*Precautions*
1. It is a normal physical phenomenon that there are bubbles in it. All liquid phone cases will have bubbles when stored for a long time or used. There is a compartment inside, when the weather changes heats expansion and contraction, and when the cell phone has a body temperature, the compartment will rise and bubbles will appear when the temperature is high. Leave it alone for a few days and it will be fine again. Or put it in the refrigerator for a few days.
2. The process of quicksand cases is more complicated than that of ordinary cases. Each case has an injection molding port and has slight flaws and normal traces.
