Defective touchscreen?

Does anyoe else's tab do this
When I scroll in a webpage or app, and I stop scrolling but still have my finger pressed on the screen, the screen starts to shake a little until I move my finger again, is it just my tab or is it a common thing?

the only thing i can suggest is that you are slightly moving your finger, its sensitive so might look like its shaking?

Mine does that too. I wouldn't be too worried about it since it only happens in the web browser for me.

its not defective, its cause your holding your finger on it, especially in a web browser if your zoomed in a page and scroll it might happen.
its just your finger moving a tad bit that the tab senses. Also it might be catching two touch responses from your finger, not the tabs fault. Its the way you use it really.
Dont worry. The tabs touch response is pretty sensitive, which is VERY good thing trust me. Its better to be responsive then crappy on a touch tablet.

Sorry, but yes, it is a problem
I'll respectfully disagree. I have the same issue in my galaxy tab, and I've tried several others, this behavior is found in just a few.
I've made a video and a drawing test to illustrate it. I've put them in a page in a domain that I own.
(XDA still doesn't allo me to paste a link, but the address is fgfaria.com )
I've tried an app called touchscreen booster, which appeared to be appropriate from its description, but didn't notice any difference.
But there is a very intriguing point. It doesn't look like it's a hardware problem. I have installed touch test app, and with that the touch is perfect, no shaking. Also, specifically in youtube app, when scrolling the list of videos, it doesn't happen.
I need to find out why it happens pretty much everywhere, but not on youtube app and touch test apps.
Just to make it even more complex: as you'll see in the picture in the url above, towards to the right edge of the screen the problem is much lighter or doesn't happen.
If someone can help, that would be hugely appreciated!
Thanks,
Fabio

I'm getting this problem too. I get TERRIBLE shakiness when i hold finger input especially in google maps.
I highly doubt it's a hardware issue because this only started happening to me ever since i installed the italian gingerbread rom.
This this GB rom giving anyone else the same issue?

Same problem here
I am also having the same problem, installed an application called "Touchscreen Booster" but no avail.
Strange thing is that the problem seems to not happen on Youtube application.
I also have GB 2.3.3, in my case, the overcome room 2.0.0

One possible solution
Did you guys check the url I've sent? (fgfaria.com)?
Is your problem just like mine? In my case, I had the problem since Froyo 2.2, and still have it (the same way, no change) after an update to 2.2.1.
My GT is not rooted, and I'm waiting for gingerbread to be made available through Kies in Brazil to proceed with the update.
Another interesting thing is that most touch test apps behave normally (no shakiness).
Possible good news: I've found an app in the Market called "ILITEK Touch Utility".
Unfortunately I couldn't use it in my GT as it appears to require the device to be rooted. But it has several features from calibration to screen software reset. Hopefully this may help, specially as it seems to be a software issue.
Let me know if this works for you.
Regards,
Fabio

mine does EXACTLY the same thing as per your website.
the app does not seem to fix anything...
sigh...
at least good to know someone else is experiencing the same problem.

The problem is app specific
Hi all,
In addition to touch test apps and youtube app, there are some other apps that don't present the problem. One specific interesting case is the one of the HelloListView tutorial presented in Android Developers website.
I've followed the tutorial, and created this illustrative app that just creates a list and allows you to scroll up and down. This specific app doesn't present the problem we've been discussing. I've made it available for download as apk file in the end of that same testing page (fgfaria.com)
That application being so simple and not presenting the problem, and the other apps that also don't present it, makes me think that the problem may appear when some specific library gets included in an app. Possibly something related to hardware acceleration, for example (just guessing, no specific reasons to believe that).
If only we could isolate the cause of the problem, we could notify Google and/or Samsung and influence a new patch release.
This is as far as I have gone so far. Ideas, reactions?
Regards,
Fabio

Or the libraries being used in this tutorial include some kind of filter not used in problematic apps...

I posted about the same problem here:
http://forum.xda-developers.com/showthread.php?t=1096698
I've included pics from my tests. Notice how before I installed the custom rom, the lines were perfectly smooth. This definitely has something to do with the software. We need to have one of the rom devs look at this and find out what might be the cause.

hi grukko, thanks for your comment!
To me, the most intriguing part is that the behavior happens in some apps, and not in other. I have done a very similar test, which I've published in the address http://fgfaria.com
As you see in the thread, the problem doesn't happen in youtube app, and screen touch test apps and in the list tutorial app I've created following instructions in Android Developers website.
Can you check if your problem is the same checking if youtube doesn't "shake"?
Thanks!
Fabio

Your test results look similar to mine. I just tried youtube and it does not shake.

New discovery:
It may be a hardware problem (at least in my case). A friend, in another forum noticed that the jittering only happens in screens with a light background, specially white.
This can be quickly tested, by opening a web page that has a white and a black part. Zooming in the white part (so that all background you see is white) and keeping the finger still, the screen starts shaking. If you move to the black part, zoom and keep you finger still, no shake at all.

