如果你把盒子倒过来，你可以看到贴了几张贴纸。它们会告诉您智能手机的确切型号，以及IMEI或序列号等其他信息。然而，印在这些贴纸上的大多数其他细节都是中文的，所以除非你说这种语言，否则它们不是很有用。
打开包装盒，您可以看到小米红米 4A(Xiaomi Redmi 4A)智能手机坐在内纸托盘(paper tray)的顶部。
取出智能手机后，您可以查看一下随附的物品：电源适配器(power adapter)、USB 2.0数据线、保修卡(warranty card)、用户指南(user guide)和SIM 卡插入(SIM insertion)工具。不包括耳机，可能是因为它们会稍微提高智能手机的价格。
小米红米 4A(Xiaomi Redmi 4A)智能手机提供三种不同的颜色变化：金色、玫瑰(Rose Gold)金和深灰色(Dark Grey)。我们测试的模型是更清醒的一个，深灰色(Dark Gray)。
小米红米4A(Xiaomi Redmi 4A)拥有一块5.0英寸IPS液晶屏(IPS LCD screen)，分辨率为720 x 1280像素，像素密度为296 PPI 。(PPI pixel)您可以在本指南中阅读有关PPI及其含义的更多信息：什么是PPI，它是否重要？。不幸的是，没有康宁大猩猩玻璃(Corning Gorilla Glass)保护显示器。
这款智能手机由最高运行速度为 1.4GHz的四核Snapdragon 425处理器和运行速度为 500MHz 的(Snapdragon 425)Adreno 308图形单元提供动力。它适用于 2GB 的RAM，并提供 16GB 的内部闪存存储空间(flash storage space)。如果您需要更多存储容量(storage capacity)，可以使用辅助SIM 插槽(SIM slot)插入最大容量为 128GB 的 microSD 卡。
小米红米 4A(Xiaomi Redmi 4A)的后置摄像头具有 13 兆像素的传感器、f/2.2 的光圈、自动对焦，并受益于LED 闪光灯(LED flash)，可用于低光摄影。前置摄像头(front camera)有 5 兆像素和 f/2.2的光圈。
在连接性方面，小米红米 4A(Xiaomi Redmi 4A)支持 802.11 b/g/n wireless标准，但不支持 802.11ac。这意味着您只能使用它连接到 2.4GHz 无线网络。智能手机内部还有一个蓝牙 4.1(Bluetooth 4.1)芯片，用于将其连接到各种设备。

设计和建造质量
小米红米4A(Xiaomi Redmi 4A)设计经典，线条比前代更锐利。它是一款 5英寸屏幕(inch screen)的小型智能手机，也很轻，主要是因为它的机身是由聚碳酸酯制成的。乍一看，它看起来像身体是金属的，但外观具有误导性。
硬件按钮位于其传统位置：音量摇杆(volume rocker)和电源按钮(power button)均位于智能手机的左上角(left edge)。尽管它们没有不同的纹理，但您应该没有问题识别哪个是哪个，因为音量摇杆是由单件制成的，并且比(volume rocker)电源按钮(power button)长得多。
在左侧边缘(left edge)，有SIM 卡托盘(SIM tray)，您可以使用盒子上的别针或手头的任何回形针(paper clip)将其弹出。底部边缘是用于充电和数据传输的微型 USB 2.0端口，顶部边缘是红外端口和音频插孔的所在地。(micro USB 2.0)

在背面，靠近智能手机的底部，有扬声器格栅(speaker grille)和银色的MI 标志(MI logo)。
软件按钮都位于智能手机正面的显示屏下方。我们喜欢它们与屏幕分开的事实。但是，我们不喜欢它们的还有两点：一是它们没有背光，因此在夜间难以识别，二是它们的定位与标准的Android智能手机相反。从左到右，红米4A(Xiaomi Redmi 4A)有Apps、Home和Back。通常的顺序是Back、Home和Apps。它有效，但您必须适应这种安排。

Does this very affordаble smartphone offer a good user experіence? Let'ѕ find out, in this rеview:
What is the Xiaomi Redmi 4A smartphone good at?
The Xiaomi Redmi 4A is a great smartphone for:
- Fulfilling basic smartphone needs, such as browsing the web, running social media apps or taking a quick picture
- Keeping you connected to the world while not asking you to charge it every day, because its battery can last for two days in a row
- Giving it to your child or to someone elderly, as their first smartphone to use
- A great backup smartphone, in case your main one breaks or it remains without battery
Pros and cons
The Xiaomi Redmi 4A has quite a few good things to brag about:

