I switched over to the GS3 from an iPhone 4, so I've had a bit of a learning curve. I love a lot of the features of the GS3, and I really like the fact that the OS is a lot more open for development than the iOS. I also really like Google Voice. However... I ride a motorcycle, so I use my phone a lot- for music and for navigation- over my bluetooth helmet. I also use bluetooth in my car, for handsfree and Pandora. Oh, and for my home phone- I've got a handheld which connects over bluetooth to my cell phone, so if I'm at home and get a call, it rings the home phone instead. And the Galaxy isn't doing those things too well. 1) Pandora isn't sending song info to my car stereo. Not a big deal, but I really got used to this feature with the iPhone. It'll send song info if I'm playing my own music, but I can't tell what song is playing over Pandora. 2) Sometimes the Galaxy seems to get confused- it'll connect to the head unit or my helmet and play music fine... but the microphone on the phone is still the one that's active. Needless to say, this makes it impossible to voice dial or control the phone- and on the motorcycle, I can't easily stop and do it manually. The only fix I've found for this is to turn bluetooth off and then on again. 3) In the house, it seems to work too well; the phone connects to the handset base, and will ring and answer just fine. But if I happen to have the Galaxy on me and I want to use it, the audio is still being piped to the handset- so if I try to call someone with the cell phone while in the house, they can't hear me and I can't hear them- I have to use the handset. The iPhone solved this by asking me which audio I wanted to use if I used it instead of the handset. 4) I've never been able to get the "listen to wake up" option to work- the only way I can get S Voice to work is to manually press the speaker button while in the app. And if I do get it to work, it still requires me to use the phone if it has any question as to what I want it to do; if I try to call my wife, it asks me which number I want to call- but it doesn't list them out, it expects me to use the screen to pick which one. This is impossible if I'm driving. 5) I almost always keep my phone on silent, with vibration. Or at least I did, on the iPhone. On the Galaxy, it's far too easy to accidentally hit the side volume buttons and turn the ringer back on. Annoying in a meeting, and really bad in the theater. I really wish it was possible to just completely lock the ringer to silent. 6) My favorite pair of earbuds don't seem to work. I can double click to go to the next song, but the volume controls don't do anything. And if I use the Galaxy's earbuds, I can't figure out how to make S Voice work- on the iPhone, all I had to do was hold down the button for a second and it'd ask me what I want- but on the Galaxy, it just seems to control the music player. So... any ideas? Like I said, I love the Galaxy for all of its power... but unless it can do what I need, I'm going to have to return it.
