Why doesn't the flashlight turn on?

On Android smartphones, the flashlight located in the camera module is used to operate the flashlight. It may stop working due to a system failure or mechanical damage. Possible causes and solutions to the problem:

On some smartphones, the flashlight does not work because the battery charge is too low (usually 10%). In order for it to turn on and in power saving mode, you need to get root rights (superuser).
If the flashlight stops working after flashing or installing drivers, then the failure may be systemic in nature. In this case, you can try doing a factory reset.

If the flash or flashlight stops working after a fall or any other mechanical impact, you will have to contact a service center to have it repaired.

The flash or flashlight does not work on your Android phone or tablet. What to do and how to treat.

Many users encounter a problem when their Android phone or tablet starts acting up. It seems that nothing happened that could cause a malfunction, but it does not work as it should.

For example, the device experienced problems in that the system stopped supplying power to the flash LEDs . The reason for this may be:

1st: Software failure - i.e. the problem is a software glitch

2nd: Hardware failure - i.e. the problem is in the hardware (i.e., replacement or restoration of spare parts for the gadget is required)

However, do not rush to get upset - in 90% of cases with problems turning on/off the flash of a smartphone or tablet based on Android, a software glitch is to blame, which you can easily fix on your own.

Fixing a software glitch:

Method 1. Quite simple - go to “settings” , find “backup and reset” , in which you select a complete reset with all data deleted. Be careful, using this method is often effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone or tablet. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if after this the problem is not resolved, see Method 2.

Method 2.

It is based on solving problems with communication and network reception of Android phones and tablets by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a lot of them, however, the fewer functions an application contains, the more effective it is, as a rule. The best way to monitor system functions, corrects, and corrects all possible settings and synchronization errors is a small, easy-to-use, free utility for devices based on Android Multi Cleaner . You can download the application from Google Play and see its additional options in the description HERE . After installing the application, all that remains is to launch it. Further, in principle, nothing more is required from you. The application will take full control of the device's functions. (By the way, among other things, the gadget will begin to charge 20% faster, and its performance will also increase significantly, which will affect the loading speed and operation of all applications, games, and the system as a whole. On average, after scanning, the system runs at 50% faster.)

Method 3.

Changing the device software, or, as it is also called, “flashing the firmware.” This method, as a rule, requires certain skills and can be solved by contacting the Service Center. To carry out this task yourself, you need to contact the website of the manufacturer of your device, download the utilities necessary for flashing the firmware and the firmware itself, and then reinstall it on your gadget.

If none of the methods brings results, unfortunately, you will have to contact the Service Center to repair your tablet or smartphone.

The flash or flashlight does not work on your Android phone or tablet. What to do and how to treat.

Camera modules on modern smartphones are usually protected by sapphire glass. This material is scratch-resistant, but only covers the lens, other parts remain unprotected.

If the flash on your phone does not work, you should determine the nature of the problem: hardware or software. The module may stop working due to incorrect installation of drivers, incorrect firmware, or mechanical damage.

Typical faults

If the flash on your smartphone stops working, first rule out typical problems with the main board:

Short circuit resulting from liquid entering the housing. If the device is flooded with water, contact a service center, otherwise irreversible corrosion processes will critically damage the electronics.
The diode installed in the module has burned out. The reasons can be very different: from low-quality parts to voltage drops during charging.
As a result of an impact or fall, the cable from the internal board connector was disconnected.

Causes of failure

The flash may not fire in the following situations:

When you press the camera button, the module is activated, but with a delay. The result is that the photo was taken without the necessary backlight.
The flashlight works, but the backlight in the camera app does not. The cause of the breakdown is usually a software error.
The smartphone battery is discharged below 5%, and on some models - below 10%. In this case, Android disables the ability to enable the module in order to save energy.
Poor contact of the connector on the system board or damage to the connector itself. Oxidation of the loop contacts falls into this category.

Solution

First, make sure that the device's motherboard is fully functional. Remember if the phone was dropped and if liquid got into the case.

Restart your smartphone.
Try resetting the settings without deleting data.
Open the gadget settings, go to the “Backup and Reset” tab. Click Reset Settings to Defaults.

Important! Not about.

The procedure will take a few seconds. Once completed, open the camera app and check if the problem is resolved.

