A few issues/problems - Xperia Tablet Z Q&A, Help & Troubleshooting

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.

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

Or you need to update to .370?

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]After update to ICS touchscreen isn't accurate?

Ok so when I updated my tablet from 3.2.1 to 4.0.3 my touchscreen is no longer as accurate, ie when I tap somewhere its not always in the right place it might be like a cm out
I have tried calibrating touchscreen both ways but nada, I didn't have these problems on 3.2.1

Same issue for me.

same thing in my device (250gb 1.2ghz)
I am now back in 3.2.80, the only problem is that I return to only 512 MB of RAM instead of 1 GB.
Difficult to choose between a screen sensitivity issue and a RAM divided by 2.
I hope a soon update of ICS.
Hey guys I had the same issue with my 80 G9 classic and here is what I did to fix it I cleaned my screen completely and then I did the power and volume down button to get where I could force screen calibration OH MAKE SUPER SURE THAT YOUR TABLET IS ON A COMPLETELY FLAT SURFACE OR IT WANT WORK AND ONCE YOU HAVE DONE THIS REBOOT IT THEN GO INTO SETTINGS AND DO A SCREEN CALIBRATION AND A ACCELEROMETER CALIBRATION AS WELL MAKE SURE IT IS ON A FLAT SURFACE GOOD LUCK AND GOD BLESS YOU GUYS

Well, in fact, it did. ICS kernel is mandatory to get the full 1G with new Archos G9 ICS models. Honeycomb kernel will only enable 512M on these.
Yes , thx letama, of course it did .

Hi, I have similar problem, sometimes the screen stop working, it's not a freeze of the tablet cause the buttons works (volume up/down ON/OFF) but not the screen, sometimes even in the middle of using (i.e. writing a post in a forum).
Any idea? Obviously I have tried every touchscreen callibration I have founded...

He means he has a 512 device and he thought that it increased the ram to 1gig. Software cannot do that. Anyway, I don't think the 1gb models can downgrade can they?

I'm not going to reset my whole tab because a firmware update isn't 100%, it was 100% fine on honeycomb, no issues what so ever, and the fact others have it means its not my tab, and yes I have recalibrated loads on perfectly flat surfaces, going to email archos soon
Sent from my ice cream powered Nexus S
What's to say he only had a 512 device?
I had a 1gb device, it shipped with honeycomb and only 512 was available due to the kernel limitation.
After upgrading to ICS the full 1gb became available thanks to the new kernel.
When I returned to honeycomb the RAM dropped back to 512.
I've got this issue as well.
To test it, I installed some keyboard software that shows dots on the screen 'where you touch' and I did some testing with a capacitive stylus and was shocked at whet it reports for where I am touching the screen. To be honest, I never really used the tablet with Android 3.x as I upgraded right after buying it.
I will try the thing of booting into recovery and doing the calibration there. Might also consider going back to Android 3.x to see how the tablet performs.
-UPDATE- Ok I did the reset and calibrate thing and it did not seem to make a difference. I then installed a program called Touch Test from Android Market and did some testing. It SEEMS that SOME of the inaccuracy is being caused by me using a Capacitive Stylus (Griffin one). If the use my finger (which is way fatter than the stylus), I seem to get more accurate results. I've ordered a different stylus and will see how that works.

I have the same issue. I have used an Amazon Basics stylus and the ZooGue stylus and cannot even draw a straight line in Draw Something. It just feels like the touchscreen isnt sensitive enough even after calibration.

[Q] Do all Primes suffer from screen issues.

