@computertech1012 hi! really thank you for this! I'm giving my suggestion. I think that instead of media tab only, for eas of access, move the webcam controle to the globel bottom grid beside my seekbars and buttons for speaker and microphone. Because this section is available regardless of whatever tab is selected. Lets keep media tab just for viewing videos

Hi,
@amirmahdifard Thank you very much for the suggestion, and also thank you for your contributions to the Android client too.
That makes sense, and I agree that moving the webcam controls to the global bottom controls area would make them easier to reach while keeping the Media tab focused on viewing videos.
I will work on that shortly.
Thanks for reading!

Hi,
@amirmahdifard Thank you again, and also thank you again for your contributions to the Android client too.
I have now moved the webcam controls to the global bottom controls area, and the Media tab is left for viewing videos.
If you get the chance, could you please test it and let me know how it feels?
Thanks for reading!

sure! don't worry. I have android device and i'm free all day. I'm interested to do all the tests if you're willing to help with the android project because in teamtalk android I was alone working all these times, That's why I became so happy when I saw contribution from you!

@computertech1012 bro sadly it's stil the same. Clicking on server to login, On my laptop it says my phone is logged in, but in my phone it freezes right after clicking on the server and after a fue seconds, it says teamtalk is not responding, close the program or wait for responce.
