I like to turn off wifi & mobile data when not in use to save my battery but since the last update, wifi & 4G just automatically turn themselves back on. I turn them back off but then find them on again later. What is going on? Plus my phone just restarts itself multiple times per day. All at random times. Once while I was on the phone. What's up with that?
Greetings,
I had the same issue with my device. T-Mobile doesn't seem to have
a "Connection Optimizer" feature in its line of phones. In T-mo's
case the feature that needs to be disabled is the "Wi-Fi Manager".
To disable this feature you need to do the following:
Access your T-Mobile account (for me I just press on the "T-Mobile
My Account" App).
Press the menu button on your device, then select "Options".
Under "Notifications" uncheck the box marked "Display Wi-Fi
Manager notifications".
Under "Connection Assistant" select "Open Wi-Fi manager".
Uncheck the box for "Manage Wi-Fi Connections".
That's it...
I talked to T-mobile tech support about an unrelated issue and
offhandedly mentioned this problem. The rep informed me that this
was a known issue and stated that this issue was being addressed.
In the mean time disabling the "Wi-Fi Manager" is a temporary fix
to address this problem. Here is the shorthand way to disable the
Wi-Fi manager:
T-Mobile My Account -> Menu -> Options -> "Display Wi-Fi Manager
Notifications" (Uncheck) -> "Open Wi-Fi Manager" (under
"Connection Assistant") -> (Uncheck) "Manage Wi-Fi Connections".
