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.

Does anybody else have a problem with their Play's touch screen?
It is when my hands are warm or clammy or in a hot environment, or if my hands are sweating a little.. then when typing the touch screen just goes crazy. By crazy, I mean it keeps making random taps everywhere, and with Swype keyboard, gets really annoying!!!
Any tips? I have tried cooling down my hands under cold tap, using paper towels to dry them, drying the screen. I think maybe it is because the phone gets warm because overclocking to 1.5GHz...
Yeah, I had the same "problem". The touchscreen is thermal-based so it will act accordingly to any thermal temperature imput. For example, try blowing hot air to your screen for a short period of time; you'll notice it will go as crazy as you described it. To me, it happened when I was speaking to someone for a long time, my ear heated the screen and after the call ended, the phone was acting on his own.
Cleaning the screen will solve this funny problem.
Not too hot in the UK so not really faced this problem. What is annoying is when I'm in the middle of swyping and the phone just stops my Swype and doesn't work temporarily when I Swype over certain letters

Well, my touch screen basically quit on me... sometimes there is massive touch screen lag, and after awhile it just quits...

Hmm, I am in the UK.. it isn't that hot, I am even in an air-conditioned office but as soon as my hands get a bit clammy (always!) then it just goes crazy on me. I thought it might be the screen protector, so I took it off, but still having problems. It is getting to the point where I am considering a new phone.
Try punching it

Yes punching is a resourceful method of permanently ending all of these problems. But if you're looking for something a bit more temporary in it's resolution, use some rubbing alcohol, and clean the screen with it. Also your flex cable could be on the way out... when it starts wearing out it does this. Open the gamepad the next time it starts going mad and you will see it stops
I'm not having any probs. Normally when its hot, my stock ROM get into 42celsius .. With overclocking it would be 50+..

I'm in the UK and I have this problem every day, I've had to start using a stylus to type, it's so slow, I posted about it in the Q&A section and someone said to get a screen protector.
I have the same issues, too.. it sucks, it's making it very hard to swype.
I have noticed if I swype in landscape the problem doesn't exist, only in portrait.
And, I've flashed a new rom and it still happens, so not a software issue.

Hard to replace cable? I was thinking about ordering a new touch screen digitizer but when watching the tear down didn't wanna take apart the entire phone.
Yes this does happen. This also happens when the charger is plugged in.

I had a screen protector and still had the issue, in fact it seemed worse with that, so I ripped it off out of frustration.
I will try some rubbing alcohol (may get some alcohol wipes or something) as I know that dries things out, and it seems to be moisture and heat that makes it bad.
I guess my next question is, why does it only happen in portrait mode? (if it is the ribbon cable thing, that sucks).
And also, is this an issue for other phones? I am guessing not
I've found that if my screen starts going "click crazy". I just turn off the screen and turn it back on and it solves it.
Why it happens? You got me.

It happens to me in Landscape too
....so no-one has a fix for it?
No idea.. sucks because looks like a bunch of us have this issue, too.
Same prob here!
It starts a few months after I buy the phone, and I take it to the warranty.
They changed not only the screen, but the whole front part, and it seem that was ok. But some months ago I noticed that it was back.
I already try using stock GB, other GB roms, ICS roms, and the problem continues.
But for me it happens only in landscape mode. In portrait mode I rarely have problems.
had this problem before I bought a decent quality screen protector.

what do you mean by punching?
I am desperate in trying to fix my Play. I want to try everything first before I buy a digitizer.
Also happens to me, when it does i lock the screen, wipe it with my shirt and i turn it back on and it's fine.
I bought my Nexus 7 2013 32gb model from Amazon and got delivered early before official local availability. I have noticed some touch problems in various apps (Pocket, Youtube, Chrome). I turned on developer settings and then turned on "show touches". When have problems it's like the touches are never registered. It's weird because its not consistent. I am considering sending it back for a replacement, but I have a friend who picked one up locally and has similar issues. I am wondering if this is a bug in 4.3 or something like that.
Any thoughts? Anyone else have this problem? RMA or keep it?
Flashing a different kernel could fix your problem as that is what bridges hardware and software.

