I'm using the redmi note 4 (4gb ram and 64gb memory), global version, for 2 weeks and I'm very happy with it. The battery is great lasting 1,5 days. The 625 processor is fine (I'm not a game player, using it more for emails and watch Netflix), using 2 sim cards, I'm using the blackberry launcher. No nougat so far but not feeling the need. My other phone is a Samsung S7 which battery is a pain. I do not compare both devices as Samsung has a better processor and much better camera. But for the xiaomi price and normal use, I believe it's hard to find a better ratio price-quality. At the end of the day all we want is a phone that lasts full day and works well.
