Note II Touch Input Lag

[WelshBloke]

Just because polling rate isn't the culprit doesn't mean it isn't latency.

No. but I'm not seeing how this is latency if the device is responding (pretty much) immediately and following your input smoothly.

Short story is thats how Android works, if you don't like it theres plenty of other (well... at least two) OSs that work differently that you can use.

The above isnt meant to brush you off but you aren't going to be able to change that input method and theres no point in sticking with something that you find unacceptable when there are other alternatives.

I dont see what the big deal is. So what if it takes like 10ms to respond to a touch. I can observe what you're complaining about, it just has no impact on my usage.

Guess you only use CRTs, game with wired controllers and use ethernet only.

 

[badb0y]

I think that is just how Android works. I have observed this before but it's something you just have to get used to if you want an Android device. I have had 3 iterations of Android phones over 3 generations and although they have improved a lot of things that "lag" is still there.

Here we go: http://www.youtube.com/watch?feature=player_detailpage&v=E406xXr4Mok#t=125s at 2:05 you can see what is happening and how it's different.

The dude makes a living ripping off mac users. I don't dislike him and he can be hilarious at times but I don't expect him to be unbiased. (and we know Chrome has some issues in Android)

Just checked the "Show touch" in developer options on my Nexus 4, no perceivable lag whatsoever on my koi live wallpaper.

Edit: Besides which, the OP specifically requested,

Please leave the iOS vs Android, denial comments, OMG you're too sensitive comments at the door.

Let's help her/him out instead of preaching to choir.

 

[lopri]

To OP: I am still not getting what you exactly mean by "input latency." Is it related to touch sensitivity at all? Is there a difference between finger v. S-pen?

I couldn't actually listen to enough of him to get an impression of whether he was biased or informed to be honest.

Honestly you don't have to listen to him. Mute it and look at what he does.

@lopri as much as you want to spin it this actually a real thing and a lot of people (specifically those that jump from iOS to Android) feel that "lag" or "stutter." The OP's video does a better demonstration because it's slowed down so you can actually see the difference.

In plain terms the way that iOS tracks your finger 1:1 but Android is like trailing your finger. Not a big deal but it's one of those "what has been seen cannot be unseen" moments.

I had the same experience with my GS3. Input lag when typing which I could not stand. You would think they would have found a way around this without having to root and boot. They haven't, at least in my experience, been able to overcome this simple limitation. Of course I've only owned two Android devices, the other being GS2 and both running default OS's.

 

[lopri]

@badb0y: WTF? How am I spinning anything? The OP specifically asked it not be iOS v. Android thing. If this is such a thread, sure we can talk about it and dig deeper. But the way I read the OP is that her/his Note 2 is experiencing lags that should not occur for how s/he configured it (compared to other Note 2, I suppose)

Perhaps you should make a thread about iOS v. Android, instead of derailing OP's specific query.

Try turning on "Show Touches" via Settings->Developer options->Show Touches . Notice that the white circle does not keep up with your finger; it's at least 2-3 frames behind if you move it faster than a certain velocity. Very noticeable when pulling down the notification bar; doing it fast enough can result in a distance of ~2cm between the bar and your finger.

I'm laughing to myself right now. If you can't see the lag without going out of your way to make it apparent, how is it a problem?

I've noticed no lag on my Note 2.

You can see the same thing on any Windows PC, turn on mouse pointer trails. It's not input lag: it's a feature, working as intended.

i think this is what he means? ..like i said earlier, i think its a hardware issue.

 

[_Rick_]

It's probably a smoothing algorithm, that samples over the last few milliseconds and smooths out some of the measurement error, that the capacitance measuring device has, as well as jitter in finger movement and similar things.
The delay certainly is there, but as long as the reaction of the phone remains predictable, it's not so bad. Also, I haven't noticed any problem while typing.

Testing with the stylus (same problem of the same magnitude) precludes that it's a hardware issue, and instead points to something like an Android setting, or maybe a kernel device class setting. It's not specific to the touch interaction, so the touch hardware is not the culprit. Neither is the processing hardware.
You can probably patch it out yourself, if you take a custom ROM and turn it upside down, to find where this is introduced.

To anyone who who complains about a 10 ms of input lag, I certainly hope you don't use any flat panel display, ever. (10 ms in the input lag of a Dell U2311H, one of the fastest IPS monitors.)

 

[Chocu1a]

I still have no idea what the problem here is? My note 2 is fast and responsive. I can draw without any lag using Sketchbook, my handwriting notes using the s-pen is instantaneous, no lag. There is no perceivaable slowdowns at all. I saw & commented on the thread over at [H], too. Unless the op's note is a dud or lemon, this phone is blazing fast.

OP video: It looks like to me that android requires something like a set distance of swipe before before scrolling to the next homepage which make me think that it is intentional(in the software) to prevent accidental scrolls
Browser video: It looks like android is adding a slowdown animation when stopping the scrolling which is not present in iOS

I can see the exact same effect if scroll up and down fast in a browser on a Windows PC. I don't think it's an Android problem, or a Note 2 problem. It looks to me like it's a silly gimmick feature of iOS to scroll really smoothly and you are trying to make it sound like it's the most important crucial feature in the world.

 

[Raduque]

I'm not assuming anything, I'm suggesting that it exists, and asking why. And I'm expression a feeling that this detracts from my experience of a very high performing, expensive device.

Not true. What is this assertion based on? Apple, Microsoft have significantly lower touch lag without any impact to the perception of smoothness. Try an iPhone 5, its quite a difference, and easily as fluid as the Note 2.

Android has a certain amount of "elasticity" built into the scrolling animation. It's a visual effect that also has a secondary effect of smoothing the animation and allowing it to respond smoother.

I'm sorry that you don't like it. Change the ROM, change the device, or learn to live with it. It's not "lag", "latency" or anything of the sort, it's a design choice.

 

[vi edit]

One problem I commonly have with my Note 2 is if the device is locked and a call comes in the "slide to answer" frequently does not respond to the first 2 or 3 swipes. I've actually missed a couple calls because the stupid thing won't unlock even though I'm frantically trying to slide the bullseye over to the right. Annoying.

As for the OP, the "elasticity" comment is probably the best I can describe. The response is kinda rubber bandish in how it stalls for a split second and then flings forward. I'm used to it now. But if I go back to an iOS device the response seems much more immediate.

If your mouse input is causing a delay then your computer sucks or your mouse sucks. My mouse moves damn near 1:1 with the cursor on screen.

It's not a problem or a gimmick or anything it's just how the different OS' work. To the common Joe they probably won't even notice it but those that do will definitely be annoyed by it.

It's just a matter of moving with your finger vs following your finger.

Grab the scroll bar and drag up and down quickly.

Youll see that the scroll bar is not "glued" to the cursor arrow.

You're right. Input lag is not intended behavior. I hated this on Android and was one of the reasons why I can't stand the OS.

I think its a mix of screen tech and OS.

Input lag is not normal! It should stick to your finger as much as possible. Didn't MS or someone demo this?

Oh yes, ignore every single counter argument where the thing he is experiencing is intended behavior.

That makes sense.

Why?

 

[vi edit]

Why?

I think it's a lot like steering wheel feedback in a car. I absolutely loathe the new "electronic" steering in vehicles because it's removes any tactile feedback from the front wheels.

Most people couldn't care less. It's just a preference in what you are used to. I tolerate how Android works, but I still heavily prefer the immediate snap of IOS.
