Samsung Galaxy S Advance (19070) headset volume

[Guest Redparrot]

The headset volume on this is far too low. I've done a search on Google which only returns results for the service code the S2, so I've tried this code, but it shows no audio options. Does anyone know how I can increase the headset volume on this? Thanks.

Try downloading SamServMode in the Play Store.

Thanks for the suggestion, but unfortunately it doesn't work - I just get a black screen with a title when I start the app.
