I need your input on a very peculiar problem that I am having with my LG Quantum. I had upgraded my phone Mango (7.5) when the update was made available on Zune. However, some time after upgrading i encountered frequent random restarts. The phone would go back to the LG screen and restart. This happens only with apps downloaded from the marketplace and it usually happens either when i have started a new app and it is loading information or when pressing the back button when an app is loading or accessing information from the internet. While i was typing this i gave it another go by starting up the "Reinstaller" app and it boot back to the LG screen once again.
I have given this multiple tries by downgrading to Windows Phone 7 (Nodo) - no restarts and the updating to Mango again - it restarts. So i think the issue is with Mango update. Any ideas what could be the problem?
