Description of all the pros and cons of the Oppo A7x smartphone

The new Chinese device supporting the Android 8.1 Oreo operating system is coming to the markets of 2018. This is the Oppo A7x smartphone, a description of all the pros and cons of which will be in this article. It has probably already been registered as a competitor by the best manufacturers producing popular models of multi-core smartphones.

How to choose a reliable and productive smartphone for yourself, and so that it has good functionality? Which company is better? If you take a branded product, how much will a branded device cost? The popularity of the models of many manufacturers is almost equal, which one is better to buy? Or maybe Chinese! The rating of high-quality models of young companies of Chinese manufacturers is almost on par with many brand-name corporations that have won the name. An indispensable advantage is inexpensive, budget models with high parameters, and these are the main selection criteria. Therefore, it is proposed to consider the advantages and disadvantages of the Oppo A7x smartphone.

First, let's get acquainted with the technical characteristics in order to understand that we are talking about a really worthwhile car, and even at a relatively favorable price.

Main technical characteristics

The processor brand MediaTek Helio P60 of this smartphone contains 4 cores ARM Cortex-A53 and 4 - ARM Cortex-A73. The maximum processor frequency is 2.0 GHz. The chip is made using 12 nano-meter technology. The GPU is an ARM Mali-G72MP3 accelerator. The system has 4 GB of RAM and up to 128 GB of built-in solid state memory. There is a slot for installing a micro SD memory card. Micro-USB data output port. Headphone output - 3.5 mm jack.

The smartphone is powered by a non-removable lithium-polymer battery with a capacity of 4.23 A / h. The charge is enough for 1 day of semi-active work. Supports 2 sim cards dual sim. There is a radio, there is also a GPS function.

The screen of the described device has a size of 6.3 inches, a resolution of 2340 X 1080 pixels. At the top of the screen there is a small drop-shaped notch, a feature of this novelty. This cutout is left for the front camera with a resolution of 8 or 16 Mp.

The camera on the back of the smartphone is dual. The first is a sensor with a resolution of about 2 Mp, the second is a photo-video camera with a resolution of 16 megapixels. A dual LED flash is installed near them. There is a fingerprint scanning sensor that takes a fingerprint.

The software allows for scene type detection and face recognition. Recognition of 296 facial features is possible. There are also modes for photographing documents, business cards, schedules, and more.

Dimensions: height 156.7 cm; width 74 cm; thickness 8 mm. The materials of the device body are metal, glass. The smartphone weighs 170 grams. Average price is about $ 300.

Options: smartphone; instruction; Charger; USB cable - Micro-USB; headphones, the length of the cord is not small. Some users consider the Micro-USB connector a disadvantage.

The function of unlocking the smartphone by fingerprints for some, even eminent devices, failed. Especially if the driver programs are not installed from the official site. Just like the face recognition function, it works only with good consecration, if the camera is at a right angle. There may not always be such conditions if you need to urgently turn on this tricky technique. It is not known how this smartphone will behave if similar devices with these functions had serious problems when using them.

Therefore, it is better not to tempt new software that has not yet been reviewed and use simple and long-proven security measures: a pattern or a regular traditional password. Unlocking will be fast and reliable, and secure. And since the new Oppo A7x smartphone only goes on sale in September 2018, and as already written, there are no reviews on its use yet, it is proposed to consider its work based on its predecessors, comparing their characteristics.

Description of the predecessor Oppo A3s

This device has a large number of settings, there is a possibility of customization. You can easily change the order and arrangement of the on-screen buttons. And then turn on the button control.

A plus is the rationality of using screen space from the sides of the protrusion. However, this can be a disadvantage when using the instrument in a carrying case. Certain types of covers may interfere with ease of use. Although the cover is best used, especially in the case of frequent movements and travel. There is a convenient function in the "gallery" - recording an image or taking a screenshot. The downside is a certain inconvenience when closing heavy animations, of which there are a lot. Also, the additional complexity and inconvenience of closing notifications in the curtain.

I am glad to be able to enable conversation recording. At the same time, the sound and quality of the conversation of the interlocutor are very legible and good. The recording can be easily edited and dropped into a memory file. The earpiece speaker is loud enough that vibration distortion appears at full volume.

An interesting application is offered by Oppo to its smartphone owners - the Music Party player. Its feature is the synchronization of Oppo devices when playing one song by several phones at the same time.

