Better yet - use the DO NOT DISTURB or turn off the cellular connection entirely. It improves battery life, avoids interruption of playback and let's you focus on your PAYING job. An employer has the right to expect 100% of your resources while on the job. Same goes for clients and entrepreneurs. I LOVE my phone - I really do ... I use it a hundred ways, but I don't text in the car and I don't have it on while performing. Audience étiquette, and mixed company behavior, in general, is very sad. People answering phones in checkout lines, at dinner tables ... without SILENCE - music is just noise. Embrace the silence and focus on the job ... not the tool.
