Ghost touches? - Xperia Z2 Tablet Q&A, Help & Troubleshooting

I have the Verizon version of the Z2 tablet, the SGP 561, and I've noticed there are weird ghost touches that happens on it. Although, it belongs to my little brother, he's always the one it happens to. It's equipped with a screen protector and the genuine Sony tablet cover made for it. He'll play with something like Clash Of Clans and there's ghost touches that keep sliding the screen back and forth. This also happens on the home screen and it takes a screen shut off and on to make it go away.
It's rooted, bootloader locked, and has the latest update that includes PS4 Remote play. The problem already happened before the update. Can I get some help with this? Thanks in advance.

Hopefully I can explain this...

when I'm reading web page, and I'm scrolling up or down, the tablet randomly ZOOMS right in to part of the page i'm on. Often to a section that I'm not even reading. Is this a known issue? Am I doing something wrong?
thanks, hopefully someone knows what I'm talking about cuz it's driving me crazy!!
This happens to me sometime, all I can say is that the touch screen is too sensitive, I have to make sure that my finger doesn't stay on the screen to long.
Yeah the screen seems to have a sensitivity issue.
I'm just sayin!

Can't say it'a an issue, this happens to ipad and Samsung Galaxy tablet as well when I tried my friends' devices.When you get used to your device, this will happen less.

Hopefully this is the case. Then I'll less likely feel this is a problem isolated to my unit.

The Sony S is super sensitive to quiver-fast double taps and finger jiggles (that you may not know you are doing.) Pretty sure that you'll get used to it and, even without thinking about it, simply adjust your browsing method. Takes a day or so to get beyond it.
Well, I've got my tablet for a few months now and I think every day that this is a pain in the ass. Regarding this issue I love the ipad. Or my galaxy s. Neither of them have this issue.

Did you put a screen protector on the screen without removing the factory one? I did at first and was having the same issue as you. Couldn't even type a message because it kept double tapping letters i was trying to type and scrolling while browsing sucked.
I took off the one I put on and just have the factory one now and, though it still happens some times, it is definitely better than it was before.

Yeah I had to do this same thing. The extra screen protector desensitized the hell out of tablet S. I've taken it off and it's much better, but still double taps at times on 1 tap.

The salesman at the sony store put it on for me. So im not sure. I'd like to this he dd it properly.
I truly believe my tablet is defective. The problem I mentioned above plus horrible and slow scrolling, widgets disappearing, widgets freezing. Etc....
My tablet has been a lot better since I removed the protective film covering the screen. The cover was kinda thick. Now the colors are brighter and the viewing angle is better. I like the texture of the glass too.
I also don't notice the "ghost touches" that would happen right after I'd touch the screen, kind of like a double tap. Those were few and far between, but I've been enjoying my tablet sans protector enough, that this is just a bonus.
I'm not guaranteeing it, but this might fix your issue. You could also try replacing it with a thinner protector. My nook color's touchscreen was crazy without a protector, maybe this tablet is the opposite.

It also sounds like you could use a factory reset. I was having issues with my tablet being crappy and slow, and after doing a factory reset, freezing the unneeded apps (pretty much all of the Sony ones), disabling the media scanner, and applying the V6 supercharger script OOM values, my tablet has been pretty snappy.
I've been using the new Go Launcher HD home app in place of the default launcher which I froze (aka disabled the package).
Wait, there is a screen protector coming with the tab? I purchased the sony screen protector and put it on. So I've got two protectors on it?

Same with me, my tablet came with a free protector and the shop put it on for me. I am not sure if there is one already there as some insisted here but I have no sensitivity issue even if there are two screen protectors!
Yes it has a protector on it. It is very tough to keep the screen from getting cracked. To remove it, start at one of the corners with your fingernail. I used the bottom rounded corners to start. At first the screen will feel a little rough, but that's from the adhesive. Clean it with sone electronics spray and a microfiber cloth.
I like mine better with out it. The screen feels like glass now instead of plastic.
Yes..the tablet comes with a screen protector preinstalled which you can see if you look closely at the edge of the screen.

