Hi

Ive got wifi matic on my phone so whenever i leave my home the wifi turns off then on again when i come home same for my work wifi.

Now someone has said doesn't the S3 come with that function well while i was looking at my phone i have seen there is a option to switch between wifi and mobile network and also you have a wifi timer,So is that the same as what wifi matic would be doing?

While i was looking at the advanced tab i have also seen this (Allways allow scanning) does this need to be turned on?

 
Is it true it saves battery? ive been trying to find out what this does and if i need it turned on but cant find much info???
