Almost from last three months I am using the ndrive navigation service on my mobile. From last one week I am facing lots of problem in it. Some time I am not able to open the maps of the navigation and some time application restart automatically. For removing the problem I had also reinstall the application software but problem still not fixed. I had also restored my mobile in the factory mode but problem is still to fix. So I want to ask from you guys. How I can fix the problem? Any quick answer will be deeply appreciated.
