Hi! My first post here
Just got my P9000 yesterday, and while playing with it I noticed that the touch response is pretty laggy. I can see that when my finger is dragging down the text follows with a slight delay. I'm comparing it with my previous phone (Sony Z3 Compact) and it was much more responsive there.
A test that I'm doing is by using the app Multitouch Tester, and when moving the finger around the screen quite slowly I can clearly see the circle lagging always behind.
I also tried flashing a different ROM to see if it makes any difference (tried Eragon 4.0), but with the same results.
Does this happen also to you? Any idea what can be done to improve this?
Thanks!

Yup, there is definitely a lot more delay compared to my Nexus 5.
Thanks for confirming I'm not the only one...is there any solution to this?
Touch screen repair on play store did the fix for me. Try it if you want, I had I good outcome on my phone in stock rom

Hello all! I installed ICS on my GS2, rooted it, using the XALPQ firmware, and everything's pretty decent. However, I've had problems with sensitivity and I did a quick search and it appears that other people have noted that sensitivity has indeed decreased. Is there a tuning app that can recalibrate? Scrolling sensitivity especially is infuriating.
And speaking of scrolling, I don't know if anyone has noticed before but when (for Dolphin anyway) when a reformatted page was scrolled there used to be this kind of 'lock' that basically makes it resistant to scrolling horizontally if you're scrolling vertically with the text in formatted. That seems to have disappeared, for Dolphin and the stock browser. Anyone else noted this?
Finally, the heating issues the GS2 had seems to have disappeared but it appears there is a dramatic decrease in performance when doing intensive tasks. PDFs have become extremely laggy if they contain a large amount of pictures. Before the GS2 used to load them fairly quickly but got very hot; now it just does it extreeeeemely slowly. Is there a cap on power consumption or something with ICS, and is there a way to circumvent that?
It's my first post so I hope you guys won't destroy me utterly.
So I think I've figured out half the problem. Using Touchmove I can see that the actual sensitivity is okay, BUT there's something wrong when it first registers a response. The spot that your finger touches registers a response but small movements will not. However, once your finger has left that initial spot and gone a certain distance, it well start moving normally. If you keep your finger on the screen you can see that even if you move small distances now the phone will register your movements normally. It's just that single initial spot that's problematic. Anyone know the issue?
I thought it was only me upgrading P920 from GB to ICS and JB and got touch problems, but a quick google with "ics touch screen issues" reveals a lot. This problem seems well-spread across devices, ROMs, kernels,...
Basically the main problem is that it's harder to get the phone to register/recognize a touch/swipe. I sometimes have to touch/swipe multiple times for the action to happen. Sensitivity doesn't seem like a problem here, because a very light/soft touch can still be recognized. It's just that the screen often doesn't recognize the touch. Turning on pointer location in development options is the best proof. Try tapping the same spot on the screen lightly (as normal use) and some times it will register the touch, sometimes not. At first it seems like no problem but gradually becomes very itchy for everyday use. It's like using a defective product. But it is definitely NOT a hardware issue, because every time I revert back to good old GB (any version, any kernel) the touch screen just comes back alive. Every slightest touch and swipe registers beautifully, never misses.
So if your device does not suffer from this problem, lucky you. Us who are suffering from this, would like to have some cues on how to solve it.
NOTE: SGS touchscreen booster DOES NOT solve this issue. It's a great tool, though, to increase the touch sensitivity. But as this is not about sensitivity, it's useless for me.
So anyone have a solution? Thanks in advance!!!
Hi, i have had my tablet for about 1 week, straight after starting it up i had a fw update which is 17.1.1.A.0.402 which i am assuming is the latest?
anyway i have read a lot about the new fw was supposed to fix the touch issues?
I also have the z1 which i still have and is perfect. ive recently updated to 4.4.2 on that and all my issues are fine on there.
my z2 is acting very strange, if i leave it alone for a while sometimes i will go on it and everything on the screen will be frozen, i can't tap anything, i have to press the power button and then swipe to open it again, it is then fine after that.
also i have noticed, and i think its happening a lot when my tablet is a little angled using the case, the screen will be a bit jittery, where as my z1 is really smooth, and i also sometimes have to really tap icons a few times before they register.
i play clash of clans a lot and its been a bit difficult to play as troops aren't selecting as i am tapping on them.
has anyone got any advice?
I have done a factory reset to see if that would fix any issues from the fw update but its still exactly the same.
Thanks
James
anyone?

