Personally...after Samsung or Apple I would not go near Huawei....why use something like that made in China with inferior tech.
I had one of their blackberry clones at some point. It was a fine phone. I do worry about the potential for back doors, more so from unsubstantiated fears that have been floated on the media, than any real provable concern. Still doesn't give me standing to go willy nilly on blanket bans for the company because I dislike their market cap or their telecom infrastructure.
