Hello,

I received my new Samsung Galaxy S7 edge today and I have a couple of question's.

1) when I try and use the app 'knox' I get told it's unable to work due to a custom binary. What does this mean and how to I resolve it?

2) when I insert my Giff Gaff nano sim into the phone, it's not recognised. Instead of having signal I just get a circle with a diagonal line through it. If I go into the sim card manager and select mobile data the phone shows 'Giff gaff' and my number below it but then immediately goes back to saying 'unknown'

Thanks in advance

It's a long-shot but what the heck?

With the SIM in the phone, go to Settings -> Backup & reset -> Network settings reset. You will have to reenter your Wi-Fi passwords and re-pair any Bluetooth devices afterwards.

Is phone sim locked?


If not then you can change the apn to that of your carrier