- Signal reception could be better
- According to xiaomidevices.com, there's no official plan for upgrading to Android 7 Nougat
Verdict
The Xiaomi Redmi 4A is a bargain. It costs very little and offers all the basics you need. It doesn't impress with its hardware nor with its looks, but it manages to impress with its long lasting battery and with the good quality of its screen, camera and build. Xiaomi Redmi 4A is not for those who want speedy internet browsing sessions or high framerates in games. It is however, a great smartphone for those who are just meeting with the Android world and don't want to spend lots on it. It is also a great choice for your children and for your grandparents.
It could also be a good choice for your backup smartphone, to keep in your backpack while travelling or use it when your main one breaks. In the world of ultra budget smartphones, Xiaomi Redmi 4A might be the best choice you can make.
Hardware specifications and packaging
The Xiaomi Redmi 4A smartphone arrives in a small white box with a simple design. It is made from cardboard and it features a large 4A text engraved in white on its top. One of its sides holds a small MI logo and the other something written in Chinese.
If you turn the box upside down, you can see that there are a few stickers attached. They tell you the exact model of your smartphone, as well as other information such as the IMEI or serial numbers. Most of the other details printed on those stickers is in Chinese however, so unless you speak this language, they are not very useful.
Open the box and you can see the Xiaomi Redmi 4A smartphone sitting on top of an inner paper tray.
Once you take the smartphone out, you can take a look at what is bundled with it: a power adapter, a USB 2.0 cable, the warranty card, the user guide, and a SIM insertion tool. There are no headphones included, probably because they would have slightly increased the smartphone's price.
The Xiaomi Redmi 4A smartphone is available in three different color variations: Gold, Rose Gold, and Dark Grey. The model we tested was the more sober one, Dark Gray.
The Xiaomi Redmi 4A has a 5.0 inch IPS LCD screen with a resolution of 720 x 1280 pixels and 296 PPI pixel density. You can read more about PPI and what it means, in this guide: What is PPI and does it matter?. Unfortunately, there is no Corning Gorilla Glass protecting the display.
This smartphone is powered by a quad-core Snapdragon 425 processor running at a top speed of 1.4GHz and an Adreno 308 graphical unit running at 500MHz. It works with 2GB of RAM and offers an internal flash storage space of 16GB. If you need more storage capacity, you can use the secondary SIM slot to insert a microSD card with a maximum size of 128GB.
The rear camera on the Xiaomi Redmi 4A has a sensor of 13 megapixels, an aperture of f/2.2, autofocus, and benefits from a LED flash for low-light photography. The front camera has 5 megapixels and an aperture of f/2.2.
In terms of connectivity, Xiaomi Redmi 4A comes with support for the 802.11 b/g/n wireless standards but not 802.11ac. This means that you can use it connect only to 2.4GHz wireless networks. There is also a Bluetooth 4.1 chip inside the smartphone for connecting it to various devices.
The Xiaomi Redmi 4A is a Dual-SIM smartphone and it works in Dual SIM Dual Standby mode. When you have two SIM cards inserted, the smartphone supports 4G calls and data connections only on the primary SIM, while the secondary works only in 2G.
Xiaomi Redmi 4A comes with a variety of sensors installed, such as an accelerometer, a gyroscope, and a proximity sensor. There is also a GPS chip, FM radio, and even an infrared port on it. The Xiaomi Redmi 4A comes with a non-removable battery of 3120 mAh that should offer it plenty of autonomy.
Regarding its size and weight, the Xiaomi Redmi 4A is rather small and light: it is 5.51 inches (139.9mm) in height, 2.77 inches (70.4mm) in width, 0.33 inches (8.5mm) in thickness, and it weighs only 4.66 oz or 131.5 grams.
If you want more details on the specs and features of the Xiaomi Redmi 4A, visit its web page: Xiaomi Redmi 4A Specifications.
The Xiaomi Redmi 4A offers a simple unboxing experience, but a pleasant one nonetheless. The hardware specifications of this smartphone are not impressive but they are good for its ultra low price tag.
Design and build quality
The Xiaomi Redmi 4A has a classic design, with sharper lines than its predecessors. It is a small smartphone with a 5 inch screen, and a very light one too, mainly because its body is made from polycarbonate. At first glance it looks like the body is metallic but the appearance is misleading.
The hardware buttons are placed in their traditional spots: both the volume rocker and the power buttons are on the top left edge of the smartphone. Although they don't have different textures, you should not have problems identifying which is which because the volume rocker is made from a single piece and it is a lot longer than the power button.
On the left edge, there's the SIM tray which you can eject using the pin from the box or any paper clip you have at hand. The bottom edge holds the micro USB 2.0 port used for charging and data transfers, and the top edge is home for the infrared port and the audio jack.
On the back of the smartphone, you can find the rear camera and the LED flash placed right at the top. Unfortunately, the camera is very close to the edge and that means that you can easily cover it with your fingers while taking photos or recording videos.
On the back, towards the bottom of the smartphone, there is the speaker grille and a silverish MI logo.
The software buttons are all found beneath the display on the front side of the smartphone. We like the fact that they are separated from the screen. However, there are also two things that we did not like about them: one is that they are not backlit so they are hard to identify during the night, and the second is that they are positioned opposite from the standard Android smartphones. From left to right, the Xiaomi Redmi 4A has Apps, Home and Back. The usual order is Back, Home and Apps. It works but you must adjust to this arrangement.
On the top side of the screen, you can find the rather small earpiece and the front camera.
Overall, the Xiaomi Redmi 4A does not disappoint when it comes to design and build quality. Sure, it does not look spectacular, nor does it have a body made from metal or glass like pricier smartphones. However, the polycarbonate body feels well assembled and it should not break easily.