I am either returning my Prime today or trading it for another (one more time). I have had to exchange at best buy a couple of times due to the horrible screen tearing on the first one in gallery, camera and several other apps. Second prime the bottom of the screen died in less than 3 days and would never come back. Factory reset/ cold boot/ soft boot/ you name it. So now im on my third prime and i am still getting artifacts on my home screen and other apps. I have done the whole factory rest, install from sd, cold boot, soft boot, and nothing will stop this dang artifacting. Is this a common problem with the prime and i should expect it from ALL primes, or am i a victim of bad luck and should try another prime? If the majority has issues with this, i am returning it, but if the majority never experiences it i would love to exchange it and get a good working tab that i can keep. Not to keen on anything else until the S4 Krait hits tabs.
thanks for as many replies as possible as i hope to get a good number of responses so i can determine if its a flaw in all primes or just the ones i have had the fortune of using.
Thanks for your time!
Edit, here is a test that anyone with the app can try and reproduce.
C4 Here and have them happen sporadically and easily produced in several apps and launcher. Beautiful widgets is the easiest. I have been wanting someone to test this but haven't had any luck. Just set the beautiful widget forecast (last widget in the list of BW's) on any screen. tap the widget to access the animated graphics. If you location does not have the moving clouds change it to San Diego as it has been cloudy here for a couple of weeks. While the clouds are moving click either the clock or the recent apps button and usually within seconds you will start getting severe artifacts. I have been able to reproduce this on every prime i have gotten my hands on. I also get screen tearing/flickering in androbench pretty regularly but it is different than the artifact. My first prime, before i had it replaced suffered horribly from the left hand side of the screen turning static in camera and other apps. After that replacement my prime and those i have access to suffer the artifacts on .28 in several apps. Someone please try the BW scenario to a tee and give it about 30 seconds at most and see if you receive the artifacts.
I can't blame the BW app though as i have it happen more randomly in several apps, its just that i can reproduce it easily with the BW animation.
Added a poll just for stats.

mine stopped for now. ever since I did a manual reinstallation of the firmware & did a full wipe, only saw it 2 times on random occasions. Gone after a reboot.
p/s : b4 reinstallation & wipe, reboot wouldnt solve a thing. the damn problem sticks around

Thanks! That is exactly what i am after, just some confirmation that it is a wide spread issue. I hate being picky, but my unit gets them pretty bad and i am holding out hopes that this doesn't affect all primes. Im gonna update the OP with a test if anyone else that reads this can try. It almost always forces screen artifacts that can't be reproduced on any of my other ICS tabs or phones.
Thanks again!
Also, i did the whole factory reset, installed via sd, hard boot, soft boot, and nothing gets rid of them...

This issue is a Graphics Driver Issue (I'm 99% Sure). It was almost gone in .21 (I never had it). The graphic drivers was cleaned up in this latest patch, and after that some users have been having this issue.
It's just a buggy driver / incompatibility with some apps.
No ;l

not really. I had it maybe once or twice. it was either from an update or overclocking. the home screen icon and recent apps looked like it was glitching. I rebooted the prime n never seen it again. I wouldn't call that a display issue. Only a 1 time thing. never had anything like you described where bottom of screen or whatever died out on me.
Overall, I've been very satisfied with my prime display. its been performing fine for me. very responsive.

That gives me hope, I wonder if i should try replacing the one i have once more. The screen tearing is the only think keeping this from being a perfect pad for me. I get the tearing in androbench, my home screen, weather forecast and even when unlocking my prime. Also, after following your recommendations on improving performance, all i can say is wow, made it a new machine (-minus the screen artifacts that have always been there even on .21.) So, in your opinion, do you think i have a lemon and my problem is specific to my prime and should replace it? or do you think this is a common problem and should just return it?
Was very curious and decided to check it myself, but sorry mate, I wasn't able to reproduce it on beautifull widget. DO you have another app I could try to reproduce the issue ?

I have the same problem with Apex Launcher the left side of the screen starts to glitch and the only solution is to restart. It goes away for some time but after a while it comes back. I figured it's a software issue and just stopped using apex launcher. I'm curious if the problem is still there with some of the non-stock roms, but if it's the graphics driver I presume it's there ... Let's hope that with the next update things are going to be better.

