This is a question I asked my self several times. Upon You Tube watching it seems that it depends on what Glass protector you have installed. Guess in short it's really trial and error. Most glass screen protectors lift up due to the fit of some cases. Some cases fit and are molded differently than others. In most reviews I have seen, the glass protectors do lift up. The S7 edge is a sight to bbehold and should be showcased whenever possible. I understand the need for protection but just a thought. We invested hard earned dollars on our cellphones so why limit our experience with a shield. Yes, we should protect our investment but what's the use if we never really enjoyed it fully.
