Dinc touch screen freak out

Did a search can't find anything specific to my issues.
So I had to replace my amoled screen (Samsung brand), did the replacement everything works fine. But...
now it seems my touch screen has a mind of it's own. It will jump out of apps on me or it's favorite is to jump to the recent apps screen (the screen when you hold the home down). It first seemed to do this when I held it's sides with a little pressure, now it's doing it less. Now it jumps to the screen when I gently set it down on it's back.
I have opened the phone back up washed my hands with dish soap, then disconnected all the ribbons and q-tipped them with rubbing alcohol to clean any oil off. (this seemed to help the side squeeze issue)
I also applied clear tape to the back side of the new screen like how it was on the OEM screen since it didn't come with any kind of shielding like to OEM screen (ie that weird metal fabric like tape).
I still get issues and am not sure what it could be or I could do, taking it to VW is not an option.
Oddy enough, hitting it seems to help it, I am not sure if something is shorting or what it could be. I have removed the screen and reset it back on the touch pad still nothing helps.
I am about to try cm7 to see if it's a software or hardware thing but I suspect hardware.
Thanks guys

Try a new rom, like you said. This will 100% determine if it is hardware or software. If it still jumps around on cm7, then there is something wrong with the hardware
Sent from my HTC Incredible

I don't know a great deal about replacing hardware on a phone, but is it possible that the screen type is different than the stock type? Some Incredibles have AMOLED screens and others have SLCD. I know with computers, if you replace a part that't not compliant with the original then you have issues.
So maybe the screen you put in isn't compatible with the rest of the hardware?
Just a guess...take my advice with a grain of salt lol

No its the right screen, like I said its the Samsung screen just like oem, the slcd is a Sony product used on 2nd gen dincs. plus the screen and the digitizer are two different parts, the screen is not touch sensitive.

Ah ok. Sorry...like I said, never messed with changing phone hardware....was just tossing out an idea.
I've repaired laptop parts like the LCD, touchpad, and such and had issues with the parts not being exactly the same as OEM, that's why I was asking.

It sounds like a loose connection to me... I havent had any problems with my glass unless its greasy or something. It could also be an issue with the touchpad (button), there is a rubber piece surrounding it that apparently MUST be there... Not sure what would happen if I didn't replace it tho I didn't wanna test it out

So I CM7'ed the phone, it defiantly runs better but it does still bug out.
seems to do it more at work when it's set on my plastic type desk.
I'll pull it apart again and double check the rubber gasket, blow out the optic track button and shim the ribbon connections.
seems something is defiantly shorting just a little bit and it all seems to happen down at the 4 menu buttons side of things

so I pulled it apart one last time. removed the screen and reset it in the case, this time for what it was worth I tried very hard to make sure the screen was mounted as high up toward the top as i could for what it was worth. I also made dbl sure the screen was then firmly pressed back in place and all edges were nice and recessed into it's case.
put the mother board back on and dbl checked all the ribbon connection to make sure they were nice and securely seated and not crooked, then snapped the ribbons down.
I also extended the little grounding? fingers (the ones that press against the copper pads) to make sure they would be firmly in contact with the copper pads. I only extended the ones down by the 4 menu buttons.
I con report it's been about 36 hours and nothing has bugged out yet.
not sure exactly what the issue was but i'll keep you posted if it comes back.

[Q] Random touches with replaced digitizer

I replaced my digitizer on my inc and now it will randomly have touches on the screen. I have no idea why this is happening. I have tried two different digitizers with the same problem. It gets worse, i have tried the first digitizer i got on a second phone and this phone has the same problem.
I am running cyanogenmod and have "show touch" turned on so i can tell when its happening and where. The random touches appear to happen all on there own. I can not reproduce them. They do generally happen in about the same spot/spots each time. There are two general areas and when its registers a touch it moves a little, meaning when it touches it self it dances around a little. how ever if i turn off the screen and turn it back on it usually fixes the issue for a while.
Any idea what may be causing this problem and how to fix it?

