Scroll lagging and difficulty tapping - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Hi all,
I just unboxed a new Xperia Z2 Tablet and i've had some trouble with scrolling. I previously had an iPad and currently use a Nexus 5, and i'm used to two things:
1. Scrolling is easy and responsive - ie the screen moves with my finger, which I guess is the point.
2. I tap where I intend to tap, and the app responds according to what i've tapped.
Neither of these are happening with the Z2. I've still got faith. I figure i'm doing something wrong though. Any thoughts?
Thanks!

Please update the firmware to the newest one (last characters are .402) and see whether the problems are gone. Earlier firmwares are known to have touchscreen problems.
You can use the Sony PC Companion software for your PC to do the update if the tablet doesn't show availability of an OTA update. Or, if both don't work, flash a FTF from this forum via Flashtool.

i still have this issue even with .402
not sure if i am going to send it back and get money back, not surew how long it will take to fix?

I'm in the same boat. Still not great with the firmware update. Sounds from other threads that there are others looking into it too and Sony aren't helping... Not sure what else to do. Except wait...

Send it back, accompanied by a peppery letter that Sony's service is abysmal and that you won't buy another Sony device.
Write in the letter that you KNOW that Sony's support employees have an order to deny the existence of the touchscreen problem and that such a behavior is incredibly impudent and the opposite of service.
They must start to know that the customers don't accept certain things, period.

I don't have any of the issues you have mentioned. I'm on. 402 too, I have so many things running and sitting at 900 Mb of free ram with complete zero lag. Still have touch screen issue but it's not as major as before. Probably happens every three days or sometimes just none. have you tried repairing it with Sony update service or Sony pc companion? Try those, and before you do that go to settings / back up and reset and do a factory reset.
If the problem still persist then exchange or refund it.

I too have the impression that there are less ignored taps when doubletap to wake is disabled

Actually I own z ultra and a z1 compact and a z2 tablet
Ultra: no problem at all
Z2 tablet, leggy, unresponsive. I'm trying to sell it on eBay after 3 weeks
Z1 compact. Near unusable. Too much sensitive.

ps I got my xperia s on the 9th March
Thanks for the reply, seems I was a little too late! I also received my Xperia S on the 9th. Oh well, guess that's more money I have to spend...
I don't understand how, but I just received my SmartWatch (MN2) from MobileFun in the UK. Nobody has stock and MobileFun still say they don't have a confirmed release date...yet here I have one this morning delivered. I think what may have happened is that stores were given single units to display prior to the main release, and as MobileFun is an Internet retailer, they just passed it as normal stock! It was sealed and had never been used before.
Now I am not using it with a Sony phone. I have an HTC Evo 3D. Although it is working, I have hit 2 issues already
1) This phone is listed as compatible, but the email notifier does NOT work with HTC phones. All other apps, like text, calendar, call log, music player, weather , facebook and twitter do work fine.
2) If the bluetooth connection is interrupted for any reason, such as moving out of range, sometimes it does not resume correctly and the watch ends up in an infinite loop trying to reconnect to the phone. I have to kill the processes on the phone to reset this.
It installed a firmware update when I first installed the Liveware and Smartwatch application on the phone, so I am sure there will be further improvements for things like this in due course.
It says it includes a USB charger on some websites. It does not. It just includes a unique type of USB cable that you have to plug-in to a generic charger or computer.
The touchscreen works quite well, but the image is not that bright and there is a yellowyness to the colours. Swipe up to move to widgets, swipe down to move to app icons, swipe across to move between pages, and use two fingers to go back up a level! There is no speaker in the Smartwatch but it does vibrate. The screen resolution is adequate but limited.

Thank you for reporting. Great to see your micro review with key issues listed. Now, about the bluetooth, I just have to say I'm flabbergasted. Sony Corp. have had A COUPLE OF YEARS to get this right since the LiveView and they still manage to screw it up. I'm sorry, but it just isn't acceptable.

I am not sure, at all. The LiveView received few and poor updates. Further improvements - well they cannot even get the basic functionality right so they shouldn't release it. I do hope you have a non-release version. This is appalling.

