Game not starting on Samsung Galaxy S2

My Android game is in development. I have tested many builds successfully before on my Galaxy S2 as well as other, newer devices. However the most recent versions have failed to start on this device. They still seem to run well on other Android devices, and in the web player as well, but on my Galaxy S2 I cannot even get as far as the Unity splash screen.
I initially suspected that the issue is with my device, and have gone as far as to do a factory reset - wiping all of my applications and data - and the game still won’t run! Please help. This is making things very hard for me…

The issue was with Unity 4.6.1 and was resolved by patch 4.6.1p1