Looking to remain stock at the moment. I figure if its a kernel/software problem google will release a fix fairly soon. If it's a hardware problem unique to a small number of devices like mine then I would like to RMA it.

Yesterday mine was fine and today when I was typing in landscape I was having the biggest problem getting the letter b to go through I actually would have to hold it for a brief second.... Then I restarted... And now bbbbbbbbbbbbbbbbbb.... Yup everyone goes through I have a feeling its a software bug but I'm staying unroofed till I know for sure ...

dolphin does the same sometimes. i like NEXT browser
the screen seems to be too insensitive imo.
i tried on my old nexus 7 and nexus 4 to keep swyping between "n" and "d" in the stock keyboard, they register all the gestures without dropping in between. However in the new nexus 7, it often drops my gesturing if i don't press on the screen hard enough.
Kind of makes me wonder if it's the calice I have on my thumb from using lighter too much

I've noticed touch issues on my otherwise flawless screen (no dust, dead pixels, or multitouch issues other than this specific scenario) due to what I assume are grounding issues. I did some testing:
If I lay the tab flat on a table, and touch it with 1 finger, touches are only registered maybe half the time.
If I touch it with 2 fingers, no issues at all.
If I'm holding the tablet in one hand and touching it with 1 finger, no issues.
If I merely touch the case (not even the screen) with one finger while the tablet is flat on a table, and touch the screen with 1 finger, no issues.
Anyone else notice this?
My keyboard inputs letters that I don't physically touch at times when I'm writing a sentence so there definitely appears to be an issue with some units at least. I've never had this same problem on any other touchscreen device.

Exchanging mine tomorrow.
Kills me, I had a 16gb with no issues at all, then earlier this week, exchanged for a 32gb and this one has touch issues! I also noticed right away that this 32 was noticeably more laggy due to a few milliseconds delay when I tap in one of the "bad" areas, which tends to be the top half of my screen.
GT-N5110 wifi version. Ive had this device for 10 days. Out the box it was running 4.1.2 and seemed work great other than the occasional 3-5 seconds when screen would become unresponsive during normal use. After using it for a few days I decided to go ahead and update to 4.2.2 thinking maybe it would fix the screen issue. It did fix that issue but now im having another problem. After the device sits dormant for awhile the screen doesnt respond to touch but still works fine with the s pen. Ill turn it on after sitting all night and after swiping to unlock the screen it becomes unresponsive. I usually have to lock/unlock the screen several times before it will start responding. After it starts working I can be on it for hours with no more problems. But if I lock the screen an set it down for awhile when I go to use it again it does the samething. It seems like it has to warm up. I tried doing factory data reset but that didnt help. It is rooted also but the only thing ive done so far is get rid of some bloatware.(i didnt root it untill after the problem started). Anyone have any advice?
Do you have your note in a cover , and if so does it have a magnet.

That does sound rather crazy, the unresponsiveness is out of the ordinary... did you try turning off a lot of the extra features built in by Samsung? another thing you could do is download Clean Master from the play store and take a look at your Ram use-age and clean out some cache files with it, this might help with the lag. The touch response could be hindered due to a case or screen protector... other than that the only thing i could think is if there was physical damage done to it before that could cause the touch screen to act that way.
Ummmm... I would have taken it back to the store and asked for a replacement.
That is not normal at all. even with the device's settings left alone, there should not be any issues with responses with touch.
Note... The pen feature is totally separate from touch. The screen has two different features, one being a digitizer for the pen function the other for touch. It is possible that during assembly that the connection for the touch screen is faulty, as a bad solder joint during wave process could make the connection heat related. As the device cools, the contacts contract causing a fault with touch operation. When heated up from normal use, expansion forces contact between connector and board for normal operation to function with touchscreen.

Thanks for the FYI. I was using the moko whatever with a keyboard and I got the freezes all the time. I was thinking about the official Samsung one but if that gives you problems then forget it. I almost sold this thing on eBay cause I couldn't take the freezes anymore. Now I use a tpu case with it and couldn't be happier
