Hello,
I have been using a trusty U8120 for a while now with Fresh Zodiac Fruit Rom. I was browsing on it last night and then next day the screen was just inoperable. Sometimes it would "take" some input, but it would understand something different (e.g. on a keypad, touch it in the middle "5" and it understands top right "3", but then again, "3" doesn't register either).
Here's the funny thing: it doesn't take any input whatsoever, but, if the screen is about to idle shut down and I touch it, it goes back on full light, meaning it understands the touch.. what the..?
I tried reinstalling the firmware but nothing happened.
I have confidence in opening the phone up as I have done it many times before, but I just don't know what I should tamper with in hopes of fixing it.
Any suggestion welcome. Thanks in advance guys.

Did you ever get a solution for this. My phone just started this as well

I have a T-Mobile Pocket Phone Edition,
It's had a rough life but as kept going for over 3 years now.
For the last year I would have to realign the screen 2 or 3
times a week but over the last few months it keeps getting worse.
Sometimes the screen won't respond to anything anywhere,
then after I tap it a few times boom works fine.
Sometimes I'll tap on the “Ok” and the “Start menu” will activate.
Sometimes drawing a line up the center of the screen will end up
shooting all over the screen.
And sometime it will work perfectly!
I thought the problems were to erratic to be hardware so
I hard set after awhile it started again,
So I hard set and installed a different ROM after a coupe hours
the problem was back.
Also sometimes the align program will get stuck in a
loop that doesn't end.
I've searched but can't find an answer? Anyone have an idea?
I've already taken it a part once but couldn't see how to get
any further after I toke the back panel off? Please help!
WOW nobody? So no one was heard of this problem before?
Can anyone direct me to directions on taking apart the Wallaby?
Thanks <><
It's a problem with touch screen. You should check (and fix) it.
Maybe it is necessary to press well screen to the motherboard. (Sorry my english).
Ok, Can you tell me where that connection is?
Thanks
Toke everything apart, found the connection, cleaned everything (w/ screen wipe)
put it all back together. Still have the touch problem and now the backlight won't work!
I've found if I press the unit in my hand the touch panel works right,
I don't think it's a lose connection to the main board so I think it must be
one on the main board.
If anybody thinks they want it for parts let me know! :?

BEFORE YOU RAISE YOU QUESTION,
1. did you make a search for an answer yet?
2. you need to provide details for you problems inorder to let other seniors here to help,
for example... which rom, how is the history....what had you done to it.......
ok ?
[QUOTE=..................
the same problem (i think it is the same) here..
it occurs generally while i am playing games and typing so many letters for sms's.
the problem has been existed since i have bought my prophet. the problem was there on official wm5 rom. using wm6 or 6.1 roms didn't fix it, but decreased a little (or i quit playing games so much).
since i couldn't enter the pin to unlock, two or more times i couldn't make an urgent call, then i soft reset it..
i thought that it is affected by heat changes when the battery consumption is high or when i hold it in my hand very long time. i also thought that it is a hardware problem, but not sure.
recently, i do not use my prophet so much, then it hasn't annoyed me for a long time..
sory,
i should have defined the problem mentioned above:
- when i touch a point on the screen by stylus (or any other way)
it assumes that i touch some pixels left of the point i intend.
- in a few minutes, sometimes this shift increases about one or two centimeters, sometimes it stay one or two letters left of the intended letter on a standard keyboard.
- this shift is much more on the right part of the screen, it gradually decreases towards the left side, and finally it exact macthes that your pressing point.
think of a rubber band, fix one end onto the left edge then stretch it to the right, this is the touch screen you see. release it to shrink it, now this is the way that it assumes you touch on it.
- after soft reset, generally the problem's gone, sometimes not.
- after re-aligning the screen, it's gone, but when somehow the cause gets remedy after a while, it occurs reverse way, then you should correct the screen alignment again (
screen misaligned
I have the exact same problem for years, I would say ever sice I got it. It's happens just like atakatas says.
Just something I noticed, It happens to me when I keep it in my leg pocket, and usually I don't soft reset nor realign the screen. I used to do that, but then I found out that waiting a few seconds it would get back to normal.
So I never asked anything arround here because it really didn't look like a software problem. I would say it is climate sensitive
Cheers

Just to be clear, do you mean that your phone doesn't register your fingers touching the screen on the left side of the phone sometimes?
I would suggest downloading the free app "Touch Test" which shows a grid that not only shows where you are touching, but the path of your slides across the screen. If the phone begins to act up again, you can open the act and see if and where the screen is cutting out in the grid. Aside from that, it might simply be that you need a replacement and its coincidental that it was acting up along side you running a 4.0 rom.

That is the oddest thing I have ever heard lol
It really might be a hardware issue man...I can't think of how it could be the rom. I mean, sure you might occasionally
have an unresponsive touchscreen....but only half the screen working?? That's just weird Oo I'll keep looking around for answers though man
but thus far I've found very little.
Good luck

