iPhone won’t turn on after being dropped from a height

Here the cause of the breakdown is very clear. In most cases, one of the device’s cables snaps off: battery, screen, power button, etc. If the smartphone really hit hard, then the soldering on the motherboard could be broken, or one of the microcircuits could break. What to do? If you have the skills, disassemble and inspect the iPhone for loose cables, otherwise, carry the device to the service center, the repair of such a problem can be protracted, so please be patient.

iPhone Won’t Turn On After Car Charging

iPhone 4 / 4S may not turn on due to the inability of most users to properly use the car charger. Improper handling of the car charger can damage the battery, and in the worst case, you will have to change the power controller or repair a specific circuit in the power supply. This usually takes no more than two days. Therefore, if your device turns off completely after using car charger, definitely take your iPhone to the service.

iPhone won’t turn on after flashing

If during the firmware your iPhone 4 / 4S turned off completely, then there are two options for the development of events:

  • The Nor Flash. a microcircuit of the GSM module fails. It is this module that is responsible for the correct calibration of all operators, and if a failure occurs during the firmware, then your smartphone will not be able to make calls in the future;
  • The NAND Flash fails. the microcircuit on which all your data is stored: photos, videos, contacts, programs, etc. Since iPhones do not have the ability to install additional memory cards, the device will refuse to turn on without the correct operation of this microcircuit.

Some may panic after an unsuccessful flashing. What to do? I need to flash my iPhone again. Why is it crashing? It can happen exactly like a crash in programs on a computer, no wonder. At the end of the article, we will also tell you how to restore the system yourself.

iPhone won’t turn on due to broken charging connector

This reason can be described in a slightly different way. iPhone can’t be charged (that’s why it won’t turn on) because the charging connector is not working. a fairly common problem, especially if you carry the device in your jeans. Why is this happening? Because over time, the nest becomes heavily clogged with dust and simply stops working. Sometimes the connector may break when trying to connect the charger.

What to do? Within the home, you can try to gently clean the connector, although we still recommend contacting a workshop, as this problem is usually solved by craftsmen within one hour. It is also worth remembering that charging with non-original chargers can damage the connector.

How to solve a problem

  • The problem may be associated with the proximity sensor, or rather with its incorrect operation. How to check this sensor, read the article: Proximity sensor does not work.
  • Also, the problem may be related to improper operation of the smartphone software. To identify it, try to boot your smartphone in Safe Mode.
  • Also try changing the Time Before Screen Turns Off option found in Settings Screen & Gestures. You probably have the lowest value set.
  • The screen may not light up when a wired, wireless headset or hearing aid is connected to the phone. Settings menu. Call settings. Call settings for SIM. In this menu, uncheck the box next to “Hearing aids” if you do not use them.
  • As a last resort, do a factory reset.

The problem may appear after an unsuccessful update of the HTC smartphone software. In this case, you will have to wait for the next official update.

If on Android the screen does not turn on after a call or does not go out during a call when you bring it to your ear, then you should look for the cause of the problem in the proximity sensor. If it breaks down, the device cannot correctly determine the position in space, so the screen does not light up, but the phone works.

This article is suitable for all brands that produce phones on Android 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Attention! You can ask your question to a specialist at the end of the article.

Screen problems when calling on Android

The main function of the proximity sensor is to automatically turn on and off the backlight during a call. This saves battery power and prevents accidental pressing of your ear or cheek on the touch screen of your gadget.

If your Android device does not turn off during a call, or the screen does not turn on after the call ends, then the problem should be looked for in the sensor’s operation. The reasons may be as follows:

  • Poor visibility (covered / covered with a protective film or cover).
  • Out of RAM.
  • Problems with firmware.
  • Moisture ingress.
  • Mechanical impact and damage to the loop or other components.

Wipe the screen thoroughly before proceeding with software-based troubleshooting. Pay special attention to the upper part, where the proximity sensor is located. If a film or glass is glued to the display, then over time they can lose transparency and also interfere with the sensor.

Then check the call settings. perhaps the parameters are incorrectly set in them, and the sensor is simply turned off. This option is not available in all phones, but it’s worth checking.

  • Open the settings and go to the section “My devices” or “Options”.
  • On the Calls tab, make sure there is a check mark next to Proximity Sensor.


Also, make sure the system has enough RAM to operate the sensor. Open the list of applications in the settings and on the “Running” tab see how much RAM the phone is using. If you find a shortage, quit unnecessary applications.

If everything is set correctly in the settings, but the sensor does not work, make a backup copy of important data and reset the Android settings to the factory state. If the problem persists after a hard reset, you will have to flash the phone. If no software methods, including flashing, have fixed the problem, it is recommended to contact the service center to diagnose hardware malfunctions.

