Asus TF700 screen flickers occasionally - Asus Transformer TF700

I have an Asus TF700 android tablet running Jelly Bean 4.1.1.
When I play games, use apps or just use the tablet even in the play store, the screen will occasionally flicker (i.e. a small part of the screen in the game/app will slightly move and "flicker").
I'm using the "stretch to fill screen" setting. I tried the other setting to no avail.
I took the tablet to the lab and was told that this is a software related issue.
Any help/ideas would be appreciated.
Thank you in advance,
Gali.

I have this when I'm reading PDFs in Repligo or Mantano -- doesn't matter in which program. Might be a driver issue. Haven't noticed it in the games we play on the 700, but then I do not game all that much and my 4-year-old son will probably totally miss out on the glitch.

I am not sure if this is related, but have you guys tried this: Setting -> ASUS customized Setting -> uncheck Enable smart backlight adjuster?

Hmmm
Haven't even thought about that.
Does this do away with the screen bugs?

I don't know, I am just throwing out suggestions. On the tf700, there is this feature called "Smart dimmer", which acts like a second auto-brightness , changing the screen brightness based on the content of the page being display and causes the screen to flicker a lot. Can't hurt to give it a try.

Thanks for the suggestion but I already tried that before I took the tablet to the lab and it didn't help.

Well, anything automatic causes bugs. That's a given. So it could indeed be the light adjusters.
Also, are you running in performance or balanced mode whilst playing those games? Try changing it to the other, some games have problems with performance mode.
Another option is a factory reset.

Thanks for the suggestions. Right now it's running on balanced mode.
I did a factory reset and it's better than before but it still happens from time to time.

Hello. Try to enable "Settings"-"Developer options"-"Disable HW overlays".

With all due respect, no. I think that would do more harm than good. I'd rather have battery left. Reference, for example: http://rootzwiki.com/topic/28977-disable-hardware-overlays/ -- from which I will quote directly:
"Without a hardware overlay every application that is displaying things on the screen will share video memory and will have to constantly check for collision and clipping to render a proper image, this can cost a lot of processing power. With a hardware overlay each application gets its own portion of video memory, getting rid of the need to check for collision and clipping. Basically, using hardware overlays can reduce CPU usage by quite a bit, so I would leave it enabled."
and
"Disable it and the latency period for applications and the OS (any OS, not just Android) itself to render things will go way way up because it has to check to make sure it's not screwing with memory that is supposed to be dedicated to another task than its own. Hardware overlay ensures everyone has their own partition of memory so they don't have to do those checks and so latency to render things on the screen decreases dramatically."
From that, your suggestion doesn't seem like a good idea to me. But that's just me.

I've tried all your ideas before -- I have noticed it on every ROM I've tried so far, although it's the least noticeable on stock, and then CleanROM. It was prominent on BlackBean, but that was an early version (although I believe it remains one of the less mature ROM -- correct me if I'm wrong).

You're right in suggesting to disable it, and that's one of the first things I do when on a stock(-based) ROM. Therefore, unlikely to be the issue here.
Thanks for thinking along, everybody! Maybe it is just a driver thingy, or an API?

This is a well-known JellyBean-specific issue. So far, there is nothing that can be done to fix it (unless the latest OTA update addresses it)...

It is definitely fixed my problem with flickering in ScummVM (part of the screen was slightly moving). Can't see any negative effect till now. I think i'll stay with it as current solution.

Well here's my two cents to this: I've found that my screen mostly flickers when I'm playing music through my headphones in particular through Spotify. I've rechecked a couple of times and definitely noticed no flicker over a reasonable period while my tablet is silent and spotify is off.

Ive noticed when i dont use my tablet i dont get the flicker OR the black line at all!!!
/sarcasm
Yeah.... the things we put up with......

I thought I was the only one with flickering game problems but I see a few people have it too lol well that puts me at ease. But any fix for this?

It's a nvidia driver issue so unless they update the graphics drivers it's unlikely you will see a fix. Some have it worse than others it would seem. I rarely see any lines or flashes. Make sure you turn smart dimmer off as well in the ASUS Customised settings.

I mainly have problems when reading PDF:s using RepliGo Reader. Turning off forced GPU rendering helps a little.
Thwapped on my Asus TF700T with courage

I went ahaed and turned off the smart dimmer on the asus settings and noticed an increase of black lines and flickering all over apps, its not just when i play wild blood hmm strange ill try to turn it back on and see if it changes anything...

lovey,
Is "Force GPU rendering" selected down in: settings/Developer options/Force GPU rendering/ selected?
This might help some with any game that's compatible with the setting.

