in all, I just want to get rid of some of the unnecessary apps, perhaps help my WiFi strength so amazon prime works on the original browser, and increase the speed. I got the pipo today and everything is fine, I'm just trying to figure out how to use the tablet. I haven't even installed the apkinstaller. when I press install, and select where I want it(android file), nothing installs.  I was unable to find a straight forward guide or a sticky about this stuff. all help is appreciated.
