Troubleshooting android fragmentation

Hi everyone,

I’ve just released my app (off-market: http://cookers.io/download/) but some users have problems launching the app :frowning:

The only thing I know is that the screen stay white and the app doesn’t load.
The user use a wiko cink slim with android 4.0.4.

I use tracking in the angular run method waiting for $ionicPlatform.ready and I track JavaScript errors with window.onerror and angular $exceptionHandler but I didn’t receive anything from this phone… :frowning:

Any idea on how to get clues to solve this problem ?
Have you ever had some loading issue on particular phones ?

Thanks
