Note3 Is the weather on the desktop updated automatically at regular intervals or do you need to manually press the refresh button to update it?

It will be updated regularly. It can also be understood that if the server has updated weather information, your mobile phone program will be updated accordingly within a certain period of time, but it should be noted that traffic will be generated during this period, and automatic update will also connect with the server from time to time to generate traffic. If you like to use it, don't close the corresponding program. If you don't want to use it, you can turn it off. Of course, you can also install mobile phone management software to turn it off.
