replacement Mytouch 4G Screen digitizer issues - myTouch 4G Q&A, Help & Troubleshooting

Hey all,
I replaced my girlfriends shattered digitizer a couple of weeks ago. Everything went great. I attempted to reuse the adhesive that was originally on the phone but alot of it was not any good.
So after putting it back together using what i could for the adhesive, the phone booted up and worked fine. But after sometime of using it my girlfriend started to complain about it not responding to touch correctly. Random times when touched it would act like she was touching somewhere completely different. Or it would act like it wasn't even being touched. To fix that issue you have to put it to sleep and then reactivate.
A good example would be if you were on the phone dial pad and trying to press 9 it would press 2 or 5 or 1. Or sometimes it would just not activate anything. Sometimes it would even "press" something without it ever being touched.
I did replace my old iphone digitizer and had the same issue. Not sure how to fix it. My only other thing i can think of is maybe getting some adhesive and applying. But i want to see if anyone has had this same issue or if they have a fix?
We've reset the phone to factory settings, rebooted. I have no more ideas.
Also where cna i get mytouch 4g adhesive?

Bump....anyone?

This thread might help you out. Someone in there also mentioned that you can use the same adhesive used on iphones, or 3M adhesive(whatever that is..)
Hope this helps you out a bit.

THanks. I will have to give that a shot.
Anyone have any other ideas? Any one hit this issue before? There has to be atleast one person.

Hi there, this is what I use to re-adhere digitizers when I repair iPhone digitizers and MyTouch 4G digitizers: http://www.ebay.com/itm/37051618015...X:IT&_trksid=p3984.m1439.l2649#ht_1118wt_1141
Make sure that all connections inside the phone are properly connected, the issue with your girlfriend hitting a button and the touch not responding correctly usually indicates a defective digitizer or that a connection came loose or maybe moisture got underneath which will cause the digitizer to fail.
I hope this helps !!

I have the same issue. I replace one digitizer for a customer and she complained of certain spots not responding.
I replaced one on my phone and it does not respond in some places. Like i wouldnt work when its on horizontal mode.
I would draw a straight line on a drawing app and it goes down fine and get crooked towards the bottom area. almost like a lightening symbol.
The digitizer i got is not original. One of my original digitzer is acting up too. Tried it on different phones and its still the same.
I also tried using the adhesive tapes.
This is too much of a problem.. Wonder what the issue is...

It'd be ncie if we could get some more advice here. Or even some more reports of this issue.
@krnchonnom: Where did you purchase the digitizer? I picked mine up for repairs universe. Wonder if they got a bad batch.

I replaced my Digitizer this past week and I'm now expeirencing the same thing... Has anyone proven that using new adhesive solves the problem? This is the adhesive I used when replacing mine, http://www.repairsuniverse.com/adhesive-strips-for-touch-screens.html

Hey I had the touchdcreen problem after the OTA update from T-Mobile a couple of weeks ago. Now for the last two days it disappeared. I think it was software related...

How could it be software related when I never had a problem with my old digitizer before and after I shattered it...
I took apart my phone once again today and spent about 2 hours sizing and cutting new adhesive strips and it appears that I have relieved the issue so that it only happens now and again, thus allowing some use out of the phone but now the digitizer is stuck to the LCD and making part of my screen looks like a piece of glass on top of some liquid ready to go under a microscope... I'll put up a pic tomorrow.
I'm just about to the point where I might just purchase a digi+LCD assembly instead.

Sooo. .. you guys replaced the digitizer and still no go, but cannot fathom it may be software related... May not be but mine was when stupid T-Mobile said it was hardware. I would type a certain letter yet it would type three others making it impossible to text. Just sharing my experience. Hope you guys figure it out.

here is what it looks like
problem solved. My adhesive tape was too thin. I doubled the adhesive up and now I'm good, except for the intermittent unresponsiveness. I have to lock the screen and unlock it again to get it to work again...

