Touch sensitivity decreases and latency increases in specific condition! - Asus Zenfone 5Z Questions & Answers

The ZenFone 5Z has a multi-touch issue since its launch that, ignored by the brand, seems to have never even been analysed.
The problem can best be seen, just as I detected it, playing first and third person games that use the two-thumb control scheme.
It turns out that when we slide a finger on the screen, the response is 1.5x slower than with 3 fingers, with three or four fingers it's smooth. When we slide two fingers on the screen, not only does the sensitivity decrease, but the latency increases by 2x each. Causing an effect like using a low DPI mouse playing with a sniper on a shooter.
There's an application on the Play Store called "MultiTouch Tester".
With the application open:
Slide one finger on the screen (preferably slowly for a better view of the effect) and notice it's not that smooth.
Now hold one finger anywhere on the screen, and with another finger, slide slowly as you watch the graphic response to your command stutter.
With three or more fingers it gets better.
Here are some videos that demonstrate the situation:

In the first video, a comparison that demonstrates the ZenFone 5's ironic victory over 5Z:

In the second, a full screen view of how problematic camera control and aiming accuracy become in games:

The third, in fact, is a YouTube channel, where videos are posted that demonstrate the same effect to two-touch controls:

Searching YouTube and ZenTalk isn't hard to find more users having the same problem either. From the reports, it is present in all 5Z, in any version, ever since.
To all readers:
Please perform the tests that was described throughout the text and answer what your experiences were.
To those with knowledge of the bug:
1) Is it a hardware or software problem?
2) What could be causing this?
3) Is there a solution?

I just tested as you described and I do not face the issue. It can be a touch panel issue with your device. I am on the latest Android Q build.

Oh, thanks for testing, itsakjt.
It's hard to see it through the test app if you don't have another device to compare.
But it's very...observable...in games like Identity V or PUBG.
If you start a game, and use two finger, one you will hold on screen to move you character, another you will slighly, slowly slide to move camera. You'll see the effect, it destroys any "flagship experience" you could have playing on this phone.
If you test a game, could you make a video of your test and post here?

Anyone here?

Any fix??
I've been having the same issue since I bought the phone(last year November) and I can't find a custom ROM or kernel that would fix it which makes me feel like it could a hardware issue but Asus wouldn't claim it to be hardware issue rather says the device just has a very sensitive display. I can't play any high end games even though the phone has such good processor. If any fix is found I would be most grateful to that person.

Anders_ASUS, from ZenTalk, has detected the issue and now the team is investigating the causes. Hope for a fix in the next FOTA.

I'm having the EXACT problem!

Desire Screen - Is it the same as the N1

I heard that the incredible has an improved multi touch screen at the hardware level [compared to the N1], and was wondering if the Desire has the same physical screen as the N1?
Sorry I really really did search everywhere, if its been answered before.
Thanks.
Yes the Nexus and Desire share the same screen and with it the same 'problems'. I can understand why some find this a problem, but the I doubt many will actually use 'multitouch'. Dual touch should be enough, which works for pinch n zoom. Other than that, I don't use it. Unless you are an airhockey 'enthusiast'. Of course if I could actually choose between the two, I would obviously go for the better one. The Incredible and forward, all devices will probably have better screens than the N1 and Desire.

djind,
Do you know if there are any Android application that has been designed using multitouch yet besides the games?
For example, is there any webbrowser that users two finger swipe left, two finger swipe right, two finger swipe up, two finger swipe down, three fingers touch, etc to effect different web browsing actions? Or, touch music players that fully utilise single/double/triple finger swipes, three finger touch, etc to perform everything from changing volume, chaging songs, changing playlist, etc without having to look at the screen for buttons while driving?
With a class full of iphone addicted gamers, I can see where full on multi touch is an advantage. Theres just so much game developers can do with the full screen avalible, BUT, we're going to see even more fragmentation on the marketplace now.

