Ppl like me... LOL... I don't want hyper-super-bombastic SoC but failed to keep alive until 2PM everyday....

With Snap625 (and higher energy supply)..., I can crank up the screen brightness and can use the phone for many purposes (including Navi - the No. 1 battery killer....)  from 8AM till 11:59PM on the same day....But cannot say more as I have not tested any of the Snap625 myself...

But I am not gonna invest in Redmi 4... awaiting LeMoto P2 instead and after that can "throw away" all powerbanks and car charger

official in malaysia yet?

Just thought I'd mention after a few days of testing MIUI 8.1. Overall it is a beauty with new icons and colors to brighten up the system. Fixes and improvements can also be felt in many areas. But one thing I felt that overall snapiness of the system is somehow reduced by a bit. It is not as snappy as the previous MIUI 8.0 in my opinion...

contemplating to buy either redmi 4 prime or redmi note 3...

Yup bro 

exactly

not yet bro, I'm android noob lol

Just get the bootloader unlock as the main priority...

so i can update using fastboot method right..?
how to know if my device locked or unlocked?

Redmi 4 prime on China stable rom. 4g all the time, super heavy usage includes playing clash royale, surf fb and lowyat, whatsapp half of the time

Nope, just follow the guides in miui forum. Will require some trial and error as not every method is workable.

Guys, does this look like the Redmi 4 Prime official global rom?

2. The SD card slot shares the same spot as SIM 2. I didn't know this. Having SD card is not really a deal breaker, since it there is 32 gb internal storage. But, yeah, heads up to all potential buyers.

tqvm.will try later when i get back home
