Hello, I recently bought this phone and absolutely love it but couldn't find the answer these two questions: 1. I know the phone doesn't have Corning glass on it. How fickle is the screen. Like will it not even survive a fall from 2-3 feet? If so what would be a good tempered glass protector for this phone? Preferrably a thin one. 2. How do I make the 'Hangouts Dialer' the default app for calling? Every time I click a phone number it goes to the Dialer and then from there it only gives me an option to go through my carrier?