No I do not, but there must be a reason for that.
Don't get me wrong, I like multitouch, it adds a lot to devices in general, but let's not forget that we have a mobile phone in our hands, or usually just on hand. Priority number one should be enabling the phone to use single handed the best possible way.
You can't actually use multitouch gestures and not look at the screen, what are we talking about here? If your phone does not have a volume rocker on the side, don't use it as an mp3 player (I must say I like the Creative X-Fi2, but you shouldn't have to wake the screen in order to change volume, bad Creative, bad!)
Multitouch gestures generally use more effort to perform compared to hardware button or a single button. One finger swipe is still number one in my book. You would have to give an exact multi-swipe from top to bottom in order to get the volume settings just right, or click on the volume rocker while your eyes are on the road.
Multitouch, like I said, adds a new dimension to the whole experience, but using 3 fingers on the screen covers most if not more than the whole screen. I don't see any ease of use in that. Yes you can use it for a shortcut, but actually performing a 3 finger action is what I think puts me off. A way to browse would indeed be two finger flick for next and previous page, or just touching the left/right key on the browser screen. It is all about ease of use.
The multitouch gestures are cool, but someitimes or usually unnecessary. Having all options and functions is fine, but I think most of the time anyone uses them is after: "Look what my phone can do."
At the end of the line, it's all about usefulness and necessity.
I don't play games and such on my phone (not a lot anyway), probably why I have these views. But somehow they still kind of make sense to me.
Palm has done a great job on the Pre and Pre Plus. The gesture area is the best implementation of ease of use and productivity I have seen so far, combined with the cards view option. I am definately getting a Pre Plus once they get here. It looks like it just works.
Too bad the HTC takeover is out of the question now. I would have loved to see what the great devs at xda could do with WebOs and their creativity and user feedback.
edit: Holy SHhh this reply is huge.. my apologies for this. I have to do some work for school, probably why I wrote this long reply..
i dont think ive ever encountered an iphone app that requires the use of more than 2 fingers (though it can detect up to 11 i think)
though the issue is that the desire can't even do 2 fingers well enough to go beyond pinching actions, anything like the hundreds of iphone games that require 2 fingers just won't work properly. which isn't much of an issue now as these kind of games dont really exist for android, but it may put devs off creating anything like this in the future.
One thing that I think proper multi-touch helps with is the onscreen keyboard.
Personally I think that typing on the virtual keyboard on the Desire is sh*t compared to the iPhone (which supports proper multi-touch). Perhaps I will have to adjust my typing style, but I just cannot type quickly on the Desire, whereas I can on the iPhone, also with fewer mistakes.
If I had the choice and the Incredible was out here in the UK now, then I would get it, no question (despite it's "looks that only a mother could love", and no hard keys for Home/Search/BackMenu).

N1 & Desire have Clearpad 2000, Incredible has Clearpad 3000.

How so?
Unless you somehow can use more than two fingers to type on a 3.7" screen then there should be no difference.
I agree about the iphone keyboard. It is perhaps because I was used to it, although I made the necessary mistakes, but I think mostly it has to do with the lay-out of the keyboard. It looks somehow as if it has more space between the key's which make it easier to actually hit the key you are focussing on. That's the feeling I get when I compare the Desire in my hands and the iPhone in my thoughts. But typing on the desire is fine.
Still gonna get the Pre Plus with portrait keyboard!

Nope.
yeah typing on the desire is a lot harder for me than the iphone too, tho i don't think this is a multitouch issue.
the iphone keyboard guesses what key your tying to press, so even if you hit the one next to it the one you intended to hit comes up, im not sure if the desire keyboard does this.

I stand corrected!
In reference to the keyboard issue - I've barely used iPhones, but I was typing quickly and error free in 60 sec. On the Desire it seems to register a single touch as more than one touch sometimes, causing a lot of error correction to have to go on, slowing me down as I have to pick the correct word from the list.
Hello everyone!
Just to confirm and prove it with a video, the Desire has the same issue as the N1

Sorry for the link, but I am new and my account is not verified
Desire has a real multitouch, it's just that the Y axes is reversed when you use 2 fingers, this will be corrected in Froyo.

