Agreed. The 10w wireless charger can be used to charge headphones. In terms of photography, OPPO K9s is equipped with a 6400W pixel three-camera scheme, but in addition to the main camera, the other two are not very strong, with 800W pixel ultra-wide Angle and 200W pixel soy sauce camera. This price is used on models below 2000 yuan, which is also a standard specification. As long as the interface knowledge can be used normally.
