I'm using for the moment a flip case from Head Case. They look pretty nice but I don't recommend them. Got it for a month now and it's already all messed up, ready to be thrown to garbage.. The plastic that hold the 830 is already cracked from all side, the simili-leather is already cracked and near ripped-off. They also don't work when using a Qi charger. I have to remove the device from the case. Already ordered a Nokia flip case with Qi back cover.
