Multitouch not working on Hero

Finally with this Eris leak we can have a stable working 2.1 ROM on the Hero. But I'm terrefied to find that true multitouch does not work on the Hero. I've tried multitouch paint, pong multi touch, Multitouch Vis Test, Multitouch visualizer and they all fail miserably. You can twinch, but that's about it. If you try to cross axis'es with the two fingers the reading get stuck.
I hope this is a driver issue and not a hardware limitation of the Hero, but I suspect it's the latter
Perhaps this is why HTC has delayed the Hero update so many times, they franticaly try to find a fix for this issue.

It is a problem with the HTC sensors and is the same on all HTC phones with touch screens
It is not likely to be fixed ever.

This should be fixable, because it works fine on AOSP 2.1 roms, even on a Hero...

then how come it can't be fixed on the nexus one?

AH I missed that issue, dont know anything about that.
I was talking about the fact that multitouch doesnt seem to work in the current leaked build in Maps. This leads me to believe that they havent implemented the native 2.1 multitouch.

we were talking about the inherent problem with all htc multitouch devices, it works for pinch zoom ok but when you get the "touch axis" too close the phone becomes confused over where your actually touching the screen.

Maybe a hardware problem fixed on HTC Desire? Or HTC Market?

Its very unlikely to get fixed it is just how htc do things. They might change it for the furture but devices already out are stuck like it.
Motorola have it working fine though.

Is true dude.

I think Google underestimated the usefulness of multitouch. It makes the whole mobile phone experience much better. Keyboard works better, games can be more fun etc.

Apple: I'm suing you stealing our patented multitouch functionality.
HTC: No, we didn't. See? Our multitouch doesn't work.

Isn't there a fix for multi-touch axis flipping

Now Google maps 5 is out and rotation dosent work, I was wondering about it and remembered that a website had said a member of cyanogen had fixed the axis flipping on the nexus I don't know if this was true, any idea ???

I seem to also remember something about this...?

Jesus, Google says that his beloved N1 doesn't support it and you want a fix. Here+s a fix : sell the Desire and get a phone with the full multitouch capable panel.

A colleague of mine has a Desire with a rooted ROM (a Sense 2 one) and the rotation works.
So yes, there is a fix.
I hope that HTC will officially release a (Sense 2) upgrade for the Desire, and that will contain the fix, I don't feel like rooting.

O rly.
FYI Sense 2 is the version that shipped with Desire. If you mean the newer Sense, that's on the Desire HD, that's Sense 3.
Which ROM is that again ? And please let him install http://www.appbrain.com/app/multitouch-visualizer-2/org.metalev.multitouch.visualizer2 and make a vid of the "fix".

Maybe Google maps thinks the phone supports multitouch as its a dhd rom and activates the option to use rotate. Rotate should still work...but because of the dual touch 'bug' it will get it wrong some of the time.

Yeah, I remember reading about a fix included in the core, but it was disabled. How would I enable it?

Can't we get the apk which is getting installed on the DHD?

I've read about this after some issues with Nova, which I guess is why it isn't supported anyway. The screen itself is not multi-touch and is apparently dubbed "double-touch" and the axis switching is hardware related, however there is a setting buried somewhere in the Android SDK that was designed to only be enabled for a certain device. Enabling it on the Desire, however, was supposed to alleviate some of the issues with axis-switching, although not a total fix. It was mentioned that CM had this setting enabled on their ROMs for Desire, but whether that is still the case I cannot say. This is just from memory, I'll have to do a bit more digging to refresh my memory.
EDIT: Asked around on the CM IRC and that particular 'feature' was indeed pulled, however was reinstated a few days ago, so probably only on the nightlies for the moment.
EDIT 2: Flashed a CM nightly and it doesn't appear to have made matters any better

Yes the multitouch is indeed enabled in maps on dhd roms, but the problem is not fixed. You can easily see, when your cross the axis with your fingers, and it definately still doesn't work well.

Yes, this issue is very irritating when playing games like SliceIt as well.

The touchscreen hardware is only capable of determining the rectanlge containing the 2 touched points.

If the desire screen is capable of detecting two fingers as long as they don't cross on the y and x axis, two finger rotation should be more than possible on google maps just as long as you keep the rotation no larger that 90 degrees between the y and x axis and even then it should only cause a "hickup" in the rotation so although it won't be great, if active, it should be ok for use!

The two touches is not what bothers me it is the axis flipping that's annoying I will try to flash a nightly and will see what happens.

There's a nexus one two finger fix. Don't know of adesire port of it.
In nexus one development section.
Desire is the source of all suffering.