Here's a thread with pictures and info on how to remove the factory screen protector...

screen protector
I have the same touch sensitivity problems on my Tablet S (16GB WiFi) purchased in Singapore. Frequent hypersensitive touch behavior leading to random zooming and double taps, 'stickiness' in scrolling menus etc.
I read about the factory installed screen protector here on XDA but was unsuccessful in removing it...couldn't even get the edges to come off. Went down to the local Singapore Sony Service center and asked them to take a look at the hypersensitive touch issue...and what do you know...I couldn't reproduce it on the spot. Tried for 15 min, but the tablet behaved perfectly during the period . Couldn't convince the service tech that something was wrong.
Anyway, i asked them to remove the factory supplied screen protector and they said it should NOT be removed since it's not merely a protector, but a necessary part of the display for improving color reproduction and decreasing glare. Don't know if he was BSing me, but I left it at that. Note the image on this official website under the 'Sony’s amazing TruBlack™ display' section...
[EDIT: Looks like I cannot post a URL as a new user. Please check the Sony Singapore Tablet S official website]
I bought the official Sony screen protector (matte type) and had them install it. The sensitivity is much better now and the frequency of random zoom and double-tap has decreased drastically; but it's still there and pops up occasionally.
I am unsure of what to do next. Could it be a software issue? Among the browsers, I notice that it is most prominent/frequent in Opera Mobile. Occurs less frequently in the stock browser.
Today, I noticed that we have a possibility to set the sensibilty in our settings. Just go to input help (probably not the correct word... mine is german. It's the setting with the hand as a symbol). Within, there is a setting called something like touchscreen gestures. My tablet was default set to short. I changed it and now I don't experience the zoom issue anymore.

It's Touch n Hold Delay under Accessibility and default setting is Short.
I have no screen sensitivity problem on my tablet with extra screen protector on (I'm not sure if there is one factory installed on my tablet until today) so this function is useless to me
Hmm it seems that the touch and hold adjustment worked for me so far. Nice find!

[Q] Random dead spot on screen?

Hi all, sorry my first post is asking for help, but I'm lost on this one.
It doesn't happen all the time, but I randomly get a dead spot on the bottom right corner of my phone.
It happens when I touch the app drawer, and the L key when I'm texting. It only randomly acknowledges I touched the screen.
Restarting the phone usually helps, but does that mean it's software or hardware?
Should I have it replaced?
Stock VZW Note II, no apps installed.
Ty for any and all help.
-edit-
It was replaced for a bad digitizer.
When using Multitouch visibility test, if you put more then 4 fingers on the screen, it locked up the phone requiring removal of the battery.
Perhaps instead of software, could it be heat?
It sounds like a dead/dying pixel to me. If it is only there on certain screens, then probably not, but if its there on say the boot screen or something, then I'd take it back.
silhet ingliil
I'm sorry I should have been more specific.
It's not a screen blemish.
It's when I go to tough the screen.
Like if I hit the L key on the keyboard during a text message, it will only register a touch like 50% of the time.
Or if I touch the app drawer, I have to hit it multiple times to open it up.
The actual screen is perfect, no dead or stuck pixels at all.

I'd return to Verizon, especially if you're not rooted so it won't be any trouble returning to stock etc.
It's probably mildly annoying to you now and it's only going to get worse over time. If there's no physical damage to the phone I don't see them giving you any trouble.

No damage at all, and I actually went through 3 screen protectors before I figured out it wasn't them.
Kinda bummed I have to drive 45 miles to return this damn thing though.

You don't. Call VZ and they will ship you another and give you a prepaid box to ship the old one back in.

I actually called them, and they told me to just take it back to the store in case the replacement has issues.
Which is troubling to hear.
I have a youtube video demonstrating the problem, but I won't let me post it so ohwell.
Will have to wait til I get 10 posts.
Basically, using multitouch visibility test, I roll my finger around the bottom right corner while never lifting it off, and it won't recognise my trying to touch the specific spot.
After I life my finger and move it around the screen it will recognise the spot. It's very random.
Here's the video.
http://www.youtube.com/watch?v=SGl9RoBLpjA
-edit-
The youtube tags aren't working?
So what do you all think?
Hardware or software?
After further messing around in Multitouch Visibility test, I can replicate this all over the screen, but it's easiest to do at the bottom right corner where L shows up on the keyboard.

Nah, it was a bad digitizer they said.
Whenever you put multiple fingers on screen, it would lock up, and require yanking the battery to reboot.
When you notice this are you holding the S-pen? I noticed if you get the pen near the screen (close enough for air hover to work) that the screen and buttons quit working to touch. For a little while I thought the home button was having problems, turned out the way I was holding the pen would result in it being placed near the screen when I hit the button.

