Xiaomi Redmi Note 4X 64Gb + 4Gb Reviews

Evaluation 4
Advantages: In general, that's all. Fast, not bad looking, battery (with the right settings), memory, a good camera for this price.
Disadvantages: The sensor is sensitive, but on the rare 4 sensitivity is higher (here personal preferences, it's only in comparison), for me it is a small minus, the rest is in the comments
Comment: You can take it, especially if you take 12,000 from the Chinese, the battery is fine, the camera for this price is fine, it is only advisable to smoke a topic with 4 pda, at least deal with settings who have not dealt with miui before, in general With all my meticulous criticality to technology, I definitely recommend it.
Yes - the most important thing is that the processor comes with MTK (outdated Chinese) and Snapdragon (American), choose the second one, see the characteristics before, they are very different in work, despite the fact that there are 10 cores on MTK - they work worse, look first information on this topic.
Just in case, the MI a1 model is now on sale, everything is the same, but the camera and the speakers are better, pure android, in general, you should first compare before buying. And one more thing, until I figured out what was wrong, but with the transition to this model, problems began in Skype, namely, when headphones were connected, the interlocutors heard terrible distortions, changed headphones / Skype version and even installed the firmware from eu, the reason has not yet been determined
PS I picked up the same version of Skype with w3bsit3-dns.com, it seems that there were no bugs through the headphones, I also ordered a tester, I received it - I measured the battery capacity 2 times - 3820 showed, I think 4100 is like 180 km / h on the Zhiguli speedometer , although I relied on 4000 mache

Advantages: ⭐️ Divine finger response (see comment 1️⃣)
⭐️ Great screen
⭐️ Memory size (both built-in and operational)
⭐️ Battery
⭐️ Performance
✔️ Price
✔️ Slot for microSD (but here and minus - a joint connector with a 2nd SIM card, you can not use together)
✔️ There is support for fast charging
✔️ Additional features from xiaomi
Disadvantages: ❌ No NFC (very sad without it)
❌ Completion without headphones: (
❗️ Two speaker sockets, in fact one. Made for beauty.
❗️ When calling the numbers to 8 and +7, sees them different, that is, if you have a contact recorded at 8, then when you call it, it will determine +7 and will not see your contact. - It is being treated, there is an application in the play market
❗️ Acquired in white, and yet regretted.
❗️ Glasses on it are mostly inadequate in size (the size does not completely cover the front). There are normal, but they are not bad.
❗️ GPS is not always accurate (it can randomly radiate from 10 to 50 meters)
❗️ Mostly criticized by communication, but this is controversial and subjective
Comment: 1️⃣ The finger determines very well. When using, it happened to the top with feet, and in the rain or with moisture, and even dirty - I saw it, but it was mine. The response is very fast. But you need to get used to the rear location of the sensor.

Advantages: I took it from behind, because A number of applications (airbnb) are extremely slow on low-end models.
Everything is fine here: applications are flying, navigation is not stupid - in general, a good phone for work.
Disadvantages: The battery quickly sits down something, but didn’t go deep into it - it can somehow be set up.
Comment: Good, work phone for daily work.

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, which is installed on models with 32 GB of memory or redmi note 4. 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.
