long loading time android

Hi,

We are having an issue with application load time on android devices. Its an app built on unity 4 and we ar eusing vuforia in it. We tried to use unity profiler to see what strt up times are like but all unity scripts initialize like withing 1 seconds. Profiler does not show any output until splash dissapears which is about 40-50 seconds on Samsung Galaxy tab2. We then checked logcat in eclipse and loading libs seems to be quite fast but there is like 30s long gap with no messages in between these lines

Any idea how to track down what is going on there? I'm attaching full log since app start until splash screen gone. LOG HERE

Thank you for your help
