After downloading and using the tubemate app, every time I click on any link, the app acts as my browser and I can't find a way to not be the default browser. I have Chrome & Firefox installed, so I'm puzzled why neither one launches when I click on a link to go anywhere online. I only use TubeMate to download videos from Youtube. RCA tech person suggested a hard reset, but the first time I did that it cleaned out all of my files including those on the sd card. I don't want to go that route again.