I installed the new firmware yesterday. While I notice an improvement with the touch problem it's still present. Just install an multitouch app (like this one: https://play.google.com/store/apps/details?id=com.easylabs.multitouch), let your finger trail on the screen and it's definitely obvious (the number on the top right should be the number of fingers touching the screen and it's often not). I tried the same thing on my old Iconia A500 and that's the one thing where it's WAY better than the Z2.
I don't experience anything as strange as you do though, it's mostly usable and I hardly notice it with the new firmware.
I did experience something very strange just BEFORE updating with one specific charger and one specific USB cable , the tablet wouldn't register any touch at all while it's was plugged in. As soon as I unplugged it it would work. The cable was fine with another charger and vice versa;
Weirdest of it all:
This happened while I was testing the output current for each combination of cable/charger and this particular couple was the one giving the "best" results; consistently between 1.1A and 1.2A
I can't reproduce this behaviour with the new firmware. All in all, it's usable for me. Biggest bug would be it not charging while playing power consuming games.
I have found mine goes more weird when it goes to sleep and i then wake it up, the screens sensitivity seems to be terrible, i have topress the off button and then start it again then its fine.
it will then mostly stay fine until the screen times out again then the same thing will happen when i wake it.
James: Same with my 521...
Touchscreen response was REAL BAD after updating to .402, then it went better and better day by day; strange phenomenon.
I also occasionally experience some touchscreen "numbness" after waking up the table with a double-tap, sometimes touch sensitivity suddenly becomes quite low just without any reason; touchscreen has problems detecting touches near the screen corners or doesn't react to touches at all. Solution: Switch to standby, and back on.
At the same time, the Android symbols (Back, Home, last apps) again become difficult to hit.
You can test this by slowly swiping your finger up from the lower bezel towards one of the symbols: If the touchscreen is ok, symbols get highlighted right after your finger reaches the lower edge of the symbol. If the touchscreen malfunctions, you need to move your finger up to the center of the symbols to get them highlighted.
So it smells like a software issue.
Touchscreen problems usually occur two to three times a day of normal use; so I regard it as acceptable - but the problem still isn't fully solved.
I would say it's a hardware issue which Sony attempts to counterbalance with software patches.
Just like on the Nexus7 (2013). There sfhub released a touchscreen fix which made the problem bearable for most users (with some experimenting with different versions of the fix, because each device is different).
I wrote a PM to sfhub asking him whether he could disclose how his fix works so that Z2 Tablet users perhaps could apply a similar, variable, tailor-made fix to their individual device.
No response, unfortunately.
Perhaps some of you could send the same request to him, and perhaps then he reacts?
every now and then, after double tap to wake, the tablet is extremely unresponsive.
I also just sleep/wake up again via power button and it's fine after that.
So my but feeling it's a software issue, not hardware issue.

I never had touch problems but after updating to the latest firmware, the tablet is unusable from time to time
what's annoying me is that Sony wont seem to admit that there is an issue, i was talking on their live chat to support and they said that's the first time anyone's mentioned that and isn't on any list of any known issues
Which doesn't fill me with confidence on how quick this may get fixed.
The speed in which is gets fixed may determine if i just send the tablet back to Amazon for a full refund, unfortunately i have bought the Sony case and magnetic charger now as well
I'm just really puzzled what to do, what can i do apart from sent it back if Sony wont even acknowledge they are aware of the problem and will release a fix soon
The only thing is because i have now bought the charger and case, i kinda want to keep it.
It was a direct replacement for my Z1 which i still have, and that is also updated to 4.4.2 now, but that shows no touch issues at all.
What's very interesting and revealing:
When Sony was addressed a few days ago regarding battery problems on Tablet Z and a few phones after the Kitkat update, they immediately reacted!
They readily explained that it is a problem with the Google Play Services running amok and that a fix will come.
But it seems that just because this here is a Sony problem (and not one for which another company can be blamed like in the above one), Sony simply doesn't react at all and obviously orders the service employees to lie and say that they haven't heard at all of a touch problem.
Boooo, Sony, shame on you!