The cheap solution when using Apex is to just rotate the screen, scroll and rotate it back... it will get rid of it

It only does it for me if the weather forecast is cloudy.( which it has been here lately) lol. Change your location to Miami or San Diego as they are having some bad/cloudy weather. Once you have a location set with "mostly cloudy" conditions, watch how choppy the clouds move when you click on the widget for the forecast. While the clouds are scrolling, open settings by clicking the clock in the lower corner, let it expand, and just wait. Within seconds my screen will start artifacting all over the place.
Also, thanks and thanked!
Have a BCOKA unit purchased in Dec 2011 (received in Jan) and have never experienced any sort of screen artifacts or tearing. BW weather forecast screen has been showing clouds flowing across the screen for 15 minutes now and still going smoothly.
I've never had tearing or artifacts and I have an old Prime (BCOKAS arrive Dec. 27th, 2011).
I did have all the blacks on my screen turn red (search for my thread) and had to RMA for that to get fixed but it turned out to be a hardware problem and Asus replaced my main board. I don't think this is a problemwith all Primes though. Maybe you'll get a better one this time. Good luck man.
The screen tearing is not the Prime's hardware - it's Asus and their incompetence in putting out decent firmwares. I can just about guarantee this is the situation. I had my Prime since launch. It had terrible screen tearing when I first got it. One of their early firmware updates just about completely solved the issue, and it was working great all the way through .21. Then, as soon as I installed the .28 update, the screen tearing and artifacting came back again. So like I said, it's definitely not a faulty prime (hardware wise). I'd suggest either keeping your Prime and waiting for an update that fixes this, or just returning it and getting another tablet.
As for some of the other issues caused by Asus using a garbage LCD, such as LCD mura (http://forum.xda-developers.com/showthread.php?t=1550530), screen bleeding, and dead/stuck pixels, that's another story.

I tried your BW test. the animations look and move great on my prime. I let it sit and no screen artifacts turned up. I did see in the options for BW that it said animations were an experimental feature and could cause possible issues. but none on mines though.
as for your situation, I'm not sure. I would say try exchanging again. but I'm starting to think if its maybe an app or combo of apps you have that's causing this. so this happens randomly, no matter what you are doing or app you're using? or is this only occurring when using certain apps or whatever? its kinda sounding like its your apps. did your prime do this immediately out the box brand new? or did this only start occurring after you installed certain apps or Widgets?
just curious, you don't have force gpu on in developer options, do you? that has caused similar issues before.
like previous poster said, I think this is a software issue. which will be solved through an update. maybe even try a manual install of update through Asus website. its a more thorough install.
After .28 I had some of this but none since words with friends put out the update. No doubt a combination of running processes, video drivers and in my case ezoverclock.
Not all Prime have this issue... however, there are enough that DO have this issue.
Just return the device.... don't decide based on what the "future" update will do.. or hopefully will do.
Don't even bother taking a chance.

Glad you are helping so here are the steps i have taken. I do a lot of research before i post as to limit the amount of time i need to take up. I too thought the app was an incompatibility until i went through the process of removing and formatting my SD card and placing the update zip from ASUS. Booted into what i would call bootloader and factory reset my prime. Once booted, i inserted the sdcard and the went through the upgrade process. Once done i skipped login and allowed the system to settle and then did a hard reboot followed by a soft reboot. I then choose to not restore my apps and only downloaded the BW widget. once opened and set to a location where it was cloudy, clicked the settings launcher and expanded by clicking the clock, which left the animation in the background and within 10- 15 seconds the artifacts became worse and worse. Entire sections of the screen would turn white or green for a split second. I removed the app and downloaded other apps one at a time and found that i would get the same flicker/glitch when using androbench. Also had and issue, when using the gallery, that the screen started scrolling white horizontal lines and slowed to a halt before rebooting. I recently had to travel to San Diego for a week, (poor me) and had my girlfriend go by BB and outright buy another tablet and as i couldn't trust the one i had and figured i would return whichever one worked (Money isn't an issue, just want this prime's display to behave.) Well, as soon as i unboxed it, logged in, allowed it to update, downloaded BW as a test and guess what, same flicker. Granted neither of these had the issues the first two Primes i had to exchange had, when half or most of the screen either went to static or completely quit responding/working.
Now to the interesting part. Both Primes in my possession when i returned home i could test further. I went through the same process of manually wiping, wiping, updating, HB/SB, FR yada yada and only installed the BW app and both Primes behaved the exact same way. As soon as i would expand the recent apps or settings overlay the screen would start to produce odd geometric shapes and would continue every few seconds (the flash is noticeable but quick). Now some good news. The prime i currently have was kept for a few reasons. THE GPS WORKS WELL!!! I have no issues with WIFI, 3/4 bars from70 ft connected to a Cisco 1262. Streaming Netflix with a set of slim JB Bluetooth headsets is a breeze. All of my games (Nova 3, Adrenaline6, Gun Bros, and multiple others play wonderfully and i can honestly say i have never had a game reset/ act funny/ or ANR. My browser would occasionally ANR but it wasn't too bad. The Prime i bought in San Diego would not get a gps signal sitting beside the prime i kept that was getting 10 satellites. Wifi on one prime was -84 in a location that my current prime gets a -66 with a 72Mbps connection. Games would force close on the other prime, Browser would just randomly close. SOD EVERY MORNING. So needless to say i returned it and kept the current one i have. I have tested all i know to test, and no, i don't have force gpu ticked. I have worked with Android for a while and have a Xoom running EOS that doesn't suffer any of the mentioned problems. (one heck of a tablet i might add). But as someone who travels a lot, and the work i do, this can be my laptop replacement.
So all in all i have a tablet that works wonderfully in every area except the fact that it will (at will) artifact/tear using BW animation. It will randomly artifact using Androbench, gallery, camera, quadrant, and both stock launcher and apex pro. Last and notable thing is it seems to do it less if i set the brightness to a static level, say 50%. All of this happens/ bone stock/ root/ no root. Currently running root with your build.prop, the atp app, and sio and this guy is rocking a lot better in the user experience (I/O)
Sorry for the rant, just giving all the info i have. No noob here and wish i could just unlock it and dive into it but cant do it as i don't know if it is hardware.
Thanks for all of the opinions and as soon as my thanking well replenishes i will thank those that i missed!

