NoDo update causing multi-touch issues on the Samsung Focus?

Grant Kot from Kotsoft has noticed a strange new problem with the Samsung Focus after the NoDo update.

It appears that 3 finger multi-touch no longer gets registered a few seconds after first being recorded, making sustained touches, such as playing a long cord in a piano app impossible.

From the response to the issue so far it seems other handsets are not affected, but if you do have a Samsung Focus with or without NoDo, you can test for the problem by downloading the Piano 7 app and letting us know the results below.

Update: Grant notes that it seems the issue has been narrowed down even further to those running OS – 7.0.7390.0 and Firmware – 2103.11.3.3.  This firmware only comes with the official NoDo update and not with the hacked versions.