Here it is: http://telephonino.altervista.org/en/google-rilascera-a-breve-android-2-2-“froyo”/
I've read it on others websites.
It's obvious, when you watch videos of this bug or play yourself at AirHockey, you can state that it's not messy/random, just reversed.
In fact it's a software issue so it can be easily corrected but as it may be in the driver which is not accessible for devs, we have to wait for an official update from HTC except if someone can dump N1's driver if it has been corrected with the last update, could someone test multitouch on the N1 as it has the same bug under 2.1 ?

Froyo will not fix multitouch bug.. confirmed by froyo users on Nexus One.
You know I tried that app on the market to test multi touch and I could move 4 fingers/points at once... so I'm confused.

Honest review from a critical nerd (me)

I've has my Galaxy Nexus for a couple of days now, on the Three network in the UK.
I hate how most people in reviews rave about phones when they have just forked out for them, and fail to mention any real negatives - presumably because they refuse to accept that something they've spent £500 on might be less than perfect. When you buy one and it's missing features or isn't quite what you expected, it's very annoying.
Here are my thoughts so far. I consider myself a power-user, and have tested almost everything. Overall, people are right. This is the best phone I've touched. I think once devs start optimising their apps to work properly on ICS it'll be even better. Fingers crossed that Cyanogen will address lots of the annoyances below.
I hope this is useful for someone
The Good:
Feels much more complete and unified.
It's lightening fast.
Most of the best bits of Android have transferred.
Screen looks great.
Face unlock works much better than I thought. Even in low light.
I've only had one crash despite installing a tonne of apps and testing every feature. [EDIT: a few FCs today. Mainly from the pre-installed Google Earth).
Radio seems to work fine on Three UK, unlike the SGS II which has data issues due to fast dormancy. Data speeds are great.
Browser generally much better.
Text input much better, but editing is a little confusing and seems to vary depending on app. [EDIT: This is actually phenomenal. I've always had a hardware keyboard or Swype before so no practice on these keyboards. After only 48 hours, I can literally type without looking. It is very good at correcting mistakes.]
Screen size is great for me, as I use my phones as mini-tablets. Doesn't feel bulky in my pocket at all.
BLUETOOTH STEREO FINALLY DOESN'T DISTORT - I can hear hi-hats again instead of just distortion. There is a bit of constant crackling though.
Screen remains responsive when charging. I have had an issue where it wasn't registering touch properly when charging on my Milestone, Desire and SGSII so this is really nice.
The Bad:
EVEN THOUGH I'M SUPPOSEDLY IN AN UNAFFECTED BAND, IF MY PHONE DROPS TO 2G, AND SOMEONE WALKS NEAR ME MAKING A PHONECALL IT PUTS MY PHONE ON SILENT.
The 'menu' button is unpredictable. For example, in most apps it appears at the bottom with the softkeys. In Market it's up at the top, near the search button. In some apps, it has gone. Seems to vary and is confusing.
You're stuck with the Google search box on you home screen. I hate this.
Now the button has gone, if an app doesn't have a search icon, you've lost the ability to search.
Also means no long press search, so you have to go back to the home screen for voice commands. This also means that regardless of what launcher you use, if you want voice search, you NEED to have the Google search widget on your home screen.
No USB Mass Storage – they've opted for media device profile instead. My Xbox recognises it but can't play any content. It doesn't work with my car stereo. It doesn't work with my TV. My laptop will see it, but I can't see certain hidden folders. This has just removed a huge aspect of flexibility from Android. It's no longer universal, and more like an iPhone now in that respect.
Icons are as ugly in real life as everyone expected.
Blue theme clashes with everything except blue. Blue icons on blue background feels very bland.
There is a huge problem with speech to text, whereby it is very slow, and seems to just write a list of names out of my contacts directory rather than writing what I say! Video here: http://youtu.be/qHVptz2EtMk
No longer accepts certain file formats over Bluetooth.
Camera seems buggy when reviewing photos. It works confusingly.
Gallery is not very intuitive at all.
Browser doesn't display Javascript animations properly.
Dropped a few calls.
Wifi range isn't as good as my other Androids
Front facing camera doesn't aim inwards towards your face. It points straight forward at 90 degrees, but it's positioned on the right of the device, so your face isn't central unless you hold the phone at a bit of an angle facing away from you. [EDIT - this is getting very annoying now. You have to have the phone screen pointing almost away from you to video call]
Bluetooth calls don't seem to work. Caller can't hear what I'm saying. [EDIT - I'm told it works on newer kits. Mine is a Jabra stereo receiver]
Bluetooth music has a constant crackling behind it, but it's barely noticeable in loud music.
All albumart appears in the phone gallery.
Google Talk seems to sign out after a while. It's showing all of my contacts as away even though I know they're online. Signing out and in again fixes this temporarily, but I'm guessing I would miss video calls whilst offline.
Phone has gone to permanent sleep about 3 times in 2 and a half days now. Requires a battery pull to get it back on.
Apps - If you can't live without these, I'd recommend waiting to buy until they're fixed
No menu button is shown on Facebook, so there's no way to set it up to sync contacts or notifications. This means no contact photos for now.
Twitter on the other hand syncs all my contacts, despite me telling it not to.
Doesn't support Swype as yet.
Doesn't support MX Video Player.
iPlayer not available in the Market.
Grooveshark app doesn't work due to lack of flash player. You can use Dood's music streamer for a functional but unattractive alternative.
Thanks for the review and honesty. It would be nice if you kept this updated as either your opinion changes or things are fixed from either Google or app developers.
Is web browser as smooth (scrolling, pinch to zoom) as one on the galaxy s2?
I really beginning to wonder if Verizon is going to put these out there in two weeks without some fixes/improvements in place. I mean, if December 8 is real, these phones have got be in sealed boxes already. People will be returning them faster than they sell them.

