Is constantly scanning wifis, even when Wifi is off #41

Closed dicer closed 8 years ago

dicer commented 8 years ago

I'm on CM13 and have a problem with Privacy Police 2.2.3 (from fdroid): The app is constantly scanning in the background. So even when wifi is completely disabled, it keeps scanning every few seconds. Might this be, because I have background wifi scanning always enabled?

Here are some logs:

Actually: When I turn Wifi on, the errors stop, but it keeps scanning:

Hi Felix! Thanks for catching this!

It indeed seems to be related to the case where background scanning is enabled. I'll fix this in a future release, but it shouldn't be a major issue (all networks will be disabled when Wi-Fi is disabled, which should be desired behavior).
