Help can't figure out why S3 handset control stopped working


Hi all,
I've got a Samsung S3. I have Audio Manager on it, which has been working fine. Yesterday two things happened: there was some kind of Android update, which I accepted (I'm running 4.1.2) and I plugged in the headphones/mic that I got with the device for the first time. After that, when I tried to use the volume control on the headphones it would not work. When I unplug them and try to use the handset volume up/down side button then it does not work either. It displays the volume bar, and when I press the side button the tiny dot on the display volume bar makes a momentary jump either up or down, but then goes immediately back to the volume it was at when I pressed the button. I am not sure what I have done to mess things up...all suggestions welcome...



Thread starter
...I should add that the Audio Manager app and the audio management through the 'settings' function both work fine. But most of the time I just want to quickly press up/down to adjust volume, and not do so through an app.


share the love peeps ;)
I dont know the audio manager app but maybe on that, or another volume app, youve set it to lock the volume buttons?
