HTC One series: weather not available - what to do?

If your HTC-One shows the "Weather not available" message, there can be several reasons. We'll show you how to solve the problem.

Update: Open the weather app and activate the option "Update automatically" in the settings.
Restart: If the problem has only recently occurred, restarting the device will help in many cases. Small errors in the buffer are thus deleted.
Cache and data: If there is an error in the weather app, you should delete both the cache and the data. We show you how this works in this practical tip. In step 3, select the weather apps instead of the play store.
GPS: Of course, you should also activate GPS location. Open the "Settings" app and switch to the "Options". Under the "Location Services" category you can now enable "Access to my location".
Background data: In order for the weather to be displayed even if you have not opened the app, you must activate the background updates. To do this, open the "Data usage" category in the "Settings" app and select the weather app. Deselect the "Restrict background data" option below.

In the next practical tip, we will show you how to restore deleted files on Android.
