Touchscreen problem left side - Sony Ericsson Xperia Neo, Pro

Strange thing happens to my phone from time
to time. About 3 to 4 millimetres of the left side
of the screen stops reacting to touches. I don't
think it's a hardware problem because when I
switch on auto rotation and rotate my phone a
bottom side of the touchscreen becomes the
left side and it stops register touches as well.

http://forum.xda-developers.com/showthread.php?t=1542115.
I remember many users reporting that they had problems unlocking their device - it took them up to 5 tries to unlock the phone. I've noticed that if I swipe the "dead" area multiple times quickly the touches get registered about once per 4-6 swipes. I guess it could be the same problem.
Anyhow This are of the touchscreen has been unresponsive for over 5 days now. I have formatted my system/data partitions and on a "clear" rom the area is alive again don't know for how long though. If the dead area moves with rotation of the phone and it's always the left side of the screen being affected whether that be the longer side or the shorter depending on the position of the phone then I guess It has to be software related problem. Am I right?
I could try to visit the service center but I don't feel like leaving the phone with them for the next weeks and also I, ve unlocked my bootloader via sony website so there is a chance that they won't even look at the phone.

Hmm it's pretty weird, i recall there being pretty much the same issue you have, but on MIUI. Contact your ROM dev directly imo or try switching the kernel. A very odd issue indeed....

Xperia X10 moist fingertrips touch response problem (ghost mode)

ever notice when your hands become moist...and when u r pressing an alphabet on the soft keyboard.after u release your fingers..the button will remain pressed or some totally different button will be pressed.
also once u press the keyboard, it will start pressing screen alphabets on its own?...as if some ghost has taken over control.
also..when hands are moist....and u try to unlock the screen or take the call...the slider wont respond to your fingers movement..and i have missed so many calls due to this.
just simple function was tapping on an app becomes so difficult as it ll open up some other app..
i am thinking it could be due to the default screen protector film provided from factory.
anyone with any other android phone face such a problem?
iphone 4 doesnt have this problem

It happens with and without the screen protector. I'm not sure if I have ever experienced this on an Iphone, or as prevelent as on the x10.
Any screen that relies on conductive tech will do this

havent noticed it on other phones.
including X1i ..the first xperia running crappy windows mobile.
i mean touchscreen does give problem with fingers are wet.
but here when fingers are even slightly moist..it starts acting unusable.
i am thinkin of changing the factory fitted protective film
Yea it does get really annoying... and then when it's cold, the warmth from your finger produces condensation on the screen, so I have to sometimes wipe the screen and my fingers dry before the phone's usable.
I agree, it is really hard especially when you press the delete key on your keyboard and erase everything!
I hope that this problem gets solved when multi touch get released, because the screen reception is handled different than now
That's why I keep a towel attached to the hook on the bottom of the phone.

Ok, the X1 was resistive, and under no circumstances whatsoever will wet fingers effect a resistive touch screen like this... Obviously if you use a resistive touch screen under water, you will have some problems.
Apple have been doing capacitive touch screens for a lot longer than sony, so they've probably got their act together on that... Mind you, this is of course one of the drawbacks of the capacitive screen - it will never be as accurate as the resistive versions...
I don't know too much about capacitive screens, but I know you could adjust the sensitivity on a resistive screen... perhaps there's an app somewhere... maybe

No use in removing the factory screen protector. Tried that before to see whether it improves the responsiveness, but it did either.
iPhone 4 also does have this problem and hence it's not related to phones, but it's their behavior under the given circumstances.
This is really annoying, missed so many calls and given up on typing so many sms's after starting over 3 times...
It's a pain when it's raining, and leads me to wonder if the new Motorola Defy can really function as advertised.
Still better than resistive, for me at least. My omnia screen is well knackered I guess because I pressed it too hard over too many months.

The most annoying thing is that I can't answer a call because the slider goes half way to the right and then it returns back to the left! Crappy screen! My finger are always wet, I didn't have such problems with other phones, especially the iPhone was awesome..
guys this happen with me only while my x10 is charging...but still confusing i'm totally disappointed from SE because of many things the battery performance and so many things....
I wonder if there's a way to make the menu and back buttons act as red and green buttons on traditional phones?

