Also have a look in your . . . .
. . . . menu where you will see the selection of different volume sliding adjusters.
Slide the Media volume setting up, the main volume usually does not change the
loudness of Skype ringer, because the ringer uses the Media Volume selection.
I hope this helps.
My wife and I have the same problem with the new update on our Galaxy S3's.
On all calls now it defaults to the earpiece speaker and not the speakerphone speaker. There is no icon to switch. There is no longer any "settings" when I click on the menu button at the bottom of the screen. The only options we have are to switch the camera, mute or unmute the call or to hang up.
I have to go to my profile, then click settings before I can even log out.
There is also no way to filter my contacts to have it only display who is online vs. everyone.
This new update is HORRIBLE!
Same to me...
I have the last Skype update (188.8.131.5247) installed on my Samsung Galaxy S3 (Android version 4.1.2).
When video call is active - sound isn't redirected to external rear speaker as it normally was in previous Skype versions... Sound still runs via small front phone speaker, but it makes normal communication almost impossible, at least until you attach headphones...
No switch button between front and rear external speaker on the bottom of the screen - mute microphone only...
Hope this issue will be addressed as soon as possible!