HAHA ! Exactly the same in Germany. Even after talking about that issue with the SAME person three days in a row, I still was told the problem was totally unknown.
Later, I had a more private talk with one of the support guys. He revealed to me there was an order from Sony to tell callers exactly that.
Ah, as I thought.
This is abysmal behavior by Sony, period.
Also on the Sony support forum, none of the official support staff has replied to any of the topics about touch screen issues. It seems they are just completely burying their heads in the sand...
FW .402 didnt fix the touch screen issue. It is noticeably better than any FW from before.
Gosh, the touchscreen keep going back to home when i'm in a middle of fb conversatuion.
I was testing with chromecast +youtube: those swibe action to enlarge or fade out afe 99% imprecise...
Really wondering if I can return the item to amazon to fix this problem...

Are you sure you're not just accidentally touching the home button while typing? That happens to me from time to time, which is a downside of having the navigation buttons centered compared to having them in the corner like on pre-4.4 Android tablets. I actually think Google should add a setting to choose if the navigation buttons on tablets are in the left corner, centered, or in the right corner. Having them centered also makes it awkward to reach these buttons when holding the tablet with two hands.
Hey guys,
I got my Redmi note 2 yesterday and I'm having trouble with the touchscreen. sometimes it seems to be perfectly fine and sometimes it doesn't react properly. It seems to be worse in the right half of the screen. Sometimes I start scrolling and it works fine in the beginning, then the screen stops detecting my finger and when it detects it again, it opens the thing that my finger is on instead of scrolling.
I'm not sure if this is a hardware of a software bug.
Would calibrating the screen help? If so, whats the best way to do that?
I would usually try flashing a clean stock rom (the one it came with has some bloatware anyway) and test if that resolves the issue, but that's probably not the best idea if I decide to return it.
thanks for your help

Try entering in the MTK Eng. Mode, then go to Hardware Testing->TouchScreen->HandWriting and try drawing some lines crossing the point where the problem occurs.
A friend of mine had a Nexus 5 with a malfunctioning touchscreen, doing a similar test we noticed that there was a full horizontal line where the touch were not detected so every vertical line we were trying to draw were broken on the point where the bad line were crossed.
Obviously in that case it was an hw fault.
EDIT:
Reading your post again, it seems a behavior caused by lag, so maybe it's a sw problem and not an hw one, especially for the fact that "it opens things instead of scrolling".
Does it always happen in the same point/area? Or is it totally random?

I already did that and the results are very inconsitent. When I first tried it, it started drawing a line as it should, then it stopped and started again half a centimeter later, then it stopped again, and it pretty much went like that from top to bottom of the screen (at least on the right side of the screen, the left side worked better).
When I did the same test again, it didn't even draw lines, it just highlighted a few single pixels along the way that my finger was traveling.
And currently everything works perfect and smooth as it should.
It does kind of feel like a software-thing, but in my mind (correct me if I'm wrong) that should affect the complete screen equally and it just doesn't. I tried pulling down the notification bar earlier, from the top right of the screen and it just didn't work. I did a few tries and nothing happened. Then I tried pulling it down from the top left and it worked fine.
As I said it works fine at the moment, but I guess I'll make a few screenshots and a video of the problem, when it occurs again.
Ok, so the problem came back and I was able to do some more testing and make a video (sorry about the shabby quality, but it'll have to do ).
youtube . com / watch?v=rKsponNr9lA
As it turns out, the whole screen is affected equally, so I'm pretty confident that it's just the software but I'd still like to hear a second opinion.
The thing that kinda throws me off is that the reboot didn't help at all...
So what do you think? Is it just buggy software?
I'd try contacting the seller and explaining him the problem.
Maybe he will ask you to flash a new rom to be sure that it's a hardware problem and not something that could be solved without a replacement. That's what happened with my first phone from China.
If not, you could ask him and I think he will authorize you.

sounds like a good idea, I'll do that.
I just updated to this version, played pubg and looks a lot improved, anyone thinks they have solved, well i think so. Nowere in the log they have mentioned it being resolved, they had just posted abt the issue few days back saying fixed in nxt update
Looks like it has improved
Yes...it looks good. All my taps registered fine yesterday and game sound was also OK. It was not loud for some reasons but playable to some extent.
one strange thing happened though, i sprayed an enemy from very close but for some reason it didn't hit him, and i got killed, might be latency well not sure coz this never happend, no lag was there
It's still there. Maybe not exactly what you looked for but the ghost touch and multi touch jitter when moving with your right by holding down the left button is still there.
