My S3 should be here tomorrow. The handset is a little larger than I would have liked, but I've been told by many people that the phone is pocket friendly. I've upgraded from a HTC Desire so I'll be interested to hear from anybody who has made the leap from a HTC device with Sense to a Samsung handset with TouchWiz. Any hints and tips before I get the phone are most welcome! Is it better to leave the phone switched off and give it a full charge before touching it?
