Dumb question: have you tried using TeraTerm on a PC to talk to your Nano via the console?
If that works, then refer to the following thread and see if your phone can talk through a terminal app...

Two apps
Three OTG adapter caboles
Two phones
Two USB cables
Zero luck.

Here is my Willkac cable working with a Moto X? to the nanoVNA. The X is running Android 7 and asks if the nanoVNA should be allowed to use the USB when it is connected. The NanoVNA app just works without fuss. Note that the Wiilkac cable is a standard type A USB 3 socket not type C.
