Screen judder? - Nokia Lumia 800

Anyone else noticing screen judder on their Lumia 800? I'm specifically referring to, for example, the screen jumping up and down a little whilst my finger is completely stationary on a list - such as the People feed.
It was present before the 8107 update and still present since (though it does seem to have been reduced).
Wondering if it's a firmware issue (my Omnia doesn't do it, so it's not a software issue) or hardware.

I have exactly the same issue. Is it not meant to be like that then? Does this class the phone as being defective?
It wasn't as bas for me pre-8107. Now that I've updated, it's a lot worse...

Lol. I'm pretty sure it's not meant to be like that, no. I don't know whether the phones are defective or whether there's a bug in the firmware.
Casey

yeah, same here...

It's a known issue but has never been acknowledge by Nokia:
See here:
http://www.mobiletechworld.com/2012...a-800-firmware-update-doesnt-fix-most-issues/
and here
http://discussions.europe.nokia.com...-Strange-UI-Behavior-after-Touch/td-p/1221503

Weird. After a hard reset (hold down power button for 10+ seconds) it's not happening to me anymore. I can keep my finger pressed down on the screen and everything stays still.
You should try it. May work for you...

Nope that's because your device is hot. The colder the device /screen (and finger) is, the more pronounced is the issue. It's an electric (grounding) issue.

Mine only does it when it's plugged to the mains.

I also had it with my HTC HD2 with Windows Phone 7.5... I think it is a grounding problem, and the OS that is very sensitive to this sensor \ electrical system.

From those links it seems that a HTC phone had the same issue and that HTC were able to reduce the effect with a firmware update - so let's hope the same is true here.

[Q] Touchscreen unresponsive stripe - digitizer problem?

My Atrix's screen has become unresponsive in a vertical column (if the phone is in portrait mode) that lines up about with the W, E, and S keys. Restarting fixed the problem for maybe 20 seconds or so after the phone became usable, but doesn't seem to have made a difference after about the third time or so. I also removed the battery and held down the power button for ~45 seconds and then put everything back together, which also seemed to have helped for a minute or less before the stripe became unresponsive again. I also restored to yesterday's backup a couple different times (CM 7.2 stable), which also temporarily helped.
So after a brief search, it seems that the digitizer may be the issue. Is there any way to tell for sure? At first it seemed like a software problem, but it could also just be the digitizer acting erratically because it's going out, so I'm not really sure, and I'd rather not attempt a repair that may not be necessary.

there are some screen tester apps on Play which you could use to see if, in fact, your digitizer is a problem.

Do you have any specific recommendations? I downloaded the touch test app from here (http://www.freewarelovers.com/android/app/touch-test) to see how much of the screen was misbehaving and discovered that it was a perfect stripe the whole way down, but because I'm not terribly knowledgeable about troubleshooting phone hardware, I don't know if that's telling me it's the digitizer or something else. I attached a screenshot that shows where the stripe is.

From what I've seen on here it does look like your digitizer is at fault. I have never had to change mine but there are plenty of posters on here who have and you can look at their experiences to assist you. Also, here's a video I found so you can see what you'll have to do. Good Luck!

[Q] Touch response during charging

Yesterday I purchased this awesome phablet but I found few bugs.
I already updated to 14.1.B.1.510
1) screen of death -2 times.(volume down + power key help me to reboot)
2) Touch response during charging is very weird..
3) I never saw such a ugly camera.
So I Want To Know Should I Replace It OR its software fault
54 views but no response. Friend please let me know this is hardware fault or software fault.
When I put my mobile on charging screen touch becomes less responsive.
Anyone facing this problem
Please reply me it's very costly mobile...
And is there any permanent solution for SOD.( screen of death)
1. Try ticking the optimized backlight setting, or turn off adaptive brigthness, or factory reset, or repair via pcc. Or claim warranty.
2. No not for me, still sensitive enough I don't see noticable difference when charging. Try charging it in different place (other than your home or something) or try using another charger.
3. Yes, downright ugly.

