First, why should you change
  This is a telecommunications dog replacement story, the landlord has always been a mobile user, last year the unit implemented a mobile office, a mobile phone, a telecommunications number, including traffic and the group inside and outside the call package, this package is almost endless, Caused a sudden drop in my mobile number consumption, of course, this is a good thing, how much to save yourself a little money, but the allocation of the phone down is really a bit frustrating, red rice NOTE Telecom version, or low with 1gRAM, yes yes red rice NOTE1 Not 2 or 3 Although it is a dual card dual standby, you can insert the unit's telecommunications card and your own mobile card at the same time, but there are several disadvantages can not stand: one is the card, the configuration is low, plus the system is bloated, experience is not good; the other is heavy, 192g Inconvenient to carry, single-handedly holding for a long time is a little tired; the third is big, the screen is too large, 5.5 inches my little hand can not control; poor quality of the picture does not mention anything, the only advantage is that life can also .
Second, why change millet 4C mobile version
  There are several reasons for this, sort it by importance:
1, cheap, sufficient performance. The idle mobile phone at home is too much, there is currently a Nokia 1100, 5230, 5800, motorcycle mpx220, Huawei u8800 and u8800 +, glory 3c two, fruit 4s, Tianyu three times optical zoom candy bar phone, also There are two bad tricks (in a word, I will never buy again). For my light mobile users, spending a lot of money to buy a flagship is not necessary.
2, you can brush the entire Netcom, or 2.0, dual card dual standby, checked in the forum, can say, will not buy back.
3. Both cards are micro-sim cards. Why is this important? Because the landlord's mobile card has more than one card (specifically you can own Baidu, do not start), the temporary use of mobile phones do not have to change the card, a mobile phone flight mode, another mobile phone boot like. Several mobile cards have old large cards, micro-sim cards with large cards, but no nano-sim, if you go to the mobile office to replace new cards (including large cards, micro cards, and nano cards), then copy Other sim cards fail. The unit's telecommunications card is also micro-sim, and now the new mobile phone, to find two micro-sim, performance and price ratio is not bad, or relatively small.
4, light weight, small screen, suitable for one-handed holding. This is not much to expand, the landlord felt his hand was small, try the single-handed operation of the screen is also the largest 5 inches.
Based on the above reasons, coupled with Aunt Zhang's successive push of the No. 1 shop's Xiaomi 4c, we started with the purchase link. At present, there are goods in East China.
Third, how to use the mobile version of Xiaomi 4c
1. Is there a difference between the mobile contract version and the entire Netcom version?
 There are, first, there is a difference in the box, the sticker is written on the mobile phone 4c mobile 4G contract version; Second, the network supports mobile 234G, China Unicom 2G, does not support telecommunications cards; Third, the system is different, there are a lot of mobile custom software . In fact, all hardware parameters are no different.
  Â
Out of the box
How does it feel to start?
  As the title says, small and exquisite, one-handed holding is very good, I feel very good, than a silly red rice note is really a heaven and earth.
3, how to experience the system, the card is not card?
  The mobile version is a 2G RAM. The program attached to the original machine is deleted. It has installed 25 various programs and has a bootable RAM of around 800-900M. The operation is very smooth, no card, and there is no problem with multi-task switching.
4. Can't expand the Micro-SD card 16GROM enough?
  16G available more than 12G hand available, enough to look at personal habits and needs, the landlord will also use the phone, WeChat, QQ, news reading, navigation, photographing, do not play games do not watch video, and occasionally use Netease cloud songs, installed The above software is available with 8.43G. There are no photos or anything on the phone, and if anything, I basically delete it once a month. This capacity is enough for my needs and usage habits, and it may be a bit tight under extreme conditions.
5, mobile contract version can brush Netcom?
  Yes, many people have succeeded and the landlord has succeeded. Â
Telecom 4G success 6. How about edge touch function?
  The function is relatively tasteless, useful, and sometimes useless, the sensitivity is not high, try a few times no interest, and off.
7. How about signal and battery life?
  The call is fairly clear, and it is not different from other mobile phones; the wireless network signal is stronger, and the same location is better than the red rice note, reaching the level of Huawei glory 3c. Battery life, the charging is really fast, fast charging is still effective; office workers use lightly, hung qq or WeChat, and occasionally take a look at the news, playing is worth buying, know almost, no problem filling a day.
  Â
8, other problems or disadvantages?
 Some people mentioned the problem of light leakage at the top of the screen. My machine did not; the screen touch has not found any insensitivity; the vibration prompt is indeed a bit slight; advertising push, I feel more refreshing than the red rice note after the brush; type-c The interface is a problem, a bit of a hassle. At present, it has not been fully promoted. It has already bought several adapters at Ma Yunjia. Camera, after all, the little prince, the original price of 1299 machines, than the current 600-900 price range of thousand yuan machine is still an advantage, the focus speed is not bad, defeated red rice NOTE no problem, close to or reach fruit 5s level. (Apple 7 out, I have 5s used, some understand?)
Fourth, how to brush the entire network of mobile contract version?
  Some friends said they wanted to unlock the BL. Some said that they could be strong brushes, and some said that they would follow the last one if they had a direct line brush after the Qing Dynasty or Sanqing Dynasty. Proceed as follows:
1, the mobile phone is full of electricity, my arrival is only 7% of the electricity, the No. 1 shop can tell me why? I vaguely guessed something.
2. Press the volume button and the power button at the same time, press and hold to enter the recovery mode.
3, select the clear data column, you can Sanqing or Siqing.
4, computer download millet mobile assistant, install.
5. At the same time press the volume key and the power button to enter the line brush mode.
6, mobile phone connection to the computer, select the brush package, I use the stable version.
7. Wait a long time until the end of the brush.
8, insert the telecommunication card test whether successful brush Netcom.
The picture is quoted from the network, and there is no picture taken when the user flashes. Here only the picture of the third step, the other is relatively simple.
Fifth, summary evaluation
  Compared with mobile phones with 5.5-inch screens, Xiaomi 4c appears to be small and exquisite. The size and thickness of the body can be controlled. The performance is sufficient. All aspects seem to be modest. The overall level is a little bit middle, if it is lighter than me. Users, can accept a small amount of memory and memory, a little hands-on ability to brush machine, then 699's mobile version of 4c is still very worthwhile to start.
