The phone fits in well so I would say yes, they are compatible as long as the screen protector is installed properly because the case don't cover the 0.4mm thick glass. So the room for error of screen protector installation is minimal. Otherwise, the case will raise the screen protector a bit causing tiny bubbles underneath.
Although it just fits in CandyShell case, I will recommend you to use SGP's or other bumper style cases with the SGP Steinheil GLAS.t screen protector. That will gives you a peace of mind.
