D. If the problem reappears successfully, record the approximate time point when the problem appears, and wait for about half a minute to turn off Bluetooth.

E. Open the file manager of the mobile phone. There is a file named "btsnoop_hci.log" in it, and another example is the legendary Bluetooth log.

F. When giving feedback, submit the time point in the previous step together with the Bluetooth log.

When the above Bluetooth log is completed, conveniently enter * # * # 284 # * * in the dial and wait for about 1-2 minutes; To enter the file manager of the mobile phone, the correct opening path is: under the folder MIUI→debug_log, there is a compressed package with the name of bugreport in it, and this is the required log, which needs to be submitted together with the feedback.
