Oppo A7 smartphone - pros and cons

Oppo is trying to keep up with the times, and it does it well. Always trying to do something new and unique. To prove this, it is worth giving an example. Oppo find x Is the world's first mobile device with a pop-up camera. At first, potential buyers did not believe in such a miracle of technology, but the developers were able to convince customers that such a device could last at least 5 years. Now the Oppo Find X is being swept off the shelves of electronics stores in no time. In addition, this company has released many more interesting models. In this article, we will review the new low-cost Oppo A7, which also looks quite solid.

Specifications

All main parameters are shown in the table.

Detailed description of technical characteristics

Housing

The body is large enough. Its width is 75.4 mm, length - 155.9 mm, and thickness - 8.1 mm. Sometimes developers ignore the camera or other bulging areas to save time and money. This means that the camera may not take pictures clearly due to a manufacturer's flaw.

This device weighs as much as 258 grams. This weight does not make it feel like you are holding a lightweight plastic toy. It is terribly inconvenient to carry in your pocket. Operation also causes discomfort, since the hand quickly gets tired and you have to rest. Even after 5 minutes of talking, you will feel pain in your arm, which is very unpleasant.

Sold in gold and blue colors. As you can see, the choice is small. Only 2 colors.

The body itself is made of aluminum alloy.

Screen

The display is equipped with an IPS matrix. This means that the screen is made of cheap material, typical for budget and mid-range phones (although until recently this type of matrix was installed on the Iphone). The fact is that in the dark it is comfortable to use at the minimum brightness, and on a bright sunny day at the maximum (but in this case the battery will drain quickly). Also, eyes get tired very quickly from some displays with this type of matrix.

The diagonal of the screen is as much as 6.2 inches. This phone is large enough to fit in your pocket. For such devices, you need to wear a purse.

The display is 67.31 mm wide and 142.24 mm long.

The aspect ratio is 18: 9. This screen resolution has become fashionable since the beginning of this year.

The pixel density per inch is only 271 ppi. This is the average density level. The higher the pixel density, the better the image quality and the sharper the colors.

The number of displayed colors and shades is about 24 million.

81.89% - this is the part of the entire device that is occupied by the screen.

However, manufacturers are constantly increasing the screen area on the front side of the case.There are even bezel-less phones where the screen area is more than 95% of the device.

Iron

The gadget is equipped with a budget processor Qualcomm Snapdragon 450. This processor is responsible for power consumption, operating speed, quality of communication and navigation, as well as for speed and other functions of the phone or tablet.

The processor capacity is 64 bits. Equipped with eight cores. The more cores, the greater the multitasking of the device.

The maximum frequency is 1800 MHz. This metric affects performance.

Qualcomm Adreno 506 serves as a GPU.

Micro USB is used for charging.

The battery capacity is 4230 milliampere hours, which is good enough for a modern device. Moreover, if the device runs on a budgetary and not very powerful processor, then this means that the charge will last for a long time. For example, in standby mode, it can last more than a week, and in reading mode for more than 15 hours, provided that the screen did not turn off at all.

Battery type: Li-polymer.

Cameras

Main camera

CMOS (complementary metal-oxide semiconductor) is the type of sensor in the main camera. This type is installed on 99.99% of mobile devices. The main camera module is double.

Aperture f / 2.2. (the larger the aperture value, the lower the quality of shooting in low light, the best indicator is 1.8)

A dual LED flash is installed here. This type allows you to shine constantly, however, the video quality in the dark is low. Better pictures and videos are obtained using a xenon flash, but it is practically not installed on mobile phones. If you want to get a professional photo or video, then it is better to buy a good camera for the same price.

The maximum photo resolution is 4160 x 3120 pixels. This is equal to 13 megapixels.

The video is shot at a resolution of 1920 x 1080 pixels.

The video frame rate is 30 frames per second.

Additional camera functions:

• Autofocus;
• Burst shooting;
• Digital zoom;
• Geographic tags;
• Panoramic shooting;
• HDR shooting;
• Touch focus;

Examples of photos:

Front-camera

The front camera received an f / 2.0 aperture and a resolution of 15.99 MP. It's even slightly better than the main camera. It seems that the manufacturers focused on the quality of the selfies, rather than the quality of the main camera. Indeed, the pictures are decent.

Communication and communications

As a means of communication with the world, 2 Nano-SIMs serve. They support the following digital communication formats:

• GSM 850 MHz;
• GSM 900 MHz;
• GSM 1800 MHz;
• GSM 1900 MHz.

Also supports 4 Jie communication type.

There is also Wi-Fi. The phone supports connection to almost all types of routers.

Bluetooth A2DP (Advanced Audio Distribution Profile) options.

In addition, a standard 3.5 mm headphone jack is provided. Now the vast majority of manufacturers are abandoning this connector, although until this year it was relevant for almost all mobile phones.

This device supports almost all types of video and audio. Unfortunately, there is no radio here. Although, if you look from the other side, then few people listen to the radio now, and even more so on the phone.
