This problem may be caused by bad insulating.
But I don't know this problem is occurred in all Z1s.
This problem of touch panel can be occurred variable timings.
People who playing games or using pattern lock will recognize this problem easily. but difficult for who Not playing games or Not using pattern lock.
This method can detect the potential error of your Z1 it looks no problem.
Please test your Z1. and if the problem is reproduced, you should go to store and make a claim!
and replaced one if you get, please re-test and report here.

My Z1 also have this problem. After 40seconds i even didn't have to touch this two sides of phone.

For few weeks I never saw that problem on mine so I was not worry about it but today I tested few nice games and I realized that after a minute playing the game (Minimotor or HAWX) the virtual joystick stopping working. I have to retouch the joystick with my hand or take off my hand from the phone. All the time.
My question: this is a Hardware problem?

This ploblem can solve by updating the driver software. like Xperia tabletZ.
Hang in there!

In the next week i will buy this phone when i have enough money.

How it's possible the problem of the touch screen is because is too sensitive? I hope there is a solution via software but for there is some lack of insulated between the touch screen and the rest of the phone. That why when you touch the frame the touch respond very badly.

I think the screen react to very few electrostatic.like touching side panel.
so to make less sharp ,It will be ok. perhaps.

Confirm the problem in my device, hopefully a fix can be found, mine ain't so bad I guess cos it happens only when I press the sides

Actually, It is reported that replaced one has this issue too in Japan.
Sony don't recognize this issue yet!

I did a video by myself and I don't get it! Where is the problem? I mean where is the problem causing the touch screen failing to work. The only 1 thing what I am sure is if I leave the phone for 20, 30 seconds the issue show up with my touch screen with or without touch the aluminum frame.

Exactly, I think we are close. The problem appear after long or prolonged use with the touch screen.

No issues here, i tested for like 20 minutes and its perfect here

i bought a Xperia Tipo for my baby brother last week and it has touch sensitive issues just like SP when it placed horizontal ( i watched the Utube Videos and it looks exact the Same) but i found a little Mod App called (Touch Calibrate) i want you test it for me and say that if that worked for you or not!

Touch Irresponsive, Screen Freezes
Like a lot of users, I am also having problems with the xperia SP's touch screen. The touchscreen becomes randomly irresponsive. Sony acknowledges the problem and suggests:
"This have now been investigated and if you experience this problem I advice you to contact your local support team to have your phone calibrated at a repair center."
The problem is in live in Bangladesh and they do not have official Sony tech support centres. Does anyone know how to do the touch screen calibrations ? Any DIY solutions will be highly appreciated.

Z1 Touchscreen Issues

Does anyone have issues with the touchscreen skipping every once in a while? Occasionally, there is an area on the lower half of the screen that seems to be insensitive, but if you start touching around it, it goes back to normal.
I've discussed this with some fellow Z1 owners and it appears to be a relatively common issue. There is some discussion that it may be due to overheating or a software issue.
Anyone else have this problem?
Had this once while my device overheated hard(~47-48°).
Not sure if I have to be concerned about that, because otherwise it works fine.

Same here
Sent from my C6903 using XDA Premium 4 mobile app
At first I thought it was an issue with crappy screen protectors. The Z1 already has a anti-crack film on the screen so I thought that adding a poorly made screen protector would create too much distance from my touch to the sensor. However, I've tried replacing the screen protector and also asked other people with varying brands of screen protectors and it seems that the issue still persists.
The issue seems to occur most often on the password screen for me (which is particularly annoying).
I've had it too, lower half of screen does not register slides on login screen for a brief moment.. No overheat!
Sent from my C6903 using Tapatalk
No overheat here 2 but with the same issue.
Also the last days i think that all the screen sometimes is more insensitive than usual.I have to touch 2-3 times to do what i want.
I think that is a hardware issue.
Have it sometimes as well sadly! Can't figure out when exactly it's happening though..
I find it very annoying when I'm scrolling and at the bottom part of the screen, the scrolling becomes a click, which brings me to a place I did not intend to go to. Hope it's software, but can't imagine that.
Happens to me as well, regardless of device temperature. Based on the seemingly random nature of the issue, it should be a simple fix via software update. A similar bug persisted on the 2013 Nexus 7 devices when you laid them flat on a surface.