It feels a lot smoother than my Galaxy S II did.
I'm about to test the bluetooth quality, as crackling audio was my biggest pet hate from previous Android versions.
Can you resize the search widget? If we are stuck with it maybe something smaller will help minimize that particular drawback.

yes, please test it. whole forum with owners GN but nobody had test this opportunity yet
I hope yopu don't mind but I am going to hijack this thread and also post a quick review from a similar nerd is maybe over critical. Saves starting a new thread.
The Good
ICS is very polished, much more so than any other version of android, it tries to stay consistent through the whole phone where as in previous versions it was one of my main annoyances.
The device looks fantastic.
The speed is very good, I wouldn't say it is any faster than a SGS2 with a custom rom IMO but it is a lot smother in animation etc. so it feels a lot faster.
The screen is very nice, playing videos when the screen is set up to an acceptable brightness are amazing with colours a lot more natural than the SGS2 or the yellow tint of the iphone 4.
Radio is very good also, getting full signal in my house where as before i would only receive 2-3 bars.
Text input is a lot better although i have found it is unable to keep up with my typing, although it is putting the letters down it almost seems like there is a little delay in the animation of them magnifying.
Notification light is back and I am glad, as I missed that feature on my SGS2.
Has everything, NFC, noise cancelling mic, 720p display and ICS. Its pretty much future proof (in terms of the next few years)
Zero shutter lag is a very good feature
Bad Points
The screen although very nice on full or half brightness is not very good on auto brightness. It is so much lower compared to all my other smart phones it is almost unusable I find so I have had to manually set the brightness.
Auto rotate as I have mentioned in another thread is very inconsistent, very fast in some apps nearly non existent in others.
Sound quality is quiet, not poor quality but very quiet. My SGS2 and iPhone 4 over power it when playing videos.
The browser is fast but it is not as fast as my SGS2 running Check Rom Revolution HD. It is deffo faster than the iPhone 4.
The camera is not great, its not bad but the quality feels like it is from a year old device. Quite grainy, not as good as the SGS2 or the iphone 4s unfortunately.
And lastly a few quirks which I am sure will be sorted out with an over the air update, occasional stutter when opening app draw, gallery doesn't seem terribly smooth when going through photos and the auto rotate is just annoying me.
Other than the above I don't want people to read this and think it is doom and gloom because it isn't. This is a very very good device, I am glad I purchased it because it is still the best phone on the market in my opinion.
Every phone has its niggles but that is why this forum is so great, I am looking forward to the community baked roms which always make a device go from very good to just awesome.
To answer some question, you can't resize the search bar. Its not really a widget its sort of like the controls at the bottom, permanently there.
when typing does it type well, what I mean is it off when typing and you keep getting bad letters up, I had that problem with the SGS2 someone mentioned it was a screen problem that it kept jumping
thanks

