I have a Huawei phone (Ascend P7), and I'm pretty happy with it.
If I were to be concerned, I'd be more worried about them fudging the performance data. As others posted, if you're worried about spying, don't own a mobile device.
I posted this before:
"I have a Huawei Ascend P7. It's miles better than my last phone (LG G2 mini). I find the build quality to be very good. I had it survive a very bad fall. The performance is decent, not as good as modern flagships, but an awesome price to performance ratio (I got it for 180 dollars, it goes for 250 unlocked these days).
They did do a Volkswagen-style cheat on the FutureMark benchmark:

so yes, they might be on the "sketchy" camp.
But I've found most of the premium stuff from China to be as good or better than equivalents from other countries, my girlfriend has a Lenovo phone and it's excellent too."
