Hi,
I read about the Google Nexus One having a bug with multitouch. It tracks the finger position wrong.
It seems to be a hardware error.
Does this affect the Desire too? (N1 and Desire are close in hardware)
Source:
http://androidandme.com/2010/03/news/is-multitouch-broken-on-the-nexus-one/
Because Desire in not in sale, nobody knows.
N1 and Desire have the same screen.
For me : Both of them have this bug.
Doesnt the N1 and the desire use same capasitive screen to the hd2 as well?
The screen of the HD2 is bigger (4.3"). The Desire has 3.7"
But those 3 devices could have the same model and manufacturer.
I'm not too worried after reading this post by Cyanogen:
Cyanogen's Solution
If this will get it to work pretty much like the droid, I'm fine with it.

Sorry yes.. Aware of that... (hd2 owner) Mean produced in the same way.. I see the nexus one has the same cross hatches as the hd2.

i hope it is not the same with the desire....
Desire has the identical "Pinch to Zoom" touchscreen... :-(

This doesnt look good.. (i cant post links)
It is hard to see because of the blurry and spotlight reflections, but yeah the line jumps from one finger to the other. damn.

Why is there always something wrong when a phone seems to be nice
I guess we are just going to see when we get our hands on the device.. No point picking holes in it before we even have it. Im sure i can live with this if the n1 owners can.
PLenty of vids out now that show multitouch in-use, such as the pinching on homescreen and using web browser etc. with no problems. I don't think this will actually effect usability. Also, Engadget ran an article using a different multitouch "measuring" software and it had no problems...wouldn't get all upset about this
Agree,I currently own a N1 and this doesn't affect the pinch to zoom at all. It works flawlessly.
its not a big deal!
The issue appears to be a hardware issue, .. but i think there is away to solve it using a software fix, ... for example instead of the OS takes the data as it is from the touch screen that provides it (which appears to be flawed), another layer should exist, that can process the data from the touch screen and fix that issue and then pass it on.
I am not sure how this is can be done, or what is the effect of it on the over all performance, but I dont think it will be a problem with the Desire hardware specs.
Even with this issue, i dont believe it is a big deal, ... why do you need multi-touch? IMO to zoom in, zoom out (impress your friends and family), which works perfectly. other than that I hardly find any useful applications for it, ... ok maybe some games need this functionality to work properly, but i think i can live with not having games that require multi touch.

Typing is one thing that comes to mind
I am not trying to sound like a fanboy, but the multi-touch keyboard on the *cough*iphone*cough* is awesome. I have owned numerous HTC phones and the difference between say the MyTouch 3G and the iphone keyboard is like night and day.
Now, if there is a keyboard in the android market that is comparable then I will take back my previous statement. I haven't tried Swype, but have heard it is really good.

This feature is not effected by the hardware "bug" of the touch screen, .. if you used both ur hands (2 fingers) at the same time to type and clicked "pressed the screen" on two different letters without moving them than you're completely safe
My point was that the type of multi-touch (mutli touch gestures or call it whatever ...) that is effected by the bug (IMHO) is negligible to most users
and that is exactly why am getting the Desire XP

Thanks for clearing that up

Watch from 5:40 till the end. Pinch-to-zoom is definitely there and is HELLA smooth too
So the new Telus Desire has swapped out the AMOLED screen with an SLCD, but what about the touchscreen component? I would love to hear that the Clearpad2000 has been swapped out as well! I currently own a Nexus One and the poor multitouch is driving me nuts.
It's the same, I'm guessing you mean it only senses duo touch still

That sucks. Not only can it only track two touches only, but if you happen to cross the same axis while it's tracking two fingers it will start acting up. It means that multitouch keyboard are pretty much useless.
Anyone keen to play with the Kernel driver for the touchscreen on the desire, to come up with a patch that keeps axis inversion/sticking to a bare minimum? This is the only think keeping me from getting a desire, as I don't want to be held back by hardware. Playing multi-touch Pong and Air Hockey with my friends at school is something I want to be able to do, not to mention the almost console quality games like NOVA. A fix (kind-of) was made for the Acer Liquid By a guy playing with the kernal drivers. All of my developing focus is going into learning Java right now (Gotta start somewhere, right? ) and I do not have a device to test on, so if someone could have a go with the source from the Acer thread or create something themselves from/for the kernel at developer.htc.com would be more than greatful, because I'm not exactly keen on the Desire hd's form facter and buttons, despite the performance. Sucks that all the Desire phones have a big flaw. (Desire - Multitouch. Z - hinge. HD - Size could be a problem, buttons too flush and delicate battery, sim, and SD covers.)
Thanks in advance for your time, and, hopefully, hard work.
Would be very cool, It's practically impossible to play games like modern combat, or any other games where your fingers cross, because of the axis swapping. A fix that, almost, prevents that would be awesome.

Yeh, that very a big problem...

