Hi there and welcome to the Community

Was it like that from first start up etc? Or has this happened after you updated it?

I'm having the same problem. For me the tablet randomly doesn't recognize touches during the below instances. In all cases either going to 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.

Hello
Yes it like that since beginning. I was reading one of the review where i found that the update to the newest version via PC Companion help a bit, but still is not responsive as my other touch devices. I have the same difficulties as the Gnopps. I would expect more for that price

I have the same issue since the beginning. Sometimes the touchscreen does not respond. I have to use my touchpen with hard pressure to get a reaction. Also my fingernail does not work properly with the touch panel. The sensitivity is rather bad. Same for dry fingers. Sony does not know anything about a touchscreen problem.

Hi all

I'm wondering whether this is a 'batch' type problem or an actual software problem etc?

Have any of you managed to try one that isn't the one you bought?

Have any of you exchanged / tried to exchange them?

I also have severe touchscreen problems. Forums and blogs are full of reports of this kind!

Again and again it happens that touches are not properly registered; that tapping on something causes nothing to happen; that even for longer periods the touchscreen is totally locking up! Then it's not even possible to unlock the lockscreen!

Seems to happen more when the tablet is connected to the charger; but not always, there is no really reproducible pattern.

SONY, IS THERE A FIX UNDERWAY? OR IS IT A HARDWARE ISSUE? PLEASE ANSWER!

Hi. I received my white 32Gb Wifi only Z2 yesterday and found I have exactly the same issues that have occurred from the beginning. I find that sometimes when waking the unit the swipe to unlock doesnt work, I also find going into the app drawer via the dotted square button / area at the top right is very problematic. Touch in general appears to be very poor. My concern is that Sony is fantastic when you have a working product, however in the past if I have had issues, I have found Sony leave me out on a limb (I was told once that the resonance from my Sony TVs speakers was because the TV was designed to be in the middle of the room and not against a wall or in a corner of a room!!!). I have come from an iPad V1 which has and still is faultless. I have a Z2 phone on pre-order and now I am getting worried that the tablet may be rogue. If it is a hardware issue then I want to be able to return the unit under the normal return period and not get into any of the usual Sony warranty issues I have experienced in the past. I really hope this is software and a patch emerges very quickly, somehow I doubt it.

Hi,

I got the same problem. I touch the display and get no response, I then touch it a bit more firmly and it respond. I find this very annoying and will have to return it if there is no fix for it!

16gb wifi version.

Hi. I noticed on the net that Sony released a firmware update for the Z2 phone yesterday (4 April) see this. I wonder if they have done the same for the tablet as it is essentially just a larger screen version of phone?

I discovered that when you switch off stamina mode touch screen get more responsive. I think touch response issue might be caused by power management in tablet, so that would be software caused.

I just wonder is it because small battery capacity Sony reduced power distributed to display to gain some more work time.

Thanks for posting majki_one.

Can others having problems check to see if turning off stamina mode helps?

(It's not a fix but it may make it more bearable)

HI All

IM having this problem as well i see it mostly , and quite seriously, when i have a micro USB cable in and the tablet is charging. Over on XDA it looks there is a report of .55 firmware release in Taiwan/China that is said to fix this issue.

Thanks flipside101 and welcome

Just out of interest have you tried truning off stamina mode as mentioned in a post above to see if it helps a little?