2. I remember reading about a lot of Note owners having trouble with the touchscreen while charging. Not sure if it got fixed through an update, but it never got mentioned again (as far as I know), which has to be a good sign?

From the first day it was reported no one truly knows whether it was software or hardware. Firmware update seems to make a lot of reports die down, but not all - making it likely to be software. The trigger seems random and varying it suggests it could be hardware for some.
Hell, no one knows. I never had sod in my old fw (461 and 475, but I used it only for a very short time) but on 510 (wiped clean) I do experience occasional "fake death" issue, but I only need to press the power button two times max to wake up the device. So well, maybe its not even sod.

My previous phone was huawei with amoled, and the sensitivity while charging was very bad. Turns out every device was like that. My zu isn't, clearly. Wonder if the OP's case is really that bad.
Sent from my C6802 using xda app-developers app
I currently use the Galaxy Note 1 running on Jellybeer (custom ROM) and will be going for the Ultra LTE (100% sure no backing out.. lol)
2. Weird touch behavior while charging is present on the Galaxy Note.. I am using my Original charger + Cable and I notice that it is not really sensitive whenever I use it while plugged in.. Worst is at the middle and gets better as you go out to the edge of the screen. (problem gets amplified if I get into skin contact with anything that has direct contact with the ground)
I suggest trying out a different cable or socket as it seems like your body and the charger gets grounded to earth somewhat.
Try using your Ultra while touching the wall or standing barefoot on cement and see if it gets worse..

Screen sensivity problem !

Hello all and please forgive my poor english
I really love this tablet (thickness, battery, weight, screen) BUT i have a major problem with it : i often need to tap 2 or 3 times on something in order to launch/select it and it ruins my global experience with the tablet :crying:
Do you guys have this problem and is there a way to alter the sensivity of the screen ?
Thanks

Yes, I have the same problem. Some say, it's software issue, and suggest to wait until tab gets updated.

Yeah that's what i expected but wanted just to know if others had the same problem and if there was already a workaround for this
Many people have this problem, including a number of reviewers.
Nevertheless Sony refuses to acknowledge the existence of the issue. When I called them, the guy said "You are the first to report such a problem". (Probably he lied and was advised "from above" to say so...)
The customer is left in the cold!
Some people have a return policy - what if one waits for a software update, the return period expires, the update comes, but it doesn't fix the problem and it turns out to be a hardware problem??
The information politics of Sony and other companies (yes, Google, you too!) is an absolute PILE OF S**T!!
Yup, me too. The annoying thing it is difficult to document. Yesterday my tablet was charging and I turned the screen on using power button - lock screen didn't react at all to my inputs. Tried switching screen on/off a few times but it didn't help. Also tried double-tap to wake with no success. Went to get my camera to document, then of course it started working...
I've written this elsewhere, but this is how I notice the 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 touches, 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, also the android-buttons seem very picky that you have to hit them right on the spot to work.

Damn ! i'm not alone....
One forumer said he thinks that switching OFF Stamina mode helped a little bit...
I don't have my tablet with me, can someone test this ?
"A little bit" help is NOT enough.
The touchscreen MUST work perfectly, whether with Stamina Mode on or off or whether with Mode XY on or off. No discussion.
Sony HAS to fix this.
Already solved in .55 firmware

