The device is brand new and runs Android 11.
I downloaded the apk from the f-droid Web site. So far, I tried the following:
- Settings -> Security -> Allow installation from unknown sources
- enabled for file manager
- enabled for Chrome (to launch from Downloads)
- Activated developer options, turned on USB debugging
Also rebooted the device. All this doesnt help.
Any idea how to overcome this issue and install f-droid?