Xperia Mini Pro Capacitive Button Problem

Hi I was wondering if anyone has the same problem as i am having right know.
I have a Sony Ericsson Xperia Mini pro White SK17I. It was working well untill when i tried to press the back button. I had to wait for so long to get a response from the back button. I tried the same thing with the menu button (Not the physical hone key) it still had the delay. The delay is about 5-10 seconds. Sometimes, you have to wait extremely long or you have to press it again. sometimes it runs normally. But rarely it does work as normally should. I only had the phone for 2 weeks. I was wondering if i can exchange it since i have a 12 Month warranty. thats all the problem I'm having right now
thank you
Me too but not always i discovered that it depends on memory usage.
Sent from my SK17i using XDA App
me too..need to press harder..but not usually like that..most of the time, it works normally.
same here..just to make a point, did you have the noise problem as well?
I have the same problem. I think has to do something with the temperature/humity. If its warm outside and i have sweat on my fingers its happens, when its cold and dry everything works fine. I tested with /dev/event/input and with wet fingers it does not even trigger any events.

I got this problem right after installing NFS Shift. Now the back key often doesn't work and the Options key is unresponsive.
It is a known issue related with temperature, affecting more and more people every day (including me). SE is not responding, but seems a design problem:

my back key is okay, only menu key is unresponsive at all. i think this is because of hardware problem.
i bought it 1 day ago, though. gonna bring my phone to SE service center tomorrow.
Guys I fixed my problem. This guy on facebook had the same problem as I did. He fixed his and so did I. The reason it lags isnt because of the memory usage. Its some other reasons that I dont remember. Anyway, if you guys still need to fix yours, heres how. First you got to have cottons and a screen protector. The Sony one that you get from the box works. You have to apple one TINY drop of soap onto the cotton then wipe it over your display. Make sure you clean the buttons cause thats the priority. Make sure you cover the top bits. After you done that. Get your clean cotton and wipe it to get the soap out. DONT USE WATER. After thats done, make sure there is no string of cotton left in your screen. After you checked, apply the screen protector then its done. I just did mine today and its going well so far. Trust me guys this isnt a trap to break your phone or anything. I trusted this guy that told me the steps and it worked. What I am trying to say is just give it a go. If you did it like I did, I think you should be fine. I love my xperia again hope it works for you guys

I have no back button issues so far. I once had it slowing down but that was related to an application hanging so low memory might be related.
No problems here so far, but it seems like german phones don't have problems at all. Ive been checking amazon ratings all day long but no1 ever mentions problems with the button
Well some people have the problem. I just wanna help them.

Yea thats nice My guess is, some countries get worse quality phones :/
As far i have the phone the back and menu keys work very fine for me, in fact they are very sensitive... and works fast
I had no problems until the update to Android 2.3.4.
Now I can't even play a game for 10 minutes and it presses the back button a lot.
It looks like it can be related to the firmware.
-----------------
I've seen on another site that other people also are facing more heating after update to 2.3.4. Well, since overheating is related to the issue, it may be possible that it is causing the back button issue for me.
Its Due to Memory Blocks aswell
The Problem is mainly due to too much of moisture in your hands...
to get rid of the problem, wipe off your hand of all moisture, and clean your cellphone screen and the buttons with a soft cloth.
And also remember to clean the used memory. usually its both the problems occurring at the same time, due tio which it seems no to be working..
hope it helps
I've had this problem too and I found out that the cause is the sweat from my hands.

I beg to differ, but my German Mini Pro does have the back-button-issue!
Don't know if it's due to sweaty fingers, I'll try one of these capacitive pens some day.
But I can say, as soon as I plug in the power cord, the button is working again.

Xperia Xperia Mini and Mini Pro have the worst touchscreen ever seen!

