[FIXED (repaired!)] Touchscreen/keyboard 'bounce' (update 26-10-10)

I've tried a lot of android builds whilst the development has been going on and found that Bangster's 1.4 coupled with Michy's R11 was the best for me with regard to screen sensitivity and keyboard accuracy.
I recently had a dabble with m-deejay's next-gen builds Desire HD/Z etc (which are excellent by the way, credit to him), and found that I was getting a lot of screen bounce, missed button presses and a very frustating keyboard experience (Hastarin R7.1). Pressing and holding the delete key for example would result in keypresses bouncing all over the place, sometimes several keys removed from the delete key. I tried a plain Froyo Sense build and found the same thing, although not quite as bad.
So, I decided to try the bare kernel from Michyprima's R11 (AXI, Desire, OC) on my current Froyo Desire build just to see if it was down to the kernal 100%. Instant bounce removal... keyboard is accurate and now when I press & hold on the home screen, I don't get the screen wobbling from side to side as the software thinks that I'm moving my finger around rapidly.
To recap; it seems like I was getting more bounce with Hastarin's R7.1 than any other, but certainly Michy's R11 (Desire based) is making my phone usable again. It really was bad before.
More messing required methinks... I may re-load the Desire Z build on to my SD card and try R11 to see what it's like. One thing I remember is whilst trying m-deejay's Desire HD 3.1 (which had an Evo kernel IIRC), keyboard bounce was almost non-existant. It wasn't until I changed to D-HD 3.3 that the keyboard became a pain to use (Hastarin R7.1).
Hastarin if you read this, please note this is by no means a dig, I have the greatest respect for all the guys posting builds here, these are just my obvservations.
As with all things Android/HD2 related, YMMV. Your thoughts are welcome.
---------------------------------------------------------------------
---------------------------------------------------------------------
Edit: I've taken a couple of quick videos of m-deejay's brand new 3.4 Desire HD build showing this phenomenon (kernal is huanyu's #21). Replacing the zImage with Michy's R11 virtually eliminates it.
Video 1 - homescreen
Video 2 - keyboard
Could this be Windows ROM related? Might flash another WinMo ROM to see if it's any different.
Edit 2 Sent my HD2 back to HTC today, hopefully for TS replacement... see relevant post here.
Edit 3 Received my HD2 back from HTC's repair department. Problem fixed. No more bouncing Relevant post here.

No-one else with similar experiences?

Me too!
previously was using M-deejay's froyo sense 2.2 and the keyboard was a great improvement from my old stock HD2 Windows keyboard, which was oversensitive and jumps alot, making typing a hassle. I did not have any problems with the froyo sense 2.2 keyboard, it was accurate and sufficiently responsive, and even have my essential chinese input.
However, after the 2.4 version was released, i updated it, and noted that the browser's bookmark crashes. So i though, why not give EVO Sense 1.6 a try?
Btw, i did not realise any problems with the 2.4 keyboard, so it's probably as good as the 2.2 version.
Then i ran EVO sense 1.6, and i feel that the keyboard is different. Firstly it's the additional arrow buttons below, which is useful, and more like the original HD2's keyboard. Then it also has chinese input.
BUT i experience alot of the "bouncing" problems, if not more than my original HD2 windows rom. tried calibrating a few times, and deleting the calibration, but it doesn't help.
i want to emphasize again i am very grateful to all the developers like M-deejay, Hastarin, for developing all these builds that are effectively working. this is likewise, just my observation.

Anyone else? I can't believe it's just us two!

Videos added to 1st post.

I tried to replicate your problem (m-deejay's Desire HD 3.4) but I coulnd't. I also thinkg that the keyboarad its not as accurate as some of the builds but its not that bad as yours.

I'm sorry to say but the lag with the keyboard kinda looks funny
My keyboard isn't very accurate too. Sometimes it just takes the wrong key. I mean when I press the backslash it takes "m" or something although i was pressing backslash. This was on Hastarin 4.1.
But it really seems to be kernel related. With the r11 my keyboard is okay.
I don't think is caused by the WM ROM, but which one do you use?

have the same prob!

yep...and I get phantom touches also.

