22 Apr 2026
| Many users who come into contact with this three-layer anti drop shell for the first time may mistakenly think that "the size is wrong, or they bought the wrong model", but in fact, it is due to the incorrect installation method! The correct installation steps are as follows: Split the phone case: Completely disassemble the phone case into three independent components (PC hard inner shell, silicone buffer layer, hard PC outer shell). Fixed phone: Place the phone smoothly into the innermost PC case, ensuring that the camera and button holes are perfectly aligned. Assemble the middle layer: Assemble the hard PC inner shell and PC outer shell, press the buckle to ensure complete fit. Install outer layer: Insert silicone layer. Check details: After installation is complete, press the four corners and all buckles to confirm that there are no curled edges and that the button rebounds normally. 💡 Small Tips: The buckle must be pressed to the bottom, otherwise it will curl up Don't forcefully break it when dismantling, just pry it open slowly from the gap at the bottom After installation, check the buttons and charging port. If they do not affect use, then it's OK!