The main reason I noticed it was when I was texting.
Whenever I went to type words like sleep, or talk, they would be missing the letter L.
Or when I would go to open the app drawer, and it would only work half the time.
All while the pen was in the phone.
The lockup doesn't sound normal but as far as dead spots if you have a screen protector on have you tried removing it? Marginal screen protectors will cause touch input issues.

touch issues

Im so frustrated by the touch screen on my ZU, its so Sensitive (or under Sensitive ) that i always accidentally select items or make phone calls when i scroll through lists. I've updated to latest firmware already but same thing
Is no one else experiencing this? I only see a complaint occasionally. I brought the phone to Sony of Taiwan and they said it seems normal and dont recommend i send it in for repair.

Things like this are always a double edged sword.
On 1 hand people will see this as an issue and dislike it, or others like myself will like it as it makes the screen effortless to interact with.
I can see your point though, especially if you are coming from a device with a screen not as sensitive.
I come from an iphone, and have played extensively with a S 3,none of which have these issues,and are just as effortless

I had this problem with the Sony Tablet Z and it drove me crazy.. a software update fixed the issue but I returned the tablet anyways. But I have seen no issues like that with my Ultra Z.
Yup, updated this morning hoping for a fix but seems the same. ..trying to do factory restore right now to see if that helps
.475 seemed to have fixed that issue on my phone.

A factory reset DID help ! The touch still has occasional issues but much better now ... Finally can use the phone properly
Sorry, it didn't help. problem still exists and Sony is telling me this is acting as suggested. I guess I'll have to wait for someone (hopefully) come up with a sensitivity adjustment.
Did you apply any screen protector as certain bad screen protector will affected the sensitive issue.
Other wise, did you a iPhone ex owner. No biased on this, but base on what I had seen so far, certain iPhone owner can't proper use Android phone due to the touch & scroll method is different. Android only need to slightly touch not like iPhone need much pressure on it.
I've removed the screen protector, same thing.
It can't be an iphone vs android thing, the problem doesn't exist on Samsung devices I've played with or my Nexus 7.
It feels more like the screen is not sensitive enough? It isn't registering that I am still scrolling and so it registers a finger "lift" and selects into an item. Same thing if I try to hold a key on the keyboard to access secondary letter (holding down on a key to select comma, for example) it'll repeat hitting that key. I have to exert a lot more pressure and be very sure my finger doesn't move to properly access the secondary key.

The repeat-hitting when tap-hold is very abnormal. Why your service center didn't recognize that as a problem when they examine it? I think you should request for replacement.
I also had the same problem... touchscreen is a little bit buggy.. but the latest patch did fix a little bit.. but its still there. still far from my ip5 , s3 s4 note 1 note 2... hope they will fix these soon.
I have exactly the same problem on mine, sometimes is really hateful but for sure when rooted we will be able to change that value.
I also have major issues with the screen.
The best way to illustrate the problem is by holding a finger on the screen on the lockscreen.
It just flickers a lot like I'm tapping repeatedly on the screen.
I've updated and factory reset without it fixing anything :/
I was wrong, I still have issues. The newer firmware just made it overall a little "better" but I am going to send it in for repairs...this is ridiculous.

should I wait for next update?
I'm having the same issue with the screen sensitivity. It also skips when using a pencil as a stylus, which is the main reason I bought this phone- to draw and take notes. I don't like amoleds, need pentaband and can't fit anything bigger than the z ultra into my pocket. It has become very annoying, and I'm wondering if I should hold out for the next update or send it in now...I have no backup phone.

I've sent it in yesterday.
The Sony associate said he can see the issue as being "screen more sensitive than usual" but can't promise anything. He said he will demonstrate it to his colleagues as the repair form lists the symptoms vaguely as "screen erraticly jumps" which doesn't describe the problem accurately.
I will know within 2 weeks and post the results here. I am not holding my breath, though, as I think Sony has pointed out that the specialty feature of the ZU using a pencil to control the screen is produced by turning up the sensitivity of the touch screen. Kind of like Samsung Galaxy S4's feature of allowing users to use the touchscreen with gloves on. At least Galaxy users can turn the damn feature off!
Interestingly enough, while in the repair line I met another user who has a ZU and I asked if he had the same issues. He said no, he didn't have that issue at all.
Sony Taiwan sent it back to the repair shop stating they updated it to .475 and there shouldn't be any problems. Problem is, I already had updated it to .475 when I brought it in for repairs. Problem still exists and I have them send it back. If this doesn't improve I can only blame myself....should have bought a samsung!
Apparently Sony Taiwan refuses to offer any fix for this as they stated this "sensitivity" is needed for the pencil stylus feature.
Very unfortunate, very lame.
Anyone want to buy a 2 week old Sony ZU in Taiwan?