Thanks for your reply. However, my screen isn't defective as I don't have this problem in Windows and using a different kernel fixes it.

that's great my friend

Well.. i have the same thing in hastarins latest kernel

I dont have this on DesireZ out the box.

I have MDeejay's latest Desire HD build and have this problem, how do I fix it? If I need to replace the Kernel how do I do it? What side effects will it have?
Thanks in advance

keyboard bounce also experienced by me when i am trying to type fast, using hastrin r7.1 as well, maybe is caused by the touchscreen delay?

have you tried keyboard calibration?
in the setting menu ..
it ask you to type that ..lazy brown fox jumps..
it helps me alot.. well some of it i guess
and also try the schrub bartome build. the keyboard is perfect-iphone like. im using this build for day use

I experience the same issue with the new kernel releases. But with hastarin #3 the touchscreen works normally.

HD2 Multi Touch?

Sorry that I keep asking noob questions today! I was wondering does the HD2 have multi touch in Android? Dont really care about Windows mobile. For stuff like pinch to zoom in browser or games like Nova with need multi touch?
Thanks.

Pinch to zoom on browser, maps ect. Yes.. as far as the game Idk..

edit: never mind my previous post. forgot we were talking about android.
afaik multitouch on hd2 with android works pretty good everywhere. cant remember any games in particular, but it works everywhere else that it should work

runningdap said:
well, the answer is both yes and no...
hd2's captive screen allows multitouch, but because winmo is a really old OS they didn't really updated it so that it supports multitouch 100%.
On the other hand, if you run android on hd2, you can see multitouch working pretty good though.

Great thanks to both of you that is great to hear! If someone wants to tell me it works in games too I would be super happy. Not just Nova that was just the first multi touch game that came to mind.

multitouch works with newton cradle at least.

HD2 Does not support True multi touch. As you can see when you touch both finger on screen then when both finger on the same line your multi touch will freeze. USe market multitouch visulisation 2 to test it and you will know what i mean.

i think it assumes two fingers but more it doesn't work. does desire hd solve this isue?

Yes, the DHD is able to recognize up to 4 fingers and thus 4 different moves.
That's because of the built in clearpad 3000. It even supports up to ten fingers. But this depends on the driver.

[Q] HD2 Multitouch Issues

hi i have been have a very big problem with the multitouch on the HD2 running in android NAND the best way of showing this is using the app multitouch visualizer 2 which is free on the market its shows that when the touching two points on the screen when two axis become near each other from the vertical axis or the horizontal it will move both points that are being touched
is anyone working on this problem and if so are you working on more than 2 point multitouch for the HD2 android

You should post this in the right section Android Q&A

The multi touch is a known issue. There are debates on whether or not the HD2 supports more than two fingers also, but that is irrelevant right now, as two finger multi touch doesn't even work properly. However we also don't know if it is the HD2 that simply can't handle the two finger touch or is it the drivers.
Now iunno if anyone is actually even going to bother with the problem as the only times the problem is an annoyance, is during gaming, but that is, gaming with a joystick and etc. So I don't think devs are actually going to bother with a problem they don't even know whether its the device or software.

ah...
but since it only support two touch i think mine got a lil bit problem with 2 touch,
like it will get trouble when i am trying to put 2nd touch... like playing gt game, which im breaking it also react my steering that makes me unable to play it...
so it is cant be fix then?
thank for the information then

The hd2 can only support 2 touches, there is no problem with axis inversion , although when the two points are close to each other they lock and that is a hardware problem

No, can't be fixed. When the touch touches are near the same axis, they will both show touches on the same axis. Pretty sure it's a hardware problem. This is one of the big points I always tell people when they're trying to decide between HD2 and a native android phone, along with the fact the HD2 screen is only 56,000 colors compared to 4million a native device has.

well if it is a hardware problem can some one give me a link to a source that shows this

I'm not about to dig up old threads about the touchscreen driver development or irc logs... any of the devs that have worked on drivers for the touchscreen have said this. I remember seeing cotulla discussing it in irc sometime in the last few months. Touchscreen is not going to get any better than it is right now... there has been a lot of work on it over the last year and a half.

i resume this thread to notice that isn't an android issue... it happend on windows mobile also.. and is irritating..

