You're probably not aware of this, but a Chinese company dubbed ProTruly has already released the world's first two "VR smartphones" with a built-in 360 camera last December. Don't worry if you missed the news, because chances are you'd be put off by the devices' sheer bulkiness, but according to Wuhan-based HT Optical, this may no longer be the case with the next release. At MWC Shanghai, I came across this company which appeared to be the 360 camera module supplier of ProTruly, as suggested by the presence of its two phones at the booth. The phones' brands were actually covered with tape, but given their distinct designs, the link between HT Optical and ProTruly was hardly a secret.
