Huantai mobile phone moving application is not authorized.

The solution is as follows: 1. Manual authorization: open Huantai mobile phone moving App on both old and new mobile phones at the same time, and make connection and data selection according to the concise operation guide. Before the migration, the old and new mobile phones need to be granted such rights as permission to modify system settings, open all file access rights, and allow reading and writing SMS calls.

2. Use other data migration tools: Some software does not support mobility, so you can use the data migration function of the software to migrate data to new devices.

3. Close the application running in the background: If the software has a background program running and does not support moving, you can turn on the setting function and end the software background process.
