Android Device Manager.

I have ADM on my phone and it works really well for "Find my phone". I installed on my wife's phone and it only gives it's position to within 1200 metres, not a lot of use. Can anybody tell me why this is?

I'd guess that you have sat nav type stuff active on yours whereas hers is relying on the Network positioning accuracy ? But I may be wrong.

Thanks Old Geezer, I'll have to check her phone.