Fabio

Anyone? There is a solution for Galaxy S (forum.xda-developers.com/showthread.php?t=844216&page=3#). There must be a solution for Galaxy Tab 7 too...

Touch screen issues
Count me as another member of the shaky touch screen club! Anyone found a resolution yet?

No luck yet. Official upgrade to Gingerbread is not yet available in Brazil. I'm waiting for this upgrade to check if things get better, but I'm not so optmistic, as I've seen reports from many people to whom the problem actually started after the upgrade. Does anyone know if the problem has already been officially reported to Samsung?

Nope. Not mine, the tab working flawlessly

i have the same annoying issue on my GT P1000 with gingerbread 2.3.3 Kernel: 2.6.35.7
i also have the vibration on Youtube app and any black background slightly.

App display problem

I've noticed a few apps seem to really display awkwardly with CM7 on the Nook. They run in what looks like a little tiny window on the top of the screen. The Engadget app is one such example.
Is there a fix or workaround for this?

I did search, but with the 45+ threads that came up when I searched for "app problem" I think I missed the other one.
Thank you for the reply fix though.
A lot of these things could be handled by a simple sticky that says "common problems and the solutions" right up top! LOL

UK System Update Avaiable???

Just get info about system update to version 2.30.405.1
my current version is 2.21.405.7 (android version 2.3.3)
Any one knows what is this update for?
Will I lose root if I update?

Yes you will lose root if you take the OTA. The biggest change that was made between 2.12.405.7 and 2.30.405.1 is that they have fixed all of the temp root exploits. So not only will you lose root, but you will not be able to re-root until a new root exploit is found.

Thank you for quick response.
OMG! It is good I haven't updated!

Looks good to me. Picasa albums add in working. Screen text a better size. Don't know what full list of changes is?

It's already been done. If you're looking for a ROM in future, the Android Development section of the forum is your friend.

Scrub that, Picasa add in stops working. As useless as it ever was.
Pretty fed up with HTC, they are nowhere near the Company they used to be. Flaky software, useless support, the farce of HTCSENSE.
Horrible.

After reading a few threads about this update, all I ever see is people querying and *****ing about losing their S-OFF. Is there an actual change list available so I see what exactly has been done?

I haven't seen anything. Have you checked the HTC Support site? That is where such information would originate from if it is available.

Surely you cant update if your S-OFF anyway...atleast I cant!

text prediction(suggestion) in portrait mode not working
Hi guys, I have successfully updated to this version.
However the most frustrated thing is when I am typing text in portrait mode, no matter what app (web browser, calendar, message, map, or 3rd party app, etc) I am typing in, the word prediction (suggestion) does not work anymore (or it does, but I could not see all the possible suggestions as I used to if I misspell something, then it just automatically picked one suggestion to replace my word)!! Only when I change to landscape mode they start to appear.
This never happened before this update, and also, before, when I typed on the text box, the keyboard would appear as well as the cursor positioning where my text will display. So I could still see part of the original screen of the app. But now, the text box basically expands a lot so I could not see anything else on my screen apart from the white, ugly, big text box which takes more than half of my screen and the keyboard, nothing else!!
I am wondering if anyone else who updated to this version has the same issue. This is bad, bad, and bad!!
Cheers!!

Ok, I just rebooted the phone twice and everything goes back to normal. I am sure I had rebooted the phone more than once before, but they did not work until just 5 mins ago...

Screen "always on" battery life...

Has anyone tried subj with sideloaded app keeping screen on all the time. (Like https://play.google.com/store/apps/details?id=com.nbondarchuk.android.keepscn ) ?
Would be interesting also to compare mostly black and mostly white watchfaces.

This is something that I really would like so I will try to get this to work on my Gear. I'll report back in a few days.
Thank you for sharing.

I have tried three different versions of these types of apps and none of them worked.
They either wouldn't install at all, or if they did they would immediately close saying "XYZ app has closed unfortunately.
If anybody gets one working correctly, please post the results

Did you make sure to move them over to /system/app?

Its a wishful thinking but Id love to see a MotoX style face for the watch. (Dynamic Notifications App mimics this).
The clockface would always be on and the notifications would only light up those portions of the screen and youd just touch and see what you have waiting.

Live messages window bug

Hi there,
Facing a strange (minor) bug in my SM-N9600 (Note 9/Brazilian/LATAM unlocked version).
The window in the GIF creator/live message become too small.. I really don´t know why and can´t figure how to resize (tried with/without S-Pen, up, down, to the sizes etc).
App works perfectly, but only in this small window.
Tried to stop the app and uninstall updates, no luck =(
Any ideas what is goning on there?
Thanks =)

Someone posted this during the first week of the note 9 being sold. No one replied. Hopefully you'll get an answer.

I had the same issue.
I think the window of the app scales with you dpi. If you decrease the dpi the window should become larger - this was the solution for me.

I am the one who posted that issue on the first week, unforunately no one knew what caused that issue and I had to flash a new firmware and never faced it again eversince
