There are many ways to transfer videos from Huawei Mate to computer. First,it has official tools. In addition, the more common
methods to transfer files to computer are USB, Bluetooth, Google Account, etc.
I have used all these methods, but I came across a
tool [mobikin.com] called Android Assistant, which can quickly help me connect my phone to computer and transfer files, the process is very fast and simple.You could have a try.
