Nexus One multitouch problems / issues - misregistering

This video shows how my Nexus One does not recognize multitouch on the screen correctly. Two applications are used in this video.

"Multi Touch Paint" is the first. Notice how lines are drawn where my fingers have never touched. Also notice that the phone has no problem drawing straight lines when only one finger is on the screen. When a second finger is placed on the screen, the straight lines are drawn incorrectly... sometimes making an "L" shape as well. I ran similar tests on my friend's Motorola Droid without any of the problem shown here. At this time (Android 2.1-update1 on Nexus One), the Droid is much better at multitouch.

"Multitouch Vis Test" is the second application used. There should be a large dot at each location a finger is touching the screen. Often the phone will confuse where a touch is by incorrectly pairing the X and Y coordinates.

The Android 2.2 (Froyo) OS update on the Nexus is completely awesome. It is still not released "officially" but I have manually updated to it. Even with the issue I show in this video, I ABSOLUTELY love this phone. Note: I was having an issue with the power button not responding. After getting a replacement, that is no longer an issue.

2.2 is addressing this issue.

[paugren]

@stevenmottie That would be *excellent*! Do you have a source for that information? It does look like Android 2.2 will have some great improvements and added features.

@paugren well i believe its out. a manual download link can be found on phandroid, but yeh, get ur fone updated to 2.2 and try it again and post video !

[paugren]

@cdambati I have updated to Froyo (Android 2.2) and the same "issue" exists, HOWEVER... as I more carefully hold my phone and not let my hand wrap around the phone, I have seen this issue affect my usage very little. It does, however, explain why some programs using multi-touch may not function as expected.

You folks are right! The touchscreen on the Nexus One is a ClearPad 2000 wich only supports 2 fingers. The nexus doesn't have a true multitouch. Only pinch to zoom. Try any of the multi-touch apps from the market and you'll see that all fail. It's a shame. Google and HTC really gave it to the iPhone on this.

@arkv2 nope

[chrischoy9]

@stevenmottie no it doesn't, the digitizer was just designed for basic pinch to zoom, not complex multi touch

When you want to draw parallel diagonal lines it draws the neXus "X" symbol :P

@0light8dark0 Gay person.

@fusion2007 No...false hope mate. Its a hardware issue, workarounds might make the performance of the screen better but you will never get the hardware working like a true multitouch. Even still, i'd recommend a nexus one to anybody. Best phone i've ever owned.

@fusion2007 that's wrong. It's a hardware issue cause by the touch layer "ClearPad 2000" that is not designed to support multitouch.