Funny, I am having the same exact problem. Replaced my digitizer about a month ago and routinely get the "random touches" or just general unresponsiveness while using my phone.
I just assumed it was a side effect of my less then perfect installation but now I wonder if the digitizer itself is shoddy.

Haha, excellent...
Have you considered the trackpad as the possible culprit? I know when my phone does similar things (swiping homescreens, moving the cursor when typing, etc) it's usually because the trackpad is dirty. I can't really think of why the digitizer (assuming it was properly replaced) would be causing that problem..

My buddy Bob had this happen to his Incredible too when he cracked his screen and had it replaced. He had it replaced 3x through Best Buy because each time it came back it would freak out like that. It turns out that something inside the phone was shorting out to the chassis, it would only happen when he squeezed/held the side of the phone. They ended up just giving him a new one after the third time.

Yeah im thinking it could be something shorting but no real way to test. But after many take apart's i seem to have got the screen to a point where it does it like all the time rendering the phone useless. i have put back on the original screen and am seeing if there are problems there. (i got a new plastic housing)

Yeah i have disconnected the track pad and tried that with no change. and i tried disconnecting the light bar for a try and it would not boot. but i only tried once and i could have messed something else up when i put it back together.
i will report back with how the stock screen does and i'm thinking that will confirm that its the replacement digitizers .

Well the stock digitizer is doing the same thing. So its someting on the board, but i have tried it on two different phones.
So im up for trying just about any suggestion at this point. I have 2 phone and 3 digitizes doing this.

Mine does the same thing. I replaced just the screen awhile back.
I thought it might be related to maybe an upgraded screen family and the kernel not supporting it or something..

I usually take off the back and then pull the battery and snap the case back on. Seems to fix the problem until I mess with the battery again.
Anyone know how to see what touchscreen version you have?

ok so i have 3 phones(boards) 3 digitizers. 2 phones are the same hardware version i believe, one isn't. and all three experience this problem. This is even with swapping around the digitizers. I'm thinking that somehow all of these share something similar. All i can think of is me putting them together.
Any idea on what they share?

Just wondering if you ever fixed the problem or got it figured out to some extent?
Same thing is happening on my phone ever since I replaced the screen/digitizer. Took it back apart and cleaned all the ribbon connections and the problem is still there. Thinking it might be a grounding issue possibly since it seems like it goes away (most the time) after I vigorously squeeze the bottom of the phone, by the trackpad and capacitive buttons. But it invariably comes back, and seems to be worse when plugged in to the charger for whatever reason.
Also, since you've also taken apart and reassembled your phone, have you had an issue with the trackpad not sitting flush with the screen? No matter how I reassemble everything, it seems like my trackpad is recessed now and it's even worse when I use the little rubber gasket that was on there originally...

I haven't been able to determine what the problem is, but mine seems exactly like yours. When charging I pretty much can't use my phone random touches everywhere, or it doesn't fully reconize my touch. I just took my INC all the way apart and cleaned everything connections and all. I read somewhere it could be a dirty optical pad so cleaned that good too. Just powered on *Fingers Crossed*

when you replaced it did you make sure you the ground straps where connected to the screw holes with nothing interfering? i pulled my LCD out of my screen on my dev phone because there was dust under the glass. after i put it all back together i was getting the same thing descried in the OP. so i took it apart and noticed that the thread lock used on the screws pealed off and on the ground straps. so i cleaned them up with Alcohol and a cotton swab. put it back together and haven't had it happen sense.

When you say ground straps, are you referring to the two tiny screws that are near the top of the actual screen (after you've taken of the red battery compartment thing and the board)? I remember there being these little metal mesh strips that were in those screw holes that I think I promptly lost after taking the screws out..

yes. after removing the board on the back of the LCD screen there are 2 straps on the top that ground the screen to the frame. the screws had blue thread lock on the bottom. sometimes it will come off when you remove them.
basically make the head of the screw is clean and the metal straps are clean to make a good enough ground.
EDIT:
if you lost the screws you can try to pick up an eye glass repair kit. the ones used for glasses. they have small phillip screws that might work. you can normally buy the kit at a $.99 store.

