Wifi-Control Apps for Quadcopter Drones Contain Spyware

bitwraith writes: I've had my hands on a few cheap, ready-to-fly quadcopters (Including an Oddysey drone and a few Eachine drones), and flown them primarily using the companion smartphone apps. I often turn off my phone's wifi support before plugging it in to charge at night, only to discover it has mysteriously turned on in the morning. After checking the Wifi Control History on my S7, it appears as though the various cookie-cutter apps for these drones wake up to phone home the night after they are opened, while the phone is charging. I tried contacting the publisher of the Oddysey VR app, with no reply. I would uninstall the app, but then how would I fly my drone? Why did Google grant permission to control wifi state implicitly to all apps, including these abusers? Are the apps phoning home to report my flight history? Have any Slashdot users with other (perhaps more expensive) drones had similar experiences?
