Top of the touchscreen doesn't work - G3 Q&A, Help & Troubleshooting

Hello,
I think than since my phone fell, the top of the touchscreen doesn't work... I can't pull the drawer of notifications, except by changing the rotation of 180 ° ,but in this case, the navigation buttons do not work ...
Look the picture, it is a test of the touchscreen with an app
Thank you so much for help

Sounds similar to a problem I had with my G3 when I dropped it, only difference is that the glass screen broke too, sounds like a broken digitizer (I'm no expert, correct me if I'm wrong) to me. Only way of fixing a broken digitizer that I know of is by replacing it, cost me 130 euros at the time.

I had this exact same issue.
My battery failed me so I purchased an 'authentic' one from eBay, it swelled up and raised my screen, this raise then made the very top part of my screen (Exact same as yours) unresponsive. Problem went after I inserted a new battery and glued the screen back down. Might be worth investigating.

Touch screen problem after switching LCD

Hi,
a while ago, I cracked my Uni's LCD. So I ordered a new one including the digitizer, opened my Uni and swithched the displays. Now at times, the touch screen wouldn't work at all - unless I tap the upper left corner (the start button; in portrait mode) or the lower left corner (the left button or slightly above it; in landscape). After that, tapping everywhere works normally. Does anyone have an idea what this could be caused by or how to solve it?
Thanks in advance!
I'd make sure your contacts are very clean. If you think maybe they're not, then take out and clean contacts with dry cloth or contact cleaner and re-insert.
Also, make sure there's no debris around screen. That nothing is pressing on digitiser anywhere else that gives false postive for it.
enigma may be able to help you better, I think she's more accustomed to the HW
Generally, all touch problems are associated with a digitizer. Without actually seeing your device I assume your digitizer is faulty and the problem may be either improper adhesion or the soldering joint improperly formed. Adhesion problem may be resolved by warming the screen with a blowdryer, no need to get it hot, just slightly warm all over and smooth with a soft cloth as if you are applying a screen protector, it loosens the special sticky gel that attaches the digitizer to the LCD and usually helps in cases where sensitivity is sporadic or screen calibration returns wrong response. Check for any bubbling, although not seen when the screen is viewed directly, some may be noted at the angle.
However, in your case there are certain points that need to be pressed in order for it to work, so I take it, the screen works most of the time and the problem is intermittent, the corners that need to be pressed might be the ones where adhesion is not up to scratch.
Try re-assembly, if all fails - contact the screen supplier, faults can happen, especially in non-OEM parts.
Do keep us updated if you find the solution, I am sure all members can benefit.
Problem solved
Well over time, the situation changed so that the touch screen didn't work at all, unless I was pressing one spot above the LCD fairly hardly, at which time it worked without problems. Once I stopped presing the spot, it stopped working again.
So I tried opening the Uni and disconnecting and reconnecting the LCD FPC (which was located just under the spot that needed to be pressed), which seems to have solved the problem

[Q] Touch Pro 2 Screen calibration failed ?

Hi everybody,
I have problem with my HTC Touch Pro 2.
It was fully working until I damaged my LCD screen and digitizer.
So I ordered a new one LCD and digitizer from ebay. I changed old lcd and digitizer, booted up my HTC and everything looked allright. But problem came soon. Touch screen can't recognize my touch exactly. For example, if I click on something, digitizer solve it allways about 2-3mm higher. So I can't click on start, battery and every other click is moved about 2-3mm higher.
I made a calibration, but without any effect. I made a hard reset and than a calibration, problem still same.
And if try to make a new calibration (after first calibration after HR), I click on first cross (in the middle of screen), then up-left corner, down-left corner, down-right corner, up-right corner and nothing happens, I have to click on first cross again... and whole procedure again... So I have to make a HR and try to make a new calibration... still same problem.
Could anybody help me please? I'm going crazy, because I like my HTC and I can't use it anymore.
Is there any other way to make a calibration or how can I repair it?
ROM:
Energy.RHODIUM.29022.Sense2.5.Cookie.2.0.Jul.04.7z
(I have this ROM before I damaged LCD screen, any it worked fine)
It almost sounds like the screen/digitizer aren't lined up correctly... Just my .02.