Yes the vibration alert is key. Shame they haven't got the Bluetooth right, though. I would have got a Motorola MotoACTV. At least they do upgrade the software every few weeks, BUT it lacks that one crucial factor the vibration alert.
Still hoping Sony will correct things before release.
On sonymobile sweden homepage the smartwatch is listed as "New" now, before is was listed as "coming soon", i think it was today they change that.
Sorry for my bad english.
Guys is it that bad
or are you so demanding
I was hoping to have fun with some accessories for Xps.
But now i very concern about it IS IT WORTH's IT since i dont want to put my money on the mud
Cheer up
seem's that sony wont get any more profit from me !!! Too bad SONY
I also got mine from mobilefun. Works well except for email notifications with LTE galaxy note. I get a device not supported message. It does reboot a couple of times but auto reconnects.
Battery life is good so far, I am pleasantly surprised. It also looks good.
It is quite good. It just isn't super reliable yet with those odd disconnections. The more apps you add in the more it does those random reconnects. The hardest test is the viewfinder app which really stresses the Bluetooth connection. The mail app will only work with Sony phones. Just have to hope someone develops an htc one. Battery life really is good.
I preordered mine and it should arrive 5th of April here in Germany. Since I have learned that BT-issues may be caused either by the gadget and the phone itself I give it a try.
But as an old Sony-victim (MBW 100, MBW 150, both dead short after the 2-years-warranty), I will return it immediately for refund when BT does not work properly.
Give you a report as soon as I have my hands on it.
arrived a bit ago
mine arrived last friday,
I'm semi impressed, but to be honest I don't think they should have called it a "Smartwatch" i think Smart Remote, or Extended Display would have been more correct.
1. if it doesn't get a BT connection to a phone it will not do anything,
2. if it looses the link ( phone with dead battery, turn off bluetooth to save that last bit of battery you have left ) it has a fit and will loose time eventually flash's the time then goes to a connection type screen like when you first got it.
3. VERY FEW USEFUL APPS, yes new events, and social network apps are working but aren't really over the top, the ViewFinder app sadly wasn't even done by sony yet in the original Live View the same feature app existed made by sony. what gives? there are only a handful off useful things for apps and gmail notifier isn't one of them. it just says if you have a mail and how many unread , doesn't tell you anything more. so really it's a bit of a letdown.
All in all i'm fine with it, and i put up with it, but I see why now some of the standalone android watch's are more expensive. can't say IMWATCH would be any different but i suspect it would be as it has storage on it suggesting you can load a few things and run it without the bluetooth but if you wanted updated info then it would need to re-link to the phone. this would be much more attractive then what sony did. so hopefully they'll catch on and at least allow you to keep TIME and maybe an onscreen setting as to 1 bluetooth on/off to save battery and just use as a watch sometimes, ( maybe an app? ) and have it not go into dead mode. fair enough if you power it off it loses everything and will require linking to the phone. Also MULTI DEVICE WOULD BE NICE, i have more then one android device that can run the software thusly if i want to take my Galaxy Note one day, my HTC SENSATION XE another, or my p920 another day, i should be able to choose which one i want to use with the phone that day and not have to keep re-pairing it. just maybe they can limit it to one connection at a time bt remember maybe up to 4 paired devices ( or at least 2 )
( meh why rant here as Sony never reads here mosta the time anyway )
Received my free Smartwatch from Phones 4 U today. Not had chance to play with it yet to give a review but thought I would mention as it would seem the accessories are now becoming generally available.
where are you guys buying these in the uk? Cant find any retailers
He's got one, and he's made a little video on it.
You can do some great things with the watch, seems cool. Hopefully when more apps start to pour through it will get even better
I just receive mine this morning.
A gift from thephonehouse with my Xperia S
Some basic apps from sony works perfectly.
But other apps (japanese most of them) working as they want...
Like an app : it command your camera and you can see in your watch live images. This apps launch your camera or not
A workaround to enable email notification on non-Sony phones with the new SmartWatch - note requires knowledge of Tasker.