Hi guys,I bought a Xperia Mini Pro to my girlfriend.
Like my Xperia Mini has the worst touchscreen that I ever seen/touched.
Try to play Fruit Ninja is impossible,because the touchscreen lose your fingers.
If you draw a circle very fast with a paint app,it's lose your touch.
This is annoying when I navigate on the browser or scroll contacts and music.
Why no one has noticed this problem?
The only problem on your list that i noticed is with fruit ninja but the weird thing is that it's working well with the other app called fruit slice
That's the only problem i noticed about the touchscreen in 2 month of use (sk17)
otherwise I am quite satisfied.
I have Mini Pro (SK17i) and I still get nearly 1000 points in Fruit Ninja (Arcade Mode), not too much but I think it's not bad at all.
I advice you to download "Multi Touch Paint" and you will discover how malfunctioning this touchscreen.
Use this app in "Kids Mode" and made a continuos circle very fast.
In Xperia Mini there are some disconnects.
In Xperia Mini Pro the touch screen is crazy,because the pen is going where don't touch.
I dont know why are you having hard time with screens, but my Xperia mini works perfect, never had any problems with it

I send it to Sony Ericsson Support,I hope that they can fix it.
Using an (constantly under RAM pressure) X8 at the moment I unfortunately have to agree that touchscreen responsiveness is noticeably inferior on both the mini and the mini pro. I noticed when using the device one handed, i.e. operating the screen with the thumb. Fast scrolling is nearly not possible. We're not talking about performance here, the device ist fast. It is about the digitizer being unable to register quick flings over a short distance.
To visualize this I tried Kids Paint Free. It simply draws gestures with random colors for each stroke. This is perfect to determine whether the digitizer has lost the finger: if it has, a new color will be drawn.
I drawed a couple of QUICK vertical up-down flings of about one inch length each at about four strokes per second. The X8 registered these correctly and displayed them at the given length. The mini (and also a mini pro I tried at a local store) registered only at most half an inch of the movement. If you increase gesture speed even further, some are being registered as taps (resulting in a dot being drawn)!
This is exactly what happens when scrolling around: it feels laggy, because you can't input a certain length of fling in a short time, i.e. "give power to the scroll". Occasionally you might even end up with a false tap where you actually wanted a scroll.
Another test is to start on the upper right corner an try to fill the whole screen by diagonally wiping to an fro until you reach the lower left corner. This will even end up in the digitizer not responding until you lift the finger again. It was not possible to fill the screen in one long gesture! Again no problem on the X8.
I returned my mini yesterday for this very reason, it renders the device unusable to me. A real pity, given the otherwise good specs of it.
Now: have I encountered defective devices? Can anyboy confirm? Is there a parameter to set some kind of progression like with mouse pointers on a PC?
You phone might have problem with heating and navigation keys. Keys are connected to screen, so every time you hold you finger on the screen, keys may react by themselves. Send it to service if you have warranty.
Its very strange that you have screen issues... I have sk17i and also try st15 in store. Feelings just awesome,
sensivity and speed is very good. No lag or stucks at all time. Maybe you sould return that one for warranty

Touchscreen responsiveness Xperia Mini (Pro)
Hi all,
thank you for your input. Please don't blame the thread title, I didn't choose it and just didn't want to clutter the forum with another thread on the same topic.
Just for the right scope: my Mini did not overheat in any way, the two soft buttons worked perfectly. Also I'm not complaining about scrolling performance of the OS or the device. Once it scrolls, it does so smooth, lag-free and fast. I'm all about giving drive or momentum into quick (respectively short) strokes.
Please find two screenshots made with Kids Paint to illustrate what I mean. Sorry that I may not yet post image links. I'd be glad if anyone who is content with his or her digitizer performance could try the same on a their mini (pro)s. The APK is also attached.
Test case 1 (vertical flings):
Speed is absolutely of the essence. This screen has to be drawn in less than three seconds. There's no point in doing it slower, it will work. On the Minis I tried it was not possible to get the lines that long in the given time.
Test case 2 (screen fill):
Start at the upper right corner and fill the screen in one continuous stroke. Again, this has to be done in at most five seconds. I have not been able to do so, the Mini's digitizer lost my finger (new color drawn) and stopped completely reacting at about 3/4 of the screen.
I'd happily accept that I had devices from a defective lot and try another. I wouldn't invest time here on this issue if I didn't think that the Mini was THE phone for me (price- and spec-wise).

touch screen issue

I just bought a archos 101 g9 when it was on sale on woot last week and so far it is working pretty good, however I have an annoying problem with it.
If it has been sleeping for over a few minutes (regular sleep, not the deep sleep) and I wake it back up the touch screen goes crazy. The bottom left corner keeps detecting a touch event. It will cycle from multiple on/off touches a second to one on/off every few seconds. If I rotate the tablet to portrait, it will start scrolling the screen none stop to the left. So far the only fix is to do a reboot.
It does not happen every time, just occasionally when I wake it up from sleep.
Today i got a case for it, and whenever it is in the case, the touch screen goes crazy. Same touch events in that same area.
I am guessing something is wrong with the digitizer. Anyone else seen this problem before?
Have the same problem, and as I've read on xda and archosfans forums, this isn't an uncommon issue. We'll just have to wait for a firmware update, as rebooting seems to fix it, so it doesn't seem to be a hardware problem.