Android screen problems after sleep mode

Another problem that can arise with the screen is that it does not turn on after sleeping. It might be white screen or black, but the phone is working. If you are faced with such a situation, then know that the reasons can also be software and hardware in nature:

  • Out of RAM.
  • Problems with firmware.
  • Incorrect operation of the power button.
  • Mechanical impact (impact, fall).
  • Ingress of moisture inside the case.

If the phone does not turn on, but vibrates when there is an incoming call or other actions, then there is a high probability that the problem can be fixed without contacting a service center. Clean up the RAM from unnecessary processes by shutting down the applications that are unnecessary at the moment. If this does not help, make a backup of important data and reset the system settings to the factory state.

If the software methods did not help, it is recommended to contact the service center for diagnostics and phone repair. In case of problems with the power button, as well as after mechanical stress and moisture ingress, it may be necessary to replace components.

When you call, it goes out and does not turn on

On some Xiaomi models, due to operation, an unpleasant bug appears: when the smartphone is moved away from the ear, the screen does not light up, which makes it impossible to reset the call.

This problem is fixed either by rebooting or cleaning the phone from “heavy” applications that clog the device’s RAM.

If this does not help, the point is in the firmware itself: try reflashing your smartphone: for this it is better to contact the service center; or you can calibrate the proximity sensor.

Does not go out when talking

If, while talking on the phone, you suddenly notice that the screen does not turn off, then the problem is in the proximity sensor.

The proximity sensor on Xiaomi smartphones is responsible for turning off the display during a call and automatically adjusting the screen brightness.

There are several options for solving this problem.

A similar situation occurs either when the sensor fails, or when it is turned off by software or manually. To fix the error, you need to enable (restart) the sensor through the settings:

Go to “System Apps” or “All Apps”.

Scroll down and turn on the proximity sensor using the switch, or restart it if it’s already on.

Restart your smartphone and check for the problem.

The standard location of the sensor is near the earpiece or front camera, depending on the model. Perhaps the sensor is covered by a protective glass or film: gently bend the edge of the film or completely remove the protective glass, and then check the operation of the sensor. Also make sure the sensor is not clogged with dust or foreign objects.

To check if the sensor is working, turn on the camera on another phone and point it at the Xiaomi sensor, and then call the tested smartphone. During a call through the camera of another phone, you will see the sensor flickering.

If there is no flicker, then the sensor is disabled or broken.

Doesn’t turn on after talking

If after the end of the conversation on the smartphone the screen does not turn on, the matter is in the inadequate operation of the proximity sensor. You can fix this using the methods described above: restart the sensor itself, or check if the sensor does not overlap the protective glass.

In addition, there are several more options for solving the problem.

This function protects the screen from accidental taps when the smartphone is in your and its performance depends on the proximity sensor. However, on some Xiaomi models, this mode may mistakenly lock the screen when the smartphone is in the hands.

To check if mode is causing the problem, just turn it off. To do this, go to “Settings”. “Lock and Protection”. “Advanced Settings” and turn the switch to the “Off” position.

If you disable this mode, protection against accidental clicks in the will not work.

This way of solving the problem is more radical. it will completely reset your phone settings, delete all applications and user files.

How to factory reset Xiaomi:

  • Go to “Settings”. “System and device”. “Advanced settings”.
  • Scroll down and find the “Restore and reset” item.
  • If necessary, configure the creation of backups and click the reset button.
  • Click “Reset Settings”.

If necessary, the system allows you to save the user’s personal data, to do this, drag the “User data” slider to the right.

You can also reset the settings to factory settings using the recovery menu (power button and volume up button). This menu allows you to make a full-fledged wipe, however, if your device has a warranty, it is not advisable to do this.

Calibration of sensors

If the above methods did not help, the last one remains. the calibration of the proximity sensor:

Open “Calls” and enter the combination ###.

The engineering menu will open on the screen (you do not need to press the call button).

If “Far” or “Near” appears on the screen, then the sensor is working properly, you can calibrate.

Press “Calibration”, place your phone on a flat surface and follow the instructions on the screen.

If the zeros change to any other numbers, everything is in order with the sensor.

When the calibration is complete, the screen will show “Successfully”. If, after that, the screen does not go out during a call, you need to contact the service center.

Usually, if the iphone 5s, 6, 6, plus, 7, 7 plus, 8 does not turn on after repairing the screen, the problem is in the wizard who dealt with your device or in your wrong actions when he changed the display himself. A person made a mistake at some stage in the assembly or disassembly of the iPhone.

