App turning my WiFi on?

Question

Due to the time it happens, I'm highly suspicious about WhatsApp and the Drive upload function.

I put my phone in Airplane mode before going to sleep, and this is what I see the day after.

Note that my WiFi appears as OFF when I wake up, yet the phone indicates it has been turned on for the whole night...

The Drive backup starts uploading in the morning when I turn WiFi on. But I think it's around 2 AM where you see my WiFi turning on (after WhatsApp backup?)

Answer 1

On your screenshot, you have Wi-Fi enabled, even though you have airplane mode on

If that isn't the cause of your problem, background Wi-Fi scanning might be the cause You can turn it off by going to Wi-Fi -> Advanced -> Scanning always available Or for >=6.0 Android versions, it's Location -> Scanning That feature enables Wi-Fi even if you disable it
