Why can't the POCO C85 enter the file transfer interface when connected to another device via a USB-C to USB-C cable?

We appreciate your support for Xiaomi products. When sharing files using a USB-C to USB-C cable, POCO C85, as the master device, can normally identify the slave device and enter the file transfer interface, but some models cannot recognize POCO C85 as a slave device.
If you are unable to access the file transfer interface when connecting your POCO C85 to other devices via a USB-C to USB-C cable, please refer to the following details:
  1. The file transfer between mobile phones depends on the USB transmission signal parameters of the master device. It is recommended that you do not use a model with poor USB performance as the master device.
  2. It is recommended that you try plugging and unplugging multiple times until the POCO C85 acts as the master device and the file transfer interface pops up, and you can perform data transfer operations.
  3. Some data cables only support charging. We recommend that you ensure your USB-C to USB-C cable supports both charging and data transfer.
  4. Restarting the POCO C85 and the connected device will help establish a connection.
  5. It is recommended to keep your operating system and related applications up to date to avoid compatibility issues.
