thanks ....
i think my partner get them huawei XXX that cost rm 300++ each

Huawei Mate 8?...too big as it 6 inch rite? I think same goes to Nexus 6P, but i love nexus range. How much u sell used Nexus 6p?

Which phone in the market now does offer dual micro sim card & 1 microSD ? the middle end range like RM700 to RM1.2k ...

Looking to buy a phone by next week, done a bit of research but I would like some of your suggestions Also bonus points if can buy in Digital Mall, Sunway or DirectD (not online, the highway outlet)!
1.Brand - Prefer NOT to have Samsung(hate UI and popularity  ),Oppo(depends lah, never heard Oppo's name in any review site so idk, good or not?)

2.Budget - around rm500-RM1000 (maaaybe can go up to 1200 but only if REALLY worth)

3. Specs - screen at least 5" or higher, Marshmellow, lesser plastic the better, I donno anything  about connectivity stuff, as long as can use Maxis postpaid plan, is good

4.What I need in the phone -As close to Stock Android as possible (if more customizable then ok, but annoying things like no app drawer is dealbreaker) Smooth and snappy performance, good camera, decent battery life, premium feel, can last at least more than 2 years
So far I REALLY like the OnePlus X, only thing stopping me from buying is OnePlus brand not very common in Malaysia so if got problem might be harder to fix, Honor 5X looks nice also but is not smooth and EMUI is  , Zenfone 2 is ok but my old phone was also Zenfone5.

Fast replay is super appreciated, thanks !