Same problem here!!!
I think is a hardware issue. When you touch the alu frame the phone works fine. If the phone is on the table or in a cover the issue are immediately there.
Sorry for my bad english. Hope you understand
I noticed some small things and thought it was me but I guess this makes sense.
Could be worse, my previous Note 3 had multitouch issues and had problems register several fingers :silly:
Considering how common the issue appears to be, I find it hard to believe that this is a hardware issue.
I also don't believe it's related to overheating since it seems to happen even when I haven't used the phone at all for a long time.
It feels like a software issue to me since the issue sends to go away if you touch another section of your screen

I am having the exact same issue. The weird thing is, is that it doesn't always fail to register my finger. I've gone a few days without it, then suddenly it's back again. Also in the Xperia Diagnostics app I could then see the phone failing to register a proper line, then 20 seconds later it's gone. Weird thing indeed.

Yes, I have it as well.. First of all though, to reply to a lot of people on this thread, it happens regardless of "flat surface, touching the frame, overheating", or anything else. It seems to be completely random with me. Sometimes everything is perfect, then it goes nuts for no apparent reason whatsoever. I'm almost sure it's a software issue, and hope sony will address this issue soon!
it also happens sometimes to me.
the only thing that helps is to touch the ground of the ac power socket. it seems like the screen needs much more potential difference between the pointer and the screen itself and after a while of using it the pointer (you and your fingers) are more loaded.
thats my theory to it.

Unfortunately, unlike the rooting camera bug, it doesn't sound like Sony has even acknowledge it at all.
Exactly this.

I often have to attempt inputting my password multiple times before I can finally get it right. I have since switched to PIN unlock. Really wish there was some sort of response from Sony.
I'd you're using pie then stop using it and retry the affected area. I had this issues because of the activation area causing certain keys on the keyboard to become non responsive.

I haven't as yet but I did notice that the touch screen issue I had where my finger / thumb would lose contact briefly with the screen.
Hasn't happened a lot and holding the metal frame fixes it.
What youre describing could be a knock on effect of the new firmware having a higher sensitivity to the previous firmwares, I know Sony were aware of the touchscreen issue that people were facing and there was a fix where you could alter the sensitivity of the touch screen.
Could be that your touchscreen is set too high for your device in particular, either that or it's a problem with the touchscreen or even some dirt.
Give it a good old clean and a few reboots.
All the above is speculation of course, just having a stab at it for you m8.
Not sure where that thread is about the touchscreen but it's definitely in the Z1 forum.

Actually Rooting can cause the issue because the Pre-Rooted version can be different from the original one installed on our phone.
After I received the phone from Repair they updated the Software and then I updated to .136 officially and the issue disappear, never had even a bit of it. Then I rooted, but to do so I used a different Base, NUT use the Frence region I think, and after that on mine .136 the problem with Touch Screen appear again, not badly, all is fine but sometime it skips something.
So I think it's really related to the Software and the all the phone have a specific Base.

Then it would be down to the rom and not the rooting process, rooting alone won't affect the touchscreen m8.

