Got my Redmi Note 4 delivered on Monday.
Not a great experience with Geekbuying unfortunately.
I originally ordered a 4GB | 64GB version but then the order went to pre-sale due to warehouse stocking issues and they offered the 3GB | 32GB version. So I agreed but then that took nearly 3 weeks to just get despatched! Fortunately DHL delivered Monday after being sent on Friday.
First impressions are that it's great.
The speed with the Snapdragon is superb. I've always liked MIUI, used to flash variants on other phones, but I am using Nova for the launcher. Speakers are better than I expected. The battery is superb! I'm massively impressed by that.
Obviously negatives are the screen, colour wise and sharpness it's lacking. Camera is alright, as expected really. Coming from the S7 Edge it's not really fair to compare, but for the price they're good. Haven't used earphones yet so can't comment. Obviously I'd have preferred the 4GB version but I have really noticed any slowdown from switching between lots of apps just yet.
