I listen to music or podcasts all day long at work. When I get a call, I pull out the headphones and answer the call. From time to time, I will not get any audio through the phones normal speaker. It will work if I plug back in the headphones or if I go to speaker phone. The only way I have found that will clear up this issue, is to pull the battery and reboot. It is like my phone is getting stuck into thinking the headphones are still in. Any ideas?
