Since the Nougat update I've had a change in behavior when it comes to Bluetooth and airplane mode.
On Marshmallow, the state of bluetooth was not modified when turning on airplane mode. Now whenever I toggle airplane mode (either turning it on or turning it off) my bluetooth turns off. Is this the expected behavior? I preferred the old behavior, as I have a Gear S2 watch and want it to always be connected. My first two days with Nougat caused very high battery drain in the watch because I didn't realize that turning Airplane mode OFF would also turn Bluetooth OFF.
At least I can understand turning bluetooth off when Airplane mode is turned on, but why would it ever be turned off when turning airplane mode off? For now I'm using Tasker to solve the issue, but I feel like this is a bug that shouldn't be happening.
In the mean time, though, for anybody else who is curious, I was able to solve the problem and essentially modify my airplane mode button to only disable the cell radio, wimax, and NFC while leaving WiFi and Bluetooth on.
I removed wifi and bluetooth from the airplane_mode_radios variable using ADB and now I have the behavior I want, even if it's not the "correct" behavior. This also seems to have fixed the problem of bluetooth turning OFF when airplane mode is turned OFF, so I'm happy.
The reason I care about this is because my office is in the middle of the building and I have no cell service, so in order to prevent battery death I have to turn airplane mode on every day when I get to work and then turn it off when I leave, and I really only want the airplane mode button to function as a "cell radio off" button, which it now does. If I need to fly, which is rare, I can turn all of the radios off manually.
UPDATE: I cleared my cache partition and this odd behavior seems to have stopped. I will update again if anything changes again.
UPDATE 2: After a few tests, the behavior has returned. When I first rebooted after clearing the cache, I turned off airplane mode and bluetooth stayed on. I then did it again, and bluetooth started turning off when airplane mode was turned off. This is NOT the expected behavior, and why is it not behaving consistently?
I'll have to test this specifically on one of the Nougat devices we have here at the office. We have an announcement thread that we've been centralizing all this information to. If you haven't had time to check it out, here's the link - [Announcement] Nougat 7.0 Update Problems *UPDATED 03/08*