I have a video but i'm new member i can't send link to my post. I will sent to your inbox. tk
Okay, so that anyone else that happens to come to this thread is on board, here is the video that shows his problem:
http://www.youtube.com/watch?v=5xDolJhmDog&feature=youtu.be
As you can see in the app, if the origin of the trail is on the right side of his screen, the swipe is recognized across over to the left without problem...if however the origin is on the left side of the screen, no touch is recognized until he reached the middle of the screen, at which point it becomes recognized.
I am still looking around for a similar problem, but thus far have few ideas. Typically, the screen either is totally unresponsive or momentarily unresponsive...never half and half, and especially with such weird rules. By this, I mean that obviously the left side of the device is capable of recognizing touches, since if he begins at the right side, it does just fine....the only problem is if he originally touches the left side, then it doesn't recognize it.
My guess: it could be a kernel issue.
I would try the following:
Pull battery and reboot. Take out any external SD card.
Back up what important apps or data you have and try a factory reset.
You can also try some the options below:
1. Reflashing the kernel.
2. Try a different kernel if available.
3. Factory reset and full wipe and flash a different ics or cm9 rom to see it the problem persist. You can try to isolate the issue to hardware or firmware.
4. Full reset and flash back to complete stock to see if the problem persists. If you are fully reseted and back on stock eclair or froyo and the problem persists, you may have to open up the device to check all the connections.
sometimes a bad battery may also creates some problems
Now i'm using xerxes custom 2.3.6 gingerbread. It's ok but i don't know why when i use ics. I can use half left screen

Hello mates.
I've got some issue with my desire x touch screen. It is becoming unresponsive.
The whole thing started like 1 month ago. I've noticed that as my phone gets hotter (playing games, using internet) my touchscreen was slowly becoming unresponsive. Firstly I was unable to scroll down my notifications (only the narrow bar at the top was not working) and then it came to a random places of screen, so I couldn't even write sms message. The thing is that it is not unresponsive at all. When I press certain unresponsive area it finally detects the touch. I tried everything, from wiping my screen with a soft tissue through removing battery and sim and sd card to wiping dalvik and cache. I've noticed, that after night the problem was almost gone. And again, after using phone for some time issue occured again. I figured that flashing a new kernel might be a good solution. And it helped and I was happy.
Unfortunatelly, yesterday problem returned. But as you probably suppose - flashing kernel ain't helping. I've also tried other methods mentioned above, but the only thing what helps a bit is leaving the phone unused for like 1 hour or so.
Do u guys have any ideas, what can I do to repair it or to fix it? Any help will be strongly appreciated

I have a similar problem after replacing touch screen. I have found the source of the issue, it could be similar to yours.
My touch screen at the bottom was glued to the LCD in a short line and the adhesive was probably touching part of the LCD cable that goes underneath. I used a hair drier to warm it up and lift off the touch screen. That way there is no bad interaction between the touch screen and the LCD. Haven't had this problem since but my touch screen is unfortunately a bit lose this way. Even now, whenever I push the navigation part of the touch screen too hard, the problem comes back. I will need something to isolate the bottom part of the touch screen from touching the LCD. I will keep you updated if I find a final solution. In the meantime, it could be worth trying it on your phone too.
I think I will just get S-OFF, revert my phone to stock and give it back for warranty repair Anyone of you guys did this? Did 7 vibrations at boot void your warranty?
I'm thinking about warranty repair, cause my bro has the same phone, but full stock, not even rooted. And he got simmilar problem to me, but with less intensivity (it just comes and goes once in a while). Also recently I got this phantom touch problem (after enabling show touch in options I saw my phone is detecting some touches in specific areas) So I think warranty will be the only option :/
Hey guys,
I got my Redmi note 2 yesterday and I'm having trouble with the touchscreen. sometimes it seems to be perfectly fine and sometimes it doesn't react properly. It seems to be worse in the right half of the screen. Sometimes I start scrolling and it works fine in the beginning, then the screen stops detecting my finger and when it detects it again, it opens the thing that my finger is on instead of scrolling.
I'm not sure if this is a hardware of a software bug.
Would calibrating the screen help? If so, whats the best way to do that?
I would usually try flashing a clean stock rom (the one it came with has some bloatware anyway) and test if that resolves the issue, but that's probably not the best idea if I decide to return it.
thanks for your help

Try entering in the MTK Eng. Mode, then go to Hardware Testing->TouchScreen->HandWriting and try drawing some lines crossing the point where the problem occurs.
A friend of mine had a Nexus 5 with a malfunctioning touchscreen, doing a similar test we noticed that there was a full horizontal line where the touch were not detected so every vertical line we were trying to draw were broken on the point where the bad line were crossed.
Obviously in that case it was an hw fault.
EDIT:
Reading your post again, it seems a behavior caused by lag, so maybe it's a sw problem and not an hw one, especially for the fact that "it opens things instead of scrolling".
Does it always happen in the same point/area? Or is it totally random?

I already did that and the results are very inconsitent. When I first tried it, it started drawing a line as it should, then it stopped and started again half a centimeter later, then it stopped again, and it pretty much went like that from top to bottom of the screen (at least on the right side of the screen, the left side worked better).
When I did the same test again, it didn't even draw lines, it just highlighted a few single pixels along the way that my finger was traveling.
And currently everything works perfect and smooth as it should.
It does kind of feel like a software-thing, but in my mind (correct me if I'm wrong) that should affect the complete screen equally and it just doesn't. I tried pulling down the notification bar earlier, from the top right of the screen and it just didn't work. I did a few tries and nothing happened. Then I tried pulling it down from the top left and it worked fine.
As I said it works fine at the moment, but I guess I'll make a few screenshots and a video of the problem, when it occurs again.
Ok, so the problem came back and I was able to do some more testing and make a video (sorry about the shabby quality, but it'll have to do ).
youtube . com / watch?v=rKsponNr9lA
As it turns out, the whole screen is affected equally, so I'm pretty confident that it's just the software but I'd still like to hear a second opinion.
The thing that kinda throws me off is that the reboot didn't help at all...
So what do you think? Is it just buggy software?
I'd try contacting the seller and explaining him the problem.
Maybe he will ask you to flash a new rom to be sure that it's a hardware problem and not something that could be solved without a replacement. That's what happened with my first phone from China.
If not, you could ask him and I think he will authorize you.