Does your "pointer location" follows "touch location" ?

TF700T .30 firmware JB, wipe, cold start. otherwise works ok, but:
development options => enable pointer location (shown in blue traces) and touch location (shown as white glowing plate).
You can see whatever you do on the screen, the touch location always follows your finger.
However, if you touch down on the screen with one finger and move around for a while, you can see that the pointer location trace fails to catch up with the touch location --- it can go as bad as a few seconds delay. I have zero such delay, even after touching down a finger and moving like crazy for a minute, on my 3yr-old nexus one phone w/ JB (admittedly much smaller screen).
Do you guys have this problem? Is it a red flag calling for return??
Thanks.
I'd guess this is just the debug option itself that creates the lag by painting an ever-growing location trace. Do you see any negative effect in real use of apps (with the option off)?

Not that I can notice, so I guess it is fine. I don't see such delay on the old phone with the traces enabled though.
I do feel the system is laggy : chrome or browser freezes from time to time. This is latest firmware , wipe, cold start already ....

Unfortunately, that's normal. It gets a little better by installing a custom ROM, but software can only try to work around hardware issues (the internal eMMC has very bad random write performance), not fix them.
The only time I really notice it is if I'm using Sketchbook Pro, but I guess that may be a result of the application or something... It can be hard to draw with it sometimes, since I have to draw slower than I'd like at times.

Rotation Broken

For some reason my rotation has stopped working and i can't seem to fix it. So far I have:
Restored to stock .23
Cold booted 3 times
Factory reset on stock twice
Auto rotate enabled
Used ultimate rotation control from store and that works
Checked sensors and those seem to be functioning
Any help is appreciated.

You did pretty much everything that we could do. However, I have an idea, how about download this third party "Screen Orientation Control by eflow inc." app, once done open up notification and set it to portrait mode, then set it to landscape mode, then finally set it to off (auto) and see if it's working, if it stills not working, there's not much we can do except to return the device for repair/exchange.

Damn, I was hopeful, but it still won't rotate... It is weird too because at some point I was able to rotate, so I cant see it being a hardware issue, but I guess I will need to have ASUS repair/exchange.
Thank you for the suggestion though

[Nook HD+] Touchscreen sensitivity experimentation (updated GUI app on 07/13)

Thanks to some testing by @alal690 based on my instructions in the post on how to play with touchscreen sensitivity we have some suggested reduced sensitivity values.
I spent entire day figuring how to do more things in android apps, and here's my next terrible UI attempt: NookTouchscreenSensitivityAdjuster-4.apk (backup link).
It's recommended that you run it with 07/11 cm10.1 release, but it will work with older releases too, just all settings (all but touch sensitivity on 07/06) would reset on screen off.
This minimalistic tool would allow you to change various touchscreen parameters in GUI, so not need to play with adb.
Right now this tool just lets you to play with values, the new values persist until the screen turns off (and the touchscreen resets restoring to default values).
The "save" button only saves the sensitivity and focus settings at this time, and the values persists across reboots (important to grant it root access the first time you run it!), everything else is not saved anywhere (since I am not sure there's any value in that and only included the other settings so you can experiment with them and perhaps get back to me with your awesome finds).
save button only works with 07/06 release, in previous releases save button does not persist anything.
the "reset" button resets values to the "old" values in the touchscreen, meaning pre-sensitivity change (so to 0x11, instead of the new 0x16).
Old post:
Anyway, here's a test zip that you can flash to try the new value. I encourage everybody to try it both if you do and do not feel like you have a touchscreen sensitivity issue.
If there are no downsides (so far I see none on my end), we might make this one to be a standard new default.
touchscreen-test.zip - this is for Nook HD+ (noop on the Nook HD). (Note, this is now included into 6/30 build for ovation)
Do not flash into stock, it'll break it.
I know the raw TS settings is a bit intimidating, so I plan to make an app for that, though that's a bit more effort than what I have time for ATM, so we'll make do with just this topical treatment.
will this work with carbonrom also? i like to switch between them.
What about those of us who felt it wasn't sensitive enough? Is there some sort of weird effect where its so over-sensitive that it feels less sensitive?

