Let's see what everyone says. Summary of Xiaomi 4c Forum Issues.

IT 168 Evaluation Just last month, Xiaomi launched the long-rumored Xiaomi 4c smartphone. The machine is upgraded based on the overseas version of Xiaomi 4 I. While maintaining the 5-inch gold size, it is equipped with a high-end Opteron 808 processor, supplemented by new functions such as Type C USB interface, Full Netcom 2.0, and high-speed rail mode. Most importantly, the price of this machine is only 1.299 yuan (1.6 GB standard version), which is unique among smart phones with the same level of configuration, which also makes Xiaomi 4c another hot-selling model under Xiaomi's mobile phone. Xiaomi officially and confidently played the title of "Little Prince of Android".

However, as the saying goes, "the gun hits the first bird, and there are many people who are red." . Xiaomi 4c with high cost performance has indeed suffered a lot of controversy, mainly for two reasons: on the one hand, it may be that Xiaomi 4c just adapted to MIUI 7 does have more or less problems in stability; On the other hand, in the face of competition from other Internet mobile phone brands, Xiaomi 4c will inevitably be maliciously slandered by some water forces. In this regard, the author specially sorted out the common problems in the Xiaomi 4c forum, and tried to use the Xiaomi 4c tester in his hand to test them one by one, in order to find out the root of the problem to the maximum extent and provide some reference for everyone to buy this mobile phone. (The picture in the article comes from the Internet)

1. What is the main frequency of the Xiaolong 808 processor used by Xiaomi 4c?

Faced with the high cost performance of Xiaomi 4c, many netizens have raised such questions. Here, the author would like to explain that Xiaomi 4c uses a 64-bit Snapdragon 808 six-core processor, and the highest frequency of a single core is 1.8GHz, while Xiaolong 808 processor uses two A57 cores and four A53 cores. According to the author's actual measurement, the A57 core frequency of Xiaomi 4c is 1.8GHz, with four A53 cores, and the single core frequency is maintained at 1.4GHz.

2. Does the full netcom 2.0 technology adopted by Xiaomi 4c support dual telecom cards and dual 4G?

Some netizens mentioned that Xiaomi 4c is loaded with two 4G cards at the same time. Can it be used normally (standby) at the same time? In this regard, Xiaomi officially explained that two telecom cards were put in at the same time and could not stand by at the same time. In this regard, the author wants to say that this is a * * * problem encountered by mobile phones at present, which is caused by the technical characteristics of CDMA and has no solution for the time being. However, except for two telecom cards, China Mobile, China Unicom and China Telecom can be paired at will (Mobile Mobile, China Unicom, China Unicom and China Unicom), and they can set up their own Internet access, regardless of card 1 and card 2.

3. Does Xiaomi 4c's C adapter support data connection?

Some netizens mentioned in the forum that the Type C adapter they bought can only be charged and the data connection cannot be completed. In this regard, the author referred to the feedback from many users and conducted a field test, and found that he did not encounter what the netizen said. I believe this should be just an example, or it is caused by the use of unqualified data cables. Xiaomi 4c is equipped with the officially provided Type C USB adapter, which can realize both charging and data transmission.

It is worth mentioning that some netizens mentioned the issue of OTG switching, and the official of Xiaomi Forum also made a corresponding answer, saying that the OTG switching supporting Type C interface will be launched later, and users in need can pay attention to the relevant trends of Xiaomi Mall, or buy an OTG line with Type C interface in formal channels.

4. Why is the so-called edge touch technology insensitive to use?

Some users are not sensitive to feedback and the success rate is not high. In fact, most of them are caused by incorrect use methods. First, users need to upgrade their Xiaomi 4c to the latest miui7 version. Secondly, the effective sensing area of edge touch is within the red line below. According to the author's actual measurement, the success rate of double-clicking the upper edges (i.e. angular positions) of 4c's two side borders is over 90%. It is important to note here that not all the boundaries on both sides of 4c. In actual use, many users mistakenly tap the border of 4c with their fingers, resulting in a low success rate. At present, edge touch supports two operations: global return (you need to tap twice) and taking pictures (tap in advance, and a white round bright spot will appear on the screen, and then you can take pictures).

