Hello. I've tried to connect Huawei E3372 dongle to Joying Head Unit running Android 8.0.0 PX5 Octa Core. When I plugged it in it wasn't detected by the Head Unit. So after looking for a solution online I've rooted my head unit and installed PPP Widget 3, but still the dongle isn't detected by the head unit and PPP Widget 3. A light on the dongle flashes when it's plugged into the head unit the same way it's flashing when plugged into a PC. When I plug the dongle into a PC it opens up a browser window with HiLink.
I've read the PPP Widget 3 description in Play Store where it said it was tested with Huawei E3372, so is the head unit the problem?
Is there anything that can be done to make it work or should I purchase a different dongle or maybe go for a Mobile WiFi Router?
I would really appreciate it if someone could help me out what to do next.
Also I'm sorry if I posted in the wrong section of the forum.
