It worked on Galaxy s8 with Android 9.0. (the last four letters of the firmware: CUD4)
  1. Photo Directory: /sdcard/DCIM

  1. File Manager +: Simple and Easy-to-use File Manager.
  2. WiFi Repeater by VPN Hotspot
    3. WiFi connecting QR code can be generated then it is easy to conncect a hotspot. Android system does not allow you to set a fixed password, which means you have to input a complex password which is automatically generated by Android.
  3. Mac Address Ghost
    4. Change Mac Address to a any specific one. Root Required.
  4. OpenVPN
  5. USB Tether on Ubuntu 18.04: use VPN Hotspot and turn on USB Tethering.
    6. See WiFi Repeater above for VPN Hotspot. All Network Settings will be done automatically probably by DHCP.
  6. BlueTooth Tether, using WiFi for outgoing path not Mobile Network.

    7. Accidentally this was found and it worked. If you use WiFi and turned on BlueTooth, the phone automatically turns it off saying you can not use BT tether when you turns WiFi on.

    1. VPN Hotspot: this is for WiFi tether. See WiFi Repeater.
    2. OpenVPN Connect: This is for tunneling. (originally I can not use ssh because ssh packet can go through the firewall, that is why I started to use a "tunneling" by Open VPN Connect). Somehow after this turned on, you can use BT tethering without the error message above, but somehow again you can not use the tethering, so turn the VPN connect off. Now you can use BT tether!
