Xiaomi Redmi Note 4X 64Gb + 4Gb Reviews

Evaluation 5
Advantages: I forgot what it means to “not enough” memory, “the application is not going”, or the smartphone is “dead”. MTK Geliki is quite smart and works without any overheating in any modes and applications. With a large size is not bulky, both cameras give excellent quality photos and video. According to the price tag beats Samsonov and iPhone with a much lower performance. Yes, and the prices of components pleasantly pleased.
Disadvantages: It is more likely cavils and wishes.
1. Slippery. Corrected "diapers" on the back.
2. Glass is not a Gorilla Voice. Corrects invoice bulletproof glass.
3. There is no menu of applications and widgets, for me, as for the old Samsung player, rather, the disadvantage is that everything is dumped on desktops. Corrected by any launcher from the playmarket, they are there the sea.
4. Sound Although loud and clear, but in the films and songs some unnatural. Corrected software from the playmarket.
5. Kutsaya grade, not even the headphones. Thank God there is a needle (unlike the iPhone 6+, which my friend bought)
Comment: This model is a real "bomb" in the mobile phone market. Samsung and iPhone can relax with their exorbitant prices. Mimishka taxis !!!

Advantages: 1. Large, high-quality screen;
2. The presence of a fingerprint sensor;
3. The MIUI shell definitely leaves only positive impressions, everything works very quickly;
4. Large volume of the battery (with active use is enough from 9 am to 11-12 pm; full charge from 1% to 100% for 1 hour 25 minutes);
5. Perfectly catches the connection, there are no failures in LTE and WIFI
Disadvantages: 1. Lack of NFC;
2. The camera shoots badly, you need to try hard to avoid a blurry picture;
3. The phone gets very hot when using demanding applications (especially games) This is due to the fact that it has a MediaTek Helio X20 processor, not a Qualcomm Snapdragon 625 processor, which is installed on models with 32 GB of memory or redmi note 4. On Topical forums also write that the MediaTek Helio X20 processor eats the battery more than the Qualcomm Snapdragon 625, and the Qualcomm operating system updates come faster. In general, the obvious advantage of the processor based on Qualcomm. It is worth considering this fact when buying a phone.
Comment: I took this model instead of the stolen iphone 6s.I wanted to try a new shell after ios, plus a large screen diagonal. In general, the choice pleased. The only thing that really upset the quality of shooting a photo, generally keep quiet about the quality of the video after the iPhone. Of the main advantages - a large amount of battery, unlike the iPhone, which had to be charged 2 times a day. I advise you to look closely at the model based on the Qualcomm Snapdragon 625 processor!

Advantages: - a great memory.
- A lot of RAM.
- Many interesting features from xiaomi and miu firmware.
- The camera and screen at the proper level. Documents fotkat with a bang.) Everything is clearly visible. Focus works well.
- little heat
- optimal screen size
- holds charge well, charges quickly
This is the main advantage of the phone a lot more)
Disadvantages: Here, rather than the disadvantages of a niggle. Each of the above may not be a disadvantage, as it can be technically explained.
- from 4gb RAM available 2 - 2.5gb
- out of 64 gb 54 available
- there is no nfc chip, if it is important to someone
- Chinese manufacturer, so that all covers and glass only through the order.
- there are downsides to the firmware, such as the inability to remove some applications, but they do not particularly interfere.

And that's all, they are no more
Comment: The phone exceeded all expectations that were assigned to it. Comfortable, functional, capacious, stylish.
The phone is ideal for the description is very cheap and very cool.

The phone is taken from the reseller for 11990 + case + glass. The total cost is 13,200. You can find it cheaper, order it with Ali, for example, the price tag there will be about 12 tr.
If you have any questions, I will be happy to answer.)

Advantages: Memory. Powerful battery.
Disadvantages: Heavy and strives to slip out of hand.
Comment: All that I wanted from a smartphone I got in this model for a very reasonable price (11,000 rubles). Memory so much that insert another memory does not make sense. For me, above the roof. Screen size - for my phone is extremely large. Size will no longer be comfortable in hand. The most important requirement is the battery. I suffered from the old smartphones that had to be cut during the day with active use and at the right time I was left without communication more than once. With this phone with permanently on WiFi and Internet search, charging is enough from lifting to hanging up. If you do not use the Internet, it lasts for two working days. Probably for smartphones to date, more powerful batteries yet. And, if the screen were smaller, then the charge would be enough for more. But, I basically took the big screen. The only minus is the unusual gravity and shape, which contributes to the slip and it will slip out of my hands, but I am used to it and do not notice this shortcoming. In general, this is the first smartphone, which I am satisfied with all 99%.I even call him not just a telephone, but a car, because it is not just a telephone, but a real car for work and leisure. All in one.

Advantages: 1. Screen quality.
2. Design is stylish.
3. Camera quality is better than expected. For that kind of money is great.
Disadvantages: The big drawback, as it turned out later, when the phone reboots, the time zone setting flies and Moscow defaults.
The forums offer 5 different solutions, tried the simplest of the first 4, did not help. It remains only a flashing, but there is no desire to bother.
At the same time, the firmware is now official, global, stable.
As far as I understand the manufacturer, this has been known for a long time, the problem manifested itself in earlier models, and they are in no hurry to fix it. It's a shame.
Comment: In general, I like the phone very much, stylish, comfortable, smart for such money (11,690 rubles), despite the inconvenience with the time zone.