I'm about to tear back into my wife's MT4G for this same issue. She cracked the screen a couple months back and had to use a MT3G for a while!
I bought several busted MT4G's off of ebay to tear down before I took hers apart. It really helped knowing where there are snaps and screws and such before you do the real thing.

touchscreen does not "untouch"

Hi Folks,
I'm reading this forum since about 1,5 weeks, as I got my first smartphone then. Unfortunaly I sent it back today, as it got broken yesterday. It has the problem, that the touchscreen doesn't untouch. I made a picture:
I can get rid of this touched area by pressing on it with my fingernail and move it to the bottom.
I think it's from that lether case. Anybody else ever had a problem like that? Probably with another phone type?
Looks like condensation under the screen to me.
Reapply screen protector... That's it..
I thought about water also, but under the microscope we have seen that it wasn't water. I was able to remove it restless until I touched it next.
I removed the screenprotector, but that wasn't a solution.
Unfortonaly I had to send it back today, as I'll get a brandnew one within the first 14 Days after delivery
Wow that's new. Mebe condensation.
Maybe since the touch part is 2 layers, Glass and Plastic screen hovering on top of that, that it got too hot somehow and that the plastic part got stuck to the glass. mebe if you had let it cool or something it woulda unstuck.
Was the phone near any heat or in direct sunlight?\
This looks like a cracked digitizer, a touch sensitive layer above the screen itself. The screen underneath usually seems to be fine, but it doesn't have the touch capabilities anymore. It has a look of spilled liquid and you should be able to see dots of the touch grid, you can't see them normally. It happened to me on my Orbit2. I think whole screen has to be changed...

I thought about something like that too. Has the digitizer a "spazial" filling, so that you have a "soft feeling" when you tab it with the penzil?

I had the phone in my trouser pocket every day. No sunlight or heat. I tried cooling down...no chance. I had a Cassiopeia once and had a waterdamage to it. There I was able to get the water out of the touchpad by having it on my heating for a few days. But it looked not like this here.

I had the same screen protector...strange. I removed it before i sent it back. After removing I tried, but the error wasn't gone. I think better remove it before sending it back, but you should also try if this fixes the problem. Tell us if or if not

i hope well
Just had the same problem with my Td2. Not impressed. The phone was fine one minute as listening to my music on it, popped it in my pocket went upstairs ang got this blob right in the centre of the screen.
Glad I took the insurance now as this is going to have to get sent back. Not overly impressed as only had the phone for 6 weeks and having a problem with the build.
Just a quick question for those that had this problem. Was the damaged screen visible under all types of light?
I ask this because taking into different rooms in my house and different types of light it seems to disappear, then reappears under other light sources. I will test in the daytime tomorrow but am now starting to wonder exactly how long it has been there...

My "blob" couldn't be seen when I looked straight from above. As on my pictrue I had to look from a angle to see it. Also it was hard to see under bright daylight. Hope that helps.
But I have a question also: You all used the leather bag shipped with the phone? I think the case isn't plain enought inside. I think there is a higher pressure one the display while wearing it in my trouser pocket. Anybody else who can tell more about that?
I've the same problem, at least I think it is the same. Touch still works fine, but it seems like there is some condensation underneath the screen.
I can confirm that it has nothing to do with the screenprotector.
If I put my finger on it, it moves to the sides. Sometimes it seems to be gone, but after a while I notice it again.
It's a very colourful stain. Can I claim warranty for this kind of 'errors'?

As you are the 4th in this thread I think so
It's not under warranty of HTC, at least that's what they told me...
Did somebody else contacted HTC about this problem?

too bad it seems like they classify it under 'cracked display' - and according to the user manual it is not covered by warranty.
Probably, but I think it's just an error of HTC. The way they treat their loyal customers is, in my opinion, verry disappointing. It was the same with the problems everyone had with the TytnII.
Today I got my phone back from my provider...the same broken one. In the letter they told my I sent it back too later
Now I'm dissapointed from o2 Germany, cause the customer support told me what to do and I did it.
guys i had the same problem (http://forum.xda-developers.com/showthread.php?t=519441) and i got a replacement. but i tell you.. this is caused because one time the phone got hit by pressure on the screen and the screen itself kinda felt into the phonecase. check out from the side.. you probably will see that the screen is lowered - then when you use fingers on the touchscreen this blob appears. in my case the screen didnt work anymore as soon the blob appeared... but was able to get it out with some tissue and rubbing.
also i saw some oil liquid under de screen - depending on the light outside.
so.. just take care.. this phone is very sensitive to any pressure on the screen and using it in a trouser pocket is already dangerous!

[Q] Derp! I dropped my Aria!