A few issues/problems

I just bought my Z today and am having a few issues with it. First, the automatic brightness doesn't work. That is if it is turned on/off from the menu bar it does not work at all. If it is changed within settings the brightness does change to a certain level and that's all it does. Second, the tablet is extremely slow installing some applications. I have owned many different android devices and never experienced the absolute slowness this tablet has when installing some apps. Not all apps install slow, but I had one take over a minute when it should have taken about 5 seconds. And finally when using the browser, the touchscreen becomes very unresponsive when downloading and installing applications. I try to scroll by swiping the screen and sometimes the tablet just completely misses seeing that input.
Edit - I tested the auto brightness some more and it does work, it's just not as sensitive as some other devices I am used to.
Edit2 - I think the slow install could be a bug with the custom skin Sony uses on top of the o/s. It's sometimes getting 'stuck' displaying the install message.
Rob
If you've just bought it today and you haven't too much stuff on it I'd try a factory reset and try again. I have had three different models of Asus tabs (all rubbish), still have my original galaxy I/O tab (great for its age) and I can honestly say this is the most fluid and rapid tab I have seen.... That includes installing apps which as soon as I started using it caused me to remark how quickly it downloaded and installed from the play store.
Auto brightness is also sensitive and rapid on my unit, to the point it annoyed me at the beginning cos i thought it was too sensitive...
If that doesn't work maybe your unit is faulty

Worth a try but still think it's unusual for him to have these problems. For me the benefit of 370 upgrade was screen sensitivity improvement, the app install problem was not apparent either before or after upgrade

I returned the 16gb model and bought a 32gb instead. I think the auto bright is just less abrupt than I am used to, but it does work. The only problem I am having on the 32gb which I did not have (or notice) on the 16gb are the 'phantom touches'. Twice today the tablet went into the settings all by itself. I'm going to research this issue more....

Hi Rob, there I would recommend latest software for the screen sensitivity and if that doesn't cure the problem I'm sorry to say that it could be a faulty digitizer, so back to shop again

[Q] Flex and ghost/phantom touches

I just bought a SGP311 (US Wifi 32G). When researching what tablet to buy, I did see some reference to phantom screen touches when flexing the screen, but I think the video said it was cleared up by firmware updates.
Mine is running .370, which I understand to be the newest available for the SGP311 (25 Aug 2013).
I find the phantom touches so sensitive and terrible that I can't believe there is not more stink about this on the internet. For example, if I'm holding the tablet with two hands and reach away with one hand, the resulting pressure from holding the tablet with the other hand causes touches all over the screen, wreaking havoc on whatever I'm doing. It even happens if I push "too hard" e.g. when playing a game excitedly.
Do I have a particularly bad unit for this? Is there a way to fix or mitigate this?
As it is, I don't think I can keep it - it's just too frustrating to use. If I hold it lightly and with two hands it's fine, but anything else - there's a high probability of touches all over the screen, especially in the Back button area
Mine doesn't do it. Or I'm not holding it "incorrectly"
Can you link to/upload a video showing this behaviour? You may want to turn on developer options->show touches to get an idea of what touches the device sees.
I have the same problem as the original poster...
Bought mine today and was messing around with it. Then I noticed the tablet 'doing stuff on its own'. After a quick test I realised I could reproduce the error by holding it in landscape and twisting it slightly. This resulted in either the back button being activated (lower left corner activated / pushed) or the settings notification area popping up (lower right corner activated).
So I guess they should have used a stiffer material as the back cover. But then again it seems almost inconceivable that the testers wouldn't have encountered this issue, if it was universal... so I'm guessing that our units are faulty - sonofabitch!
At the same time its my very unqualified guess that it isn't something which can be fixed by new firmware.
Edit: Just thought of something ... perhaps thats why the UI of the new firmware has changed? No more 'buttons' in the lower corners (as far as Im aware).

I had these same issues with mine when i got it but the update did actually fix mine so its possible that, if you are on the 370 update, that yours is extra sensitive. I have done quite a few flex tests to try to make it happen again and just can't get it to repeat after the update.
I would contact either the place you bought it from if it is within the return/exchange policy or Sony and exchange it.

