Running SD on a Sony Xperia P mobile phone (highly recommended - super bright screen works well in sunlight) but during a glider flight last weekend the App crashed 3 times in 4.5 hours. When re-launching, the planned route was lost. No idea what is happening - any suggestions, or is there a way to debug?

Well done by the way for SD Cloud - I now plan my routes on the iPad, save to cloud, and load from cloud on the 4" Sony phone for navigation.