Nope, can't resize it. It's there permanently. You'd have to install another launcher.

Good lord. That's a lot of negatives. Thanks for the honest review for undecided minds like me. Just two questions. If you use a 3rd party launcher (for example adw) will the google search bar still be present? Secondly, how does the GPS perform in terms of fix time and accuracy? Does barometer really help GPS fix time? Thanks

The GPS fix for me is very fast, easily within a second or so. Much faster than my Desire was, that's for sure.
A lot of those negatives either will be resolved soon by Google or they won't be a problem for the majority of people

Well you have to bare in mind that ICS is a big over haul, so if we were to list all the positives it would be a pretty big list. I am just venting my negatives of the device, but when you compare them to how good the device is they really are small and I would rather have this handset than any other. I forked out for both my SGS2 and the Galaxy Nexus sim free and i am not dissapointed with either. If you are undecided on whether to upgrade you have to look at the fact that this phone does have everything, is a developer phone and has ICS written specifically for it. I would say go for it.
If you use a 3rd party launcher the Google search will not be present, my GPS has been excellent, I have used it for a few car journeys and it is just as good as my SGS2 which was superb.

Yep I know, ICS seems to be the biggest change among the previous Android versions. Together with Google & developers' support, it's why I want to jump ship to the Nexus line. At the moment I'm leaning towards it, just wanna read more reviews. Although the volume adjusting problem that many people are having is a bit of a concern. Hopefully it will be fixed by a software update.

Stock Browser issues

Just wondering if anyone else has the same issues that I get with the stock browser.
It seems quite sluggish when scrolling but the main problem is when zooming in, it is slow to redraw. When zooming out I get a large white screen around the part I was looking at and have to wait a couple of seconds for it to redraw. I have looked at various browser hands on one YouTube and none seem to have this issue.
It also seems to just close itself occasionally with no error message.
Thanks for any input.
I've installed Chrome beta and it offers a lot better browsing experience. It doesnt seem to have the redrawing bug when you zoom in.
Those reviews on the Internet have an updated version of the OS. Most likely this update fixed the issue.
Ya, the browser is terrible slow when it comes to scrolling and pinch to zoom. But I never had a delay of seconds. Definitely something wrong btw with some lower level implementations . Stock ICS browser has the same problems.

How nice for HTC to make sure the review devices were updated hehe.
Maybe I have been spoiled with the browser experience on my Galaxy S2 with a custom rom . Pretty sure back when that was new I had similar issues.
At least some noted developers are already here and working on Roms.
Will give Chrome a try too.
Don't know if this for sure, but i faced non of the phone arena touch issues
i had 3 fingers gestures disabled in the phone settings and hence had full multitouch
if someone can confirm it works better with full multitouch?

