I have recently picked up an optimus one and it works great for the most part. I have a blueant supertooth3 which it seems to work very well with, except the volume of the voice prompts is too low to hear well. Not sure if Im referring to this correct, but when I say something like "call Mary mobile", the voice it responds with to confirm the contact is correct is too low. I cant seem to find away to adjust the voice prompt volume on this phone - is there? Volume of the call is great, and volume of the prompts from the supertooth itself is great, its just the voice prompts through the phone.
