1. The material is not durable: the thermal induction effect of the mobile phone case drops, because the quality of the material itself is not good, or after a long period of use, the material is seriously worn out, resulting in the thermal induction effect not working normally.
2. Improper operation: When using the mobile phone case, improper operation, such as frequent friction and collision, may also cause the thermal sensing effect to drop.
3. Improper cleaning: If the mobile phone case is not cleaned for a long time or the cleaning method is improper, the thermal induction effect will drop. When cleaning the mobile phone case, you should choose appropriate cleaning tools and methods to avoid damage to materials.