Replaced cracked Digitizer

I dropped my GT-P7510 and the screen shattered but didn't call out. I was able to use the tablet but was worried about cutting my fingers as I swipped. I bought replacement digitizer on Amazon for $15 and with the help of a YouTube video was able to remove the old screen and install the new one. It took me no more than 20 minutes, all I needed was a hair dryer and a few butter knives.
"This seemed too easy" was my thoughts as I was powering the tablet. Everything started up fine, was working perfectly UNTIL I noticed a few "dead spots" on the new touchscreen. One of which is right over the install button in the Play Store.
It's not the end of the world as this tablet is quite old and I really only use this to play Appeak Poker and the only new apps I install are the sponsored apps in Appeak that give me free chis just for running them.
Has anyone else experienced this problem after replacing their digitizer and if so, is there a fix?
Thanks

Try checking the connection between the digitizer ribbon cable and mainboard socket thingy. Push it as far as possible without damaging and press the clip to secure connector.
hi all,
first forgive me, english is not my first language
instead of creating a new thread, i used the search option and found that thread so ill post my problem here.
I own a p7500, and last week i dropped it on the floor and broke the glass. Since i use my tab for work i couldnt wait for ordering a replacement glass and do it myself so i brought the tab to a store close to my place named youbreakifix and they changed the glass for 100$. The lcd is 100% fonctionnal as well as all buttons.
now at first the lower right corner wasnt responsive at all as well as the bottom section of the tab. Also, sometime the whole screen wouldnt be responsive until i screen off then screen on again.
The guy told me he would open it and check all connections and if the problem isnt fix, he would order a new glass and replace it again.
Now the next day, they called me saying everything looked fine, i went to the shop and tried to swipe home screens from one to another with success.
Once at home, i started to play a little more with the tab and found that the digitilizer is still totally unresponsive in a intermittently way until i screen off and back on.
Also, when i press on some area (really small and alway at the same place) the tab look like it has a dead spot.
According to you, is it the glass that i should get replace again (on warranty 90days) or it might be another internal problem of the tab ?

Ghost touches

So I'm watching youtube on the dual screen using landscape and I want to sleep the main screen so i touch sleep main screen option on the dual screen tab tool, it shows a prompt saying main screen will dim to save battery and swipe to dismiss. I dont touch or swipe anything and the prompt swipes itself away and screen undims or sometimes doesn't even dim. This is also the case with Call of duty mobile, when I'm playing the game in battle royal mode the mini map enlarges randomly even if I don't touch it, and the voice chat options will engage and open without me touching those as well. Anyone else has this problem? Any solutions?
I could have sworn I saw a post earlier about ghost touches, though I can't seem to find the thread it was in at the moment.
I've been using the phone heavily since I got it on April 1st, and I have not experienced this issue at all.
Any chance you had an LG phone prior to this and used LG Switch to transfer over all of your stuff?
I've read reports here that doing so can cause some pretty serious battery drain and/or lag issues, so there could be other bugs as another side-effect.
Have you tried a factory reset?

I set aside the the dual-screen accessory because it's just too uncomfortable to hold for most use-cases.
I'll go dig it up, plug it in, and give it a shot later, when I have some free time, and report back.

If you play a YT video on the second screen and lock/sleep your phone, the second screen goes to sleep as well.
I didn't bother with headphones for this test, and noticed that the audio comes out of the phone's speakers.
It appears that the second screen doesn't have speakers of its own.
So yeah, you cannot watch something on the second screen while having the phone asleep.
And it make sense. It's just a screen. No second pair of speakers. No second headphone jack. No separate battery. No second set of modems, etc.

Actually you CAN watch youtube on the second screen and sleep/dim the main screen by using the floating dual screen button. It has an option asking if you want to sleep dim the main screen to conserve battery life. It does work for me now, I'm not sure why it was going wonky on me when I first posted but hopefully that it doesn't do it anymore. I'm guessing the tmobile April security update did the trick. It's just I have phantom touches on call of duty still.