If your phone's battery drains quickly, causing the flash to turn off, your only option is to replace the battery. Contact a specialist to clarify the price of your smartphone's battery and the possibility of replacement.

Useful tips

Flash drivers may fail after flashing the gadget with a modified version of the OS. In this case, only a full reset to factory settings will help.

Open the gadget settings, go to the “Reset and Recovery” menu.
Click "Erase all data and set settings to default."
Enter your Google account information and confirm the selected action.
Once the process is complete, the flash should work again, unless the malfunction was caused by a hardware problem.

In some cases, system apps do not work on newly installed Android. Wait for the release of an update that corrects defects or roll back the gadget to the previous firmware version.

It is worth noting that the diode may burn out due to constant use as a notification reminder. If the flash does not fire, remove all third-party programs that can affect its functioning. Such applications include modified versions of the camera and flashlight, especially those with a strobe function.

On older versions of Android, the module can be completely disabled from the settings menu. To reactivate, go to settings, then “General”, activate the appropriate option. Open the camera application and check the functionality of the component. The check can also be performed using a flashlight; it turns on in the notification shade.

Method 3: Touch assistant

Another method of turning on the flashlight will probably be found more preferable by those users who control their Xiaomi smartphone using gestures, that is, they have disabled the touch buttons “Menu”, “Home” and “Back” in the MIUI settings, and at the same time activated the “Touch Assistant” " Like the approach described above in the article, using the “Touch Assistant” to solve the problem stated in the title of the article requires preliminary configuration.

Follow the path: “Settings” MIYUAI – “Advanced settings” – “Touch assistant”.

If this has not been done previously, enable the “Touch Assistant” by activating the corresponding switch on the screen that opens.

From the “SETTINGS” list displayed on the screen, go to the “Shortcut Functions” section. Next, select the touch assistant button that you want to replace with “Flashlight” and click on its name.

In the list of “QUICK SETTINGS” options on the screen that opens, tap “Flashlight” - this will place a checkmark to the right of the object’s name.

At this point, the setup is complete, and you can already evaluate its result - expand the touch assistant functions, now touch the “Flashlight” button among them, which instantly activates the smartphone’s flash. The LED is turned off by repeatedly tapping on the specified MIUI interface element.

Smartphones, which almost every person now has, perform hundreds of different functions, without which we cannot imagine modern life.

The telephone has long ceased to be just a means of communication - now it is: miniature portable computers, sources of information, an entertainment center placed in the hand.

One of the main advantages of smart phones is the ability to take photos and videos that can compete in quality even with material shot on professional cameras.

To do this, the phone has a lot of auxiliary effects and a flash that allows you to achieve the best quality photos even at night.

The problem of a non-working flash, which is often used as a flashlight, is often found even in flagship devices. Let's try to figure out why the flashlight on the phone doesn't work and how to fix this problem.

Method 4: Android App

If the above three features, which, by the way, can be used simultaneously, are not enough to implement your plans to use the “Flashlight” function on a Xiaomi smartphone, it makes sense to pay attention to applications from third-party developers.

Why doesn't the flashlight work?

Many people know that smartphones have an LED flash.

As practice shows, the cheaper the device, the less sense the flashlight is, since its quality leaves much to be desired.

At such moments, additional flashes that are attached to the phone and run on batteries or are separately charged from an outlet can be real saviors.

If we talk about the “native” flash of the phone, then the problem may arise due to:

errors in the software;
applications that disable the flash;
failure due to moisture on the motherboard (corrosion, which can lead to critical failures in the device);
low battery level (most devices turn off the flash function when the battery is low to save charge);
burnt-out flashlight diodes (poor quality parts or voltage drop when charging).

How to fix the problem

Before taking your phone to a service center, you can independently take steps to prevent damage to the software.

To begin with, you should reboot your smartphone.
If the problem is not resolved, let the device charge for several hours and use the flash function again.
If the flashlight previously worked well, but after downloading certain applications it stopped working, try uninstalling them.
It's worth reviewing the photography mode settings again, because some people simply forget to turn on the flash before taking pictures.

If all of the above tips did not help, all that remains is to do a full reset or reflash the device.

However, even this step will not help if the problem is inside the device. Here it is better to contact specialists who will identify flashlight problems by opening the phone and checking the contacts.

Flashlight won't turn on

There are several reasons why the flashlight does not turn on, but we will look at the most common ones and solve the problem step by step.

