I just upgraded to FOS 21.03.0r2.
I have loaded SpiritF fromF-Droid to get (real hertzian) FM radio.
I got a message:
ERROR: Root Daemon did not start or stop after 16 seconds. SpiritF REQUIRES Root and did not get it. You need to tap System Setting -> About phone -> Build 7 times to enable System Settings-> Developers options. Then in Developer Options you need to set Root access to Apps or Apps and ADB Check SuperSU app or System Setting -> Superuser and ensure SpiritF is enabled...
OK. Developers options are enabled and I root access for Apps and ADB (I can’t no more find it today). I have SuperSU instaled.
But I don’t find where I can allow root access to SpiritF.
A hint ?
Witch app do you use for for FM receiving ?
