since an update 5 months ago my note 3 occasionally forgets my wifi passwords. Sjnce I have it set to jump to 4G cell data, I am accidentally using up my mobile data allowance.
This happens only every 2-3 weeks and I cannot find any logic to it.
Is there a way to see what has occured?
Any advice greatly appreciated.
PS. It is an Australian Telstra branded unrooted phone.
