This year, “USB protection” will appear by preventing attacks through a USB port. During a new connection, the function closes wired charge, including fast chargers. Due to the use of selected data exchange lines, function may affect rapid charge.
And to activate the fast charging function with this function, you need to unlock the smartphone. When connecting the device to the charger with the cable, a message may appear on the screen about the need to unlock the device. It is recommended to unlock the device during the charging process.
In addition, in the latest version of Android Canary, Google changed the application of USB protection and added the “Disable the Sound” button in the notification.