I was wondering what the screws were for since it didn't look like they were actually holding anything in.. I didn't lose the screws, just the grounding material, which were those metal mesh adhesive strips. Trying to think of what I may be able to replace that with, maybe just some aluminum foil or something? There has to be some better material, I'm just not thinking of it..

the straps fell off? (the straps are on the back and should be soldered to the drivers on the rear of the screen) i wouldn't recommend aluminum foil. try going to a store like radio shack or any do it your self electronic store and see if the can sell you some fine wire mesh.

Hm, I think we must be thinking of different things, cause these were just tiny little pieces of wires mesh that those screws held into place that were stuck to the metal on the back of the screen. Might have to open it up again and snap a picture or two to clarify if I can't find any other grounding issues, etc.

yea thats what im talking about. the 2 straps on top that are screwed in. they need to have a clean connection from the strap to the screw heads that it sits on after screwing them down.

Well I'll be damned, I think that was it! I "borrowed" a little bit of that wire mesh stuff from the back of the screen (it's holding down the screen's ribbon connector and covering other things) and put the screws back in holding little strips of the mesh down and stuck to the metal on the back of the screen. I haven't been using my phone much but the phantom touches and vibration haven't come back, crossing my fingers that it stays this way!
Thanks again synisterwolf, mashed your thanks button a bit
To the OP: I'd highly recommend making sure the screen is grounded properly with those two tiny screws towards the top of the screen.

Thanks for the info guys! Does anyone have a pic of this mesh stuff. I think my old screen had it, but the new screen does not..

Bubbles under digitizer? No screen protector

Hi all. Quick searching leads me nowhere as there are thousands of problems concerning issues I'm NOT having. Sorry for the crappy 3ds camera pic, it's the only thing I have at my disposal right now besides the phone. As I said in the title, I'm not using a screen protector - this is a stock phone right out of the factory with no accessories, albeit aged a bit.
If you'll take a look, you'll see two screen bubbles. The huge funky-looking one at the top started out looking like the one at the bottom, and grew over a period of a few weeks. The bottom one started out really small and doubled in size to what it is now, but has since stopped.
It's really annoying and starting to bother me, but I was wondering if anyone had experienced similar issues, or has any input whether or not I can maybe fix this thing without having to get a whole new screen/digitizer/whatever. No replacement plans on this phone so gotta figure something else out. Any idea what's going on?

Is the plastic actually raised up? Can you see it when the screen is off? To me it looks like the digatizer may be going out, but its hard to tell from a pic.

It appears to be sealed and working fine... just has bubbles. I don't really know much about the insides of this phone, but it almost looks as if whatever is behind the digitizer is slightly warped and might be causing some contact with the glass or something like that. Reflections (off what is behind the screen - lcd? Not the reflections off the glass) tend to bend near the bubbles, whereas everywhere else behind the glass is pretty straight.
Essentially it just looks like water droplets or air bubbles forming on the inside surface of the glass, but it's never seen water before. I don't think the digitizer is failing.

Same problem, can I fix this myself?
Hi guys, I have the exact same problem on my HTC Desire. Touch is working fine, the pixels underneath are ok... yet this thing is expanding. What used to be 3 little bubbles near the very corner moved and turned into this amoeba looking thing after a few months.
Here are a few other shots.
Hope someone can let me know the possible verdict? Is it gone? Can it only be repaired by a professional or can I expect to be able to "clean up" the inside of the screen if I dismantle my phone as it is done here?:

Maybe the liquids from the lcd are boiling from the heat? Sounds dumb but is a possibility

Yikes. Mine is still having the same issues. I'm thinking about just tearing it down soon and figuring it out myself. A little nervous working on something with such small components. Any tips for a first teardown? I need to get a T6 torx and I've already looked at a couple disassembly guides, was a while ago though.
As far as I can tell, I will have to replace either the digitizer/glass or the LCD. If it's the latter I'll probably just upgrade the phone cause they seem pretty pricey.