Sounds weird. I spend at least 4 hours browsing on my phone everyday (news, forums, deviantart, 500px, etc) and I honestly cannot compare my experience to any other. It's butterly smooth, fast as hell, and most vivid. My only complaint is the battery life, I can't get more than 5 hours of browsing on WiFi...no matter what.
I think you may have a rogue app in the background. Try reflashing your stock ROM without restoring any apps, and see if the problem continues.
Cheers
this video shows exactly how i described the browser, locked 60fps with only the tiling/flash effect when the page snaps, happens in split second, first time i experienced such a smooth stock browser, its much smoother than opera mobile
http://www.youtube.com/watch?gl=US&hl=en&client=mv-google&v=KATvmiBcXvw&nomobile=1
im convinced the issues you guys mention are related to the 3 touch gesture mode in settings, i had this setting disabled
I had lag also and when i got the phone ran the multi touch and would only record 2 fingers max, disabled HTC's 3 finger swipe and now it is very responsive. Ran the test again and now records up to 9 fingers.

hold on a second! first thanks for confirming the browser issues are related to this setting
maybe this is the cause of all problems!
3 finger swipe is actually used to send the image/mirror to the HDMI output, maybe its causing the other issues?
I should thank you for bring up disabling the 3 finger swipe which reminded me of the the touch sensor test i ran when i got the phone.
Thanks.

[Q] floating/hovering touch phenomenon

Hi,
does anyone else experience the phenomenon on his M8 device, which is pretty much similar to the Xperia Floating Touch feature (can not post a link to a description of this feature sry, just search google with "xperia floating touch" for more information about that).
About 1 out of 10 "touches" is already detected while actually hovering (1-2mm) and not touching the screen. Most of the time this is no issue, while playing flappy bird e.g. this is pretty annoying though ;P.
Is this a bug or a feature which I'm not aware of(searched the internet and forums, but didn't find anything about that) and how can I turn this off?
I am using the Android Revolution HD 8 system at the moment.
Thank you for your help!
It's just the sensitivity of the screen, combined with just how charged your skin is. I get it a few times weekly,just a few,, my gf,who also gets lots of random static jolts from lifts,car doors,etc, gets it constantly,and can barely use it. ( which is perfectly fine by me!) I find a slight tongue touch to the tip sorts it for me.

[Q] A bit disappointed of the Tab S (stuttering/lag).is there any trick to fix them?

Hi guys I just bought my Tab S 10.5 (T800) a couple of days ago, however I'm finding some annoyances, that are giving me a headache when using it and are making me think, to return it
1) When i'm scrolling a website or flipboard in my usual way/speed the text/images appears to jump a tinny bit like if it's stuttering, instead of smooth transitions.
2) When the keyboard "launches" it doesn't matter if I turn off the animations or put them at .5 or 1x, when on the browser I'm trying to type something on a search bar there is a white tail before and after the keyboard launch, this tail makes the content on the bottom of the keyboard to appears like a flash. However this doesn't happen when trying to type an url, This is better noticed on a dark background for example go to this site mary-black.net (or whatever site which has an embedded search and uses a dark background) and launch the keyboard trying to type something on the search bar and then hide the keyboard.
The keyboard "white tail" doesn't happen on my sero 7 pro running an AOSP rom, however it has some stuttering while browsing, but I though it was because some kind of underpower, because my S4 running a touchwiz rom it doesn't stutter at all it's like butter on every single scrolling page/app/etc but it has also that "white tail" sometimes but it's so quick and is not my main browsing device, so I was trying to replace my main tablet an ipad 2 (7.1.2) which it browse like a champ exactly as my S4 and is way better than this Tab S
yeah I have tried a lot of browsers, maxthon, chrome, firefox,opera, dolphin, boat, and the less worst is the stock one
Oh and also it seems to not hold webpages on ram, because when I go to a link and then go back, instead of showing me the content right away, it shows a blank page and suddenly the content, however this a problem because if i was on a search or something it brings me to the top of the page again, and also typing something on a search is laggy, the letter don't go with the keystroke.
BTW: I don't use touchwiz launcher, I'm using nova/apex.
I have enabled also Force GPU Rendering and Turn off/on hardware overlays. nothing seems to fix it.
Also have found that the performance is not consistent at all, sometimes the apps load very fast, browse very fast and it's a pleasure, but sometimes it lags, yeah not like a minute or so, but the overall experience using it, is not something I was expecting, I was expecting at least the same behavior of my S4 and S2 and way better than my old ipad 2, and unfortunately none of those are met
Any ideas ?
Thanks.
You need to do a video to prove it, that's how it goes around here.
1) same here. I is only slight stuttering and only when scrolling intensively, but it is noticeable. I tried all the browsers, but best in this regard is stock browser, followed by chrome browser (which I currently use). Some of the other browsers have even more severe problems regarding scrolling and also impose certain lag registering scroll gesture.
2) I am using TouchPal and not seeing any keyboard "white tail".
3) Webpage caching: yes, it does not keep pages in RAM and requires a reload. Particularly annoying when on a mobile connection. I've not yet come across any browser that does a proper RAM caching of pages. Also the OS seems to grab the RAM. E.g., when you have multiple tabs open and switch between Apps it does reload all the tabs. Ridiculous. At 3GB the Tab S should have plenty of RAM.
Overall the Tab S hardware is capable enough to provide a smooth user experience even with the above issues. But still I am hoping for some fix.
Probably some tweak of the memory management could help? Also investigation of background load. Seemingly there are to many services that do indexing, report back to Google or Samsung, check updates etc. Probably also the Mali-T628 GPU has some premature driver implementation? Or maybe the Samsung color enhancement for AMOLED is the culprit?

