Hi, I am the developer of the "A2DP Volume" application for Android 2.1 and 2.2. You can see this open source project here: a2dpvolume - Project Hosting on Google Code. I have also dabbled in C# development on other open source projects. My personal website is here: jimroal.com . I need some help from members to test my app. I have an original Motorola Droid, and a Droid 2. I have many friends with Android phones but nearly all of them are Motorola Droids or HTC. Because of this my app has been developed for and tested with these devices. I keep getting complaints from Samsung users as market feedback but the complaints offer no insight to the problems they are having. I just get "does not work on Samsung" or similar. If anyone out there has a Samsung device please help me test my app. I have an issues list in the A2DP volume website to post or comment on issues. I just need to know more specifics about any issues with Samsung devices running my app. market://search?q=pname:a2dp.Vol Android 2.1 version: market://search?q=pname:a2dp.Vol21 Thanks.
