i took off my otter box caseI noticed that my picture quality had diminished a lot with the clear plastic over the camera lens... and that with the power support screen protector and the plastic screen protector on the case was also diminishing my screen quality
I really love this case and I am still debating whether or not to reinstall it on my now NAKED iphone.
Anytime you install a device into a protective case, you invite some possible diminished functionality.
The more protective the case, the more likely you will see some adverse indication.
The alternative is diminished protection, you know how you use your phone and where you take it on a regular basis so you have to decided on what compromise to make.
If you work/play in harsh environments you might want to side with max protection.
Work in an office with carpeted floors all over the place, live a docile lifestyle than GO NAKED.
Work in a garage, ride motorcycle off road than you might want to have MAX PROTECTION.