Has anyone found a fix for multitouch on the desire yet?
i found a link(http://forum.xda-developers.com/showthread.php?t=767654&page=4) to another post on fixing multitouch on an acer liquid sharing drivers for developers, so can people please take a look and see if something can be done for the desire?
thanks in advance

Have you read the lasts posts in the thread you quote ?

[Q] Multitouch Axis Problems

I'm not sure if this was asked already but, I was wondering If someone could fix the multi touch issues of the mytouch slide. It has the same exact problem as the nexus one/htc desire etc etc.
Problem -- http://www.youtube.com/watch?v=qzhUzq6bTPg&feature=player_embedded
The LG optimus one seems to have a work around for it and i was wondering if someone could bring that workaround to our phone. http://www.youtube.com/watch?v=5Ur9n9pQUAg

Same!!
Did you ever solve this problem. I'm having the same issue because I can't pull down the notification bar and also whenever I switch to another screen the notification bar comes down lol. But other have fixed this problems somehow with a kernel

I really wish i could solve it haha, and yea crazy stuff like that happens sometimes. Multitouch is definitely also a problem with 3d shooting games. I was actually hoping a dev try to fix this problem. If there is a fix/workaround for other phones, then its definitely possible on this phone.

Nothing you can do. It is the sensor in the phone. It was never meant for multi-touch

I'm not sure if you've clicked this link that was posted in the OP http://www.youtube.com/watch?v=5Ur9n9pQUAg, but it shows a clearpad2000 device with a mostly fixed multitouch axis. According to the OP in this thread, its done by inverting the inverted axis http://forum.xda-developers.com/showthread.php?t=933686

I was checking out those links. Seems that those fixes are only half working.
It really is a hardware problem. They're just recompiling the kernels to clean it up so that it looks like it works properly, but even in the videos it's evident that there's some messing up. If I'm reading right, our phone probably has the same controller as the G1 and N1. And newer phones don't have the problem because they have better hardware.

Yes I realize this is a hardware problem and that this is not a complete fix, but its better than not having any kind of fix at all.

I had the same problem, was really annoying when playing multitouch games like PewPew because it would sense your fingers opposite of where they were and the axis locked during multitouch which makes fine movements impossible. The newer 4 and 5 point multitouch screens perform way better.

ICS Video camera

Quick question - now that the photo camera on ICS for Desire Z is mostly working, would it be hard to get it to make movies?
I have no idea how hard this is to do. Just asking

You'd have to write the code.

I am not a developer, but I am certain that, yes, this is a very hard thing to do and I really haven't read anything about progress in this regard, since zbuw came up with the initial workaround to get the camera partially working.
The main problem still seems to be that, so much code has changed in ICS that we basically need new drivers from htc or qualcomm in order to get it fully working. I expect that we won't see full camera functionality until a leak comes up from which we can extract the drivers (I don't know enough about the similarities of other devices, hardware-wise, to guess on how likely this is.

That's normally fair game but you're replying to someone who can't even post in the dev section yet, don't make him download backup wipe flash discover it isn't working then restore.. no, to the best of my knowledge (having just tested it and seen it reported elsewhere) recording does not work at this time (unless some wild development has happened in the past couple days).

thanks. I will give that a shot. I kinda need video recording working from time to time, so it will be painful running ROM without it ... is that true that none of ICS ROMs have the video camera working (just pic taking)?

From everything I have read either here or CM, what I believe they are waiting on is drivers from either HTC or Qualcom to further develop the camera. I believe they have it working somewhat. I am NOT a dev by any stretch just passing along what I have read.
Hope this helps

Yes this is true, and even picture taking is iffy at best (you have to install third party app and most people can only take non-buggy pictures at VGA (really low) quality)
If you need video recording AT ALL do not use ICS yet.

thanks guys, those statements change the ground. in fact I will wait a little longer until those drivers get released and developers can fix camera issues.
I use camera for pics often and videos occasionally, so I wouldn't like a phone like that at all.
also, what does it mean that GPS is "kinda" working now (Andromadus v10), it's broken or not?
I use Google Navigation frequently whenever I get lost or traveling to current closest (unknown) chain store location and such ... and I kinda rely on that ... I guess I need to wait for a beta ROM, alphas are not for me yet.

I still think you are putting too much hopes in Google translate. You won't be able to participate in forums like this unless you find someone who has some basic english literacy to translate for you
I see you are talking about camera preview not working, but that is to expect I suppose from a beta rom which is still below the usability threshold.

No way to English level is not good, only with Google, the hope can communicate with everybody, I will try to find a better translation

maybe I'm missing something, but I don't get why ppl are getting so hung up on the ICS camera bug. Surely in the grand scheme of getting ICS on our desires, getting a stable, usable platform in place is more important than a camera.
