I bought a Lumia 730 with WP 8.1 Update and Nokia Denim five days ago.
Every day the OS crashes at least twice a day during different operations and sometimes even when I don't actively use the phone. It reboots and things are okay again.
I'm new to Windows Phone, but I assume this is not normal?
Are there any event logs I can access to find out more about these crashes?
Or can I assume this is a hardware problem and should I consider returning the phone?