Thanks for reply.
Ok, then It seems to be a HW problem between screen and digitizer?
So what can I do now? Try to repair it again?
How can I check, if digitizer is OK? or could be digitizer bad at all?

I'm just guessing from your description. I've never actually replaced the screen... If the two have to line up perfectly, I would ensure they are lined up correctly. Perhaps try slightly moving the digitizer down...

Ok, thanks. But I can't move with a digitizer, because it is in fixed position. Maybe I can move with a screen under a digitizer, but then I will not be able to see whole screen (digitizer has a black edge/margin/border).
Any other suggestion?

Nope, all I got. Calibration always works perfectly for me - if calibration doesn't work, there certainly must be some hardware problem. You replaced the screen, unfortunately you must establish where the hardware issue lies.
I don't have any help for you, sorry, just jumping on the wagon. My touch screen worked fine for a year but is now way off (1.5-2 inches sometimes) without having damaged the screen to my knowledge. I've switched roms (from MR.X to Mighty) and hard reset. If I try to calibrate it just keeps running through the process. Should I try to replace the digitizer? I plan on getting an iPhone if possible on Sprint in the coming month but would like to sell this for at least a little bit.
To both of you guys - have you ensured there's nothing between the screen or digitizer? Nothing that is wedged on the edge of the screen...?
I know some had reported complete screen failures just from some gunk that got wedged on the side of the screen.

Thought about that, but dismissed the tiny little amounts of gunk on the edge..currently searching for a toothpick or something small to clean out the edge. Thanks for the idea! Will report back.
Thanks so much arrrghhh! Found a small pin and got out most of the dust/gunk that was between one side of my phone. Apparently that bezel side is just a little bit looser. You saved me lots of time and money! Thanks. Always helpful on here and PPCGeeks.
Edit #2: Must still be more junk because the 100% functionality just went away. Time to clean it again

[Q] G2 Touchscreen problem

Hi. I just bought the G2 over the internet and I observed what I deem to be a touch issue. I first noticed the problem while using the on-screen keyboard, where an entire column of keys won't respond to touches, though when I go on landscape mode, they do. I tested the screen using doodle applications and found that a part of the screen stretching from top to bottom doesn't respond to touches [see photo embedded].
Are there any hotfixes/troubleshooting tips that I could do? Or is it really a hardware problem (e.g. broken digitizer) which requires repair/replacement? Having the phone returned means a grueling process of shipping and waiting, so I'd like to find out first if there's anything I could do from my end. Thanks!
I think that this is an hardware problem, I have this with my Xperia X1 too, but not so much
Sent from my chair.
probably need a new digitizer, about $20 from ebay, about 30min of your time. i had one that you could draw a line horizontally across the screen exactly halfway and the top wouldnt work but the bottom would. in landscape or portrait. new digitizer fix it

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!

No Display after dropping phone

Hi,
Unfortunately for me i dropped my phone and cracked my tempered glass in several places. gladly the screen underneath was perfectly fine after drop however, it has developed a fault as the screen won't turn on at all. I tried turning it off and restarting and although i can hear the boot up logo sound i see no picture at all. i can receive calls but cannot answer due to screen not displaying.
The screen had four main pressure cracks.... one is top left, one on the ear speaker, one bottom middle and one bottom left of phone. hopefully you can see it in picture.
Can you give advice on what to try or do to resolve this? will i need a new screen or disassemble to see what the issue is?
I've only had the phone for 2/3 months at most
Thanks in advance
looks like i will answer my own question....
i bought a replacement lcd & digitiser, one complete unit and swapped the necessary components over to new screen. all is working and good. not sure if the screen is repairable but there are other parts inside this screen worth selling on. it still has a non cracked immaculate screen along with the charging port and other stuff inside old screen.
at a cost of £70, i consider this an expensive fix
Thanks for the input kakawak
cheers
