We've had some issues getting the pinch/zoom (touch gesture) functionality to work on Android devices (Samsung Galaxy Smartphones; ie., S3). I'm running JavaScript API 3.5. Even the ESRI HTML5/Mobile samples seem problematic on these devices. I can occasionally zoom in and out but not all the time. Is anyone else seeing similar issues? Ideas on how to fix the problem? We've tested on older IPhones and pinch/zoom works perfectly. I've also noticed that this functionality works great on IPads.
