[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.

[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.

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

Multitouch and flash player.. imposible or not find yet?.

We know before update, x10 not have multitouch .., and they have multittouch after update from se official., does that mean x8 had posibble too get multitouch if we can update the touch sofware?., if we see how x10 get the multitouch after update, maybe that mean multitouch not about hardware but about sofware., we need some one to solve this.. some one who can give us surprise

About flash player., the situation it like this , we can instal its but cant use its.., adobe say its only for armv7 and hight., and not for armv6.., but i think x8 its not support any flash player.. i had try instal any kind flash player apk to my x8., but no one realy can work and play swf file.,that mean flash player must include from the original rom.

Multitouch/dualtouch: Not possible, most of us has the Synaptics digitizer and their specs on the Clearpad 1000 says it is Singletouch Read more here: http://www.synaptics.com/sites/default/files/190-000015-01-Rev-D-CP1K.pdf
Now, there is another digitizer called Cypress, but i doubt it will have support for multitouch either.
Flash: Won´t happen. Adobe flash does not support Armv6 cpus, which our phones are equipped with.
Please stop spamming the forums with threads like this! Flash and multi/dual touch wont happen no matter how many threads like these you create! Trust the devs here, they know what they talk about!

Yeah I like the people too, whose not looking around, and writes that synaptics T1021A is only single tuch. I mean ok, it IS single touch, but with a little logic, it will be possible to make a pretty good emulated multitouch, like what if we force the sensor to refresh the position of second and first touches alternately with 0,5-1ms delay, and force it to merge the recieved datas in one datastream (e.g.: to send the information to the cpu in 1-2ms breakdowns [logicly the double time that each position's data arrives], when the two positions has merged)? It will be a little laggy, but it won't be annoying.
To be more simple: It's like you touching for example the bottom left corner and bottom right corner alternately with really high speed. In this case the screen won't shake in a game, because it's not like you slide your finger left and right (with common software it percieves sliding, try it)
Damn I can't program in C...
Wonder if it will work...

Yeah that makes sense. I guess they developed something like our x8gesture.
@skyboyextreme, look at this clip
Look carefully at 0:14 and 0:30, when the user zooms out. It seems to be not a real dual-touch zoom-out to me. It looks like a gesture
And don't expect too much about MT/DT capabilities. You really want that, come and get a better phone
/edit: also, look at this
At first, 0:01, it seems to zoom at correct center (between two fingers), then at 0:02, the zoom center is at the black area near top of the screen. It isn't at the correct zoom center (which was supposed to be between two fingers).
/edit #2: another one, this seems good,
This is map app, seems a good zoom, but look, it always zoom at the screen center...

Uhm, I wouldn't say the screen is lagging or so. It's the digitizer that is quite dumb, as it can barely hold track of two points.

Well giving you this for answer the digitizer is just a bit slow after testing seeing its same indifferent on our roms, this will not affect anything in general terms. You should be happy for what you paid for really.

The better one would be Defy, if you saw the video how fast it read and responded to his fingers. X6 seemed to have not so good digitizer, would be considered the worst out of all of those.

Touch Screen Problem may not only on Z1

So far I've seen lots and lots of people complaining about the touchscreen malfunctioning on the Z1, saying that this is a hardware problem and thinking of buying a Note 3 and G2... But then, you maybe have never knew, that almost all the other phones out there have the same problem as we do.

As for the Nexus 5, I have not seen any videos that suggest that it has the touchscreen problem,
But this : https://www.youtube.com/watch?v=5XEvM2nGRmk
I think that all these manufacturers such as Samsung, LG, Sony, etc... Use the same Sypnatics touch digitizer.
Please don't criticise my post too badly if it's stupid, I'm just trying to help everyone
EDIT : For Xperia Z1 it's worse maybe because of the Aluminum frame...

Hey guys I have a tip for ya'll who have the touchscreen problem, go to Settings > Launguage and Input > Scroll down the pointer speed and make it to the slowest. It has lessened the touchscreen bug from happening for my device. Hope this helps

Guys, can it perhaps in at least some instances be bugs in the sketch software and not faulty hardware?

Maybe it's an issue for all S800 devices

Hey guys I have a tip for ya'll who have the touchscreen problem, go to Settings > Launguage and Input > Scroll down the pointer speed and make it to the slowest. It has lessened the touchscreen bug from happening for my device. Hope this helps

I did that and not much improvement. I still have problem to open my phone with patterns so I can't said about any improvement but still hope for an solution with the update, hope for gift christmas. I already wrote a letter to Santa Claus.

Gg nice post, ao people get some prespective. Z1 is an awsome device, damnit 6 hours brilliant screen time on a 5inch Fhd, i've seen battery report from g2 averege is 4.5 hours like ours, and can get to 7 with power savings. Z1 rocks

Screen problem is hardware problem due to aluminum frame. Screen can't be fixed by update... If you wanna fix screen problem... sell your phone.

Any proof for that? I might fully believe that since xperia SP also has the same problem both have aluminum built.
HTC one also is made of aluminum. My Final solution really is to sell the phone but in the even that there can be some possible fixes to reduce or completely remove the problem then it's great. Maybe hardware remedies or software. For now I'll just wait and see what 4.3 will bring.

Not really sure about that, on mine there is no such thing influenced by the aluminum frame, I did 1000 of test and videos. Sometime it come, sometime it vanish, sometime I can't open the lock screen via pattern if I leave the phone on the table.
