While in Android 4.3, there's a Wi-Fi related option named Always allow scanning which will allow your phone to constantly scanning for Wi-Fi networks even when the Wi-Fi is turned off. This option is claimed will be able to save more power due to the phone doesn't need to use some powers taking by the GPS to get your location information. In another side, this option also reported by some users as the culprit of some problems occurs on their phones, such as boot loop issue after restart and else. If that happen, you can easily turning off this option.

How to disable Always allow scanning option?

  3. If necessary slide the switch next to Wi-Fi option to the right to enable this option which will let you accessing the menu inside this option.

  1. Unchecking "always allow scanning" has no effect. The tablet continues scanning anyway. Worse, though it has only one possible connection at home anyway, every ten seconds, it momentarily acts as it it has no connection while it is scanning, causing programs to intermittently stop, and display a message telling me it has no connection, even though the coneection strength is always at it highest level.