Evaluation 5
Advantages: Screen 5.5 is of course not for a small hand, but I am average and there are no problems with using it. There is a mode that reduces the screen as much as 3.5 inches for convenience. For the first time I am dealing with a shell, except for some letter jambs, everything is on the level. The battery is average, with active use, enough for a working day.
Disadvantages: The camera is not at all happy, maybe it hasn’t yet been set up, and maybe an update will come up that will fix everything, but it seemed worse than on my past Sony Xperia Z1.
Comment: I took for 11250, the phone justifies every ruble spent, I like it very much, I use it for a week, everything goes smoothly.

Evaluation 5
Advantages: - Price and performance.
- Great phone for the money.
- good build
- With the battery all the rules, despite the 2 SIM cards. Provided that Internet messengers and mail with bitrix and bracelet Band2 are always on
- Not heated
Disadvantages: - The camera is at least 13 megapixels, but in cloudy weather and in the evening the quality is not at all happy
Comment: Just for reference
If you charge 100% in the morning, then when you work on 2 sim and a bunch of applications in the background, plus the bluetooth is constantly turned on, through which the bracelet and gill are notified, then by the end of the day you will have 25%. The same will be if you listen to music online.

Advantages: 1. Price-price-price: for 12 thousand for 4 \ 64 memory and a smart processor - super!
2. MIUI Shell - I mastered it on the previous Mi5 device. Works perfect. In combination with 4GB of RAM, no application has ever crashed, although there are many open applications at the same time. Updated through the "three points" on the official version of Global 8.2.1.0
3. Battery (again, in conjunction with MIUI) - with very active use (music, mail, surfing, video) keeps the day stable (from 6 am until midnight). Powebank began to gather dust in a backpack
4. Assembly and material: after using Mi5 with a glass cover (broke), the choice fell on this phone, and not on Mi6. Solid material and well assembled.
5. Well and consistently catches 4G and Wi-Fi
Disadvantages: 1. Confusion in the name of the model and processor version: whether it is RM Note 4, or RM Note 4X. In the end, after flashing to 8.2.1.0 in the settings in the model name, 4X is lit. But (!) MTK processor (MediaTek Helio X20), then you need to install the firmware on the RM Note 4 MTK model. Then everything works stably. The same applies to accessories - on Ali you need to order for the RM Note 4 model. But now there are tips on how to distinguish one phone from another (by the location of the LED indicator)
2. Camera - if the phone wants to be used instead of the camera, then this is not the option. But I remind you about the price 
3. The fingerprint scanner is slightly slower than on the Mi5. Not critical, but noticed
4. Common for MIUI: In the shell, all installed applications are stored on the desktop (as in the iphone). Those. you have to manually push them into folders
Comment: The second phone from Xiaomi did not disappoint, despite the fact that it is not considered a flagship. The power of the processor and 4GB RAM give excellent results.I read somewhere that the battery quickly sits down and the phone heats up, but during the whole period of its use I have not come across it. Perhaps because I do not play games on the phone.
Despite the shortcomings described, I did not lower the overall assessment, since for me they are not critical.

Advantages: The minimalist design, metal and glass with small plastic inserts for the antenna in the style of the antenna, a nice shape with roundings to the back cover is comfortable and allows the thumb to reach the left side of the screen.
IPS display with good correct (neutral) colors, high brightness margin and adjustable contrast. Full Hd resolution is quite enough for 5.5 screens, the larger one is already redundant and eats battery. Here in this regard, all is well.
Powerful enough iron. Applications in the background keeps no brakes. In the shell, everything flies without a hint of scrapping. But with Blitz, the device coped worse than expected: the shadows should be turned off for a stable FPS 35+ (at medium settings with other effects other than shadows FPS around 55), the same result was on an old Lg G3 / Mali is probably the reason for the poor optimization.
Contrary to forecasts, the phone is not very hot. By wi-fi, heating is generally imperceptible, by 4g is already warm, but within the normal range.
The sound quality during a conversation is quite good with noise, it is clear that the work on the bugs after Xiaomi Redmi Note 3 Pro has been completed.
GPS and LTE sure, picks up quickly
The battery is capacious, for the day - for the eyes. Do not lie about the level of charge. At 1 fight in WOT Blitz spends 1-2%
Disadvantages: The shell does not implement some convenient function, such as a full block / unlock with a double tab, or a short-long press with a finger up / down mixing to scale the image.
Build quality: in my specimen I have a slit under the screen that has a slit through which the light from the backlighting of the keys breaks
When playing a sound at the time of adjusting the volume, distortion / noise occurs - a trifle, but unpleasant
The camera as a whole is not bad with fast HDR, but without optical stabilization and rather narrow in viewing angle.
Comment: The phone was bought after the experience of using several years by the "flagships" of LG and the year Xiaomi Redmi Note 3 Pro (alive, with my wife). With the current price of about 10K, the quality and filling of the phone is more than satisfied, ready to forgive minor defects.
