If you can't find and answer to your question here don't forget to use the "Search Support Network" searchbox on top right of the Android board.
1) Audio quality degrades when holding headset close to ear
2) "Insufficient available space" during installation
This is actually a bug in Android itself due to not all files being removed after uninstalling. Try restarting your device, e.g. switch off and on again. Afterwards retry installation from Android Market.
If that did not help try resetting your device to factory settings.
3) When will the next update be released?
It's Skype policy not to announce any release dates in advance. Updates will be released "when it's done", e.g. as soon as they have finished development and passed quality assurance.
4) Is it true I can enable videocalling even if my device isn't certified?
Yes, while you can enable Skype video calling on most Android phones, it is possible that the video quality may not be as good on non-certified phones. More information in our support FAQ
On Android Tablets with Android 3.x Honeycomb this looks a bit different as they are missing the hardware menu buttons. See this image for a screenshot of the menu on a honeycomb tablet:
On the bottom left corner of the screen, you can see the standard Android Honeycomb controls: Back, Home, Switch app, and Menu. In the following screenshot, the user has pressed the menu key, and hence you see the overlaid menu at the bottom-centre of the screen.
Tapping Settings brings up the settings menu for Skype, and if you scroll down, you get to the video settings, where you can enable video calling.
Part of the reason I got the Galaxy Tab 10.1 was for the videocall and the App says that it now supports Galaxy Tab. Now I am ready on these forums that it doesnt support it. People need to get their information straight and stop giving out the wrong information. If it doesnt support the Galaxy Tab 10.1 than the Android Market shouldn't claim it does. And I dont understand how video chat can be support on what seems like all other devices now except this one.
