I used to have a Lifeproof case and mount for my old iPhone 4. Loved it. Secure and simple one-handed operation.
Does Anyone use the X-Grip by ram mount?
I'm still hesitant on pulling the trigger on one and putting my Note2 in it
This is what I use now. I was hesitant at first too but the X-Grip has been 100% reliable since I bought it a couple years ago. Just make sure you get the correct size for your device. There's a jumbo sized one for phablets that won't work so well with normal sized phones.