I have exactly the same problems.
@ARCHOS: PLEASE FIX THIS PROBLEM. THIS IS A SERIOUS BUG !
Sensitive Touch
I have similar problems with the touchscreen. If I'm holding it with one hand by a corner, it detects touch. The rest of the time it is a little jittery and releases or double taps in games. It's still not a deal breaker, though.
I hope we don't have to swap digitizers to fix it.

I'll give that a try and see if that works. I just got a case and as soon as it is in the case it is even worse.
EDIT: I installed a calibration app on xda and it really made it worse!
What app are you using to calibrate it?
I have a similar issue sometimes.
For me the fix is simply to clean the screen.
The strange thing is, it happens even when the screen doesn't appear to be especially dirty but I put the tablet to sleep, give the screen a serious clean with a microfibre cloth and the touchscreen issues vanish.
Could be a different issue to what you guys are having but the symptoms are the same and it's an easy 'fix' to try.
Hope it helps.

Thanks, I had not noticed that area in the settings before. Recalibrating it in the cover has helped a lot.
I pretty much had this since day 1......
The current state is ; it doesn't work at all then all of a sudden It will pop back into life and then pretty much go "mental" as already described, I also found it reacts poorly to minor temperature variations, i.e going from outside to inside and general day to day travelling. Recalibrating used to "help" but now has no effect.
From watching the debug logs part of me thinks it's a bit of both, hardware and software ( just a hunch ) I noticed the driver fail to get a "ping" response from the hardware a couple of times.
I've pratically given up on it myself and plugged a keyboard and mouse in via a hub on the full size usb...... The hub has now stopped working for some reason , I'm now on a OTG Keyboard with a Virtual Mouse Driver using the numeric keypad and some adb input trickery ,
I've got another touch screen/digitizer to plug in, just not got round to putting it in yet and a little part of me is starting to enjoy finding more elaborate ways of interacting with the device... :laugh:
Does anyone know who the OEM of the digitizer Unit is? My previous investigation led me to china but information seems to be thin on the ground with this one

If all white that's mean your LCD is good,maybe try flash another ROM or factory reset.

Sounds like you're having the same problem as me. You only have a single line though, while 2/3 of my display is like this. Mine gets like this whenever it's a little under room temperature, and it's a hardware defect according to Sony.

My XZU has this 1x1 cms 'purple cloud' at top mid center of screen all the time. I see it at the phone boot animation also. Its not captured on screen. So I guess its an LCD burn mark

Just checked out your video, and i'm having this issue too. That's called "ghosting", and that means that the response time of the screen has gone to hell. The issue gets triggered on mine when the temperature drops a little.
Try this:
- Is it functioning normally in room temperature? If yes, put the phone in your refrigerator for 2-3 minutes and see if it's still functioning properly. If not, well.. then you're having the same issue as me, and i've talked to Sony, and it's a hardware defect and you'll have to use your warrenty and get a new screen. I sent mine in for repairs today, so i'm crossing my fingers.
IF you decide to send it in for repairs, remember to call them and ask them to do whatever triggers the issue, or else they'll simply re-flash the firmware and call it a day. That's what happened to me the first time, and you don't want that to happen

Alright, so it's the same issues as i have, and it's a production error according to Sony, so you'll have to send it in for repair. This is strangly enough only the second case where this happens, that i've read or heard about (including my own Ultra), so it doesn't seem to be that big of an issue. It could simply be an issue on a batch of Ultras that we got. It's a really strange defect though.
Alright, so I got my Ultra back yesterday with a new screen, and the problem is solved. I tested it by leaving it in my refrigerator for about 5 minutes, and there were no signs of slowdowns or other defects, so that's the way to go
