Instructions for Honor 10 for setting up the camera

Manually setting up photo and video cameras on a smartphone is a task for professionals. The developers at Honor know this, so they equipped the device with a smart camera.

Smart camera in Honor 10

It automatically adapts to the surrounding environment, and itself activates the necessary modes and settings for maximum image quality. The Honor 10 camera has many ready-made presets. You just have to select them by name. If you are photographing food, select the appropriate settings from the list.

Choose the right camera preset for your photo

The “smart camera” operates based on a neural network. By pointing it, the phone determines what is in front of it. And it automatically turns on the mode that is most suitable in a given situation.

Phone Clone - Transfer contacts and other data to Honor 30 smartphone from another smartphone

Transfer data from Android devices

2 Follow the on-screen instructions to download and install Phone Clone on your old device.

Solving possible problems

Now we will briefly consider possible problems that arise during the process of setting up a new Honor device, and methods for solving them.

One of the common failures that you may encounter while following the main part of the instructions is the inability to turn on the device. As a rule, in most cases this means a simple discharge of the battery: connect the smartphone to the charger and wait about an hour - during this time the battery will gain enough energy for the setup process. But if suddenly there is no response when connected to the power supply, this may mean some kind of hardware problem. If the device is new, the best solution is to return to the store and request a replacement under warranty, while for used products you will need to visit a service center.
The next fairly common failure is problems with data transfer, if the appropriate option is selected in step 14. For example, often applications are either not transferred at all, or partially, with data loss. We cannot offer any solution other than installing the problematic software again: alas, this is how the Android OS works, and there is nothing to be done about it.
It may also happen that after configuration, certain functions do not work - for example, a proprietary feature of Huawei and Honor in the form of AI Search. Here we return again to the previously mentioned problem of regional support policy: if, for example, in European versions of devices an almost complete set of capabilities is available, then in phones for the Asian market many will be disabled due to lack of demand or peculiarities of local legislation. Considering that devices produced by the Chinese IT giant are difficult to flash, the only advice we can give here is to look carefully at the model numbers and try not to mess with “gray” devices, since the vast majority of them are Asian, illegally imported into your country. countries.

We are glad that we were able to help you solve the problem. In addition to this article, there are 12,719 more instructions on the site. Add the Lumpics.ru website to your bookmarks (CTRL+D) and we will definitely be useful to you. Thank the author and share the article on social networks.

Call recording

The trend of banning everything has also reached such a necessary option as recording phone calls. In EMUI 9.1 it seems like this feature is present by default.

You can install the APK file as an application in the normal way without ADB and root.

Wired projection Honor 30

You can connect your device to an external display, such as a TV, using a cable.

Use accessories recommended by Huawei and purchased from authorized distributors.

Wired projection via USB Type-C cable

1 You will need a USB Type-C cable. Use a USB Type-C to HDMI, USB Type-C to DP, or USB Type-C to MiniDP cable depending on the type of external display. 2 Connect one end of the USB Type-C cable to your device and the other end to the external display. 3 On your external display, set the input source to HDMI, DP, or MiniDP.

Projection using the docking station

Replacing the screen yourself or in the service

Briefly, the process of disassembling and replacing the Honor 8C display looks like this:

Using a mediator, cut the glue between the frame and the glass, peel off the cover and find the fingerprint scanner cable, unclench the clamp and pull it out. After this, you can remove the cover completely. Next, release the clamps of all the cables that are in front of your eyes (antennas, display matrix, battery, buttons, touchscreen, front camera, two main ones and the bottom board cable). Afterwards, unclip the motherboard from the case and peel off the battery with the bottom board. Use a separator to heat the screen matrix, disconnect the spare parts from the matrix, and glue the new display (already with glass) onto the case and fix it for a day, then assemble it.

If this all sounds confusing, watch the video:

The approximate price of such a procedure at a service center is 700-3000 rubles, depending on the origin of the screen and what exactly needs to be changed - the entire display module, touchscreen or glass. Not every master will undertake to replace them individually - the equipment for gluing a touchscreen to a display is expensive and requires experience.

Busting charging myths

Below we will look at the 4 most common questions about charging batteries.

Myth No. 1. Don't leave your phone plugged in to charge all night

This opinion was formed due to old devices that heated up and could fail. However, manufacturers have long ago solved this problem. A smartphone connected to the network automatically stops receiving power when the battery indicator reaches 100%.

Myth No. 2. You can only charge a completely discharged battery

This misconception also came from older devices that used nickel-containing batteries with the “ Memory Effect ”. All modern devices use lithium polymer batteries and can be charged at any time.

Myth No. 3. Fast charging harms your smartphone

It is not Quick Charge technology that is harmful, but its frequent use. In modern realities, people do not always have the time and patience to leave the phone connected to an outlet for a full charging cycle. They prefer to connect the device to the network several times during the day for short periods of time. But lithium polymer batteries have a certain number of charge cycles, after which their capacity begins to decline. Therefore, it is recommended to perform fast charging infrequently.

Myth No. 4. A new phone needs to be completely discharged and charged several times.

This opinion has been around for a long time, but progress does not stand still. Previously, nickel batteries were used, for which this rule was relevant. You can charge a new phone with lithium batteries based on other rules, which will be discussed later in this article.

Why does my phone battery drain quickly?

Consider the most common reasons.

Large screen , which requires more electricity to display, which means the battery will drain faster.
Screen brightness also affects how long the battery will last. Manually reducing the brightness level or turning on automatic mode will increase the operating time of the phone. Turning on dark mode can partially solve this problem.
Loading the processor during games and using applications greatly drains the battery. Heating or overcooling the device also has a negative effect.
Work of background processes such as Bluetooth, mobile Internet, Wi-Fi, GPS, Google services and others. They should be disabled if they are not currently needed.
Large number of charging cycles . Over time, any smartphone discharges faster and there is no way to avoid this. But following certain rules, which will be described below, you can extend the battery life.
