Hallo guys, i have only problems with Android mobilephones. I test a HTC Desire, HTC Desire HD and Samsung i9000 (Galaxy S). All with Android 2.2 OS. The Connection with the phones is still no problem. I can recieve calls or make outgoing call to another peoples. But, if i do that, i hear the people only for 1 second and than is all dead. i don´t hear the people and he can´t hear me, too. I Try with my old phone (Samsung i8910 with Symbian OS) and this phone is perfectly work... my old Palm Pre, too! Only Phones with Android have this problem. So, i think its a Bluetooth problem on F910BT. M
