My wife has a Huawei P7. Seems like it has the Broadcom chip :( Huawei has provided exactly 1 update to the phone since it was released. And only for those living in New Zealand. Other than clearing out all the trusted wifis and just keeping the home wifi, is there anything at all that can be done?
