i have this issue - if playing music/making a call via headset/headphones and unplugging them makes the phone not to recognize the unplugging and it keeps using the 3.5mm jack as output/input. this causes the situation, when making a call or listening to music/radio is possible only via headset/headphones. i do not know exact steps how to make the phone recognize i have unplugged the headset/headphones. sometimes it happens by a miracle that it recognizes it. plugging and unplugging the phones jack, restarting, starting and stopping of walkman... i try always all possible stuff, but sometimes i cannot find the right thing to do even whole day.
i have Xperia T, previously 4.1.2, now 4.3 (.199) - it kept happening previously and now as well...
I WILL APPRECIATE ANY HELP / SUGGESTIONS
Thank you all in advance
