Yeah! Lenovo Zuk z1 better than redmi note 3. Mostly people want good camera at this price and redmi note 3 gives 16mp and 5mp camera but believe me the redmi note 3 has worst camera of all Xiomi smartphone, but the Zuk Z1 prove itself best camera smartphone under 15, 000 INR but the Zuk z1 use old hardware like processor 2.5ghz quad core snapdragon 801 3gb ram where Redmi note 3 gives latest 1.5ghz hexa core snapdragon 650 2/3gb ram.
But it's note a big issue u can play high graphics game on high graphics smoothly. Zuk z1 gives 64gb internal memory and it lakes of external mmc, btw 64gb memory is enough for storage. Zuk z1 gives 13mp rare and 8mp front selfie camera it can captured more clarity than redmi note 3, zuk z1 can caputerd very good pictures also in low light.
So if u want good camera smartphone so go with zuk z1 or U want more gaming experience than go with Redmi note 3!