  • The screen module is defective (defective or not original).
  • The loop from the monitor module is interrupted.
  • Burned out power controller u2.
  • During assembly, the screws were mixed up and screwed into the wrong slots, as a result, a short circuit.

Everything can be repaired, another question is whether it will be profitable as a result. Sometimes it is easier to throw away some of the microcircuits and replace them with new ones than to try to repair a dead patient. In this section, we will try to fix the iphone 5 with our own hands, which does not show signs of life, after replacing the screen.

What to do iPhone won’t turn on after replacing display module?

There are quite a few such stories, the low qualifications of workers who study by video from YouTube have made a lot of devices unusable. Today, in this article, we will give a clear answer, what to do if the 8, 7, 6 or iphone 5 does not show signs of life after replacing the display module.

DIY repair

It seems like the cheapest and most reliable way, but not always. It happens that after self-replacing the screen module on the iPhone 5, it no longer turns on, the causes and symptoms were discussed above, now we will find out how to fix it all. By tradition, there will be a video instruction at the bottom of the article.

  • We check the module on another iphone 7 or other suitable model, if it refuses to work on a patient.
  • A hard loop, from a non-original Chinese spare part it becomes a headache, to eliminate this, it is enough to glue a piece of soft material, for example, a sponge for washing dishes.
  • We check the correct position of the screws, long screws interrupt the conductive paths on the lower boards and lead to delamination.
  • Conductive tracks can also be restored with your own hands, how to do it correctly, look at the video.

Repair in service

An expensive pleasure, but worth it, especially if the iphone 5 does not show signs of life after the repair made by you personally. Reworking the work of the wizard after replacing the display or after replacing the case with an iphone 6 can be very expensive, since an unskilled person can make mistakes that are fatal for the equipment.

, especially if you have to re-solder the U2 controller or any other module.

IPhone screen not responding to touch

And get the best deals from trusted masters.

  • Compare and choose the best conditions
  • Feedback from interested professionals only
  • Don’t waste time communicating with intermediaries

The reason that the iPhone screen does not respond after touching your finger may be moisture, dust, or mechanical damage. The main indicator of a malfunction of the touchscreen is a partial response of the touchscreen to pressing or random typing. In some cases, on iPhone, the screen does not respond to touch because the smartphone is frozen. By following a series of procedures, you will be able to determine why the display is performing poorly.

What to do if the sensor stops working

If your iPhone screen stops responding, you don’t always need to replace the display. In some cases, you can independently determine the cause of the problem and fix it. First, eliminate the possibility of damage to the case or screen surface.

If the internal components break, only a qualified technician can repair the iPhone.

If iPhone screen freezes, follow these steps:

  • use the power button to reboot the device (hold the button for a few seconds)
  • remove unlicensed software from iPhone
  • reflash the device

If, after performing such actions, the iPhone screen freezes, and there is no reaction to pressing the buttons, you must perform a complete reboot of the device. To do this, you need to simultaneously hold down the “Home” and “Power” buttons for 20 seconds. The smartphone will then erase the RAM and restart the phone.

If after that part of the screen or the entire display still does not respond well to finger presses, the sensor needs to be replaced.

Common causes of breakage

Most often, the iPhone screen does not respond to the touch of a finger after a fall, liquid penetration through cracks or due to other mechanical damage. The following defects are quite rare causes of problems:

  • touchscreen wear
  • high load of RAM (iPhone screen stopped responding, and buttons do not respond because the phone is frozen)
  • iPhone system malfunction (smartphone does not respond to button presses)
  • overheating of iPhones (in such cases, part of the screen does not respond to touch)

It is easy to determine the presence of problems in the operation of the sensor, the following failures are observed:

  • partly or completely unresponsive to iPhone touch
  • in certain parts of the display, the iPhone screen freezes when you touch your finger
  • the screen responds with a delay to touch
  • pages are flipped incorrectly
  • the sensor stopped responding to touches and spontaneously types text

To avoid problems with iPhone displays due to mechanical damage, the manufacturer recommends gluing glass or film to the surface of the screen.

Installing a new display module

The iPhone screen cannot be replaced separately from the sensor or touchscreen. If the display does not respond well to pressing due to damage, then a new module needs to be installed. The exact cause of the malfunction can be identified by qualified specialists using computer and mechanical diagnostics. Wizards will accurately determine why the smartphone is frozen, the device does not restart, or part of the screen does not work.

If the sensor does not respond well to touch or has stopped working altogether, and the programs do not respond to button presses, then contact the performers Yuda. Experts will efficiently and professionally install new display modules on iPhones of all generations.

