Currently holding a slowly lagging to death Note 3 so here I am asking now for advice:

1. Brand: As long as it's not Samsung, China Brand Phone (No offence Oneplus)

2. Budget: (New) Under RM2000/(Used) Under RM1500

3. Specs:
- 2/3 GB RAM
- 5 to 6 inch screen (Got too used to big screen phone)
- Lollipop with future update to Marshmallow
- MicroSD Card support
- Over 16GB Internal Storage
- LTE, NFC must
- Large Battery Capacity

4. What you need in the phone:
- Near pure stock android (if pure stock also ok)
- Can handle heavy use of browsing and media usage in a day
- Can be use over 2 years or so without performance hit (unlike ahem ahem Samsung ahem ahem)
- Doesn't get easily damaged by light knock
- Quick Charging, Wireless Charging, Waterproof can be optional

Also, since I'm changing phone, should I just sell my Note 3, swap if possible, trade in or just hands me down??

I guess that's all for now, would edit if necessary.

Thing is most were either outdated and focused on touchwiz which I'm starting to hate. That makes rooting my Note 3 even more useless if there's not enough rom options. So I hope that getting a new phone away from samsung could at least last more longer than samsung itself

Yeah that and the UI and the bloatware I had to endure. Also it already show signs after half a year of usage.

OPO -- need invite until OP2 came out, would consider but that would be last resort, along with LG G3 and nexus 6.
Nexus 5x and 6p -- Waiting for announcement right now.
