Huawei Honor 7 actually quite good, metal build quality. 5.2" screen, with finger print sensor.
If you just don't mind of not having Micro SD slot and 4G, Xiaomi Mi4 (not Mi4i) is also a good choice, 5" screen, cheapest and also very powerful with SD801 processor.

If you want some branded stuff, Sony Xperia Z2 actually is around that price range, very near to Oneplus X, 5.2" screen.

A little upper end, maybe you can consider the HTC One M8 Eye, metal body, 5" screen.

There's a couple of phones I'd recommend.

First of all, the OnePlus X is a really good choice. You really can't go wrong with this device. It's got a beautiful build, a decent camera, fast performance and a great display. On top of that, microSD and dual sim support makes it a complete package. Battery life isn't the greatest compared to some similarly priced options, but it makes up in every other department.

Next there's the Honor 7. There's not really much to add other than that it's a no nonsense phone that does just about everything you could want it to do, and pretty well too. The processor and GPU are slightly weaker compared to the OnePlus X, but battery life is much better and the metal build is less fragile. Also, fingerprint scanner.

Aside from that, there's the fantastic Xiaomi Mi4C. The Mi4C is like the anti-OnePlus X. The plastic build is lightweight and solid, and the phone is incredibly fast. Camera performance is impressive across the board, the display is very nice, the design is inoffensive and dual sim support. The only problems with the Mi4C are the lack of a microSD card support and the fact that the Mi4C is currently AP only. If there were local sets, I'd always recommend the Mi4C over the OPX, though that's just my opinion.

F1... whether u can bear the ColorOS UI or not

but i recommend , keep note 3 and buy OPX

i kept my Nexus 5 and take OPX for my 2ndary phone usage

How's oneplus two? I've been thinking about getting it to replace my old note. Also I don't see any active oneplus two thread, only oneplus X and oneplus one, so this kinda worries me a little bit

Nice. Actually I'm kinda in a dilemma, not sure whether if I should buy it right away or wait for oneplus three. Also even if OP3 comes out, I'd still have to wait a couple of months until the invitation period is over.

Please reccomend:-

1. Brand: Any
2. Budget: below 2k
3. What you need in the phone: Normal usage and camera, removable battery

thanks, any other options?

One Plus 2. But quite alot of bad comment. So I recommend G4 over One Plus 2.
