No matter what you order, the communication of the server is abnormal. There is also the inability to locate the city. . . What is the reason and how to solve it?

Hello! Please try the following methods:

1. Please check whether the date and time of the mobile phone are correct.

2. Check whether the Internet settings of the mobile phone are correct and whether the data link is open. (Note: In some systems, the mobile phone can be set to turn off the Internet access function, and only the voice call and SMS functions can be reserved. In addition, some software with traffic monitoring function will automatically disconnect after the online traffic exceeds the set limit. This situation requires the customer to set it on the mobile phone. )

3. Turn on your mobile phone and try to use different networks, such as wifi and 3G networks.

4. Reinstall the software after uninstalling, and then log in.

The default operating system of 5.5. G 10 mobile phone is 2.2. If you download other ROM on the Internet to brush the machine, the brush system does not meet the requirements of our secure communication environment, which will lead to the inability to communicate securely with the server. I suggest you reinstall the Android system.

The last one should be operated by professionals to avoid other problems; Please save your personal data before installation.
