Hi guys!
A week ago I received a new smartphone from Xiaomi – Redmi Note 4X.
It sports the new Qualcomm 625 just like Xiaomi Redmi 4 Pro which about I already write a review.
So I can call it a bigger brother 
.
Now lets see the hardware:
Display: 5.5 inch FHD 2.5D Arc screen
CPU: Snapdragon 625 Octa Core 2.0GHz
GPU: Adreno 506
System: Android 6.0 ( MIUI 8.1 )
Camera: rear camera 13.0MP with AF and flashlight + front camera 5.0MP
Bluetooth: 4.2
Navigation: GPS, A-GPS, GLONASS
Sensor: Accelerometer, Ambient Light Sensor, Gravity Sensor, Gyroscope, Infrared, Proximity Sensor, Fingerprint Sensor
SIM Card: dual SIM dual standby, Micro SIM + Nano SIM cards
Network:
2G: GSM B2/3/5/8 CDMA 2000/1X BC0
3G: WCDMA B1/B2/B5/B8 TD-SCDMA B34/B39
4G: FDD-LTE B1/B3/B5/B7/B8 TD-LTEB38/B39/B40/B41(2555-2655MHz)
My unit sports 12 megapixels camera sensor from Sony but I see the other item where the camera from Samsung.
As I heard the Sony is a little bit better. But you can check the image samples and decide yourself.
Maybe you are confused why so many Redmi Note 4 versions?
Xiaomi makes different phones for different markets.
You remember my other review about Redmi Note 4 with MTK processor.
This one is with newest Snapdragon 625 and even it has a bit lower performance in Antutu test, it has better battery life!
Other visual difference I see in Redmi Note 4X is that bottom and top section of the phone are plastic.
Also the IR sensor is moved from the center to the left.
The display should be the same in MTK and Snapdragon version.
It’s 5.5″ IPS 2.5D and it’s very bright even in sunlight!
The phone came with installed NON official multi-language MIUI ROM.
But when I check the status of Boot loader it shows UNLOCKED on both phones that I bought.
This is really great for experienced users (like me ) because any ROM can be flashed and rooted
For the tests I installed official MIUI 8.2 stable Android 6 and official MIUI 8.3 beta Android 7.
But let see the test results:
Android 6 on the left, Android 7 on the right:

You can see that in Android 7 results are little better.
You can also check it in video here:
Now let check Benchmark scores.
Again Android 6 on the left, Android 7 on the right:

Now the difference in multi-core score is bigger!
The numbers are just numbers Lets check real gameplay on N.O.V.A. 3 as always
I cant feel any lag in game.
It runs smooth as it should it be!
The video is made with the new feature in MIUI called Screen recorder.
Very useful feature for me We also see that MIUI developers make new improvements to pleased people.
Now lets check the images I took.
As always you can click on the images to see them in full size:
You can see the camera make very nice images for a budget phone!
To conclude this review I can say that this Smartphone – Xiaomi Redmi Note 4X is really worth!
I upgraded my wife’s Redmi Note 3 Pro with this one
And I highly recommend it!