Try it and tell me what you find out.
Feel free to play with other register values as per that other post referenced if you can. No two devices are totally the same. So we'll need a significant amount of testing by all interested parties to come to some middle groumd
Either that, or an app where people would be able to setup volume, touchscreen and other settings for themselves, but we'd still need to have sensible defaults.

i tried it on both. What a difference already. especially on stock browser. sometimes i wanted to smash the thing lol. you are one hell of a dev. scrolling takes a bit more work but clicking links is so much better now. sometimes i would click a link four or 5 times lol

Basically the problem is: there are multiple complaints about people having too sensitive/too insensitive touchscreens. I don't think I am seeing anything like that, but there is more than one report so perhaps different people have different tolerances and different hardware has it's quirks.
The goal here is to arrive at a different set of defaults that would improve the situation for people that feel there is a problem and at the same time don't make situation worse for everybody else who feels current settings are ok.

mine personally was very insensitive. when i'm on slickdeals and i know you are also or bleacher report clicking on links such as hot deals and my subscriptions would take multiple tries. i didn't notice much system wide but mostly on the internet clicking smaller links. whatever he did with this zip made mine personally much much better.

Aha... then I guess I *did* know about the problem. I noticed it most when reading books. After a few minutes, the page turning touches on the lower right margin would seem to stop. I finally just gave up even trying to use them, and substituted a swiping movement. Anyway, with this zip installed, the sensitivity doesn't seem to be any worse, and might well be better. It hasn't been very long, but I'll keep an eye open for differences.
PS: Just read some of the other people's posts, and see that they were complaining of difficulty in clicking links in web pages. I had certainly noticed that, but hadn't even thought of the possibility of fixing it, so had just ignored it. With this new zip, it does seem like web link sensitivity is much improved.

mine is much improved. whatever adjustments were made I feel like mine could go even a little more in that direction. I'm at like 85% now lol
Thanks, alal690! I think he deserves to get some "Thanks", too, but he doesn't have any posts! And thanks to verygreen for providing the tools for alal690 to tweak with, of course!
I have noticed more mistypes on the keyboard verygreen if you are still needing input but the positives outweigh that in my book. it really is much better on websites. please thank the other dev that worked on this also alal690.
Big improvement for me, thanks I suspect the issue with pressing ui elements was caused by jitter and phantom touches that may have been caused by oversensitivity even though it seems somewhat counterintuitive... Selecting text was the big issue for me and it's now vastly improved. As has my accuracy on they keyboard - normally I'd have had to retype half of a post this length
BTW, it woul be great if people with some sort of a protective film over the touchscreen will give this a try to make sure it's also ok for them (I know those screen protectors are really popular amongst some people).
I've spent the last week trying to fix this, but it looks like it could be a problem with a driver or the actual hardware itself. If you go to Dev tools, then Pointer Location, you can see the reported values for touch pressure and size. When holding down my finger anywhere on the top 2/3 of my screen, the xy and size values jitter like crazy. If I touch the bottom 1/3 of my screen, there is no jittering and the size value is constant.
I think people that are complaining about low sensitivity are mistaken. I think the touch screen response is actually too sensitive, thus causing the jitter and making it hard to click on hyperlinks.
Reducing the touch sensitivity scale and increasing the touch size in the IDC file has helped a lot, but the jitter is still a problem that I hope someone can figure out how to fix.

I agree with phammichael that the real issue here would be jittering, but my symptom is different.
This is what I found so far.
- Pinch out to zoom in something (in gallery or web browser) and hold the 2 fingers on the screen.
- If my fingers are on the right side of the screen surface (portrait mode), the screen jitters. You can see the touch values changing fast and continuously by tiny values.
- If my fingers are on the left side of the screen surface, the screen won't jitter and stay calm.
Am I the only one experiencing this issue?
BTW, this is before I applied verygreen's touch screen patch. I will report back after applying it.

The jittery right hand side of the screen in portrait mode is the problem - I have this on my HD+ (which was new) and my Dad has it on his (which was new) as does my friend (again a new unit)
There have also been lots of others reporting the same thing on here.
Put the HD+ into landscape mode and the issue disappears.
I've just applied verygreen's 'fix' zip and I have to say that touch response is loads better - clicking links etc works far more reliably (but right hand side of the screen in portrait mode jitters still exist)
Great work as usual verygreen

[Q] Touchscreen lateral movements delay (sensitvity Issue ?)

