I've got to say that on my limited time with the 6P (24 hours) I am somewhat disappointed.
Google Play store crashed about 15 times during setup. Random reboots a few times.
My biggest disappointment with the phone is the battery. I was so excited for the Doze feature and tried it out. 100% charge, no apps runningrunning. 7 hours later, sitting on table next to my bed? Battery at 53%.
Did a factory reset, since all tech support has you do this. During setup the Play Store crashed a bunch more times.
Called tech support. The woman on the phone knew nothing. Why would someone at Huawei Tech support ask me which Nexus phone I was calling about. Had to put me on hold to ask someone what to do every step.
Now I find out that for warranty support, if they decide to repair it, I have to send it to them and will be without a phone while they decide what is wrong. And now with Google Fi, I can't use another phone while waiting unless I have a spare Nexus 6 or newer laying around.
Maybe Huawei is not ready for the US market yet.
