Will the bulge on the inside of the phone case crush the keys?

According to Zhihu's inquiry, the bulge on the inside of the mobile phone case will not crush the keys. The bulge on the inner side of the mobile phone shell is mainly to protect the mobile phone from external impact or friction. At the same time, the raised part can increase the grip of the mobile phone and improve the comfort of use. In addition, the design and material of mobile phone keys have also been strictly tested and selected, which has certain compression and impact resistance. Therefore, even if the inside of the mobile phone case protrudes, it will not cause excessive pressure or damage to the keys.