Hello, I have an issue with the touchscreen of my nvidia shield tablet.
I bought the tablet only one week ago and I'm on the Stock lollipop version 5.0.1 (2.2), but I had the same issue with the KitKat version.
When I hold my finger on the screen and I change direction, the shield take a long time (about 1 second) before validate this change of direction.
This issue make all my games unplayable in touch mode. (If I use a controller, this problem doesn't exist)
I wanted to post a video to show the problem but I can't because I'm a new user. (I can pm the link if necesserary)
On this video I activated, in the developer mode, the trace of the movement to see that the lines moves very late after my finger. (I'm doing the same test with LG G Pad to compare and see that it respond perfectly)
In the Real Racing Game: I move my finger with very little fast movements and the wheels doesn't move at all.
I tried the calibration tool in lollipop but the problem persists.
I tried also a Custom Rom ([ROM][4.4.2][wx_na_do] AOSP for Nvidia Shield Tablet LTE US)
My questions:
- Does every Nvidia Tablet Shield have this problem or is it only mine?
- Is there a way to configure the pressure and move sensitivity (from the config file /system/usr/idc/touch.idc)
I would like to know if someone has the same issue to know if I have to send back my tablet in warranty.
Thanks in advance for your time.
I've had this issue, but only while charging. More noticeably while charging using 3rd party chargers, though the nvidia charger does have some "lag" as well.

Thanks you for your answer.
I have always this problem, I never tried when the tablet is charging.
In fact the touchscreen is relatively responsive when I touch and release quickly.
The problem is when I let the finger on the touchscreen and I change the direction slowly with small moves.
Hello,
I re-up this post because I really need your help.
I sent back my tablet to the seller for my touchscreen issue.
But they don't undertsand and tell that there is no problem with the touchscreen.
They compared to another Nvidia shield and told me that the response is the same than mine.
I can't believe that all the Nvidia shield has the same response because for me all the games are unplayable.
So I would like to know if someone has the same feeling (delay) about the touchscreen when you slide and change laterally the direction with your finger to play games like racing or platform games.
Thanks in advance
Sorry if I open this again.
I've been going crazy with this issue too and have been looking around for a fix, too.
I tried applying different configurations to my /system/usr/idc/touch.idc file, without any noticeable differences.
The only setting that works for sure is 'touch.size.calibration': the possible values are "none | geometric | diameter | area | default". Whatever I set besides 'none' will make the touchscreen work like a touch pad (you scroll around and there's a little cursor moving, you tap and it taps on the cursor's location).
I'm not sure which setting (if any) can calibrate the touchscreen for small movements. The documentation is a little unclear (I only found this: https://source.android.com/devices/input/touch-devices.html ).
Does anyone know more about this configuration file? I believe it's a common issue for all the shield tablets, it would be great if we were able to fix this.
Please note that root is required to edit that file, of course. Plus, the /system partition needs to be writable (mount -o rw,remount /system).
Same issue on new k1
Same issue on K1
I purchased an new K1 today and am experiencing the same issue. After enabling "show touches" in developer options it is very clear that the display periodically becomes unresponsive. I have also tried to re-calibrate the display with the Sensor Calibration Utility with no change. This happens while NOT connected to a power supply. So, I'm not sure what else to try.
What have others done about this issue? Do you return the device to the reseller? Because as it is, I can't play most games and find a typical browsing experience annoying.
Thanks in advance for any advice.
After trying everything, including full wipe, different Rom etc, I have returned it to the reseller. I got another one and and am very happy with it. Turning screen off and back on gets the responsiveness back for a while. Good luck with swapping it for new one, reseller I dealt with made no issue of it.As I have restored tablet to factory settings,I have just shown a video of a tablet going all crazy to a guy at the counter, and he gave me a new one.

Xperia XZ firmware 41.2.A.7.8 – keyboard issues!

Hi guys!
I've updated to 41.2.A.7.8 but the one bug I hate the most on this device is still here on Android 7.1.1 – some of the keypresses are recognized as a straight swipe line when typing fast and thus Swiftkey keeps assuming wrong words. This happened as well on all past firmware versions I’ve tried.
You can easily check this behaviour by entering *#*#SERVICE#*#* on your dialer, choose Service Tests, then Touch, then Free Drawing test, and then pretending you're typing (both thumbs) at high speed.
This is even more evident when you are using Stamina mode, and more so in the more aggressive Stamina options, which leads me to believe it’s processor dependent. Xperia X also had this very same bug but was corrected with firmware updates so… come on, Sony! Stop screwing things up!