Ok, I did what I said and investigated myself. Unfortunately, I broke my phone doing it.
The problem is the front glass/digitizer. I couldn't get the LCD off, but I pried it back enough to see bubbles through the glass looking from the inside.
I broke my LCD prying on it, now I have an ugly black spot. Guess I'll be buying an LCD and a digitizer now. Anybody have some spare ones, or know the cheapest place to get them?

There are some digitizers on ebay for about $20 USD. i dont know about LCDs cause i never needed to replace mine but i would assume that they would be a little more expensive. Also, make sure you get the digitizer WITH the bezel because it will make your life a ton easier.

I'd better not touch it then
Sorry to hear about your LCD, D-Lew
Guess I wont be touching mine on my own. I'll definitely break it trying to do the same thing as you. I wonder if it's gonna break my phone if I just leave it as is. I mean, apart from the fact that it is there, it is not affecting the performance at all.

The bubble might get bigger. That's all you have to worry about.

[Q] Nexus 7 (2013) touch screen!?

Hello,
I'm a new to this so don't be mean.
My nexus 7.2 receives a grayish blueish smudge right down on the bottom middle of the screen probably on the 3rd quarter of the screen. Every time I apply medium pressure to anywhere the on bottom half of the screen the discoloration happens. Is this normal?
Thanks

No, that's not normal. Only thing I could think to try would be to try a kernel that allows you to change color and hue of the screen. If that doesn't help it sounds like you either might need to find a new screen and do a self repair or send it off for a fixing. Can't recall anybody else ever mentioning that. Unless somebody else has a better idea though, I think that's your only two options.

Does it look like a light bleed or something? I realize you're new and they might not let you post pictures and stuff, but it's hard to say without seeing what the screen does.

It looks like pressure is accumulating upward at the single point, creating a grayish hue. I guess to be an example, when you press hard on an LCD there will be a rainbow hue next to or on the pressure point. But mine is always at a single spot.

Yeah, I think you have a display/hardware issue on your hands. I was just playing Dungeon Hunters last night in landscape and was hitting both sides of my screen pretty intensively and saw no color changes. If it's bad enough, you'll probably need to send it in for repair or try the DIY route. Sorry, not much else I can think of to help with your issue

Okay thank you for the input. I just have one more question, since the pressure seems to accumulatting in one spot, will that crack my screen? Because the color part is minor and I do not mind that slight discoloration. All I really care about is the chance that will crack my screen.

I doubt it, not unless you dropped it or something where you think you may have caused a weakness in the glass itself. You gotta remember, on all these device there are multiple layers to the glass itself. I'm guessing there might be a small defect in yours between two of those layers. Do you remember it happening after you did something or did it one day just start happening. If it's the latter, then definitely a manufacturing defect. If it's bad enough, if it were me I'd do some research and see how much it'd be to replace the screen. Depends on how long you were planning on keeping the tablet.

I broke my Nexus's screen and digitizer two weeks ago, I got it replaced by a company and that is when I noticed that grayish hue. Should I go back and ask them about it, because I plan to keep my tablet for a while. Also, as I said before I don't mind the color, I just want to know will my screen crack eventually from the increased (I'm guessing) pressure accumulating in that one spot.

I would definitely go ask them. Being that it is a replacement screen I'd go get either their professional opinion or another. Ideally ask them about it and then get another opinion. In a normal situation I'd say no to your screen possibly cracking, but there's something obviously wrong with the screen. I would say it shouldn't but I'd take it back and get a second opinion just to be on the safe side if it's not too much money.

Thank you for your replies.

Replacement digitizers are of various grades. There are those that work but didn't pass QC because of minor defects. These sell at lower prices. It's true that the LCD surface is harder to crack than the digitizer. But it lies on top of another much thinner layer that would crack as readily as the digitizer given undue pressure while handling it. The people who replaced should definitely be held accountable whether it's their fault or the manufacturer's. Hold them to it since if it's a tiny crack now, it's bound to expand with time..

