How to solve the black screen when calling and the black screen when the phone calls

In general, there are many reasons for this.

It is recommended to restore factory settings or flash the computer to see if the screen is still black.

If there is still a problem, you should consider whether it is a hardware problem! If it's hardware, it can generally only be repaired after sales.

Causes of smart black screen.

1. Mobile phone crash memory problem: Under normal circumstances, when the mobile phone stores too many things, many friends can feel that the mobile phone is running too slowly, and when their mobile phone is occupied by 80% of the memory that can be driven, it may crash.

2. The problem of the second contact of the mobile phone crash: This is the loosening of the contact of the mobile phone screen, which is not a big problem, but it can directly lead to the black screen of the mobile phone, which is difficult to find and can only be found after a lot of tests, which is generally caused by the mobile phone being bumped.

3. Mobile phone crash three battery problems: It is common for many mobile phones to have a black screen after using it for a long time, the main reason is that the effective use time of the mobile phone battery is 1 year, or it is three years but there is a problem in one year, and excessive use leads to the aging of the mobile phone's battery and insufficient voltage.

4. The problem of four conflicts in mobile phone crash: There are many applications for smartphones nowadays, but there are some software that are born with conflicts, which can also lead to a black screen, so the black screen after installing a lot of software is basically this reason.

5. The problem of mobile phone crash and five flashing: Many people are keen to brush the phone and use a better system, in fact, some system mobile phones are not very supportive, and there is also a complete flash, which leads to the inevitable black screen when using it in the future.

Xiaomi uses the sensor to turn off the screen when it comes to calling, don't cover the vicinity of the earpiece when there is an incoming call, the best way is to turn off the proximity sensor: Call Log—Menu—Settings—Answering Status—Turn off and enable the proximity sensor。 However, the disadvantage of this is that the screen will always be on when you come**and** answer**, knowing that the call is over.

It is suitable for iPhone, Huawei, Xiaomi, OPPO and most other brands.

1. This may be due to the proximity sensor being turned on.

2. When you are talking, you block the photosensitive hole (there are two on the left side of the earpiece), and the screen will turn on when you take it off your ear.

3. It may also be due to the problem that the sensor is blocked by the mobile phone film.

4. When the hardware of the mobile phone fails, when the distance sensor fails, it is impossible to correctly judge whether there is an object approaching, which may cause a misjudgment when dialing ** and then turn off the mobile phone screen.

The phone comes to the black screen solution: You can turn off the "Enable Proximity Sensor". Enter System Settings, Programs, **, Answer Status, Enable the Distance Sensor, and Turn Off; Remember to leave the part of the sensor empty when applying the film, if it still doesn't work, tear off the protective film of the mobile phone; Therefore, it is recommended to send the mobile phone to an officially designated repair center for repair; If the phone system is faulty, it is recommended to try again after resetting the factory settings, or you can also try again after upgrading to a new system version.

The reasons for the black screen of incoming calls on your phone are as follows:1. It may be caused by the proximity sensor being turned on, just turn it off.

2. When making a call, it is caused by blocking the photosensitive hole, which depends on whether the surface of the mobile phone is clean.

3. It may also be due to the sensor being blocked by the mobile phone film, which is a more common reason.

4. If the hardware of the mobile phone fails, when the distance sensor fails, it is impossible to correctly judge whether there is an object, which may cause the wrong judgment of no object and turn off the mobile phone screen when dialing **.

The solution to the black screen of the phone is as follows:

1. When the user puts the mobile phone close to the ear to answer, the mobile phone will turn off the screen by default and keep the answering state, which is a normal phenomenon. By default, the phone's proximity sensor will automatically turn off the screen when the phone is close to the surface of the object, so as to reduce the screen misoperation, etc.

2. If the phone calls are black without any operation, you need to confirm whether the distance sensor on the top of the mobile phone is blocked by foreign objects (such as opaque film), and tear off the film to solve the problem.

If you are using an OPPO phone, there is a proximity sensor next to the earpiece of the mobile phone, if the proximity sensor is blocked during an incoming call or call (such as answering close to your ear), the screen will be black at this time, so as to avoid misoperation caused by face and screen contact.

When making a call, the proximity sensor is not occluded, and the screen goes black automatically.

1. Check whether the film covers the distance sensor, and tear off the film for observation;

2. Restore the phone to factory settings after backing up important data (contacts, text messages, etc.), and check for abnormalities caused by third-party software;

The above methods can't solve the problem, please back up your mobile phone information, and bring your mobile phone, invoice and warranty card to the nearest local OPPO customer service center for testing and processing.

4. If the system crashes, you can restart the mobile phone wheel for detection.

5. The background program of the mobile phone runs too much, and the black screen of the card appears in the pants and the message. <>

Answer: First, because most of the current smart phones are installed with a distance sensor next to the earpiece, when you hit ** and the face is close, the screen of the mobile phone will automatically go off, and when your mobile phone is far away from the face, the mobile phone screen will light up again, which is to save the power of your mobile phone and increase the time you use the mobile phone.

You can give it a try, cover the top of the screen with your hand, and the phone screen will automatically dim, take your hand away, and the screen will light up again.

Second, the black screen of the call first check whether the film is dirty to block the proximity sensor (next to the earpiece), if there is a cleaning or replacement of the film can be restored to normal, if it is not good, there are several reasons for this phenomenon:

You can first see if it is blocked, if it is, stay away, or turn off the distance sensor function, and the Android phone can choose to open [Settings] - [More** Settings] - [Status Settings when calling] - [Enable or turn off the distance sensor]. Or check whether there is any foreign object in the earpiece attachment above the front of the mobile phone, if so, please clean it up, and the general problem can be solved;

2. If the distance sensor is faulty, it is recommended to make a judgment on whether there is an object approaching;

3. The sensor is caused by the lack of leather pads, which generally occurs after disassembling or changing the screen. The solution is to attach small pads under the two small holes above the original touchscreen. If the black screen can't be hung**, you can go to the settings below and select the power button to hang up when pressed**;
