We would like to thank our partners from the Chinese VNN team for helping us obtain this unit for review.

China’s Hatsune Miku fanbase has seen a surprising growth of attention over the years from various companies. These include companies such as SEGA, Sony, SCLA, and now more recently, Xiaomi. Xiaomi is ranked as one of the top manufacturers of smartphones in the world in terms of sales, despite selling almost exclusively in China. This is owed in thanks to China’s large population, and Xiaomi has seen Hatsune Miku’s untapped potential in the Chinese smartphone market.

Enter the Xiaomi Redmi Note 4X, Hatsune Miku edition.

Xiaomi released the Redmi Note 4X series as a special “celebrity edition” of the Redmi Note 4. Each color represents a different celebrity, and Hatsune Miku was chosen to represent the color “Blue/Light Green”. The special edition packaging of the Hatsune Miku Redmi Note 4X offered extra bonuses, which included a power bank, soft touch case, and a special serial number printed on the back, all packaged in a specially designed box.

The first flash sale started on Valentine’s day, and reportedly sold out within 2 minutes of the sale going live. 2 more flash sales followed, again all selling out within a couple minutes each. That’s multiple thousands of units sold in mere minutes… Flash sales in China truly are scary!

The special edition package sold for the USD equivalent of $190, while the regular edition retails for an even more affordable $150. Both packages include a phone of the same specifications, sans the extra bonuses and serial number for the normal edition model.

 

We were able to obtain the special edition model, which we’ll showcase and review below. But before that, let’s look at what the phone has to offer for the price.

Features

  • Metal-body phone measuring 151 x 76 x 8.5 mm, 165g weight
  • MIUI 8.0 (Android 6.0.1)
  • 5.5″ 1080p IPS LCD Display
  • 3GB RAM, 32GB ROM
  • Dual SIM (NanoSIM/MicroSIM hybrid tray)
  • MicroSD Expansion (via hybrid tray)
  • Snapdragon 625 SoC, Adreno 506 GPU
  • 13MP Rear Camera, f2.0, Phase Detect Autofocus, Dual-tone flash
  • 5MP Front Camera, f2.0
  • Rear Fingerprint Reader
  • 4100mAh battery
  • IR Blaster

Special Edition Exclusive Bonuses

  • 10,000mAh Power Bank w/ Hatsune Miku Silhouette
  • Soft-touch Plastic Case w/ Hatsune Miku Art by iXima
  • Unique serial number printed on phone below Hatsune Miku (初音未來) logo
  • Card with QR Code for downloading special Hatsune Miku theme

Main Drawbacks

  • No quick charge support
  • Limited network support outside of China (Max speeds of HSPA+ (3.5G) in the U.S.)
  • No advertised scratch resistance (get a screen protector!)
  • Not running latest Android version (Yet)

Packaging & Hardware

The packaging of the special edition phone is quite large, as seen with my Hatsune Miku nendoroid for scale reference. Measuring 31 x 19.5cm, it’s quite a bit heftier than most phone boxes. But this is because of what’s found inside…

The packaging slides open from the middle to reveal a turquoise-colored inner box. Nifty! Now let’s open it by lifting from that bottom left corner…

My eyes are immediately bombarded with various hues of blue and green. The large portable battery can be seen on the left, the phone itself in the middle, and the case on the right.

A closer look to appreciate Xiaomi’s beautiful packaging of this phone and its accessories.

The power bank has that nice cold metallic feel when pulling it out of the packaging. Quality! The pack is rated at 10,000 mAh capacity, which is enough to fill the phone’s already large battery 2.5X. It has only one USB port, however, so don’t expect to charge multiple devices at once.

 

The phone case is made of a coated, hard plastic, giving it that smooth “soft-touch” feeling. It unfortunately seems to stain or scratch somewhat easily, despite taking gentle care. While it looks nice, don’t expect the case to stay that way if you set it down on rough surfaces, or keep it in your pocket with other objects. Underneath the power bank is a special card with a QR code, allowing you to download the special Hatsune Miku theme. The QR code only works on Redmi Note 4X devices, however!

