The Galaxy S4 has a 13-megapixel rear-facing camera.

Samsung is holding a contest to encourage developers to create apps for its new Galaxy S4. The latest phone in the Galaxy line was announced in March and, as of last week, will also be available with stock Android 4.2 through Google.

According to the Wall Street Journal, Google's developer contest is looking for apps that will work with Google's file sharing Group Play service. Google will reward the top 10 winners with a shared $800,000 cash prize: first place gets $200,000, the next three get $100,000 and the remaining six receive $50,000.

Because app makers are encouraged to incorporate Group Play, we can look forward to some innovation in Android-to-Android photo sharing applications. Last year's Samsung app challenge contest was won by the violent "kill all the terrorists" game Gun and Blood.
