Are folks really going to put a Chinese designed and owned phone in to their hands? Yes, all phones (for the most part) are made in China, but under direction and oversight of companies in more trustworthy nations. You had better believe that there are backdoors for the Chinese government.
Ok Charles.rogan , your just silly.... Samsung is KOREAN, south Korean but an Asian country no less.... Every Apple product is made in china.... they may be designed in the usa, but the brains that make it work come from China EVEN there designers are mostly Chinese ... Look it up.....
I'd be more worried about things like (Google them)
"Credit firm Equifax says 143m Americans' social security numbers exposed in hack"
"Yahoo says all three billion accounts hacked in 2013 data theft"
"Five million Danish ID numbers and healhtcare data sent to Chinese firm and Chinese Embassy by mistake"
I'm not afraid that a Chinese mobile manufacturer steals my data. I'm lot more worried that services/national bureaus that are meant to have our data cannot protect it...
