At first, second and third glance, ZTE's latest flagship model, Grand X In, looks identical to the Grand X we tested a few months ago. With minimal external differences, the large Intel logo on the back is the only thing that "jumps" at you. Since this is the first smartphone based on Intel's (x86) platform that we've tested, many questions have arisen. Will there be limitations as far as application installation, compatibility etc. are concerned? How about unexpected bugs or issues? What to expect in terms of performance and battery autonomy? And heating?