Im using 10.1.C.0.370 - tablet came with that installed.
For once I actually bought electronics in a physical store (5mins walk away) so I'll go there and get them to replace it - and also test their demo model.
The demo model had the same issues. It also seems the issue is quite widespread judging by the Xperia tablet Z support forum.
The same happens un my LTE 16Gb .244 black versión...
It happens ramdomly, above allí while attached to Power stock charger, but not always...
If Sony doesn't want us to unlock bootloaders and install other ROMs tan stock, why they release such a crappy firmware?
It also happens in my c6603 sometimes un the same conditions as my Tablet, so i think is firmware related
Sent from my C6603 using xda app-developers app
So that's what's happening
I am having the exact same issue, in fact I didn't realize it was the flexing that was causing the issue until I read this thread. Now I can reproduce it consistently. I am so bummed, I LOVE this tablet, Sony has a lot of great stuff they put into this tablet and the form factor is amazing. I am pretty disappointed though because this makes it pretty hard to use. I checked and I am running the latest firmware. For what they charge for this thing you would think it would be a better piece of hardware. Back to Best Buy I go I supposed.

Mine is doing it right now! And I'm not even holding it, it's Sat in its dock. Mostly on the right hand side of the screen and bottom right corner (in landscape mode)..kk
That capital S of sat, and the ..kk above was done by these ghost touches.

Oh, by the way, mine is on the UK generic feature 244 which I flashed with flashtool, I would go back to the original t-mobile 're, but the ftf I made before I flashed th 244 doesn't work. I would be most grateful if anyone here has a tab with the original t-mobile fw, and could make an ftf of it!

Spanish unbranded FW... Seems that the problem concentrates on navigation bar, but not only... I have the visible touches enabled on developer section of settings, and can see the ghosts...
Seems that i have to unlock my bootloader and flash CM10.1 or 10.2, and see if they exists as well...

Its really noticeable on 4.1.2 and 4.2.2?
It seems to be main reason to not buy this. ;/
My brand new Tablet Z running 4.2.2 is acting out aswell. When in portrait mode, it seems obsessed with ghost tapping home or return...
Edit: Turned screen "logging" on. Dammit, the screen goes haywire at just the tiniest bit of flexing - even when NOT flexing... Sigh.
I've gone back to the correct fw for mine and it's settled down a bit, it still does it now and then, but nowhere near as much as it used to.

I got my XTZ and it works just great! No ghost /phantom touches at all using stock 4.1.2 even when i move harder the tablet. I think everyone who experienced this should replace tablet with new.

Actually got my Tablet Z replaced at the Sony dealer, no questions asked. (Kudos for service!) For some reason the new tablet seems to be doing much better than the "old" one.
I got 5 of these in for our staff - 2 of them have the same issue.
Phantom button pressing happens when not even touching them! Going to try and swap these over..
Running 4.2.2 on black LTE version in Australia.

Experiencing random clicks and lags.

Get to XZU today. First experience is about some light lags..
the model is the eu C6833 with FW .532
lags are not so terrible, but facing like my Xperia Z (standard, not Z1) i notice some less lagging into Z (C6603)...and thats curious, because i read around that the Ultra has no lags at all! So i was quite suprised..
Even during the startup, starting both phones, can be noticed on the Z standard the coloured stripes passing in a much more smooth way... instead on the Ultra.. they are quite lagging some... i know, that means nothing. I just asking about other experiences..
But, another problem, and this is not just a lag feeling... while using the phone (the ULTRA)... occasionally it shots here and there some clicks... is not happening continuous... just it may happen a couple of time in one hour.. for example.. while i am tiping.. just some character jumps out.. and maybe the keyboard goes away..then suddenly return after 1 or 2 seconds.. quite weird..
Also.. i figured that may be a common problem related to youthness of firmware?
I got the device today.. so, i may return it for replacement to the store asap, if i figure that may have some defects.
Suggestions?
MANY THANKS!
The current firmware is not even close to being bug free, so weird stuff will happen, but if you can't live with it i would get a replacement and hope for the best. It's all software bugs though, so you might end up with a new device that's similar to the one you have now.
Sent from my Z Ultra, using XDA Premium 4
ah well..its ok i can wait.. i just was not sure if was a software youthness defect, or a hardware defect. That may be quite different, because after a week i can not return the phone to the store, so if a hardware issue came out, i would have to send the device for service and wait "who knows how long" to get it back...(and maybe, having the problem still there..)
I'm not experiencing any lag, but my screen is more sensitive after i updated from 510 to 532, which is a thing that i don't like, and it results in a couple of random taps that i don't want. This showed up for me after the 532 update, so it's a software bug. One thing i would do if i were you is to use the diagnosis tool (Settings->About) and test everything and see if there are any hardware defects; just to be sure.
I'm thinking either the screen is overly sensitive to your inputs or you might have had it connected to a charger at the same time?
Depending on the quality of the charger, this can play havoc with a capacitive screen and I have noticed odd behaviour on cheaper chargers since getting my first capacitive screen phone and almost every device I have had since can exhibit this behaviour, XZU included.

