Mobile devices from Apple models 4, 4S5, 5S, 5C, 6, 6 Plus are used not only for conversations. They are multifunctional and allow the user to take videos and photographs. The small size of iPhone allows you to step into the world of photography, capturing moments of nature or family that might be missed if you don't have a camera.

It is very unpleasant when a favorite thing or certain of its functions fails, especially if you use them quite often. And when the iPhone flash does not work or is constantly on, the owner immediately wonders what to do to fix this problem. Most often this happens due to moisture penetration into the device. And we recommend that anyone who encounters a breakdown immediately contact our APPLE-SAPPHIRE service center for free diagnostics and high-quality repair of the device. The longer you delay, the more difficult it will be to repair your smartphone (and the cost of repair will increase significantly).

Do you often use your iPhone to capture unexpected moments? And suddenly your flash stopped working? Have you tried various manipulations (deleting folders, resetting factory settings), but nothing helped?

Is it possible to make a flash on an iPhone yourself?

You can check the operation of the camera by replacing it with another one. And if this does not help, then most likely the problem lies in its control circuits. Eliminating it is somewhat more difficult and cannot be done without the help of a professional. Moreover, replacing the camera requires the necessary knowledge. But still, you can perform some actions on your own.

As noted above, the main reasons for the failure of the flash on a smartphone are related to mechanical impact: moisture or shock. But the breakdown may be caused by errors in the firmware or a software glitch. Depending on this, the problem is solved in different ways.

How to determine why the iPhone flash does not work and what to do?

First of all, you should check the operation of the system. If the flash on your iPhone does not work and the cause is software errors, then you will not need complex repairs. To do this, just restart the device by holding down the Home and Power keys. Even if the flash does not start working after a reboot, do not worry, because you can try flashing it by returning the old one or restoring a new operating system.

But do not forget that changing the firmware has one significant drawback. This is often accompanied by the loss of all data and does not guarantee that the problem with the flash will be resolved. If you cannot afford to risk information, we recommend that you conduct a free diagnosis in our company APPLE-SAPPHIRE. The experts will pinpoint the reason why the iPhone flash does not work, as well as effective solutions.

After checking the gadget and identifying the causes of the breakdown, the technicians will estimate the cost and timing of repairs. Depending on the scale and complexity of the problem, repairs can take from 30 minutes to 3 days.

Photo instructions for repairing an LED flashlight. Photos are clickable.

Any electrical device can break down. This also applies to LED lights.
The online store provides a guarantee of up to 3 months on everything.

All lanterns are checked upon receipt and again upon sale.
In most cases, flashlight repair is quite accessible to an ordinary person with a standard set of tools.

In 90% of cases, all breakdowns occur due to poor contact in the flashlight circuit.

Problem 1. The LED flashlight does not turn on or flickers during operation

As a rule, this is the cause of poor contact. The easiest way to treat it is to tighten all the threads tightly.
If the flashlight doesn't work at all, start by checking the battery. It may be discharged or damaged.

Unscrew the back cover of the flashlight and use a screwdriver to connect the housing to the negative terminal of the battery. If the flashlight lights up, then the problem is in the module with the button.

.

90% of the buttons of all LED lights are made according to the same scheme:
The button body is made of aluminum with a thread, a rubber cap is inserted there, then the button module itself and a pressure ring for contact with the body.

The problem is most often solved by a loose clamping ring.
To fix this problem, just find round pliers with thin tips or thin scissors that need to be inserted into the holes, as in the photo, and turned clockwise.

If the ring moves, the problem is fixed. If the ring stays in place, then the problem lies in the contact of the button module with the body. Unscrew the clamping ring counterclockwise and pull the button module out.
Poor contact often occurs due to oxidation of the aluminum surface of the ring or border on the printed circuit board (indicated by arrows)
Simply wipe these surfaces with alcohol and functionality will be restored.

Button modules are different. Some have contact through the printed circuit board, others have contact through the side petals to the flashlight body.
Just bend this petal to the side so that the contact is tighter.
Alternatively, you can make a solder from tin so that the surface is thicker and the contact is pressed better.
All LED lights are basically the same

The plus goes through the positive contact of the battery to the center of the LED module.
The negative goes through the body and is closed with a button.

It would be a good idea to check the tightness of the LED module inside the housing. This is also a common problem with LED lights.

Using round nose pliers or pliers, rotate the module clockwise until it stops. Be careful, it is easy to damage the LED at this point.

These actions should be quite enough to restore the functionality of the LED flashlight.

It’s worse when the flashlight works and the modes are switched, but the beam is very dim, or the flashlight doesn’t work at all and there’s a burning smell inside.

Problem 2. The flashlight works fine, but is dim or does not work at all and there is a burning smell inside

Most likely the driver has failed.
The driver is an electronic circuit on transistors that controls the flashlight modes and is also responsible for a constant voltage level, regardless of battery discharge.

You need to unsolder the burnt driver and solder in a new driver, or connect the LED directly to the battery. In this case, you lose all modes and are left only with the maximum one.

Sometimes (much less often) the LED fails.
You can check this very simply. Apply a voltage of 4.2 V/ to the contact pads of the LED. The main thing is not to confuse the polarity. If the LED lights up brightly, then the driver has failed, if vice versa, then you need to order a new LED.

