Black Screen at startup (necessitas Alpha 4)

[Armax]

Hello everyone,

I have got a service which starts when the device has finished booting (android.intent.action.BOOT_COMPLETED).
When catching this intent, i launch my service, do a lot of stuff, and then the service launch my qt-app.
Everything works well,  except when i unlock my sim card after my service and my Qt app have been launched.
The result is : My app is displayed well, but 1 or 2 seconds after, it seems to have some kind of reload, and it results a black screen

Have you got an idea to fix it ? Is it a problem with Necessitas ?

Thanks for your answers

Sincerly