Is your C6833 from one of the carriers, which might have bloatware (a possible reason) , or is it contract-free standard Sony?
Your comment about the boot up image caught my eye. The purple wave/swoosh at bootup really lagged on my C6802 when I used backup/restore to go back to previous settings with different firmware. A clean re-install solved all of it.

Oh no i never use devices while keeping connected...btw the xzu..is supplied with original charger...i see no reason to use a cheap blotty charger with it.. I guess you are right about oversensitivity..i applied a film protection on the screen and i am noticing much less random clicks...
But i sm still evaluating the return policy of my store..to go and get another one.. Just dont want to lose time if this are software issues..

The Diagnosis tools, reported all "OK" except the flash. I guest because there's no flash..
I just repeat. That lags are not aggressive.. but the refresh is quite far from that i've seen in youtube reviews.. i would say, same performance like Xperia Z.. and that's nonsense because one is Snap600 at 1.5ghz and XZU Snap800 a 2.2ghz so, it MUST be, more reactive..
AnTuTu v4, reported 34000 anyway. And the reliability test passed.

Is your C6833 from one of the carriers, which might have bloatware (a possible reason) , or is it contract-free standard Sony?
Your comment about the boot up image caught my eye. The purple wave/swoosh at bootup reall
y lagged on my C6802 when I used backup/restore to go back to previous settings with different firmware. A clean re-install solved all of it.

It is unbranded device..there is some bloatware..but not more than the usual in last Xperia..like mcfee.. Linkedin..filecommander and a couple of tools..but the boot time is substantially higher than those seen in youtube video reviews..
Apparently one thread is insufficient for this issue...

Multi touch issues?

Hello everyone, I just got this tablet today and I'm having an issue with it. I was trying to play a music game and I noticed that when I touched both extremes of the screen the multitouch would release my fingers for some reason. I've recorded a video of it using a multitouch application just to make sure I wasn't going crazy, here it is:
Link to the Youtube video
Do you think it's defective? If anyone has this M5 10 tablet could you test it for me and see if you also have the same multitouch issue? Since I just got it today, should I return it? Or is it something that can be fixed?
Thank you.
Received mine today from Boulanger in France, i used the same software as you to test it. Everything is working fine, even with 3 or 4 fingers, using the same kind of routine you used. So i suppose that your tablet is faulty. Sorry mate.

This stuff happens Thanks for testing it out! This one is going back
I have the same problem bro! You can find my post here: https://forum.xda-developers.com/showthread.php?t=3777471
I have already open a ticket on the support

I have the same issues als well. You can see it very well with the App "Multi touch test" from Spencer Studios.
Has someone more info on this issue as the tablet is useless for me with those touch problems and I will send it back if there is no fix available in the near future.

