on the boards maybe from previous damages? cleaned it up the best i could with the alcohol and re-dried the boards. and put it all back together and hoped for the best. I was joyed that the fact it booted completely to unlock. but i noticed a faint but annoying green line on the left side of the LCD from top to bottom same as when i noticed when i was at the recovery menu. i tapped on the side it got real thin almost unnoticeable but i'm OCD on perfection. and still find it very annoying upon concentration. Got me thinking, is it the motherboard or the LCD controlled that might be fried or damaged some how. if its the LCD thats a $200 replacement and i can live with that, but motherboard i haven't found a replacement online yet to know prices at that point i wouldn't want to shell out $800 on a new device. Anyone have any suggestions?
Thanks

Any help?

When you say a green line, are we talking like a single pixel width green line all the way down the phone?
If you take a screen shot does the picture show the green line? If no you probably have a damaged LCD screen and they don't correct themselves over time.

Samsung S7 Edge Pink Line - Reason and Solution

Hi guys and gals, so I have determined the cause and solution in some cases of pink screen line.
NOTE: I TAKE NO RESPONSIBILITY FOR FURTHER DAMAGE YOU CAUSE BY TRYING THIS! THIS IS MEANT AS A LAST RESORT BEFORE REPLACING THE ENTIRE SCREEN/DIGITIZER!
Problem :
Problem is with the flex ribbon cable that attaches to the screen. I had the pink line and had smashed my screen, so I ordered a new one and replaced it.
Cause:
The high heat of our device melts the glue that attaches the ribbon. I learned that because after speed testing kernels on the device with the new screen, the line eventually reappeared.
Solution:
Heat can also fix the problem, if it hasn't gotten too bad. If you can find the pressure or position where the pink line goes away, use a heat gun or hair dryer to warm the area at the top right of the screen, usually at the selfie camera. Heat from above so you're heating the screen and the top of the device. Once it's hot, but not too hot (yes frustrating but only do this as a last resort before buying a replacement screen), then allow to cool naturally back to room temp. If the line was absent the whole time heating and cooling, there's a chance you've fixed it.
DANGEROUS LAST RESORT:
THIS IS 90% CERTAIN TO CRACK YOUR SCREEN! Now, if this didn't work, and you're Very adventurous, you can search Google for s7 edge ifixit, and see how you can CAREFULLY heat the glue around the whole screen. Don't remove the screen, as it WILL break! But perhaps you can get a pick or card into the top just enough to see the flex ribbon, use same pick or card to lightly press the ribbon as you heat and cool as per above instructions.

It would've been awesome if there was a video tutorial.

Someone tested it ? Some video tutorial could be really helpfully to repair this. What temperature should i go ? I think the best option will be to use a hot air soldering station but i need more info.
Best regards RufleX

Hello.
I work allot with prints directly. Scripting flashing repairing and debug in field. So I can asure you on a fact this will work.
The only part I'm questioning is the fact if they did use glue for a flat cable. Since logic wise for differemt prints ypu use a lock way cheaper and easier to replace parts.
If they dis use glue this fix will only be a temporary one. Since the glue will spread more and more. Each time you will do it this way.
So like I said. What the best man said is true. It will work. Only if it is glue. It might be possible it will only work for like 3 months or so. Depends on the ammount of glue and connector type they use. Can't say anything about that part. Only reason I reply because no one else did since u asked this question.

Yesterday was a really hot day (well for England) and part way through, I noticed a very thin pink line appear. The phone was hot but not entirely my fault.
Anyway, it disappeared a few minutes later and hasn't returned. Slightly worrying though.

Back today. Pressing hard on the top right actually makes it thicker. Gone again as I type this message.
Is it covered by warranty?

Ill go with the first guys suggestion. As i ve done this before with many electrical products. I will not go sticking objects into my waterproof phone.

Did anyone try to open in via the back and push something in to hold the connector like in this s6 edge video ?
https://www.youtube.com/watch?v=Ed2VvM7uEIE

there is a whole group on this problem
see fb group
https://www.facebook.com/groups/1898027130464533/

I had this issue repaired under warranty. What surprised me from the beginning of owning this phone was just how hot it would get when the screen was on, firmware updates and so on. Sometimes almost too hot to touch. Since the repair it only ever gets mildly warm. I didn't get a repair sheet when the phone came back but I wonder if it was just the screen that was replaced or whether the screens have been redesigned?

Has anyone tried the last resort?

Nothings helped I brought it back to shop where i bought it . my device has 2 years warrenty . I get a new device.

it is not because of heat, i used mine for 2 years, during the summer (40c) with heavy use, and i have no pink line. it's just a manufacturing defect.

I picked up a used s7 edge with a cracked back glass. It is now showing this pink line issue. I started to notice it after it had been in my front pocket. I know it did not get hot in there ( sure would have noticed it there ), but it was definitely put under pressure when I would sit. Most of the time the line would go away by turning the screen on and off a few times and would stay gone until I carried it in my pocket again. The other day it came up and would not go away. I finally downloaded LCD-Test and swiped through the RGB screens a couple times and it went away and hasn't returned. On doing some experimentation I found that by pressing near the front camera I could create the issue but it would go away when removing the pressure. Confirming that it is indeed a physical issue that seems to latch on if pressure is applied for enough time. I have a new back glass coming and am wondering if the heat I will apply in removing the glass will help with this issue. " Will post result when completed " I am also looking in to a case that will take the stress off the top corner of the phone when it is in my pocket. Any Ideas ?

Pink Line Issue
Hi everyone, I have a question about pink like issue on S7 edge.
I've been living with the pink line since early this year, recently the line is getting too thick I couldn't bear with it anymore, so I decided to get it changed.
The question is, I've read threads that says the pink line appears are because of design flaw. So if I replaced the screen (which costs a bomb) will that appear again after a year of use?
Side note, my pink link appears about a year after I bought this.
Any owner who suffer also from pink line issue, are you still facing same issue after screen is replaced?
Thanks for your time.

Here's a new observance of the pink line issue. After a day with no problems hanging around the house. Yesterday morning I went out into below freezing temps. Pink line came up almost immediately. ( Something in top of phone changing due to temp ? ) Upon getting home got it to reset and left it inside the rest of yesterday and all of today. ( No pink line ) interesting.

Once again today, have stayed inside and no pink line.

1. Try the flashing colour solutions
2. Try some pressure at Samsung logo
3. Try to get warranty fix by Samsung if your phone isn't damaged
4. Here is a video on how I permanently fixed mine :good:
youtube.com/watch?v=dacCTRU6snY

Thank you man, I replaced the screen and after a fex months the line appeared, it dissapeared whan I pressed or lifted the screen a bit so, for me, was easy to lift it a it than heating and glueing because that part off the screen didnt have glue.
Tnx for your post I fixed the line.
