Touch screen problem

Gnopps1 — Mon, 31 Mar 2014 11:47:23 GMT

I'm having touch screen problems. For me the tablet randomly doesn't recognize touches during the below instances. In all cases either going to the home screen and relaunching the app or turning the screen off/on will solve the problem. The problems occur several times per day but not constantly.

Sometimes opening apps will cause everything but the bottom android-buttons to be non-responsive. This can happen in any app it seems, including native ones such as Google Play.
Sometimes the lockscreen doesn't recognize touches at all.
While charging I've had issues getting the touchscreen to recognize, disconnecting the charger has helped.
Double-tap to wake seems to be very moody, sometimes working sometimes not. Sometimes it turns the screen on even by me just holding the tablet with my palm resting against the screen.

While not a bug per se, but the android-buttons seem very picky that you have to hit them right on the spot to work.

I am having the same problem. At first I thought I had a faulty unit but after searching online I found out many people are experiencing the same annoyances. I got the LTE version. It would be good to know whether people at Sony are aware of this problem and working on it?

In my opinion this is the exact same problem that occurs on the Z1, the Z1s and the Z1 Compact phones. Sony knows about that touchscreen issues and reported the issue will be solved with the 4.4.2 KitKat updates. The update did not solve the Problem in any way which leads me to the assumption that Sony is unable to fix this obvious error because it is hardware related.

If you want to take a look at the discussion and how the error looks like on the phones here are the links to the threads of the xperia Z1 phones

Add me to the list, same problem. I do hope this is not a hardware problem and can be fixed by a firmware upgrade.

I have exactly the same issues with my Z2 tablet. But Sony Support has never herd of that. Are they deaf? The whole internet cries about this heavy bug. This was my first Sony device and probably my last. Sorry. The device is very good, nearly perfect. But a touchscreen is elementary for a tablet and it should work without any flaws. If there's no hope on the horizon, I will give it back. I want to hear a clear statement from Sony.

same problem. No answer to my email at sony-support since one week, except an acknowledgment of receipt.

In my opinion most users have the touch problem, but in most cases they can manage it by touching again.

But in some other cases, eg. playing games, it is a bigger problem, when you drive against a wall for example.

To me this is an industry wide problem. Had it on the Nexus 7 2013, the Galaxy S3, Galaxy Tab 2, etc. The worst was the Nexus 7, however!

It appears to happen to me on my new Z2 tablet when I use it on a table or other surface and I only touch with a finger without holding it with the other hand. Grounding issue?

I am also experiencing this one. It seems to be at its worst when the tablet is laid on a flat surface and can become completely unresponsive. I spoke to sony via the online chat and they couldn't help me. Has anyone got any closer to finding out if this is a software fix?

It seems that it is much less sensitive than on Z1 phone and other touch screens. I have a stylus for touch screens and it works great (I can paint on the screen) on Xperia Z1. Painting on Z2 tablet is nearly impossible. It looses focus.

But on the other hand I played a 30 minutes session in Beach Buggy Blitz yesterday while streaming audio to bluetooth headphones and haven't noticed any major problems.

For me the most annoing thing is total lack of touch response about 3 - 5 mm from the bottom of the screen. It means that you have to touch upper and center part of navigation buttons. It doesn't work if you try to touch them near screen/bezel border.

I've noticed this as well, primarily when using Chrome, the back and Home screen buttons can sometimes not respond at all and it needs a few presses to finally start working.

Gaming however, seems unaffected and these problems do not occur. Believe this is just a software issue and an update will fix it, however as customers we do expect Sony to respond to our concerns so we know it is being worked on.

Not cool, Sony.

And guys it would be great if we can follow like XDA or post at XDA http://forum.xda-developers.com/showthread.php?t=2735460

It gives more than just saying experiencing touch screen issue and i know sony keeps an eye over at XDA. I really hope they fix the issue asap as I know some of us is getting near to the refund date or may have passed it.

And guys keep in mind that just cause they are not replying doesn't mean they are not looking into the problem, the customer service wouldn't be able to give you an answer if the technicians can't even pinpoint the problem yet. Anyway good luck to them and wish for an official statement from them shortly

ps: sorry about the double post, cannot seem to make edits through the phone.

I have the problem... doesn't happen all the time, but I notice it approximately once per day. Either the lockscreen won't respond or some part(s) of the screen become unresponsive. My previous tablet was Samsung Galaxy Tab and it didn't have issues like this, and neither does my Xperia phone which has been working flawlessly. It's a shame, the Xperia tablet received many tablet of the year awards so I assumed they'd be high quality. Well, otherwise I've been happy with the tablet, but the touchscreen issue is quite annoying so I hope it gets fixed eventually.

Copypaste from the XDA forum...

i sadly have the same problem the touchscreen is very slow to press either the menu button or home button you have to press it very close to the center of the button which causes ALOT of faulty presses and annoyance
