I've had the Trident for 6 months. It's definitely bulky, but I'm the kind of person who drops my phone way too often, and the case has absolutely and completely protected it. Someone even spilled a large hot chocolate onto it, and after drying it, washing all the non-electronic stuff, and ricing the phone and battery, it was like new. That was months ago, and I've had zero issues.
And definitely no problems with freezing. Unless you're doing some serious overclocking, there's no way your case should be locking up your phone.