The same experience with Z1 compact and support. Told them the camera is really broken - they told me there is absolutely nothing wrong with the camera and I'm the first one who got this problem. That was some weeks before, now they officialy added that maybe some devices are defect.
But that´s Sony, they give a **** about u, don't even try to contact the support.
I'm also having this issue, if I'm using the Sony sleve it's impossible to use the touchscreen as it will tip over when I press hard enoug for the screen to actually register it.
No problem here.
Only early days yet. The only prob I've got atm is Dropbox isn't showing up in the Album.
Edit: Fixed the Dropbox problem by using the Dropsync app.
I also seem to get this. The tablet works fine when tilted at an angle but for some reason can be completely unresponsive when it's laid flat. Would this suggest a hardware issue or a software bug?
I also get this, sometimes it's like I just need to press harder (so hard the tablet falls over when using the cover as a stand), but other times it seems that no matter how hard I press or how many fingers I apply it doesn't register a thing for periods at a time.
I'm lead to believe that this is either software or firmware considering the intermittent nature. Are there any custom ROMs out yet that we could flash to eliminate the software aspect?
I have same problem, most noticeable in Chrome, switching tabs fails to register 10% of time. I can only think Sony have a hardware quality control issue with the digitizer as if it was firmware related, surely everyone would be suffering. Strange none of the reviews have picked this up, but I'm going to have to return mine.
No, no, no.
It's most surely a firmware problem!
The electric current threshold for registering a touch is set too high. So if the tablet lies on a non-conducting surface, and especially if it was not touched for a longer time, there will be touch problems. Also touching the tablet with a fingernail will not suffice because nails conduct current worse than skin. Other tablets which have a lower current threshold also accept fingernail touches.
I'm very sure: If you hold the tablet with one hand and touch with the other (and don't accidentally use fingernails), touch will be OK! Right? This is because more current will flow.
The .55 firmware which is out for LTE devices already and will follow for WiFi devices lowers the threshold and thus fixes the problem.
Up to then always take the tablet in your hands when operating it.
Interesting theory, just gave it a go, inclusive, but does seem worse in case. However if Sony aware, why have they not rushed out firmware as otherwise initial user experience is ruined.

POTENTIAL FIX FOUND (ROOTED ONLY)!
Rooted users can try this fix, works for me! Touch seems to work perfectly now, also when tablet not in hands and lying on non-conducting surface!
Edit the file
/system/usr/idc/clearpad.idc
and alter these two lines:
Code:
touch.pressure.scale = 0.0001
(original value: 0.1)
and
Code:
touch.filter.level = 1
(original value: 2)
Don't forget a nandroid before
Please report whether it helped! :good:
P.S.: just for the curious - on the first Tablet Z, the two values are also lower: touch.pressure.scale is 0.0074, and touch.filter.level is also only 1.
Thanks for suggestion but dont wish to root (I use it to watch Sky which wont work if rooted) - seems there is more assistance on this forum to the issue than from Sony. I'll give it another week for a firmware fix before returning it.
elaborate...

My bad, didn't read all the way through, ignore me.
Now after a few days I can say:
With the root fix described above, my tablet works like butter. Simply perfect. :good:
Only instance where I have still problems is when the tablet was lying around for a while and I try to operate the touchscreen without taking it in my hands. Then sometimes (not always) the screen doesn't react, but only for a short time.
The problem seems to be related to static electricity.

[Q] Touch issues even though i have the latest FW?

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.
- Frank
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.

[Q] Rolling screen, please help!

Hi all
Sorry for a newbie question.
I have a Sony Z Ultra which I really like, but recently the screen sometimes just starts rolling for no reason. I cannot read anything, and it often does not stop. I turn the screen off, then on, and it often doesn't show anything but then it does it is still rolling. I have to hard reset, and even then have to do that a few times before it starts up normally. It seems to be happening more frequently. Any ideas on what I can do?
Thanks so much
Craig

It is more like rolling upwards, like an old tv that is not tuned to the channel properly (I am showing my age here because I still remember that)
I cannot take a screenshot because everything on the screen rolls, so cannot access the screenshot function or anything else for that matter.
I have found that when it happens I bend the phone backwards a little and it stops. This makes me think that perhaps the case may be slightly bent from a drop or from having it in my pocket which is somehow causing the problem.
It is not doing it now; I hope it won't return

From what you describe it sounds like your flex cable is causing the issue.
If that's the case, I could be wrong you can take it apart or return it to Sony. I'd just buy a new one. Sounds like a flex cable issue to me
A final development in the story of my phone. The rolling came back, got worse, and then I had times where I would push the power button to light up the screen out of power-saving screen off mode, and nothing would happen. The back-light would light up, but just a blank, black screen...
I sent it to the repair center and the quote came back. It would need a whole new screen.
The cost was going to be pretty high, so I looked online and bought a whole new phone for only 60 cents more than the repair quote!
I just hope my new phone lasts longer than the old one