  • fast and accurate mechanical and computer diagnostics of the device (they will accurately determine why a part of the display does not respond to pressing)
  • complex repairs using original spare parts
  • troubleshooting at home or in a service center at a convenient time for you

Technicians also provide additional services, such as replacing buttons or worn parts of the phone.

Experts will quickly diagnose and find out why the iPhone screen is not responding, after which, in accordance with the manufacturer’s recommendations, they will fix the breakage and repair the iPhone.

Transparent protective film or glass

In addition to replacing the touchscreen, a situation where the proximity sensor of the iPhone does not work can be caused by a protective film or glass. precisely, its dark shade. Due to the shading, the distance sensor, although fully functional, will not be triggered. The solution to this problem is to remove the protective film or glass and replace it with another transparent one, which is quite logical.

There are a huge number of such accessories on the market now, so there should be no problems with choosing the right one. The main thing to remember is to take only a transparent protective glass.!

It should be noted that if you put on a protective film or glass of a dark shade on your iPhone for a long time and before that there were no such problems, then most likely the sensor on the phone has failed for another reason. In this case, it is strongly recommended to contact the wizard.

Removing pollution

The cause of the problem we are considering may be the notorious dust that gets inside the device when the tightness is broken. In order to wipe the phone from the inside, you will need to disassemble the case, and gently, without pressure, wipe the circuits and the case from visible debris.

Phone recovery

If it’s not about replacing the touchscreen and a dark protective film or glass, then the sensor may not work due to failures in the operating system. Therefore, before going to the official service center in order to fix the iPhone 5 or any other gadget from Apple, we try to reboot. It is very simple to do this. look at the picture and press the marked buttons.

In order to reset all software errors, you need to format your phone. This can be done using iTunes. How exactly the procedure is performed, read and see here in this article.

The iPhone screen does not block and does not go out during a conversation, causes and remedies.

The proximity sensor in smartphones, including the iPhone, performs such a function as dimming the screen during a call. The function is activated at the moment when it comes into contact with something opaque. When a person makes or answers a call, that something is the ear. Today we will talk about why the screen does not go out when talking on the phone and what you can do in this case on your own, without the help of a specialist, including how to check the proximity sensor.

A small piece of scotch tape

Most often, the proximity sensor in a smartphone loses its functionality after replacing the touchscreen. In order to solve this problem, it is enough to glue a small piece of scotch tape in this place and paint over with a dark marker, preferably black. This method has been tried many times and has always been effective.

Instead of tape, you can use a rubber band. Cut a piece about 5 mm long and place it between the light and distance mechanisms. This method, as noted by experts and ordinary people, also helps to solve the problem when the function of turning off the display on the iPhone does not work as it should, when approaching in an opaque object.

Of course, in order for the distance sensor to be available for repair, the device will have to be disassembled, at least remove the display module. There are a lot of instructions on how to do this for owners of iPhone of different models on the Internet. To get started, check out so as not to break wood and spoil a valuable spare part. The screens are very fragile and, if removed incorrectly, turn into a pile of glass shards.

As a rule, the distance sensor after replacing the display does not work if the procedure was carried out by people who are not familiar with all the intricacies of opening and repairing the iPhone 5 and other Apple products. Therefore, to replace the display on the iPhone, it is best to contact real professionals in their field, specialists in whom you are 100% sure, preferably to an official service center.

In addition, only there you will receive a guarantee for work and spare parts several months long, in contrast to private servicemen who limit warranty obligations to 2-3 weeks.

Disable a module

If you are, on the contrary, wondering: “How to disable the proximity sensor on the iPhone”, then you can use one of the following methods:

  • Download Smart Screen Off app. The program allows you to calibrate, adjust the moments of switching on and off.
  • Dial the combination “# # #”. a software shutdown method, wired by engineers into the bowels of the iOs operating system.
  • Disassembling a smartphone and removing the proximity sensor is perhaps the most radical way.

Repairing the loop

The situation when the screen does not go out, in addition to everything mentioned above, can be caused by the breakdown of a penny spare part called a “loop”. It is not difficult to fix it, but skill and experience are needed. This process can be divided into the following stages:

  • Disassemble iPhone, remove or disconnect battery.
  • Pull out the speaker and the connector that serves to fix the headset.
  • Expand the key called “Home” into parts, sequentially unscrewing the screws.
  • If there are traces of corrosion on the parts that come into contact with the train, then we carefully clean this place. A cotton swab dipped in an alcohol solution is suitable for this.
  • Install parts back.
  • Turn on iPhone and check the proximity sensor. works or not.

Remember that the train is very fragile and can be damaged by just one careless movement. Therefore, if you decide to fix it yourself, then do it carefully, without using sharp and cutting objects.
