Anyone else getting the ghost touch problem?
I couldn't work out what was causing this on my phone so I enabled show touches in the development menu and it shows.
It goes from 2 to 3 spots on the left hand side of the screen.
It's not a major problem but happens at least 3 times a day and won't snap out of it unless I put the phone back into sleep a couple of times.
Do you think maybe scratches on the screen cause this?
TIA
Is your phone connected to a charger when this occurs? It might be it, since im experiencing the same thing since htc desire hd.

No. Can happen at anytime. Quite random.
It takes a few on and offs with the sleep button to stop it.
Can't get off the lock screen until it goes away because I can't move the unlock slider.
Very annoying.
I had the same problem - the first day i got my hox. With and without the charger (with charger a litte bit more often i think).
I pushed the complete left side of the screen (top) carefully and now it works well. No more ghost touches ^^.

Ok. Once I pushed around the screen edges, the left side has some play and moves maybe a mm with a slight creak.
I push it in but still that little bit of play on the left side.
It's quite impossible to show the service centre the problem because its so random but now I can show them this.
Cheers.
I hope you'll get a new "perfect" hox and i'll not have the same problem later :fingers-crossed:

Hi
I upgraded to my new DHD less than 3 weeks ago. It is not rooted and I did the recent OTA update over Christmas.
Over the last couple of days I have started to experience difficulty unlocking the device on the slide-to-unlock screen. The problem seems intermittent - somethimes it will unlock fine, and other times the slider just seems to "get stuck" at the bottom of the screen.
At first I thought this a bug or something, but after some investigation I am concerned there is a problem with the digitiser. I opened a picture and zoomed in to fill the screen and tested the touchscreen in different places by sliding the picture around. What I found was that the bottom 1cm of the screen above the keys does not respond properly to Up and Down swipes. It is fine however with side-to-side and also individual taps. This is obviously a problem when trying to move the unlock slider!
I've had a screen protector on for about a week - I don't imagine this has caused the issue but haven't removed it to test as yet as I don't have a spare. Aside from this, the device has been very well looked after, definitely no bumps etc and kept in an HTC leather pouch.
Any ideas? Should I return it to CW?
Thanks
OK, I seem to have resolved this for the time being but expect the problem to return.
I downloaded a screen test app that allows you to draw on the screen and got some very strange results. A 1cm band of screen about 1cm up from the bottom was completely unresponsive. Trying to draw a horizontal line within this band would result in lines being drawn either above or below it, or strange vertical lines "jumping" around. The rest of the screen was fine. I realised this is why I have been struggling to close the keyboard - the button is placed within this band and trying to press it would result in on of the buttons above or below being pressed. Also have had problems with the sapce bar.
I did a restart (not fast) and this has resolved the issue, however I expect it may return as I did a restart only yesterday.
At least it is obviously software and not the digitiser....
Hi again. As expected, the issue returned after a couple of hours. This time however, restarting is not making a difference.
I resorted to a hard rest, which has not changed anything either.
Any help/ideas would really be appreciated...
Best to return it for repairs or exchange. Seems like the digitiser is faulty.

I agree, this definitely sounds like a hardware problem.
Hello all! Ive just recently got my Xperia arc, and flashed a nightly build of CM7 on it, number 20. Everything seemed to run smoothly, but just now screen started to behave very weird, it almost seem to have osme kind of "ghostly" second touch.
The upper part of the screen is almost impossible to use, when I try select an app to move it on the screen, by holding finger down, it just flickers for a second and gets deselected. If I manage to select it and drag+hold, it starts spazing out all over the screen, with screens switching between eachother by it self.
The problem is especially noticeable in games, where you usually have a joystick controller in bottom left corner. When using it, I usually trigger the buttons above it in the upper left corner which I am no where near at with my finger.
Is this a ROM issue, or hardware issue? Ive been using the rom for couple of days with no strange to it, and now this happens. Any ideas what the source can be?
ROM failure.
Sorry for bump, but apparently the problem remained. I changed to XDA rom, which too is based on CM7 thou and after a day I stumbled upon same problem of ghotsly second touch on screen.
I cant hold to move apps, cant precisely press a button in game on left side of screen, it then triggers some other button nearby. I do get haptic feedback from long press on a homescreen, but the "add new" menu popups only every few tries Any ideas of what may be causing this? I would really like to avoid the hassle of resetting the phone and sending it back for repairs :/
try stock one or miui.
It sounds a bit like your screen had a bad encounter with water...
Could this be the case?

