The Find X5 inherits most of its features from Oppo's flagship Find X5 Pro smartphone, but costs considerably less. While you'll have to invest around 1000 Euros (US$ 1,130), you'll be rewarded with a very strong high-end bundle overall.

Nice comprehensive review. Btw did I see you writing that ram the 8 gb can be increased to +5 so you actually get 13 gb! Only works if you have space left over on the internal 256 gb.
