I'm using Ubuntu 20.04 on dual boot with Windows. My problem is, I cannot use USB tethering in Ubuntu but WiFi works fine. On the other hand, windows works well (both USB tethering and WiFi works well). There's one more thing. If I use any other mobile phone (Samsung) with USB tethering its works well in Ubuntu except one mobile (also Samsung) but that works in Windows.

I tried to update drivers with software setting additional drivers tab but it shows "No additional drivers available." When I use lsusb it shows:

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub            
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub          
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub           
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub            
Bus 001 Device 005: ID 04e8:6863 Samsung Electronics Co., Ltd Galaxy series, misc. (tethering mode)                                              
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub           
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub           

and on ip show link

usb0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN mode DEFAULT group default qlen 1000
    link/ether 2e:2e:c1:b2:62:f3 brd ff:ff:ff:ff:ff:ff
