Smartphone Oppo A7 - advantages and disadvantages

Oppo is trying to keep up with the times, and it does it very 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 retractable 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 Oppo Find X is being swept off the shelves of electronics stores in the shortest possible time. In addition, this company has released many other interesting models. In this article, we will review the new inexpensive Oppo A7, which also looks quite solid.

Specifications

All main parameters are given in the table.

Detailed specification description

Frame

The body is big enough. Its width is 75.4 mm, its length is 155.9 mm, and its thickness is 8.1 mm. Sometimes developers ignore the camera or other bulges to save time and money. This means that the camera may not take clear pictures due to a manufacturer's defect.

Such a device weighs as much as 258 grams. This weight does not give the feeling that you are taking a light plastic toy in your hand. It is terribly uncomfortable to carry in your pocket. Operation also causes discomfort, because the hand gets tired quickly and you have to take a break. Even after 5 minutes of talking, pain in the arm will be felt, 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 middle-class 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 minimum brightness, and on a bright sunny day at maximum (but in this case the battery will quickly run out). Also, from some displays with this type of matrix, the eyes get tired very quickly.

The screen diagonal is as much as 6.2 inches. This phone is big enough not to fit in your pocket. For such devices, you need to wear a purse.

The display is 67.31mm wide and 142.24mm long.

Aspect ratio 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 level of density. The higher the pixel density, the better the image quality and the clearer the colors.

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

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

However, manufacturers are constantly increasing the screen area on the front side of the case. Already there are even frameless phones, where the screen area occupies more than 95% of the device.

Iron

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

The processor bit depth is 64 bits. Equipped with eight cores. The more cores, the more multitasking the device.

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

Qualcomm Adreno 506 serves as the GPU.

Micro USB is used for charging.

The battery capacity is 4230 milliamp hours, which is good enough for a modern device. Moreover, if the device runs on a budget 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 does not turn off at all.

Battery type: Li-polymer.

cameras

Main camera

CMOS (complementary metal-oxide semiconductor) is the name of the main camera sensor type. 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 value is 1.8)

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's 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.

Photo examples:

Front-camera

The front camera received an aperture of f/2.0 and a resolution of 15.99 MP. It's even slightly better than the main camera. It seems that manufacturers have focused on the quality of the selfie, rather than the quality of the main camera. And 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 4G connection type.

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

bluetooth version 4.2.

A2DP (Advanced Audio Distribution Profile) bluetooth options.

It also has a standard 3.5mm headphone jack.Now the vast majority of manufacturers refuse 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, few people listen to the radio now, and even more so on the phone.