Hi Andrgin, which is your problem? In my case I have the problem only if I touch the screen with two fingers. In this case seems that the tablet, after 2 sec, can't recognize anymore the touch. I'm waiting the response of the support for the ticket that I opened, hopping that they can tell me that is only a software problem and not an hardware issue, let's see...Anyway I have your idea too, I bought this tablet to play music game and is really useless with this problem.
When I touch the screen with 2 fingers at the same time and do not move them for about 1 second the tablets looses the touch of both fingers. It does not happen if I dont put both fingers down at the same time (more than about 500ms), move the fingers around while they touch the screen. Also it does not happen with 3 or more fingers.
To me it seems like the system treats the as a gesture.
I made a video about it:
youtu.be/PXXakOw_1Hk
I also thinks that the system treats this as some kind of a weird gesture. I don't think it is related to the hardware. I'll ask the Huawei support soonish because it really is annoying with cytus 2 for example or even pdfs when you want to pan soon and have 2 fingers on it and then your touch input gets removed.
This is with the 10 pro
Could it be, I hope that you are right but is really strange that only some devices have this problem, if it is a software problem, all the devices with this software need to have the issue.
I think all have this problem. So far everybody that said he does not have this bug had tested it the wrong way. You have to place both fingers at the same time and do not move them. If you move them while touching the screen it still works.
And no I dont think it is hardware related.
I also experienced this (talked about it in another thread), but it must be more complicated than that.
It's not something that systematically happens whenever i put two fingers down a the same time. It works just fine most of the time, but occasionally notes will drop, always in the same spots, in the same songs. "Pointer location" shows the touch is still being registered, if that's anything to be trusted.
I'll take the occasion to ask again since there seem to be other people who play music games in this thread: beside the touchscreen issues, has anyone noticed a slight delay on the audio feedback? I'm talking about a 100-150 ms delay from the moment i touch the screen to the moment the corresponding sound effect plays. The touch itself is registered correctly, but the audio lags behind for some reason.
Either way, i sent back the 10.8", gonna have the 8.4" here by tomorrow i hope, will update on how this one behaves.
It does not matter where you place your fingers only that it happens at the same time (less than about 500ms) and you dont move them for about 1 second.
About audio I dont know. Most time I had sound off.
It may be a general Android Oreo bug, although the article speaks about Android 8.1, not 8.0:
https://www.xda-developers.com/android-8-1-oreo-multi-touch-bug-fixed-june-update/
Maybe Huawei used parts of Android 8.1 for the M5.
A fix from Google is planned for the June security update.
Just tested the 8.4", after installing the new update. Interestingly enough, it didn't seem to drop any inputs.
The sound delay, however, is exactly the same, and it baffles me no one else seems to notice it.
On top of that, i think i got a defective unit, as the charging speed starts off at 3300-3400 mAh, then drops to 500-600, never to rise again. So much for quickcharge.
Battery also seems to run considerably hotter for no apparent reason: 37 degrees Celsius while charging at that pitiful speed, no other apps running.
For reference, the 10.8" never exceeded 32 degrees, and that's while charging at max speed, with apps running at the same time.
Overall, this tablet has been nothing but a huge disappointment, i'll just refund it and wait for something else to come out at this point.
Edit: it charges normally when the screen is turned off. When the screen is on, the charger seems to provide enough current to offset whatever i'm consuming, plus those 500-600 extra mAh, so no matter what i'm doing that speed doesn't change. The 10.8" was charging normally, full speed minus whatever power i was drawing, so i'm still pretty sure something's not right.
@chris_g I really hope it could be the problem but wait two more months it's really frustrating! For now I haven't received yet one answer from the support...
Not really good news from Italian support, them tell me that no reports was received about our problem, so them suggested me to try to reset the device to the default to see if is a software problem. Did you guys found something else? I'm really thinking to request the replace of the device.
Just to be sure, could someone give me the mail of the international/English support? I want to try to write a mail also to them.
Cheers
I got the M5 Pro from amazon.it and the warranty check showed that I get warranty in most European countries. I opened a ticked with the Austrian support providing all the info they needed. They said they dont know of the problem so far and will forward it. This was over 1 week ago and I did not receive any response yet.
Replacing the tablet will not solve anything because every M5 (at least the 10" versions) have this bug.
And no it is not an Oreo bug because my Mate 10 (also EMUI 8.0) works fine. I guess it is some code Huawei added to support the pen.
Firmware Finder already shows a EMUI 8.1, but it is not approved for installation yet. I guess we will get Oreo 8.1 in a few weeks/months and this bug will hopefully be fixed in the new version.

Don't be so optimistic on that one, as Google themselves introduced an all new multi-touch bug in the 8.1 base. Thus one bug will maybe just be replaced by another one, as Google already stated that they'll have the bug fixed in the June update soonest. Let's hope Huawei uses the patched June base to upgrade our tablet to 8.1.

Huawei already ships Android 8.1 with the P20 so I guess we are getting the same code. I never heard about multi touch problems there so I guess Huawei has already replaced that faulty Google code. With all the people complaining about late Android updates for existing devices, but there is a reason most vendors wait until they release a new Android version for the masses. Google phones are simply beta test devices.
I have the 8.4" wifi model. It suffers the multi-touch problem but not the sound delay problem. I tried the drum pad app, sounds play instantly as soon as I touch them.