The Hd2 is single-touch and pinch-to-zoom.
It was never intended to have multitouch or android.

well... let this multitouch be for pinch to zoom only but this issue is disturbing while normal tapping on the keyboard.... You tap next letter of your word and You don't release the previous letter so this "next" letter won't be recieved. The touch runs between my fingers, look :

It is not single touch, it dual touch not true multitouch axis inversion is happening in the video as they are putting the fingers to code to the edge of the screen so its messing up.

Is the keyboard multi-touch? Many keyboards aren't and can only receive a single input at a time so even if you type really quickly, you need to make sure you left one finger completely off the screen before typing the next. I can type pretty fast using the HTC_IME that comes with multi-touch. I mean, you can't hit "shift+a" to get a capital "A" but you can hit a key before letting go of another key and the keyboard will still pick up the correct keystrokes most of the time.

M..N said:

Dual touch mode allows a two sensor system to track the absolute location of two simultaneous events provided that they are located in different regions of the screen.
What you mean is Dual Control or Gesture Input aka pinch-to-zoom.

When I was using MDJ_FroYo_Revolution_v._2.1_NAND, i think, Multitouch was doing well. There were no such thing like multitouch problem, even while crossing the fingers. Now I'm using BOYPPC-SHIFTPDA GINGER 2.3.3_V10 and I have problem with multitouch. I'm 100% sure that I was using some ROM with well working multitouch. Maybe someone should check it?
Sorry for poor English...
Edit: I was not MDJ_FroYo_Revolution_v._2.1_NAND. When i figure out, I will make a video for a prove.

Umm I starting to think that i was dreaming... -.-'

Honestly i have no problems with multitouch either using Gingerbread .
There s a couple other things that are a lil quirky but nothing that would make it unusable

Something new!

Well i am messing around with my X8. I made some thing that holds my X8 and i Put down my X8 on it and it gone Landscape mode then i was testing with 2 fingers and i saw 2 touches ( 2 fingers) then i was moving them around like crazy then i saw a Blue , Red And a GREEN one just poped out of nothing and 3rd touch was thare it just flashed a green touch! So i think meybe its not at all clearpad 2000. Or maybe its just a Multitouch visible test app bug? Or is it andrej's module?

i hope to see that in your srom...its going to be the perfect rom if its in landscape..(but not in our mdpi x8)...

No this has nothing to do with my rom. Its in the matter or a firmwere limitation or just a bug. Who knows.

I wasn't able to take a screenshot becouse i was flashing rom's like crazy my X8 got overheated so i installed a normal 2.2 until it cooled down. With andrej's module.

well can you mabe get a video up of that demonstration? I spent like 3minutes hard playing on that little screen and then ****ing dropped it.

Basic Information About HTC HD2

I am going to buy HTC HD2 or HTC Desire HD.
1)From what I know hd2 was made to work with Windows Mobile but supports Android, I wanted to know if the HD2 will run Android smoothly without problems & bugs? Android Market works?
2)The HD2's touch is smooth while running Android? or it has delays?
3) How the Desire HD is different from the HD2? I know the camera is better in desire hd and also the RAM is a bit higher, but what else
4)HD2 works perfectly with Android 2.3 Gingerbread?
5)The phone memory in the HD2 is lower than the Desire HD, wanted to know if it's making a big difference.
6)Desire HD run games/Apps faster than HD2?
That's all for now, thanks for helper

1)HD2 runs android smoothly imho... android 4.0 may have a few problems but thats like every other device
2)im running sense 3.5 which is gingerbread and the touch screen is very responsive no delay
3)dont know anything about the desire but i know that the roms for desire get ported to hd2 so we get there roms anyway
4)as i said earlier gingerbread sense 3.5 is great (using the ENERGY rom)
5) i dont thik the less memory makes a difference i have installed a fair few apps and still have room to spare
6)app/game speed differs between devices some may be faster on hd2 than desire you never know... i find the apps are quite fast
hope this helps

Thanks MkBy for the fast response, here are some more things I would Like to know
1)What you suggest to buy?
2)Which one is cheaper?
3)I might buy one of them from someone (not new from shop), what should I check to make sure the phone is working well and without problems?