Enough battery?

This is one of the most common reasons, which is not a problem in itself, but is a limitation for many terminals. Many manufacturers do not allow the flashlight to be turned on when the battery is below a certain percentage , usually 15% or less. Not being able to manage every last milliamp of our battery is frustrating because if we want the battery to drain along with the flashlight because we need to use it in a certain situation, it should be our decision, not the system. In this case, we will have to charge the battery above 15% and reintroduce it.

Possible overheating

If you played for a long time before turning on the flashlight, or the mobile phone was charging, then it may have overheated . As a safety measure, many terminals prevent the flashlight from turning on in such cases. You will have to wait until the device cools down and try again.

Applications in using a flashlight

There are many apps that can use the mobile flash, including the camera app itself, which disables the flashlight feature. To see if it is a lock due to an application, we will need to open the recent applications menu and close all running ones, and check again whether the flashlight turns on correctly.

Try different ways to light up

As we discussed above, there are many different ways to turn on a flashlight . The most common is to click on the shortcut on the taskbar, but we can always turn on the flashlight using gestures, a desktop shortcut or even asking Google Assistant. Alternative methods are a good way to find out whether we are facing a specific problem or something more serious.

Instructions

The article provides instructions for Android 9.0, but the algorithm of actions is universal for any version of the operating system starting with Android 4. Let's figure out how and where to find a flashlight on Android.

Standard method

By default, the developers placed the function in the notification panel. To enter it, you need to pull the curtain at the top of the screen down. A panel will appear with quick access to some features, including a flashlight. We activate it by clicking on the icon once.

If it is not among the presented elements, drag your finger from top to bottom again. This will expand the work panel, click on the desired icon.

Add to curtain

Sometimes the standard settings and layout of functions on a smartphone may be changed. To add a flashlight to the curtain, you need to swipe down from the top of the screen twice, after which the extended panel will open. Click on the pencil icon.

A window with the change will appear. We go down and find the lantern icon, drag it up while holding your finger on the picture. It will appear in quick access.

Method 2: Button combination

The next method we are considering to turn on the flashlight on a Xiaomi smartphone, if you use this function frequently, may turn out to be more convenient than calling it from the curtain, but requires preliminary configuration.

Open the “Settings” of your smartphone by tapping on the corresponding icon on the MIUI desktop or the “Gear” icon in the quick access panel.

Follow the path “Advanced settings” - “Button functions”. On the screen that opens, in the “Functions of buttons and gestures” list, tap “Flashlight”.
A faster way to open the target screen is to enter the query “Flashlight” in the “Search Settings” field and then click on the only transition option provided by the system.

In the “BUTTONS and GESTURES” list, select the combination of touch buttons and/or hardware “Power” that suits you to turn on the smartphone’s flash and click on the inscription indicating this combination.

Make sure you select the correct method for calling the flashlight and evaluate its level of convenience by watching the animation in the PREVIEW area on the screen, and then exit MIUI Settings. From now on, you can always quickly turn on and off the flashlight by influencing the combination of buttons on your Xiaomi smartphone set for this manipulation.

Alternative way

Amateur firmware is common on Chinese smartphones; all functionality is not always fully implemented on them. In this case, you can download the application from Google Play. To do this, go to the store and enter the phrase “Flashlight” in the search. A list of products to download will appear. Such programs have a number of advantages, for example: additional settings, increasing LED brightness, SOS mode.

Using third party flashlights

Programs for activating the flashlight can be downloaded from the Google Market. Such applications are free and quite easy to use. The most common:

“LED Flashlight” is a simple, yet functional program. The camera flash or mobile phone screen is used as backlight. The application offers users three main modes. There is a timer setting to automatically turn off the light;
Tiny Flashlight is a free program that allows you not only to use standard lighting, but also to customize various sources. The application is quite simple and easy to use;
“LED Flashlight HD” is another application that stands out from the general background in that it supports not only light, but also sound components. There is also a timer function for automatic shutdown.

How to disable

How can I turn off the flashlight on my phone? It’s very simple, you just need to click on the monk in the curtain again. If for some reason it does not stop working, you should restart the device. Long-term operation of the function will speed up the process of discharging the gadget due to high energy consumption and heating.

The video explains how to enable the flashlight function on any Samsung smartphone. This method is different due to the presence of an outer shell pre-installed by the manufacturer.