Of Course.
i have not experienced ghost touch but i did experience the screen failing to register two finger touch sometimes.
what i mean by that is when u quickly touch another part of the screen after its been touched it would register it as a swipe.
very annoying when typing keyboard or even pressing key pin on lockscreen.
i reproduced this in touch test and
once it registers as a faulty swipe while holding down the touch
it keeps registering swipe wherever the other finger presses untill i stop touching.
also when i installed a fresh rom it seems that the touch is very sensitive.
i tried this out http://forum.xda-developers.com/showthread.php?t=2691849
its not a fix but it helps out.
I think i have drilled down to the cause for this issue.
1. I started mounting my phone on my motorbike and ride. Due to excessive vibration the screen might have started acting out.
2. I also read that x alert causes this.
I have locked bootloder and installed stock ROM. Lets see whats happens

Been trying to find that adjustment you can make for the touchscreen but can't find it. Its an adjustment of a file within android which deals with how sensitive the touch screen is. Buggered if I can find it though. I commented on it too. Eluded me.

I am unable to pin point the problem.
1. Its not bcoz of root/boot loader
2. Not bcoz of mouting it on my bike. Infact when i mount it, it functions normally.
3. Ghost touch worsens when i play clash of clans but it is there other times too.
So its either bcoz of over heating (games make the phone heat a lot) or water entered it or i am not sure.

Touchscreen issues

I've experienced some serious touch issues in the past two days. It's happened very randomly and I can't replicate the issues. The screen losses touch sensitivity and I can't do anything, then it randomly comes back after 10 seconds only to animate every touch I made during the 10 second lull.
Has anyone had any touch issues like me?
Edit: disregard this post. got the forums mixed up with another device.

Have you updated to 5.1? Since 5.1, there were significant changes that appear to have been made to proximity sensor that seem to be affected by any sort of screen protector that may cover it. If your protector covers the sensor, then I suggest removing it.
I haven't. I currently have the notification on my lockscreen (since I can still use the power button and view that basic info). It simply just stopped working while I was using it. Going into the Sprint store early this afternoon
My N6 arrived yesterday and was immediately unusable. The keyboard filled in a ton of garbage when I was asked to first enter my name ... Power cycled to try again and have had nothing but reliability issues with typing at times the screen will lock while trying to type (no response) or assume I've clicked when I haven't which makes accurate data entry impossible.
wiped, reset and upgraded software from 5.0 to 5.01 to 5.1 - had to remove my ATT sim which initially blocked this process and reset. Issues are still present seems like the screen is defective.
Support has issued an RMA to return the device after suggesting they would replace. Not a great start.
im having the same issue with my nexus, i went back to stock, not even rooted anymore, still doing it, its driving me nuts..
RMA. It's quite obvious you have a hardware problem.

Although we're in an pls thread, I tend to agree. If it was a hardware issue, I don't think we'd see the OS acting out the touches later.. It means the hardware actually accepted the input but the OS didn't do any thing., Likely an OS hang or something.

Xperia XZ2 touchscreen issue?

After reading this forum regarding Xperia XZ2 touch issues, I decided to test my XZ2 touch screen. When I test it using service test (*#*#7378423#*#* >Service tests>Touch>Draw grid test), My touch screen never registers the bottom left and right edge grid. Does anyone have the same issue? Do I need to sent my phone for replacement? Here is the screenshot of the grid:

Better sent to replacement.
That are dead spots which aren't on the most devices.
No issue on your test ?

That looks fine. I also get spots where it stops responding until I tap another area of the screen, bottom corners and a patch about a third of the way up on the right side. Phone has been replaced by Sony but it has the same issue, they said it looks like a software issue. Not helpful.
There no issue at all according to his screenshots, the bottom left and right small spots are not supposed to change.

I get the same results so I know the digitiser is fine, it's these dead spots that annoys me. Two phones now have this.

Repair phone with pc companion should fix it.

I've tried that on both handsets. It does only present for me with certain apps, other apps are fine, so I'm unsure exactly what the cause is. I don't understand enough to be able to fault test it but it seems like a driver issue. I have a game that does it constantly, but it's fine on other phones, the Facebook app does it also, chrome is another, twitter is fine, banking app is fine, Sony home does it but lawnchair doesn't, it's annoying lol tbh I'm so used to it that if a tap doesn't register I automatically tap another area and then try again.
