Hi all, I'm hoping one of you will Out-Nerd me here; Bit of a fun one today - I'm testing a failure case for a mobile phone where, when it loses network, it'll fail to reconnect. Problem is; I need to be able to control when and where it loses network in order to figure out exactly what it takes to cause the phone to entirely fail. I've tried a couple of basic things already, making up a foil lined box that happily killed all signal on my Smartphone (Xperia X) But the device just shrugged, stepped down to GSM and carried on without a care. Anyone have any further ideas on what I could do to completely cut this thing off from signal? I've even thrown this thing into a Microwave and it still doesn't give up on connecting. Any help would be appreciated.
