HTC G 17 weather forecast update prompts that the current position cannot be detected. I hope to answer at a high speed.

This is what happens when you use accu, right?

Accu weather sources officially used by htc are basically updated by 3g or wifi.

Location can't be detected. Manual addition can update the weather.

Now consider that your location can't be detected, such as gps detection blind area, inaccurate network positioning or timeout.

Since you can add it manually, add it manually.

To update automatically, you only need to uncheck "Automatically detect my location" in the weather and settings.