Cool, I have a feeling that you tough I was trolling , well here they are, this one shows the ugly white tale, and it also happens using google keyboard, and any keyboard.
http://youtu.be/kfUbyTVjF6I
As you can see that "white tale" is not present when trying to type an url.
Here is one with the stutter very visible.
http://youtu.be/f9DHYdlc4d0
Here is one showing the reloading on going back. which btw it also shows how with only one finger touching the screen it sometimes act as 2 (pinch to zoom) this little problem is very rare but it's not the first time has happen, and you can see the lag on the keyboard before launching also, there is that "white" then the keyboard.

Here is one comparing the scrolling on the same content first the ipad 2 and then the tab S
http://youtu.be/0TYgm43eBxc
The ipad also has a bit stuttering, but not as much as the S, which IMO this should not be happening, the S has way more power/ram than the old ipad 2
I hope yours is not acting like this, could you please provide a video if yours is working at it supposed to be..

Yeah the more you start using the tablet, the more stuttering it appears, and also when trying to open the recent apps, sometimes there is also a lot of lag until everything appear. The problem with this is they are not predictable.
I tried that keyboard and is doing me exactly the same (white tale), I think this is because instead of launching the keyboard and the placeholder at the same time, they are launched a different time, and I have just confirmed this enabling Layout boundaries under developer options. :/
My 8.4 works exactly as yours. That's how it is.
white tale seems to be some re-rendering issue of the app, not the keyboard.
One might check with Cyanogenmod whether it persists there too. Pretty sure it is some SW issue, HW should be plenty capable.

I bet it's software issues, launching the placeholder for the keyboard before and after the keyboard. But to be honest I don't want to install Cyanogen or aosp to this tablet, because that will break sidesync, multi window, s planner and s finder. if I would need to flash those roms to be able to enjoy the hardware then I would go with a boring but trusty ipad or wait to see what is announced on september at the IFA.
- Similar hardware used on phones with 1080p screen to drive 1600p screen, which is almost twice as many pixels to render. The GPU is working extra hard but should still cope.
- TouchWiz makes this much worse and through past discussions, this is mostly the cause of the lags and stutters. If you use some other popular launcher, lags and stutters would almost be non-existent.
- iOS on iPads and iPhones are smooth because Apple only need to focus on optimising on their own hardware. Android on the other hand has to work on so many combinations of hardware out there, it's much more difficult to make things buttery smooth like iOS.
I see these issues as well on my 8.4, but not enough to get bothered by it, but would welcome any improvement through OTAs.
Replacing the launcher has zero effect on anything except launching an app!
There might be some touchwiz related code behind the scenes, but to replace that you need a revised ROM.

