Heya all! I posted this on XDA as well, but got no answer, everyone is a bit stumped. Around three days back, phone started picking up incoming calls on external speaker, the on-screen button, after swiping to answer the call, is depressed. I need to press it again and transfer the call on the internal speaker. Only thing I've remember to have done when this happened was the fact that I was listening to music, through headphones, on Walkman app, when phone rang, and answered it, and used the headphones for that call as well. To temporarily fix this, I plugged headphones in during a call, and then took them out. For the next three or four incoming calls, everything went back to normal, but today, one incoming call was also on external speaker. Someone suggested it was the Socialife update that brought this, while another user said it wasn't so since he had the app disabled, and phone still behaved strangely. I mention I am on 4.3, the .290 version, unrooted.