 

Pulling out the phone itself, it has a premium feeling that one would not expect from a sub-$200 device. With that much metal, you would almost think you were handling a flagship phone… A matte-finish screen protector comes pre-applied to the white border display panel, which you can keep until you get your own set of protectors (highly recommended, as it reduces screen visibility greatly).

The volume rocker and power button are located on the right side of the device, and on the back you’ll find a bunch of factory stickers placed below the fingerprint reader and camera. The bottom white sticker is also covering the special edition serial number, so let’s get rid of that…

 

There, that looks better. I also took the liberty of applying a tempered glass protector. Be careful which ones you buy, most promise they’re compatible with the Note 4X, but are not properly sized. We picked up a set from Amazon, which was a good value, and highly recommended: http://a.co/cTJ1n6y

 

With the stickers removed, the phone’s special print number is revealed. Sadly no “39” on this one! The last item you’ll find in the package is a small white box containing a 5V/2A (10 Watt) charger, and a SIM tray ejection tool. Should you ever lose this tool, you can also use a thin paperclip. The tray can use either two SIM cards (one Micro and one Nano SIM), or one Micro SIM and one MicroSD card.

Software

The phone comes with Xiaomi’s MIUI 8.0 software, which basically features their own customizations on top of Android 6.0.1. MIUI ditches the app drawer found on most other phone’s skins, but this is typical of phones in the Chinese market.

The special edition version of the phone comes with the Chinese version firmware installed by default, and I faced some challenges flashing it to the global version ROM, but eventually had success without needing to unlock the bootloader! If you purchase the normal edition from various sources, it’s likely to already come with the global version firmware pre-installed, but this isn’t always the case. We’ll link a source for the regular edition Hatsune Miku Redmi Note 4X at the end of this review!

 

Installing the Hatsune Miku theme on the Note 4X’s global firmware is normally not possible, but thankfully it can be done by first registering a Xiaomi Theme Designer account. After that, you can install the theme’s zip file as a 3rd party theme (link at end of review). The result is a simply adorable user interface with artwork by iXima. The home screen, lock screen, dialer, system prompts and even charging screens are all skinned. As for the ringtone… We’ll leave that one as a surprise!

Performance, Features & Battery Life

Comparing to my usual daily driver, a Sony Xperia Z3 Compact (high-end phone from 2014), I was pleasantly surprised with the performance of the Redmi Note 4X. The Snapdragon 625 is an 8-core processor built on an efficient 14nm process. Coupled with 3GB of memory (1GB more than my Z3 compact), the phone showed no signs of slowdowns, and was able to keep most tasks running in memory without needing to reload. It also stayed very cool and never got more than moderately warm.

The network bands of the phone are fairly limited, especially when it comes to LTE bands (only 1, 3, 5, 7, 38, 39, 40, 41 supported). At best, you can expect limited HSPA+ (3.5G) support from GSM carriers in the U.S., like AT&T and T-Mobile (personally tested on T-Mobile, and works fine). To see if it works on your carrier in your country, check using this site: http://willmyphonework.net/

The phone handled photoshooting about as well as you’d expect from a midrange phone, and the phase-detect autofocus made focusing for shots a snap. Just don’t expect too much in low-light conditions.

The fingerprint reader was easy to set up, and responds to touch in under a second. It’s “always on”, and can be used to unlock the device even from sleep. You can also use it as a wake button (when no finger print is registered), or as shutter button when shooting selfies.

Battery life was phenomenal, and I’d often end two days of moderate use with over 1/3 of the battery left. Heavy users can easily squeeze out two days of battery, which is great, considering the phone does not support quick charge for its massive 4100mAh battery. It takes about half an hour to get from 0% to 25%, or nearly 3 hours for 100%.

Where Can I Buy One?

