Notice unknown

I put 3 stars, but I could put one or five.
What I liked about this device is its aesthetics, low weight, and excellent screen. Unfortunately, I quickly found incomprehensible power failures and random operation of Bluetooth. So I returned for a quick refund as Amazon knows to do. I think P7 Huawei is a good device, but I came across an exception. That is why I give the note does not have much value. However cooled a bit, I ordered another model that gives me perfect satisfaction.
