1, suspected of pre-installed software, but Huawei's cell phone this pre-installed amount is a bit much, at least I bought 3 Huawei's cell phone, did not find a pre-installed storm video and landlord. Of course, different channels to get the phone pre-installed different, this is true.

2, first keep the screenshot, is the screenshot of these software, and then the phone factory a bit, if the reset still have these software, that the phone is a new machine, if there is no longer a part of the phone, that the phone is a return of the phone.

It is recommended to go with the screenshot to find the customer service to change the new machine.