Bro, i know you have told me that and my gut says that what i should do as i have kinda been asking this same question in some of the other threads. Thought i would quit hi-jacking and create a post to just see how wide spread this is. I mean dang, i am on my 4th prim in exactly 30 days and only one of them functioned above 75 percent of expected performance. So scared that if i replace it again, i will be out of a 499 tablet as i will likely target practice with it with my 45. lol. Seriously though, i believe you got it right, too many of them have this problem. Sucky thing is i can seem to find an alternative that has what a really want, an S4 krait or a exynos quad and the same docking alternative that the prime has.
So you think there are primes out there that wouldn't have the screen issues i am having? I know i don't think anyone has said they have never experienced it.
Was this a problem when it was on GingerBread?
Thanks,

[Q] Odd touchscreen issue

My wife's P7510 has started to act up. The touchscreen is jumpy. When i go into the development options and use the pointer coordinates option, my finger registers as two,sometimes three. It makes it difficult to type, and just hard to use. Do i have a hardware issue or is it something I can easily fix?

Did you flash another ROM?
if stock: there is maybe moisture or dust, take apart as much as possible and hoover round the edges,If the touch screen is still not working, the tab is broken as the majority if touch screen phones and tabs cannot be calibrated
The tablet is still under warranty, so I don't want to dissemble. It had rooted stock OS on it, ICS. I flashed the stock rom back, and still have the issue. Did a Factory reset, and still have the issue. I am in the process of draining the battery to see if that helps. But I was hoping someone may have had this happen before, and can shed some light on my problem.
well, if you still got a warranty claim it then

Try using the touchscreen tune app (requires root).
This will allow you to modify screen sensitivity and test.
If you have the warranty..backup your data and claim a new one.

I don,'t think this app will work as this looks like a hardware issue after flashing another ROM, maybe you can check the all forum-searcher and check if anyone else has this issue too.
I'd suggest to send it back and claim a new tablet as well!

Touchscreen ghosting

Hi guys!
I bought the Z3TC LTE and are very happy with the device but I experience kind of ghosting with the touch screen:
Moving my finger up and down on an scrollable page / app it starts missing or skipping a movement!
Is that a general problem or should I return the device?
I made an demonstration Video:
http://youtu.be/EUeAt1HMt-w
try a reboot.
is it only 1 app or is it happening on different apps?
Reproducible in every App! Reboot does not help!
If I find time I'm gonna try the same on an Z3TC in an local store..
hmmm thats strange....
glove mode is not on right?
If not, try a factory reset.
if that does not work, sounds like service.....
does this happen when you are charging the device? sometimes this is caused by a charger that doesn't supply sufficient current
Sent from my HTC One_M8 using XDA Free mobile app
I think I am facing the opposite of that. The screen is far too sensitive and sometimes takes a scroll as a touch. Happens everywhere on the device. I fear it's a hardware thing.

