"Aggressive Wi-Fi to Mobile data handover" developer option toggles itself off on reboot

[Thwomp]

Hi there, I have been experiencing the behaviour in the subject line since installing the Marshmallow firmware upgrade. Is there any way to stop this from happening? Firmware version is 23.5.A.0.575.

Could you elaborate ?

[Thwomp]

I would like this option to remain active permanently, rather than having to switch it back on each time I boot the phone.

@Thwomp

Since it's a dev option, that's probably the reason but I'll escalate this 

[Thwomp]

Do you mean that it is normal for developer options to reset on each boot?

[Uliwooly]

@Thwomp

No, but I've escalated this, it'll probably take few days before we get an answer, you can also contact Sony directly >>> Local support

[Thwomp]

OK, thank you for your help.

That's a feature that turn off by itself at each reboot. It's not up to Sony to edit that function but Google who won't do such thing because it may drain battery and provoke high data usage.

OK, thanks for letting me know that this is a Google thing and not a Sony thing.