5. Three kings are not very sensitive (three touch buttons).

Some users reported that Xiaomi 4c's three donkey kong keys were insensitive to touch, especially after being placed horizontally, the click success rate was not high. According to the official statement of Xiaomi Forum, this is a bug of MIUI system, and the internal test version has solved this problem. Subsequent stable versions and development versions will release revisions in time, so it is good for everyone to update the system in time.

6. Why does Xiaomi 4c have a regular flashing screen?

Some users have reported that some areas of Xiaomi 4c screen will flash, but not all the time. After verification in many places, the author found that many users reported this problem after using Xiaomi 4c smart protective case. Therefore, the author guesses that this problem should be related to the compatibility of smart protective sleeve and should be solved in the later system update. It should be noted that Xiaomi 4c in my own hand has not encountered this problem, and the author has not used the official smart protective cover, so it is recommended that users with this problem take off the smart protective cover and try it. Of course, if you still have this problem after taking it off, which will affect your use, you can go to a nearby millet to replace it after sale. Some netizens have successfully replaced the problematic Xiaomi 4c.

7. Why is the battery life of Xiaomi 4c too short?

From the configuration point of view, Xiaomi 4c has a built-in battery with 3000+mAh capacity, and with a 5-inch 1080P display screen that consumes little power, the actual service life should be between 1 day and 2 days (the specific situation varies from person to person). In order to get better endurance performance, you can try the following operations: set the mobile phone to performance priority mode (setting-power and performance-performance priority), and turn off the edge touch and double-click wake-up function at the same time, which should obviously improve the endurance of the mobile phone.

8. Does Xiaomi 4c support dual communication?

Xiaomi 4c is a dual-card dual-standby mobile phone, but it does not support dual-call function, that is, two cards cannot answer incoming calls at the same time. From the author's personal point of view, the function of two-way call is not very practical. After all, it is rare to receive calls from two numbers at the same time. Just choose according to your own needs.

9. Is MIUI 7 pre-installed in Xiaomi 4c factory?

It should be noted that the factory pre-installed version of Xiaomi 4c is MIUI 6, which requires users to brush in the beta version of MIUI 7, and the official version of MIUI 7 will be launched soon. You can refer to the brushing tutorial and related resources here. Click to view details.

10. What are the purchasing channels of Xiaomi 4c at present? Do you need to increase the price?

In this regard, I believe many netizens have discovered that Xiaomi 4c is not as rich as the previously released Red Rice Note2. Of course, perhaps Xiaomi 4c is more popular with netizens. Anyway, Xiaomi 4c is still snapped up regularly in official website, and the specific delivery time should be 10: 00 every Friday morning. At the same time, Xiaomi's official offline store can also purchase the spot at the original price. I suggest you check the specific supply situation yourself. In addition, the current e-commerce channels include Tmall, JD.COM and Gome Suning. , there are different degrees of price increases, generally around 200 yuan, for your reference.

1 1. Is Xiaomi 4c worth buying?

I believe this is one of the biggest questions in the hearts of many netizens, and the author will also take the answer to this question as the summary of this article. From the configuration point of view, Xiaomi 4c is undoubtedly very valuable, especially equipped with the Opteron 808 processor only available in high-end models, which supports the dual-card dual-standby full netcom function. It is also equipped with the currently popular front and back pluggable Type C interface, and the camera is also equipped with a13 megapixel camera, which supports PDAF phase focusing function. . . These are the advantages of Xiaomi 4c. If you simply talk about configuration, the same price mobile phone is second to none.

When it comes to system experience, the advantage of Xiaomi 4c is more obvious, but because MIUI 7 is still unstable, this advantage has not really been brought into play. After all, MIUI, as a "veteran" in the domestic mobile phone system, has a benchmark performance in both the perfection of system functions and the integrity of the overall UI design. In the future, with the continuous improvement of MIUI 7 system, the whole machine experience of Xiaomi 4c will be greatly improved. On the whole, most of the minor problems encountered by Xiaomi 4c users are caused by system reasons or improper personal operation, which can be improved by upgrading the system and learning. Of course, the author is not saying that Xiaomi 4c has no hardware problems. After all, even the best mobile phone will have the concept of yield. So if you encounter such a small problem when using Xiaomi 4c, you can directly consult the local Xiaomi after-sales service. After years of accumulation, Xiaomi's official after-sales foundation and service quality are not the same.