Nope! Glove is off! Did factory reset! No change, directly reproducible!

does this happen when you are charging the device? sometimes this is caused by a charger that doesn't supply sufficient current

Happens without charging!

I think I am facing the opposite of that. The screen is far too sensitive and sometimes takes a scroll as a touch. Happens everywhere on the device. I fear it's a hardware thing.

Exactly that made me aware of the problem! Did you try what I did in my YouTube video?
I have tested an black Z3TC WLAN in the local store! Could not reproduce the problem! Gonna send it back, keep you updated!
I had a similar problem for a couple of days.
The tablet would scroll up and down on web pages erratically and also when using the keyboard it would enter words independently.
The issue resolved itself after awhile so there is nothing I can suggest to fix it.

Mine also typing by itself (when battery below 20%)
I had the same issue and end up got a replacement from vendor. They didn't do serious check and question me as usual. Then give me another one.
it makes me feel this is a common issue with this tablet.
Mine works perfectly fine

I have this but it's not static. It was happened from time to time, both vertical and horizontal scrolls.
Also the replacement tablet has the problem! Could you guys please write which model you have? Might be LTE related!?

Audio and screen issues

I come from a Nvidia Shield K1, which i was able to get a full refund on due to screen burn-in, basically upgrading to the 10.8 LTE version for 150E. Amazing deal, right? Not quite.
I mostly play rythm games on Android, and, as it turns out, this tablet seems to have serious compatibility issues with them. Playing around with the timing settings only goes so far, as there seems to be a constant delay between my inputs and their audio feedback, which, as you can imagine, inevitably throws me off when things get hectic.
In addition to that, certain notes in certain songs will ALWAYS drop, no matter what. I activated the touch screen visual feedback in developers options, so i'm 100% sure the physical tap isn't being dropped. As in, the tablet is still registering the touch, but the app for some reason "thinks" i lifted my fingers. Multitouch test also shows no issues, up to 10 simultaneous, swiping taps are registered and maintained for 30+ seconds with no fail.
On to my second point, is the color fidelity supposed to be good on this tablet? It seems to me that the "Vivid" setting oversaturates colors, especially in the red spectrum, while the absence of it makes everything look washed out. Ultimately, i couldn't find a setting i was happy with, so i did some research, and found out that most tablets include a sRGB option, since apparently android apps can't handle color accuracy well. This tablet has such option, but guess what, everytime i try to turn it on, it turns itself back off as soon as i touch any other setting or change menu. I'm not sure whether, were it working, this option would fix the colors in a way that satisfies me, but at least i'd like to try.
Did anyone else experience these issues, and can they eventually be fixed somehow? I honestly love the general look and feel of this tablet, but i'll reluctantly send it back if not, as they're a dealbreaker for me.
Regarding the audio issue, i did a side by side comparison with the Shield K1, pressing the same button in the same app, at the same time.
The M5 would sistematically lag behind by what i'd estimate between 100 and 150 milliseconds. This seems to happen in every app i downloaded from the playstore, but video playback of any kind isn't affected.
I didn't really notice at first, but now, knowing it's there makes it very noticeable, and everything feels sluggish. Could someone be so kind as to test this on their device? Maybe i just got a defective unit, but i highly doubt it.

Which Android Version is the shield tablet running!?
Sent from my HTC U11 using XDA Labs

OK so I've none of the issues described, but am running the M5 Pro version in my end. Can't comment on the standard variant though.

Thank you for taking the time to test. I'll have another one sent within 2 days, let's hope it was just a weird fault, though i still doubt it. I will update when it gets here.
Edit: changed my mind and went for the refund instead, will most likely give the 8.4" a shot next.
Where did you order your tablet from?

At least now i'm sure i'm not crazy.
