Just got my Redmi Note 3 3GB Ram version today, I'll be doing comparison with my Huawei Mate 8

Design:
The design is very very identical and similar to the Mate 8, maybe its because of where the fingerpring sensor was placed and both is made from the same materials, however the RN3 back is much more slippery.

Screen:
This is entirely up to user preferance, the RN3 provides a more "white" and "bright" display, however the Mate 8 provides a more "warm" color and "yellowish" look. In clarity wise, they're barely noticeable as well, and I would say RN3 looked more natural , and Mate 8 looked more vibrant.

OS:
With the MIUI, its literally the same thing as EMUI found in the Huawei Mate 8, I would say these 2 phones are the most identical phone I've ever seen so far from 2 different company. However the only difference in OS is the placing of settings, animation, and many minor stuffs.

Speed&Smoothness:
As both of the phone are very very identical, I can barely tell the difference in smoothness, but Mate 8 is noticeably faster in every task, I think its due to the Kirin 950 chip compared to the MTK chip. However animation flows and smoothness are about the same and I can't tell the difference.

Camera:
Surprisingly for the price, the RN3 camera was able to match my Mate 8 and has better autofocus than my Mate 8, but in general like colors and vibrant, Mate 8 is still better, however in terms of details, I can't tell much difference as I'm no camera expert

Speaker:
Mate 8 all the way! The RN3 speaker quality is way far from the Mate 8, in terms of volume, clarity, and even bass! I guess this is one of the drawbacks for the low pricing.

Fingerprint scanner:
Both provides a very good spot for you to unlock your phone through fingerprint, the RN3 is slightly easier to unlock due to the fact that its a smaller phone compared to the Mate 8, however in terms of unlock speed, Mate 8 wins just by a tad of milli seconds, maybe like 0.3-0.5 seconds? Not really a drawback as its not that noticeable anyway.

Fast Charging:
For some reason, my RN3 doesn't support fast charging, search that up and some said it support and some said it doesn't, anyway from a normal consumer view, this is a drawback for me as there's no fast charging as default.

So in conclusion is that, if you want a cheaper alternative to other phones out there, this is a good phone as it has a good fingerpring scanner, good camera, smooth OS, and its just slightly behind the Mate 8. It kind of makes the Mate 8 unworth as so much price gap, yet so little difference.

Very small difference though, RN3 managed to put up a good fight, will comment on the battery life tomorrow!

It cannot be compared, because Kirin 950 even beat SD820 in almost every way in benchmark. However real life experience will have a very minor difference.

Smoothness is no longer a huge difference in this generation phone. I've used Note 5, Mate 8, and now Redmi Note 3, their smoothness are about the same, I think you're talking about speed as my Mate 8 is fastest between all these 3 phones.

Hey guys, my RN3 seems to have some random ads popup on the homescreen. I even rooted and delete all the unnecessary bloatwares, but its still there, any idea what's causing this? Thanks

MTK version can flash Global Rom?

I see, but I've deactivated all launcher other than Nova

Stock I guess

I don't think its the processor issue, I think its more to how heavy the bloatwares and UI is. Even in today's standard, Nexus 4 can perform simple tasks smoothly due to the light UI and pure android. I believe if you change to ROM's like CM or something similar, the performance will be much better.

Can't seem to find global rom for MTK version, does it exists?

My dad was in China and he bought it there, no Gapps and lots of bloatwares. Even stuff like apps auto download to your phone, super annoying!