Unscrew the module with the LED from the housing.
Modules vary, but as a rule, they are made of copper or brass and are unscrewed counterclockwise. Unsolder the wires from the star with the LED and remove the driver.

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.

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! Do not check the “Delete user data from internal memory” checkbox.

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.

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.

1. Open the gadget settings, go to the “Reset and Recovery” menu.
2. Click "Erase all data and set settings to default."
3. Enter your Google account information and confirm the selected action.
4. 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.

Conclusion

If the camera backlight stops working on your Android phone, make sure that there are no applications installed on the system that conflict with the camera, and that the battery charge is more than 10%. Do not abuse the backlight as a “reminder”, and contact a service center to repair hardware faults.

I have already been asked why the flash does not work on Honor 10, Honor 9 Light, Honor 7a, Samsung A5, Meizu M5, Huawei P20, Xiaomi, Xiaomi, Redmi 4 phones, and in many cases it turned out that it was simply not turned on.

Therefore, first I will describe why the flash does not work in the camera when taking photos on an Android phone, and then how to turn it on when taking photographs.

A flash is the same as a flashlight - if the flashlight works, then, as a rule, the flash should work.

If it doesn’t work, then it’s either a firmware failure or a component failure - the first reason is usually solved quickly and independently.

On an Android phone the flash does not work when taking photos due to a software glitch

Not everyone knows that you can connect an external flash to an Android phone, and it’s unlikely that many will want to bother with it.

But those who really often use flash when taking photographs will not regret it.

Why? Because the external one is many times more effective than the standard one - the photos there are much better, and the shooting range is much greater.

However, I got a little carried away, let’s get back to the point and launch safe mode to check the flash’s functionality.

How to launch it If the Android phone is in safe mode and the flash is working, then the malfunction may be caused by third-party applications.

Another way to bring the flash back to life is to restore the default settings in the camera program itself.

The simplest solution if the flash on your Android phone does not work when taking photographs

Such a non-working software state of the flash during photography can be cured instantly. Open “Settings” and look for the reset function.

Where is it? It depends little on the phone model - more on the version of Android. Right now I have a Samsung phone with Android 7.0 in my hands.

You don’t need to search for long in it: “Settings”, “General settings” and you find yourself in the reset section (at the very bottom).

Just no need to be naughty. First, save the data that is important to you - it will be deleted. A full backup will not work here - then the old firmware will be restored and the flash will not work again

If you have synchronization enabled, then all data should be restored. If you choose this option, then before resetting, I recommend making sure that Google really synchronized everything.

To do this, you need to visit the Google website (or the phone developer - many also offer their own synchronization) and see if everything is in place.

There are also computer programs that can quickly transfer your files to your computer or laptop.

How to turn on the flash on an Android phone

Turning on the flash on an Android phone is quite simple and there is almost no difference between which phone and which Android.

The camera is turned on directly in the program - most often at the very top, but it can also be at the bottom.

There are three icon positions at the top of the screen. Yellow lightning bolt, crossed out icon and just white - choose the latter option.

However, everything is accompanied by text notifications for two or three seconds, so it’s almost impossible to make a mistake.

A few years ago, a phone camera equipped with a flash was the object of desire for every mobile photography enthusiast.

Now it is on almost all phones, but it doesn’t have much effect. This is a diode that supports autofocus.

Only manufacturers are trying to improve the lighting conditions of the frame, and LEDs cannot be compared to traditional flash.

The downside is the need for a large capacitor, which simply doesn't exist in thin smartphones.

Thanks to the latest invention by Professor Lee Pui-Zee, it can now become many times more effective.

She succeeded in creating a flat capacitor made of polymers that stores the charge needed to illuminate a gas just 1 mm thick.

Manufacturers now have one final challenge: implementing a new solution for mass production.

According to Jack Tuyen, CEO of Xenon Technologies, such subtle elements could appear on smartphones as early as next year.

It is very likely that the new development will arouse interest among leading manufacturers, and in the future this type of solution will appear in new models. Good luck.

Android smartphones do not have a flashlight, in the usual sense. At the same time, mobile devices are equipped with LED flashes, and some models contain two, three or more LEDs. Such equipment is perfect for illumination in conditions where there is no light. You will learn how to use a flash as a flashlight in this article.

Method 1: Button in the Quick Launch menu

Many manufacturers integrate the flashlight function directly into the system. To do this, open the notification bar and find the corresponding button on the Quick Launch panel. If the button is missing, use other methods.

Method 2: Widget

Some applications, such as HD Widgets, allow you to customize a panel with a flashlight activation button.

Method 3: Gesture

Most Motorola smartphones support the Chopping Gesture feature. A double swipe allows you to activate or deactivate the flashlight.

If your device supports gesture control by drawing a gesture on the screen, visit the settings and check whether the flashlight can be activated.

Method 4: Application

If the above methods do not work or are not suitable, then use the flashlight application. The option with an installed program is interesting because of its prostate or additional functionality, for example, two modes with the intensity of the glow or several variations of blinking. To download, open and select your preferred program.

Conclusion

To turn on the flashlight on your Android phone, use any of the 4 methods described. Although the use of LED flashes will not replace a full-fledged flashlight, since the LED backlight is not designed for long-term operation, it is enough for many tasks. Remember that during operation the flash becomes noticeably warm, and if it overheats, it turns off temporarily. Flash in flashlight mode is useful when you need to briefly illuminate the road or illuminate a room.
