[Q] The "Dual-touch" after froyo update

---

Hi guys, ever since I updated my Desire with Froyo (OTA) I've experienced a "bug" in the "dual-touch" that the Desire has.

The problem is when you are dual-touching and hold the first finger absolute still and remove the second one, the touch of the second one stays on until you move the first finger.

Which isn't a big problem until you play a game where you have to hold one button and steer at the same time.

Link to a crappy video to show my problem: http://www.youtube.com/watch?v=3eLYfHGeFnY

Now to my question, is it only me who is experiencing this kind of problem? Could this be fixed with a bakground app that checks the touch screen (when the second touch leaves the screen)?

/Oggeh

Same problem, i think is "normal" for the desire...isnt a multitouch screen..is an emulation and of course dont work properly..

Sent from my HTC Desire

But I don't recall the Desire having that problem before Froyo :/

the desire dosent have multi-touch, it has dual-touch, basically the way this works is, the desire's screen can only physically detect one finger touch, when you touch the screen with a second finger, although the desire can detect that a 2nd finger has touched the screen, it dosent know where that 2nd finger touch is, it then uses a mathematical algorithm using 3 points of reference, to work out where the 2nd finger is ..........

ok this is problematic in FPS games and games like meteor blitz

something i noticed though, on my previous amoled desire i had the official screen protector installed so i never noticed the problems in games

now on my new handset still unprotected, multi-touch games struggles a lot more

can anyone else confirm if their experience is better with the screen protector?

My bad, I thought people like you would understand when i wrote "multi-touch" in the title. I will certainly swap it out ..........


On Topic: Do you guys think it's any idea to start a conversation with HTC about this or is it just a waste of time??

i understand what you ment, i was correcting you because i thought you didnt know, btw its not a bug, the symptoms you are describing are what happens with this kind of touch panel........

Even though I didn't notice this kind of bug before Froyo update? I mean, did someone experience this in 2.1?? Before Froyo it was possible to play games, emulators etc.

And yes I know that the Desire don't have the best touch sensor.

yes it happend with eclair, its because, imagine when u touch the screen with one finger, the screen detects it yeah? when u touch it with the second one the device see's it as one big finger touch, and then uses its reference point to work out where the 2 fingers are, now when u take one finger off again, because the first finger is still touching the screen it dosent realise because it cant phyically distinguish two fingers if you get what i mean lol

Ok, but I'm still not convinced, is there any video of the problem with Eclair or even on a Nexus One with Eclair/Froyo?
