After samsung s2, J7 and on8 and s7 moved to iphone10 for security , stability and design. Glad I moved to iPhone X. Using it for 4 hrs and slightly gets heat but no that bad then S7. FaceID is excellent feature. Go for it and really wroth spending for this phone.It has very good features like ios v11.1.1 operating system with 1.3GHZ apple A11 bionic hexa core processor, 3GB RAM and 64 gb internal memory.
