Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

Sorry to hear that you're having issues with the touchscreen.

Does this happen when a certain accessory is connected to the phone or when you run a certain app in the phone? Does it help to wipe off the screen and turn the display off and on again?

Could you please send me a PM with the following information and i'll forward it for further investigation:

When I'm in the input state, the screen occasionally uncontrolled.Through close and re open the power supply button can solve but that give me a big inconvenience. Based on the understanding of many users, the prevalence of this problem. Please pay attention to and give a reply.

Hi !

I received my Z2 in France less than two months ago, and it's been having ghost touches for almost two weeks now...

That phone is crazy, screen often spams itself (like I don't touche anything but it recognizes multiple touches at some locations on the screen), and some zones that I touch makes the phone react in another zone !

This is the first post I can find on the internet regarding the same issue. Has there been any development on this problem ? Is it a hardware issue ? What should I do ?

Thanks

Having the same problem on my Z2, although it appears randomly. But has happened quite a few times.

Since I'm not the only one having this issue I'm going to share my experience here, even tho it seems like only a few z2 are going nuts ^^

after a month trying to find a solution on my own (I made my z2 sleep in a bowl of rice for a week for nothing just in case), I gave up and went to my phone carrier (SFR from france, fyi) to get them to handle the return to sony's customer service.

Yesterday, after a week that my precious has been gone, I went to get back my z2. Except all they did was a "software repair" ("90% of smartphone troubles come from the software" they said to me when I didn't seem convinced...). Well, I turned it on while getting out of the shop, praying to the seven gods and the old ones that it would work perfectly (as it should) and a couple minutes later it started doing the same crap all over again...

So to put it in a nutshell :

it's not a software issue (the fact that this phenomenon appeared only occasionnaly on different devices (xperia z2, z1, ipad 2 (just what I found while looking for ghost touches issues) sustains that theory),

and I have to go back and yell at anyone until I actually get a working phone...

So I'll keep you updated, in the mean time good luck trying to type a text message

Hi,

Actually this was the reason i joined this forum, to find out why my Xperia goes nuts sometimes.

I had it for about a month and then it suddenly went from fully functional to totally dead, without me dropping it anything else.

So it got repared, and after i got it back it has flipped out twice like 22 fingers touching the screen at once it opens and closes everything, takes screenshots etc.

However, i do know that this problem has only occured when i have had the application Player Pro open.

If it's a problem with the application or the phone, i don't know...i use the app all the time.

Hi, exactly same problem here. Screen goes crazy and taps all over, most of time I have to power off the phone and turn it on again for temp fix, is there a possible solution?

screen touches itself

Demo — Tue, 15 Jul 2014 20:46:46 GMT

Phone not even month old, screen sometimes goes crazy and it's like all screen is getting touched by numerous invisible fingers same time, sometimes I have to switch phone of and sometimes just not using phone for some time helps. It writes in viber, ir starts sending invitations and posting in Facebook, moves apps in home screen and does more random stuff, also disconnects phone calls, is there a fix for it or shall I take it back and never go for Sony again? (this is my first ever Sony product that I did like untill all these glitches appeared)

how many times have you played the following video: https://www.youtube.com/watch?v=wv-34w8kGPM

That could be the source of your problems?

Re: screen touches itself

Zann_H — Tue, 15 Jul 2014 21:15:18 GMT

1: Are the phone being charged when this happened?

2: What version is your currrent firmware?

3: Does this happened after you install any apps?

3a: Can you list the additional apps you installed on your phone?

3b: Is it possible for you you to do a factory reset and see if this happens with no additional apps installed?(please backup your data first)

I'm asking all these because I'm trying to narrow down and find a common ground for this strange behaviour.

Re: GHOST touch problem...Z2

Demo — Wed, 16 Jul 2014 07:29:28 GMT

Phone not being charged, all original, newest updates, not big fan of many apps, so no, no installations after 2 days of getting phone, don't want to proceed with factory reset as cause is unknown and don't fancy doing it every month

Re: GHOST touch problem...Z2

Zann_H — Fri, 18 Jul 2014 06:08:42 GMT

SInce the phone is fairly new, I would suggest that you do a factory reset. Or better yet, do a repair. If it's not caused by corruption in the ROM itself, then it's mostly probably a technical issue. That's why I suggest you do a repair first with PCC. If the problem still persists, send it back for service or exchange if it's still possible.

Edit: Ignore the 'factory reset" because I doubt that will solve it. DO a repair if you can.

Im going to try the repair thing to se if it solves the issue

The issue is a hardware defect. Even the slightest bit of moisture or debris on the phone's screen registers as a touch. The only solution to this problem is to keep your screen 100‰ free from moisture and debris, as it is simply a design flaw in the phone.

Yeah that seems like the most logical explanation. But for a device like that, such a flaw is unacceptable ! So the only solution is really to keep harassing the customer service until they change your phone.

To keep you updated as I said I would, I sent back my phone through my phone carrier for a second time. This time the guy wrote exactly the symptoms as I told him, and I showed him on the phone using the "multi-touch tester" app (very nice to seem how crazy your screen is ! I managed to get 5 touches at once with only one finger...). On top of that, the usb port's lid was damaged, it kept opening in my pocket and even got detached from the phone (so much for waterproofing...).

When the phone came back from repair, it was still as crappy as before (all they did was the same useless software repair as the first time, and nobody even touched the lid). I immediately showed to the guy from my phone carrier's customer service that sony basically did nothing, and then he gave me a brand new z2 from a closed box in replacement.

So right now I have a new phone with no flaw, everything's shiny, but I'm still afraid to get that kind of trouble again.

But anyway you have to keep complaining if you want to get a properly working phone. Hope it can help some of you !

PS : if anyone from sony here reads this, I'm really disappointed for the inefficiency of your customer service. And please stop sending me any kind of satisfaction inquiry, I guess this post is enough.

If it's just moisture or debris has anyone tried putting a screen protector on it? Probably won't work but it would be nice if there were such a simple fix. I am on my second Xperia play. I smashed the first one after it dogs this for a month and irritated me to no end. The one I'm on now last night abruptly decided that it was January fifth 1980 and that I had missed 52 calls. I am also wondering if there is a way to turn down the touch sensitivity...