No, this phone is only few days old.
I think I am noticing a pattern.. screen behaves this way only late evenings, till next morning. I never noticed the issue during the day, but then it was there again for no reason after I left phone for couple of hours (it's past midnight here at the moment). Now when I think back, same was previous two evening, issue only noticeable during late evenings. Could my phone be possessed lol?
It's quite weird issue too. Upper half of the screen seems to have a ghost touch as I said. When trying to add a widget to upper screen, I only get a haptic feedback from long press. When playing games, all buttons on left side (landscape mode) get activated as soon I press one of them. Most weird of all, is that screens works perfectly in app drawer and settings, but not in app/homescreen. I will test how it is again tomorrow and report. If it works just fine again as if nothing happened I will be really puzzled.
Currently on CM7 Xda version, same was for official version. I am considering updating to MIUI, just gotta figure this radio difference stuff, but am becoming sceptic to whether this issue really lies with ROM and not app/settings.
Yep, issue is gone like nothing happened at the morning, this is is haunted ._.
I've figured the cause, it only happens when the phone is plugged in and charging. Beats me why thou, what remains to see now is if it is tied to the kernel or not. Posting it here in case others with similar problem stumble upon the thread.
Are you using the stock charger, i used to face bit similar problem when i used to connect my old HTC USB charger... later i discover the HTC charger was giving only 500mA , where as sony one is rated at 700mA.

Thanks for the tip! Turns out it didn't like my 1000mA charger I am using for all my usb stuff, but the stock on works perfect (it's 850mA).
hey there guys and girls,
This is my first post and was just wondering about my xperia plays touchscreen. I bought it almost a year ago and since i got it the problem has been occuring. Its not major dont get me wrong but it can be really annoying when i am texting my frineds. What happens is that i will press a letter then it will just decide to press a bunch if other letters next to them. Also the keyboard will randomly go down so ill end up clicking send and completely wasting a text.
Any help would be great... Thanks xD
Large fingers? lets hope its not a digitizer problem but you did state its been happening since you got the phone. the xperia play does seem to me to be more sensitive to the amount of pressure needed or not needed; or is it just me?
Got used to using swype keyboard on my sgs and haven't used the stock keyboard on the play.
you could try to clear data for the keyboard Settings>Applications>Manage Applications>All>"keyboard"
maybe another keyboard will solve your problem entirely, there are plenty of them on the market/store.
this is just one as there are many
https://play.google.com/store/apps/...xLDEsImNvbS52bGx3cC5pbnB1dG1ldGhvZC5sYXRpbiJd
edit: forgot to mention, if you install this or any other input method you will first need to enable it in Settings>Language & keyboard>"keyboard"
just tick the box next to the keyboard and it will give you a prompt; read>OK
then say in messaging just press and hold on the text input field and select input method>select keyboard you want to use
also, when your keyboard disappears for whatever reason or doesn't show when needed you can press and hold the menu button for a few seconds to bring your keyboard up or make it go away.
I pulled off the screen protector and that seemed to fix it for me.
i've been having the exact same problem, it seems to occur mostly when my phone is charging or when it's too warm. Didn't bother sending it back though, but yes, it can be verry annoying when trying to text
Don't worry, its a standard Sony Ericsson issue. Usually occurs when the device overheats.
Reboot or look into ROM flashing and the problem will be resolved

Mine does that when there's moisture on the screen, or when plugged into the charger. I've found typing to be much less annoying in wet conditions when using Swype.
Dry off your screen often enough and it should help. Removing the anti-shatter film (which is next to useless anyway) also makes a difference.

Welcome to XDA!
Try solutions posted above.
If You ever need to test any piece of hardware on your phone, try accesing serice menu by typing this code in Dialler:
*#*#7378423#*#*
From there You can access Service tests menu and test Your Touch Screen/Earphone/Display just to mention a few.
Also screen protector isn't any good for me, standard keyboard is too small and stock firmware is to laggy to type messages. Solution is easy if You are ready to give your phone a boost by flashing it as mentioned by someone else above.
Wow, there is a great amount of different anwsers
I remember that someone on these forums said that Xplay has problems with multitouch regonizing (or something)
Basicly, the touch points wont reset unless you do something (i dont remember what)
Personaly, i just press powerbutto to "shut down" my screen, press main menu butto and open the lock, its all back to normal
EDIT: wait few seconds (like 5 or so) before you reopen the screen
i'm having a similiar problem, i charged my phone with 5v a couple times, so the last week, the touchscreen doesn't work. sometimes it does, it has been abit tricky. it like works sometimes, with an effort of constantly mashing the screen (with swipes and presses), but the last 24 hours, it's been practically dead. every other part of the phone works, like LED, pad controls, speaker, etc etc, just touchscreen is dead... any solution, methods?