All good here with Lollipop AOSP !!!

I went in and asked them about it. They told me since I broke it and had it repaired, not everything is going to be 100% and that funny looking grayish thing from pressure is the result of them putting in a new screen.

Would that grayish thing really cause my screen to crack? What should I do?

Well then, aren't they saying it's their doing that's causing it? I am not a technician, but I've replaced quite a few. I did it for fun, and a chance at learning what it's made of. Nothing you experienced was supposed to happen with a functional combo (even a B grade unit) , put in place carefully. They're supposed to have the necessary skills. They charged you for it. It doesn't cut it when their reply is that they don't measure up to the job, unless I'm missing something here.
Depending on the tape they used, removing the screen would more likely than not break it. But it's their responsibility. They chose the vendor, and they installed it, and now it has a defect. I'd contact the BBB if they refuse to fix it for free. It's an issue of implied warranty.

Cracked screen

Hello!
Today dropped my phone and screen got covered in spider web. The display itself looks fine, but its covered it spiderweb. The touchscreen doesnt respond at all.
What do i need to do now? I looked at local repair shops, they ask atleast 100 euros. But on ebay i can find lcd display+screen digitizer for 55 euros shipped, or screen digitizer starting from 10 dollars!
Can i buy only screen digitizer (as i understand that top layer of glass thats cracked is screen digitizer?) and replace it? Or changing LCD display along with screen digitizer is a must?

http://www.ebay.com/itm/NOIR-VITRE-...Pièces_de_rechange_outils&hash=item27f98e5d31
So this should fit..right? And are all 3 models LS970, E975 and e973 really same size? Cuz i`ve read people have got smaller screens than original from some sellers on amazon.

Replacing a digitizer is pretty hard and time consuming, that's why people usually replace the whole lcd+digitizer+glass assembly. You will also need adhesive and a heater/appropriate tools. It can be a great learning experience if you don't mind potentially busting your phone. There are no shortage of instructionnal videos on youtube on the subject.
Also, a new G2 is only 190$US .... Just saying ...

As i have two other phones. The g2 mini with Tegra and a razrHD. I'll give a try, thanks for the tip.

Well, i ended up ordering that LCD+Digitzer from ebay. Everything was fine for 2 months, now i have quite large spot that doesnt respond to touches. (See attachment) i already tried disconecting the lcd and digitizer..still same. Is it worth trying to flash another rom? I already flashed stock kdz (had stock before too..)
This happened just today, right after ghost touches went crazy and rondomly oppening everything.
EDIT: That spot is changing sizes..form remains, but it got a bit smaller now. Its truly weird. I put the phone outside for few minutes (its +9C outside) and touchscreen works fine now! What is going on?
EDIT 2: After few minutes of usage, the spot is coming back

I had dropped my LG (more than a couple of times) on its face and it seemed to suffer stroke-like symptoms: one side of the screen was completely dead to touch, and the rest of the screen would occasionally act as though I was touching everywhere which opened programs and messed with the keyboard. I was stubborn and just lived with it and over time, it stopped trying open programs and whatnot. Recently, dropped it again, this time it was a bit more serious. Still no visible damage to the screen, but the "dead spot" moved to the centre of the screen, and again, occasionally tries to open programs and add words to my messages.
At first I thought it all could be related to a software issue. Unfortunately, after installing new ROMS, it never fixed the problem. I bought a digitaliser screen from Ebay as well. I'm waiting on the adhesive tape still so I can't say if this will fix anything. I kind of have a suspicion that its a loose connector (the top middle part of the screen gets super hot only after a couple of minutes of being left on).
I'm just wondering if you have tried taking it apart again to recheck the wiring? I think we may have similar problems (your situation is the first I've come by on the internet that is anywhere close to what's happening to my screen). Thanks so much!
