If this specific patch/update is installed, the symptoms are been observed.
For any network settings change, the confirmation pop-up window flickers and vanishes before we can confirm our settings change.
The symptoms are stopping to change settings like, Select Preferred Network
Enable Data in Roaming
We have reset the network settings, reset application settings, rebooted couple of time, but the issue remains.
The only remedy is to do a factory reset, and when the system ask to update this specific security patch, ignore the same.
Because as soon as we install it, all the previous symptoms will start again.
