I can make and receive calls on my Dogwood phone. It works quite well when using headphones, but there are some problems:
- using the speaker phone, the other party hears their voice echoed back after approx. a second
- sound level is a bit weak
- Bluetooth headsets only work for sound playback, not for calling
- I have issues with the proximity sensor leading to lots of spurious touch events when using the phone’s earpiece
- phone drops to 2G during calls, cutting all internet access
- I keep forgetting the mic kill switch, because there is no indication in the UI
SMS works, too. Haven’t tried MMS.
