Hi all,
I am facing a trouble with my developed 3rd party app.
The problem is that the device is hanging up at the start up (logo is displayed without any progress).
The app is making some business at the start up.
The business is:
1- Access the Persistent Store
2- Access the internet
After installation, I can use my app without any problem But,
When I restart the device, the app is performing the above business and hangs up.
Note:
I am working on 8520 OS 5.
Please help me.

You need to check the Developer section.

Remove that app!

Does your app wait for startup to complete before accessing the internet? Auto start applications are launced before the device is completed starting so you can finish initialization before the user can access the device. But that means your application needs to be well behaved.