The digitizer cracked. Almost perfect straight line just below the soft keys, and just above the trackpad, and the bottom left corner was pretty nasty looking. It worked for about a week and stopped. I had it all apart, and no connections are loose. The actual digitizer seems to be intact, but the class is missing entirely below the soft keys (it didn't stay together during disassembly). I was going to replace the digitizer, and eventually upgrade to an Atrix. I'm stuck on my junker Samsung jack in the meantime.
Anyways, my question is, is the digitizer not working because that bit of glass is missing? I can attach pictures later if you guys would like. I'm concerned about putting money into this phone if I can't know for sure if it's going to work when I'm done. I have a feeling that the problem is bigger than just the bottom of the glass being cracked/missing, because the portion of the glass that is actually touch sensitive is totally intact. On the other hand, is it possible that it isn't working because the digitizer depends on the entirety of the glass being there (since the glass is an insulator) to output the correct resistance values? If somebody with more knowledge on this could help, that'd be great. I used to occasionally get the touchscreen to work a few minutes at a time, but I now get no response.
I've done all kinds of searching for more specific answers with no luck.
Thanks for your help!
I am in the same boat bud. I cracked my screen pretty bad and just dont want to dump money into this little thing when there are some sick phones coming out this year. My has a ton of cracks all through the screen and it works perfect still, but I also have all the glass intact,for the most part anyway. I would have to guess that its the missing glass, but I am far from a pro so...yeah. Last I checked the aria digitizers were kinda steep in price, have you found any "deals"? Good luck to you sir.
I ordered my digitizer from wholesalegadgetparts.com they're reliable and have fast shipping. The installation can be a bit tricky and usually leaves you with a malfunctioning proximity sensor if you're not careful. Let me know if this helped or if you need assistance.

Well, out of curiosity, I fired up the phone tonight, and surprise surprise, it worked. Looks like the proximity sensor is shot though. When I take the phone aay from my ear, the screen doesn't turn back on, and I had to pull the battery to hang up. I'm going to try and work some magic and see if I can get an upgrade to an Atrix or Inspire next week, and I'll report back. Thanks for the help guys.
mine broke too
had the same problem - had to pull battery to get it to turn off - just wouldnt work.
I ordered a replacement - tried to replace it myself
couldnt quite get the glass to fit back nice an snuggly - and couldnt quite get it right .
ended up just buying a new one -
If your contract is almost over i would try to hold out for a new phone - so many nice new ones coming out...
although I love the little size of the aria

[Q] Replace Digitizer Now Won't Turn On

Hi. I purchased an Evo 4G from some dude on Craigslist. I verified the ESN was clean via checkesnforfree.com and I was well aware it had a cracked digitizer. I purchased a new one via ebay and it came in today. I watched YouTube videos over and over as well as followed the steps on ifixit.com and thought I did it right. That is until I turned it on and it vibrates and then the screen flashes white briefly and then that's it. It remains dark.
Any ideas as to whether it is a faulty digitizer? I have checked, re-checked and even re-checked to ensure that the cables was set in snugly and that the latches were latched.
Again, the phone was working just fine prior to me replacing the digitizer. It was dim but it responded to the touch and all buttons seemed to function normalls including the camera and speakers.
Any thoughts or tips would be appreciated. Feel free to email me as well.
Thanks in advance.
Take the battery out, replace it, does the phone turn on while holding volume - ?
Having trouble with AOSP? http://forum.xda-developers.com/showthread.php?t=1295702
That sounds more like the LCD is bad. If you say the screen was dim, that's the LCD, not the digitizer.
I had that same problem, but it turned out the ribbon for the lcd was not fully inserted. So I pushed it in more and it turned on.. Hope this helps.

replacing digitizer, I bent a couple of hair wires on one of the brackets!!
I bought the evo 4g a while back for 400 bucks, within a few weeks I dropped the phone cracking the digitizer. Done a ton of research on how to fix it, then ordered a new one plus all the tools to fix it on Amazon. while I was putting it back together, I was super careful returning them to their brackets, however, a couple of the tiny little hair sized wires on the base bracket bent crossing over some of the others, I tried to straighten them out but of course this didn't work I suppose, when I got it all back together, the phone will not turn back on. I have looked in millions of online places on what I can do but found nothing, I have also called the Sprint repair store who basically laughed at me and said I threw away 400 bucks. the only thing I can think of aside from tossing my money in the trash, is hope and pray that I can find someone with some extra brackets and hope and pray I can somehow replace it without screwing it up again. Please PLEase PLEASE, if anyone can help me at ALL I would be so very greatful!!!

Need some help, dead digitizer or what??