The camera has a function such as autofocus. But there is a small minus, the sharpness of objects in the foreground is a little blurry. Video focusing is good, but there are slight jerks when recording in high quality. This flaw can be corrected in a video editor on a personal computer. Although there is also a function of intelligent correction of the appearance of the photographed face, the images are obtained with slight changes and seem to be downloaded from the Internet. The downside is the lack of manual adjustments. While this feature can be very useful to quickly fix the unattractiveness of a sleeping face, it can be a big plus.

However, it should be noted that the main one, as well as the Oppo A7x brand graphics processor, has much higher performance. And the RAM operating at a slightly higher frequency is 2 times more. It is more comfortable and nimble.

Description of the predecessor Oppo F9

This smartphone has the same processor as the described device. RAM can be 2 GB more. But with a slightly lower screen resolution of 2280 X 1080. Recall that the described one has 2340 X 1080.Although the Oppo A7x's teardrop notch is inherited from the Oppo F9. The size is not mentioned for nothing, as many Oppo F9 users claim that the android is very comfortable in the hand. It is convenient to read books, watch movies, view browser pages.

The device body is made of composite material. It feels like plastic and doesn't slip out of your hands, which is a big plus. There are also disadvantages: Bluetooth 5th generation is not supported; not supported by NFC.

This device has such an opportunity - fast battery charging, VOOC technology. In this mode, a half-discharged battery is charged to 100% in half an hour. The Oppo A7x also has such a mode.

Since the hardware of the described devices Oppo F9 and Oppo A7x is almost the same, the capabilities will be almost the same. However, you should compare the Oppo A7x with some models of this company in order to have a better idea of ​​it.

Possible problems of Android 8.1 OS and ways to solve them

Updating the operating system to version 8.1 has long been a beta for testing and patching. In the full version, problems still continue to appear on some smartphones.

Installation problems

If you have problems downloading and installing or manually installing an update to Android 8.1 Oreo from a third-party download, then it is better to use the update over the air. Naturally, in this case, it is better to completely discharge the battery and then recharge it to 100%.

Fast battery drain

Usually this problem is solved by a simple reboot.But if this did not help, then you need to pay attention to the applications running in the background. Fortunately, the new version of Android 8.1 Oreo provides an indication of battery consumption by applications running in the background. If the number is large, then they can be disabled. Servers can also consume a lot, to fix this problem you need to clear the cache. And check how long the charge lasts when Wi-Fi and Bluetooth are off. If this does not help, then you need to make a full reset of all settings to the factory settings. If the battery is still discharging quickly, then it needs to be replaced. Less commonly, phone repair or replacement.

Battery charging problems

Most often, this problem is with the charger cable, since this smartphone consumes a rather large charge current, poor-quality cords and connectors often fail. You can check by trying to charge the device via a micro-USB cable from a computer, having previously learned the characteristics of the port used. It must be rated for a current of at least 2 A.

Problems with mobile internet connection

If restarting the Internet connection did not give positive results, then you can try the "airplane" mode. In this mode, a minimum of applications are used, and if the problem is resolved, then the reason may be in the recently installed application. You should try to calculate it and replace it with a compatible one. In the mobile networks option there is an LTE connection function, you can try to restart it (turn it off and on). As a last resort, reset your smartphone to factory settings.

Bluetooth problems

In case of problems with Bluetooth, you can try to turn it off and turn it on again. This option can be found under quick settings and system settings. In this case, remove all non-working Bluetooth connections. Try to connect again.

Wi-Fi network problems

They can arise at any second and there are also many reasons. Problems can also be in the modem, it can be checked with another device. It is necessary to check the connection settings, change the connection name and password. You can reset the network settings and configure in a new way.

Application crashes

As always, start by rebooting the OS. Next, you need to check for new installed updates for these applications. The most common reason is that these updates are incompatible. You can try to check their compatibility and read reviews about these updates, or it is best to remove them and not use them.

You can also go to the storage section and clear data, also clear the cache.

If this version of the application has never worked on your smartphone before, then you need to try another one.

Sound problems

First, you need to determine where the problem is, in the application or in the smartphone itself. If the sound disappears after installing any applications or updating drivers, then the reason may be the incompatibility of the new software. Try to update the application to the latest version, or install the one on which the phone worked earlier. Also check the dynamics for dirt or damage. Check the operation of the headphones, if possible, the sound output to Bluetooth.
