How to treat the necessity of mobile phone case and film pasting?

This is necessary. I have verified the protective effect of mobile phone case and film. It's really easy to protect. Let's talk about the film first! I like listening to music and radio programs with headphones. Listen to headphones while charging at work, and put your mobile phone on the desktop. I forgot to get up quickly with my mobile phone several times. As a result, the headset flew out dragging the phone and was pulled back by the charging cable ... I fell face down to the ground with a bang, and if I hit the original screen directly, it would hurt my heart.