You can easily check this behaviour by entering *#*#SERVICE#*#* on your dialer, choose Service Tests, then Touch, then Free Drawing test, and then pretending you're typing (both thumbs) at high speed.
This is even more evident when you are using Stamina mode, and more so in the more aggressive Stamina options, which leads me to believe it’s processor dependent. Xperia X also had this very same bug but was corrected with firmware updates so… come on, Sony! Stop screwing things up!

It's an issue with Sony moving to swiftkey as stock. Sony's own keyboard worked much better on older versions, you can still use it on Nougat, but it's a bit slower in touch response. This is why I use Gboard. If I could disable predictive engine in swiftkey, I wouldn't mind using it that much, it's annoying and I hate that blank bar above the keys, uses up the screen space. I also don't use gesture typing in any form, so the old stock xperia keyboard was always my favorite.
Ditch swiftkey, try something else and see if it's better. The issues people describe with keyboards in 7.0+ are non-existant for me. Or at least disable the gesture typing in swiftkey settings. But still, the predictive engine makes it laggy and glitchy, even though it is by far the best predictive and gesture keyboard out there.
The free drawing test isn't really a good measurement here, it's for drawing lines, not tapping. Use tap test and you'll see no matter how fast you tap, the digitizer registers taps. When you tap on the drawing screen and manage to tap a single pixel without touching the next one, it will stay black, it looks like it didn't register a tap.
The keyboard, and the entire UI in general, being laggy and slower in touch response while using Stamina actually makes sense and is completely normal. It lowers the screen refresh rate, the touch responsiveness and the framerate of the rendered content.

No it is not. This is an issue with the way touch screen inputs are processed, regardless of the keyboard you are using.

It isn’t better. Every other keyboard behaves exactly the same when the wrong inputs are interpreted.

These issues existed for Xperia XZ on 6.0 as well.

That is even worse because when you disable gesture swiping, right to left (wrong) swipes are interpreted as deleting the previous word.

No, really, free drawing test is exactly what we’re after here.

When these touch screen issues were solved for Xperia X, you got perfect typing behavior even when Stamina mode was on.

I don't see the keyboard issues when using gboard or atock xperia keyboard, although the stock one is a bit slower in response, so I don't use it.
The way it behaves under Stamina seems normal to me because it's how my ex z3 and z5 behaved and it makes sense. The performance of the phone is reduced, ofcourse it will be less responsive and laggy.
Not until we recieved the swiftkey, I havent seen this issue.
The way they "fixed" the tapping responsivness on the X was by not using so restrictive and conservative stamina profile, it didn't reduce the digitizer responsivness as much. It's a battery saving mode, after all, you can't have both with equal efficiency.
I'm sure they could do the same with the xz, but it would mean affecting battery life as well well.
Free drawing test makes no sense if you are testing tapping speed...
Or are people complaining about swipe input? If that's the case, than drawing test would be useful. For normal tapping on the keyboard, I see no issues.

Looks like you haven't even actually tried the Drawing Test yourself...
Some of the taps are recognized as a straight swipe line when typing fast and so this problem will always be present regardless of the keyboard software you're using.
Can anyone check this is still present on 41.2.A.7.35?

I have tried the drawing test when I read the post, also the tapping test, otherwise I wouldn't even engage in the conversation.
The lines in the drawing test do not appear on my unit, when I tap quickly on the drawing test it doesn't draw these huge lines.
Does this happen in normal mode as well or only in stamina? Cause I didn't try in stamina.
I'm on Customized CE 41.2.A.7.8, and the device is rev.1

You have to type even faster
This happens in normal mode as well as in stamina mode, but it becomes much more frequent in Stamina mode - in fact it becomes more noticeable the more aggressive the Stamina mode chosen.

I was tapping as fast as I could, faster than I would normally while typing a message.
But I guess I'm doing something wrong or I'm just a slowass typer so I don't see the issue.
Good luck eith yours, I hope you solve the issue or Sony fixes it.
Maybe start off by doing a full software reflash to a latest version released today? See if it helps maybe...
Cheers

Just asked in a different thread whether 41.2.A.7.35 corrects this issue

Unfortunately, 41.2.A.7.35 still shows this bug.