I haven't used the DHD too much so I can't say which is better but 0my HD2 on CM7 appeared to keep up in performance in terms of scrolling, web browsing, opening apps etc. (i.e. not benchmarks) with my friend's DHD on CM7, and I would guess the HD2 is cheaper but the HD2 is absolutely terrible for playing HD games or games involving multitouch. In order for HD games to run smoothly you have to sacrifice either speed or graphics, and the HD2's screen only supports 2 points which is a massive let down for me. As much as I love the HD2, if it were up to me and both were around the same price I would go for the DHD, even if it is a slight bit more expensive

Yes, unfortunately It does that very poorly as well, I can't describe it but sometimes it appears to lock the two points together if they are on the same line if you know what I mean, it's quite difficult to describe.

Let's compare the Touch screen to SE Xperia's touch screen, I know that in Xperia you can work with 2 fingers and even more, HD2 can work with 2 fingers like Xperia does? I mean same quality of touch

1 Finger flawless
2 Fingers decent
3+ Fingers doesn't work
NONE OF THAT WAS SUPPOSED TO BE INNUENDO

As I said before, I might buy one of them from someone (not new from shop), what should I check to make sure the phone is working well and without problems?

I have an HD2 and am currently running the Energy ROM with sense 3.5 and Gingerbread. The screen is extremely responsive and over all the phone works great. I would recommend getting the HD2. It is one of the best phone out there as far as specs go and it isn't that expensive anymore.

If you want to buy a second-hand HD2, I would like to suggest you to check:
1. 3G data connection (refer to This)
2. Button response
3. Camera flashlight
4. Record video for 5 mins
5. earphone jack and some MP3
6. blue tooth file transfer
7. speaker
8. GPS in some navigation apps
9. Wifi of course
10.Ninja fruit for multi-touch test
Better bring a TF card with files or pics you want to test.
Since my HD2 has data connection freeze issue, I suggest you to buy a whole new handset like ONE X (if you like htc), with warranty. All these unsolved problems on HD2 are driving me crazy.

I'm running hd2 with ics tytung v1.5 with little to no known problems other than music app fc'ing. Their is a touch issue, namely screen lag, but I only notice it when playing games at a fast pace. Hd2's seem to regarded as highly adaptable as well. Not sure about dhd.

Hi dooshbag45, I am thinking of changing my gingerbread rom to ICS. My current rom keeps rebooting when I am using headphone to listen to music. If i use loudspeaker it does not reboot. I have even had to think twice buying a beats audio headphone because of this problem. Does the ICS rom that you're using only fc or rebooting also? Is it only when you're using the default music app or also with third party app? Mine even reboots when i am using winamp.

hd2 pros
Many OS available (android, wp7, Ubuntu, etc)
Great screen (for devices age)
EASILY nodded
Cons
Touchscreen issues - using more than one finger recognition, failing digitizer (design flaw)
Data drop (happens to some, a simple disconnect/reconnect solves)
1 rear 5mp cam
Specs are showing their age but still hang with the best of em!!!
I've had a hands on with a friends DHD so the below is based on a QUICK hands on
DHD pros
Native android
Slight advantage on HD2 (hardware specs)
Cons
Smaller screen
You want android ... You're stuck with it!

Incorrect. The Desire HD has a screen of 4.3", which is as large as the HD2.

Hi
I've used both. And both are great devices too. The only drawback for both of em are lack of front cam. But IMHO go for a newer model. Like sensation and EVO 3d. You may get it cheaper also.
But the final decision be yours.
