QQ positioning function of mobile phone is not allowed.

First of all, the location is not allowed to be related to the positioning method used by your mobile phone. Mobile phone positioning generally depends on A-GPS and built-in GPS chip. A-GPS uses cellular data to locate the operator base station, so the error is generally large. It will be more accurate if the GPS chip is built in. Like a navigator, it directly locates through satellites in the sky, but it also needs cellular data. So I think you should use A-GPS to locate. This may be because your mobile phone doesn't have a built-in GPS chip, or it may be that your mobile phone has this function but you didn't turn it on, or you didn't authorize QQ to use this positioning method. The specific settings are in your mobile phone. Please take a closer look.