I'm using Nova or Apex, yeah those don't have lag on the major of transitions, but sometimes they stutter just a bit, yeah not a breaking deal. But the stuttering while browsing/reading and the keyboard issue is making me have headaches, and that will not be solved using another launcher.
I understand that point regarding iOS, but trust me, my S4 is running on a touchwiz rom and it doesn't act like this tab S, geez even my old S2 never acted like this.
Regarding three Samsung bloatware, there are replacements for each of them, if you really need that. I personally think, most of it is just premature and unnecessary. Multi window for example. What do you do with that? I just have GMD gesture control with some user defined gesture to switch between the last apps.

I run excel spreadsheets while browsing for making quotes, compare values and stuff like that, need to compare spreadsheets with word documents, to give you an idea I use 3 monitors for my desktop.
So actually multiwindow is a very usefull "gadget" for me, and that's what got my attention, the 3gb of ram I though well this will handle my workload with out a problem, 10.5" screen good space for multi window, and well the exynos ? I would prefer a snapdragon version, but I don't need LTE on my tablet as always I can theter from my S4, and none local store have one with snapdragon in case I need to return it or something.
And yeah GMD Gestures is a must for a tablet.
I now own two of these devices, a 10.5 and an 8.4. I use Nova Launcher. Even running stock OTA I have never experienced any scrolling lag or stutter using the stock browser. My only complaints were some keyboard lag which I believe disabling DVFS improved and using a firewall hack to speed up embedded video steaming. Other than that and the typical pageload lag JavaScript causes I have had zero lag or stutter issues with either tablet.
As setup currently both of these tabs are completely smooth.

Wait.... So yours are not showing that white tail or the keyboard placeholder like mine is doing it here http://youtu.be/kfUbyTVjF6I ?

OK I see your problem. The fade animation is working properly when you select the address bar but not when you select a text box on the actual website. I think this is just the website re rendering as the keyboard closes since you were interacting with it. You only really notice it because the background of your website is dark.
I believe this is a stock browser thing as it does not do this using Dolphin.

No. Mine does a nice fade and drop down animation. What yours is doing should not be happening.

Yeah that kinda of fade is what I'm not getting, it only does that fade when i'm typing on the address bar, but when i'm typing on something inside a webpage that trail appears. In what build are you ? Mine is NFB, hope anybody else can confirm if they have it or not and what mods are running.
I did factory reset but didn't solve it.
EDIT: Well this happen on white pages also, "covering" what is on screen. I did that on a dark background because is more apparent. If I enable layout bounds on developer options it shows that the placeholder is triggering before the actual keyboard. Tomorrow i will make a video with the layouts enabled.
And mine is doing it with every browser i have tested.

I changed my original post. I think you missed it. Yes I am getting same thing in stock browser. This does not occur using Dolphin. Not a Tab S issue. A stock browser issue. The dark background of your website makes it more noticeable.
Update. Does it in Chrome browser too. If that bothers you try Dolphin browser.
I got the same white tail issue also in chrome browser.
Dolphin doesn't do that, gives a bit better re-rendering. But Dolphin mini also struggles. Weird.
Both are slightly more sluggish in scrolling, that's most important, so I sorted them out.
Also that nonsens gesture implementation (requires to press a button first) did not win me.
There is one thing the stock browser by far does the best of any browser I have tried. Play embedded video clips. Dolphin? You may as well not bother. Expect 10+ second load times. Using a little firewall hack I'm getting almost instant video loads in stock with no buffering lag.
The little white flash when closing the keyboard is a non issue for me, especially when using a website with a white background. Don't even notice it.
maybe try to debloat the ROM and then go into developer options to change the animations to .5 or disable them entire(I disable them in all android devices I own)
Well I don't know what happen, I did some factory reset like 3 in a row, then the first thing I did was, go straight to update chrome to 36.0.1985.131 and now it's working at it should. Yeah with some occasional stutter, mostly when launching an app. But not like was doing it before. The white tale is still there but not as heavy like it was before.