Hey guys, I need some opinions about my problem, check my video http://www.youtube.com/watch?v=yeApacv5_gE&feature=youtu.be
I think it's digitizer fault but before buy new one I need to be at least 90% sure its digitizer, tried to load many roms, pds fix...
Anyone? Somebody must know
Well honestly it is hard to say without actually having your phone here. But you can almost be sure of this. It is most likely either the digitizer or the multi pin socket that the digitizer plugs into. I am working on one right now that went into a swimming pool and the socket is bad. It does the exact same thing as yours with any digitizer that I try. I'm currently looking for a way to remove the corrosion from the inside of that sucker. Gotta find some kind of spray. I can't seem to get it good enough with emery cloth or scraping... On the other hand I've replaced the digitizer and fixed this same issue on my sons Atrix.
In case you decide that you want to try to replace it here are 2 on Ebay that have the frame built in. Link1 Link2 So far I've bought 3 that were assembled this way and it is so much easier than buying a ditizer alone. No messing with double sided tape or worrying about backlight bleed.
Hope you can get some relief.
Dude, I've got the same in the same places! It have to be factory defect... there is too much digitizer problems...
Yes its very good smartphone but too much bad digitizers disqualify it, so JdgM3NT4L sometimes when I squeeze frame bottom of the screen works fine but only for few moments, so there are three options: need to replace adhesive sticker, replace digitizer and pin socket. Damn even if I want sell Atrix for parts I am not sure if all of them are fine
I used to get that a lot, phantom touches that make the phone useless until I turn the screen off and back on.
Cannot say for sure but when I stopped using alcohol wipes to clean the screen and reduced the amount of static it was exposed to (keeping it polyester pant pockets seemed to make it worse believe it or not!), it seemed to pretty much stop.. now I've gone months without the issue.

Well, the socket is on the motherboard, so no replacing that... For 30 bucks, I would try the digitizer. I should have explained the part about water damage. That's one of the few ways that the socket would have been damaged. That's kind of what I was eluding to when I mentioned not having your phone here. If I had it here I would know the history and whether or not it had water damage, etc. My apologies for not being more clear about that. I just don't want you to buy the digitizer and then be upset because I told you to leap right in. In my humble opinion. A new one will probably take care of the problem. 90% if I had to call it.
I wish you the best of luck. And if you have any problems installing it shoot me a pm and I'll be glad to Skype or email to help you get through it.
Thanks, my Atrix never saw water. I just dissasembly phone for every single part and cleaned all socket with alcohol. Put back together but no result. I'll try replace digitizer with frame from ebay, it's risky but hope it will solve the problem.
Its the digitizer I'm 99 percent sure I had an identical problem. Dead zones and the phantom touches. Replaced the digitizer and problem solved. I believe the digitzer design is bad for our phone and is prone to this kind of failure

[Q] Screen troubles

So here it goes. I've had nothing but issues with screens on the G2. My first G2 had the glass separating from the frame during the first few weeks that I had it, then it decided to go into a boot loop randomly and Sprint replaced it.
My second G2 initially was fine but then of course the glass started separating after a few months from the frame and I just ignored it. About 8 months later I dropped and and cracked the digitizer, luckily I had synced my bluetooth keyboard/mouse to it and was able to back everything up.
I then ordered a LCD/Digitizer/Frame assembly. I installed it and noticed the frame and the glass were separating and I could see the back light like my other screens, this one also had some white spots and looked like pressure damage. The seller tells me that they accidentally sent me a defective screen (a "return") so they send me another one, which I notice has the glass already separating from the frame, at this point I don't really care anymore and just deal with the one I have already and leave the "new" one on the shelf.
About 6 months later a portion of the screen stops responding and sometimes will go crazy clicking and swiping everything. So I decide to order some 3M 3mm tape to properly adhere the glass to the frame of the "new" one I have on the shelf. I followed a guide and it all seemed to go smoothly, I let it dry for a week to make sure it won't start separating like the others. I tried installing it and while it looks great, the phone runs super slow, and touches respond after about 20 seconds. I unplugged the digitizer connections and it still runs super slow with my bluetooth keyboard/mouse. I plugged back in the connections and went into recovery and noticed it was just clicking everything and going crazy. I also noticed I couldn't power the screen off, I had to hold the power button down until the phone shut off.
I ended up putting my old screen back in and it works fine, other than the small portion of the screen that is unresponsive.
Any ideas? I feel just ordering a brand new phone, but I'm pretty sure it'll just have the same issue after a few months ..

What are you doing with it so that the glass separates from the frame? do you use a cover? could you post some pictures?

Nothing crazy. I use it and am typically pretty careful. I had my Epic 4g for 3 years and never had any issues with it.
First one did not have a case, I have had a case for the second one and it took longer to develop the issue.
It seems to be a pretty common issue due to the bezel being so small.
