Summary of this issue

1. Taking photos with your mobile phone facing laser lights can easily damage the camera. The lights of scenic light shows, stage lights at concerts, "colorful lights" in discotheques, portable laser pens, laser cat toys, etc. are all laser lights;

3. Keeping the phone charged too much or too little for a long time is not good for the battery. It is recommended to keep the phone's battery between 40%-80%. There is no big problem even if you charge it frequently.

4. Although the tempered glass film white edge liquid can temporarily eliminate the white edge of the phone, it can also easily penetrate into the inside of the phone and damage the phone. It is best not to use it.