Should you decide to seek the special edition for yourself, you’re on your own. Remember that all three flash sales sold out in minutes, and finding one will be difficult, and likely expensive. Flashing the ROM to the global version was also a tricky and dangerous task.

Luckily, we found a shop selling the regular edition in healthy quantities! It also comes with the global version firmware pre-installed, making setup extremely easy. You still get the light-green colored phone in a Miku-decorated box, but that’s pretty much it. It’s priced at $163, not including shipping.

    I bought a RN4 (MTK ver) before knowing there’s a Miku version. I want the miku version! Either way I feel like I was destined with the phone as a miku fan! Weird but real coincidence

  • The Soulless
  • :D

    Tried to use the theme with miui launcher but cannot be applied because I don’t have an authorization from the official market. Any idea of how to get the theme in a non-xiaomi phone?

  • Ryozu

    Man, time for a new phone.

    Is there any information about support for Cardboard? Does it have the proper sensors and does it suffer from the sensor drift so many other phones suffer from?

  • jrharbort

    I am not certain about its compatibility with VR.

    Thanks! :3

    How did you get a special edition with the power bank? The seller I’m talking to says it’s not possible to send it with the power bank for “safety reasons.”

  • jrharbort

    My friends had to carry it to another country, then ship it from there via DHL.

  • Ryxendi

    I see. Unfortunately, it looks like the only way for me to get the special edition is without the power bank. Now I have a tough decision to make.

  • jrharbort

    Performance of the SD version is a little below that of the MTK version, but the battery endurance of the SD version is significantly higher due to the more efficient chipset. Both phones are good, depending on which you prefer.

  • Gabriele “nightwolf” Battizocc

    Where u buy the special edition?

  • GaMe PLaYeR

    Hi there, will the theme works on Note 4X with SD435? Thanks in advance..

  • jrharbort

    The regular Redmi 4 and 4X, the 5″ model? It should, yes.

  • jrharbort

    From Xiaomi in China, thanks to help from friends.

  • William

    How exactly do you install the Hatsune Miku theme? Xiaomi Theme Designer? You mean Xiaomi Theme Creator app on Google PlayStore? Like how is that going to help install the theme which is still inside my dropbox account? o_O

  • William

    Haha, nice, for some reason my Redmi Note 4x(32GB/3GB) Hatsune Miku normal packing version doesn’t support the theme and here is the message after I tried to apply it as follow:

    “Themes from third-party sources are not supported error; download/auth rejected 402”

    I opened the Xiaomi Theme app> My account >Themes> Import> Pressed Ok and then the theme is now within the Theme app like as if it were there to begin with and now I cannot apply it at all….

  • jrharbort

    We explained in the article that you simply need to register for a Theme Designer account in order to be able to apply the theme, and provided a link for where to do it.

  • jrharbort

    I recently discovered Xiaomi has restricted installation of 3rd party themes even for theme developer accounts. You now have to use an app to install the theme, I recommend MIUI Theme Editor: https://play.google.com/store/apps/details?id=com.mixapplications.miuithemeeditor&pageId=100761263401613947903

  • Lintang Ws

    I can’t use that theme on rom global , i have log in xiaomi theme designer ..

  • jrharbort

    Check my response to William here in the comments. Xiaomi made some recent changes.

  • Lintang Ws

    It’s working , thank you so much 😁😁👍👍👍👍

  • Max

    China’s phone has bad quality though

  • Lintang Ws

    What keyboard on the original redmi note 4x miku edition used ? Gboard or swiftkey or other ?

  • jrharbort

    With the global firmware, the default is Gboard.

  • jrharbort

    An opinion, really. That’s a very broad statement to make.

  • Lintang Ws

    Okay thanks

  • Ronald Cheng

    William here.
    Thanks. Well, it actually worked on my Note 4X even before you reply. But now it doesn’t work on my Note 2, so I installed MIUI Theme Editor and guess what, it works on different Redmi devices too! 😀
