Having trouble with my iPhone 5 protective case

[ALUXi33]

I bought my iPhone 5 16gb white about 2 weeks ago. I purchased a screen protector from Target. To make long stories short, the screen protector covers the sensor and when the phone gets low on battery it's touch screen is not reliable. Is the phone no good or is the screen protector causing this?

I bought this screen protector: http://www.target.com/p/belkin-3-pa...-f8w179tt3/-/A-14299085#?lnk=sc_qi_detaillink

Does anyone have the same model and with a screen protector that covers the sensor and everything works?

My phone looks like this minus the case:

That picture looks to be using a Spigen Glas t.r screen protector. We know what an iPhone looks like. You don't need to post a picture of it.