This is also the case with Call of duty mobile, when I'm playing the game in battle royal mode the mini map enlarges randomly even if I don't touch it, and the voice chat options will engage and open without me touching those as well. Anyone else has this problem? Any solutions?

This is happening to me as well when I'm playing PubG Mobile. The ghost touches are happening not on the map but to the left of that. On another LG V60, the device would get random dead zones as well.
I'm going to do the following test and suggest you do the same and report back your results.
1. wait until the ghost touches start happening and flip the phone around. hopefully the ghost touch continues to happen in the same exact location of the physical screen, and it triggers a different button
2. remove the screen protector and try the tests again
are you using a screen protector?
might process a warranty replacement if the results are reproduceable

Oh, that is good to know. I'm not using the dual-screen attachment anymore (typing in portrait mode is IMPOSSIBLE with it), but I only ever used the Dual-Screen notification shade tile to enable the second screen, not the pill button thing. I should have explored our options more thoroughly. Thank you for correcting me.
Edit - I have recently added a tempered glass screen protector to my phone, and while it completely screwed with my fingerprint biometrics (I had to delete the fingerprints and redo them), the protector itself is not causing any ghost touches for me. And once I redid the fingerprints, there have been no further issues there either.

Yes I am using a screen protector and I was actually thinking that might be the problem, although it seems like a solid install. I just got the update for cod season 6 and I'm downloading now. I'll see if that solves the problem. I'll also try what you suggested and then post results
Update: so the cod update did not fix the issue, but I tried doing as you suggested and flipped the phone around and the problem went away. I then tried flipping it back to original and problem persisted. I think it is the tempered glass. I don't want to remove it since it cost me 40 bucks. Any suggestions?

So I installed the update for cod and it still had the ghost touch problem with the top right side of the screen, iflipped the phone per what jd254 suggested and I didn't get the phantom touches. I'm assuming it is the tempered glass that is causing it. I dont want to remove it cause it cost me 40 bucks.
2nd update: so I tried taking it out of the dual screen case and notice it doesn't have phantom touch ( I played a full game of battle royale) so I'm not sure if its the tempered glass or the case. Need to investigate more

Is the case touching the tempered glass anywhere around the the edges? If the case is pressing on the screen protector and lifting or peessing it even the smallest amount that could cause phantom touches maybe..just an idea
FWIW, I'm using both a tempered glass screen protector and a case that wraps around to grip the front of the phone a bit, and I'm not getting any phantom touches at all.
The case is NOT rubbing up against the edges of the screen protector, however. Which is fine, because if it were, it could potentially dislodge it.
Or, I suppose, cause phantom touches.

Ok more investigating and playing codm I notice that the mini map opens up when i perform a touch combination with my thumbs. So the map gets triggered when I press and hold up on the left side virtual joystick to sprint and press the jump virtual button on the right simultaneously. I can't recreate what button presses open the voice chat box, but now I have to strike the dual case as being the problem along with the tempered glass, at least i assume those aren't causing the ghost touches.
For anyone having touch issues, as a troubleshooting aid: enable developer options, and then toggle on "Show touches" and "Show touch data". Might help figure out what is going on.

I'm getting VERY interesting results.
1. dead spots: I moved my finger up the right side of the screen to look up. my character did not look up, which I would assume there was a dead spot before. This is incorrect. I can see the screen registered using that option mentioned above. the screen registered the action, but didn't pass it to the software?
2. FPS drops: I assume it's an FPS drop because everything was laggy when this happened. (PubG mobile was set to max settings, and runs 100% fine, until now) I was flying the helicopter, so I had several fingers on the screen at the same time, with a lot of rotational movements. the screen doesn't clear all of these movement data until I literally take all my fingers off the screen for half a sec. When I did that, it stop lagging.
3. ghost touches: Each touch on the screen has an x and y axis point to tell the software where it's being touched. With several finger on the screen (sometimes 2, but commonly with three or more), I noticed that the y axis for my left thumb and the x axis for my right thumb was creating those ghost touches! The screen would combine the x and y axis from different fingers to create a touchpoint on the screen.
so I don't care too much about 1 and 2, but... what can I do about 3?

Yeah I noticed a combination of touches triggers the ghost touch on call of duty, I could also be having the combinations trigger ghost touches in other game but I need to test more
