I’ve never used any of the Android radios before, so I really don’t know the quirks like the time problem. But having something like GPS would allow for a way to set the clock, assuming the Android portion is rooted. If your newsmy only supports 4.2.2 that’s getting pretty old. That is the current minimum sdk I’ve got set, and occasionally I’m running into issues with wanting a newer version.
Resolution is one of the issues I’m thinking about. If I had a “Supported” device, like maybe the Newsmy, then things would be tailored for that screen. I’d like to offer layouts for different screens too, like portrait and 10″ tablets.
