V2.4
According to the latest Google guidelines, the user
must explicitly authorize access to an external Folder

So a dialog is given to select a folder to store your data it
can be any name but RdScanPro is a preferred name.
Tested ok with android 5-13.

You also will be asked for permission to record audio according to the latest Google guidelines, the user must give runtime permission if the audio jack is used. (Allow record audio.)

If the audio jack is used to decode Pocsag then Android sees this
as Record Audio but nothing is stored on the phone ,it is decoded.

This app needs a small OTG cable to connect the scanner to your phone or tab.

It's best to first try the free app RadioScanUBC125 to check if your device supports the use of this OTG cable.
