How to make Android see RTL-SDR?

Question

Android

There is a whistle RTL-SDR, there is a USB-OTG cable.
There is a non-named Chinese tablet (Android 4.4).
There is a SAMSUNG Galaxy Grand Prime G530H (Android 7.1)
And there and there SDR Touch is installed from a well-known site and a driver.
When the device is connected, nothing happens, but the light on the device is on, which means there is power.
And flash drives through the same cord devices successfully read.
A friend on the Galaxy S8, after installing the same software, when the whistle is connected, a suggestion pops up to install the driver and open SDR Touch.
Why do these devices ignore my whistle? In which direction to dig.
PS On the computer, the whistle works fine.