Honestly, I have no idea. I just know that the digitizer is what makes the touch screen work, and that there have been xda users buying them for replacement parts before.

I have been getting this problem when coming in from outside. I can hold my finger about 1cm above the touchscreen and it will type random letters as well. Seems to be affected worse in bottom left hand corner for me. It settles back down after a while of being indoors. Its really weird though.

That's because the difference in temperature and humidity causes condensation to gather on the screen, temporarily. Capacitive touch screens work by conducting electricity, and moisture is conductive.

Ahh, I see. That makes sense. I took the factory installed screen protector today as well. I'm hoping this will help too.

Hi guys. I know many of you have had touchscreen problems and whatnot, i searched but it seems like this one is a bit different from usual. Yesterday the phone was totally fine; i woke up this morning and it had a lot of touchscreen problems: at first it registered touches without me doing anything, but after a couple of reboots it was just unresponsive. After another reboot and some messagging, the problem reduced to a strip on the screen simply not working. The strip is located exactly where the first notification on the status bar is (like when you receive a message and you click on that notification). I have the trueancestor stats bar buttons, so that zone is a tad more down than usual. Anyway, all I did yesterday was a quick game. I think it may be the flex cable not working because of the sliding, but it happened all of a sudden, not gradually. I must say that some weeks ago I had the same "registers touches by itself" issue when typing, but a simple reboot was enough. I tried doing factory reset, but nothing so far. Also I can't use pc companion to flash everything stock back (I unlocked bootloader months ago, even though I relocked it; I dunno if it's locked or not right now), and I can't seem to find a working flashtool download link -_-. I don't think that would help much, it probably is a hardware problem, but who knows. I'm on true ancestor 1.6 LE, stock kernel.
Any help would be great, as I fear the phone will get refused in assistance because of bootloader unlocking.
Did your phone had contact with water? When my screen had contact with water it registered touches randomly.
it didn't. it has a screen protector anyway; but that's not the problem for sure. it doesn't register randomly, simply a strip doesn't work now...
Hardware problem. Could be flex cable or digitizer.
Today there were two moments it began to work again, but a few minutes after each one the problem came back. Sigh...
Mine does that when the screen is moist or my hands are too oily. Are you sure you're working in a dry environment?
mhh... exactly that? I dunno, my hands are dry and i think the screen is too; it has a quite thick screen protector (the skinomi one), so even if it got moist that shouldn't be a problem, right? I'm now living in a different town and that may have changed something, but the problem didn't show up until now, and it was sudden.
Also, I noticed that using gamekeyboard on a certain profile I had buttons placed on the strip, and pressing hardware keys mapped to those buttons actually works. This restricts the problem just to the actual finger-touch-detecting mechanism. Does anyone know anything about this?
Edit: lol I heated the phone up a bit with a hair dryer. It works now. I hope it will last and I'll not have to do this again over and over
Just as i was expecting the OTA update something more serious happened this morning to take my mind off the update.
To cut a long story short I dropped my HOX on the side walk.
The phone landed on the bottom so appart from a tiny scratch in the lower right corner of the plastic no other problem or so I thought.
I unlocked the phone and everything looked fine.
Then I put it back in my pocket but thaught let me check the side rocker key as well.
To my surprise HOX was off and would not turn on.
I came back home and connected the charger and suddenly the phone started working BUT the brightness of the screen is really really low.
You can barely see and some times brightness (even this low one) is lost completely or it flickers(the brightness) up and down.
I checked the brightness controls and they are all as they should be.
I suspect that the battery probably is causing this and the HOX will have to take a trip to service but I was wondering if any of you guys have any ideas to avoid this.
Thanks in advance for your time
Well if you are very good with opening up mobile devices I would give it a try and see if there's any loose connections.
On the other hand, i've never opened a phone and if I were in your shoes I would probably just send it in for repair so you'll know that it'll be fixed for sure . No joy in risking your warranty and see that something else is wrong in your device..

It's FAR more likely you've damaged the panel behind the exterior, very likely the backlight itself if everything else is working properly.
You can replace the screen independent of the phone but getting a genuine, just-as-good-as-original screen is...hit and miss. AT BEST.
Send it for an official repair.

Its verry easy to open an HOX. Maybe something loos