I know it's impossible to truly fix it, but you can get close. personally, I don't care for having more than two finger gestures, I just want perfectly stable multitouch. If someone could create a driver that assigns an id to the first and second touch, and tries to, as accurately as possible, track which registered touch is which, even when the movement exceeds the refresh rate of the screen/sensor, and reads 2 individual touches when they are close/the axises are close. I've been reading up on how the synaptics ClearPad 2000 works, and it reports 2 coordinates for each touch, an x and a y. Shouldn't be too hard for it to not get very confused, right? I'd say, this is a year overdue. But the Desire is still one of the greatest phones ever made (if not THE). This issue still stands between me and it, even though it can barely be noticed in everyday use.
Korntoff, trust me when I say I'm not trying to be rude, although it may come across that way (the internet isn't good at the subtle and nuanced art of conversation) but don't you think it's the height of arrogance to believe you're the first person to have even considered this? It's the 14th of February. The HTC Desire will have been available for a whole year in just two days and you're asking this as if it hadn't dawned on all of these people for almost a year.

Wow...such a simple solution...why have none of us thought of it!!? C'mon man.
so this will never be fixed?
IIRC, this is a hardware issue rather than a software issue. So I don't think it's possible.
i am already regretting buying the htc desire... i am getting it tomorrow.... i didn't know there was that multitouch issue until yesterday... i always thought the htc devices wre top notch as it got such great reviews... none mentioned the multitouch bug... i was planning to play a lot of games... i am so disappointed..
edit: i think the issues of htc desire should be stickied.. i can't believe i missed that issue before i was deciding to buy the desire... it's too late now... i was planning to buy the acer liquid but saw it had multitouch issue... through the forums... i missed it for desire... darn
are there some tips to avois this multitouch bug while playing games or typing on the virtual keyboard?
I tried NOVA and it seemed fairly responsive to be honest - there was a recommended control setup for the desire to help prevent the multi-touch issue - and i am sure i read somewhere a tip was to try and make sure the touches don't line up with each other?
yup i saw it... but are all games configurable like nova?

In The Netherlands we have a 7 day cooling down period after buying something or signing a contract (with most expensive purchases). In those days you can cancel your purchase for free. You should see if something like that applies where you live as well.
thx for the advice but no such thing here... anyway thx for helping.. i got the phone and yes got some issues with the multitouch... guess i will live with it.. apart from that the phone is very good!
i just played crash bandicoot warped on fpse and i mapped the x and o keys on the "search" and "back" physical keys and use the touch dpad... and works pretty good!!! i have reached the first boss level quite easily... if only all android games were that customizable!! would be able to play all the multitouch games properly
My Dad gave me his hd2, and it has the axis sticking issue, but not axis swapping. Less of an issue, but still annoying at times. (Such as playing N.O.V.A (btw, I can't find it on the market, using an apk I downloaded from some site (I hope it was a free app and that this is perfectly legal, but I'm probably wrong.) Is it still on the market? How did you guys find it?) But this phone was definately not built for gaming (adreno 200, anybody?) So it's not that much of a big deal.)
Btw, nexus gingerbread ROM, hence signature.

Casual gaming is still very possible, just don't expect halo 3 graphics. Does the hd2 have clearpad 2000? Maybe the Desire multitouch isn't such a lost cause.

Without sounding rude, it's not an issue or a bug, the bottom line is the desire dosent have multi touch, it has dual touch, the axis flipping is just a downside to that type of touch panel, it's nothing to do with the quality of htc products, as the screen is behaving as it should. so you really should of researched your purchase before you bought it.

Even though the hd2 has the same touch panel and no axis swapping issue.

how come hd2 does not have the axis swapping issue although it has the same screen as htc desire and nexus one??
Hello,
I'm excited that our Gio's have only 2 finger multitouch.
Is that possible to have more than only 2?
Thanks,
djemm,
no

Why you think no?
the hardware isnt capable of it
only high end smartphones can
Still, what use would we get of that?
Evenif the touchscreenwas capable of handling 3 or more touches, the hardware surely die on that...Just try to two-finger-largen a website whichisn't optimised for mobiles...Hardware starts thinking about what to do And doesn't finish thinking about it for longlasting seconds...
^ Good point, mate.
On a software level it can be done. I have multitouch support on me ZTE Light (single touch resistive) But it wont enable you to use more than two fingers. It'll just fool the phone into thinking it and allow apps that require it.

I don't know what sensor is in our gio but actually galaxy 3 can handle up to 5 touch points with custom kernels... not a really high-end modell btw...
As we've said previously, our phone could also handle more than 2 touches, but since we couldn't get any single use of it, but freezing the phone off, nobody yet tried to tweak it out.
Still, it's your turn to do it
on our little 3 inch screeen you dont need more then 3 fingers on your screen neither..
If you've got a question, don't post it in the Development sub-forum.
Use the general section.
Note 2 touch screen is not working? - My samsung note 2 finger touchscreen is not working while my s pen is still working I have reset it but nothing changed. No touch response yaaaaaaaaa :crying:
Factory reset. .if still no response. ..flash back stock rom
scribbled from my note 2 (N7100)
The same Problem after Falsh back in Stock Rom
I am also having this issue. screen does not respond whatsoever to finger or regular stylus input. Only the s-pen works. I too have un-rooted to see if was a software issue, and also in anticipation if I'm going to have to take a trip to the Sprint Store. Anyone out there who knows about a non responsive touch screen on our Note 2?
Michel
I have the totally opposite issue, touch system works fine but the s-pen is messed up. It probably means the s-pen and touch system works on different technologies not just one digitizer.

I am assuming that the the Note 2 has an elecotromagnetic digitizer in addition to the normal capacitive one?
Well, I just came back from the Sprint Store, and they decided to order me a replacement. Woo hoo!
