Installation instructions:
-Remove the outside layer carefully by hands. (Do not use tools to prevent damage)
-Open the inside shell by separating the two halves at the tabs as arrows pointed.
-Place the phone between the hard plastic halves.
-Click the hard plastic case closed, and install the outside rubber case.
***(The screen protector can be peeled off, so the case can be used with a tempered glass screen protector if needed.)
***(Peel off the plastic screen protector if you have tempered glass installed on your phone already.)
**If the screen protector has separated from the case during transit, it can be easily reattached and is not defective. Your phone holds the screen protector tightly in place when installed.
