Got new otterbox case yesterday for my white iPhone 4, hoping I wouldn't have issues like I did with another cheaper brand. But, it started again! I've installed a call lock application but still have some issues. Any hints, tips or fixes? I really love this case, so I hate to give it up, but if anyone knows of any alterations I can make in this otterbox in order to keep it or can recommend a protective case that won't cause these issues, please let me know. Thanks!
