Why does the camera not work on my Android phone / smartphone? What to do?

Modern smartphones can boast of two cameras at once – the rear (main) and front. The front is used primarily for selfies and video calls, and the rear is used for everything else. Some smartphones have camera modules that can give odds to cameras. But no matter how the module is installed in the smartphone, the camera may stop working. Fortunately, in most cases this is easy to fix, but not always. Let’s go in order.

Software crash

In this case, it means a certain malfunction that occurred in the firmware, as a result of which the camera may not work or, say, show a black screen. The first thing a user needs to do is restart his smartphone – this simplest procedure helps to cope with a huge number of all kinds of errors and problems that occur in mobile devices..

Application incompatibility

We are going up. Remember which applications you could install recently. Perhaps they conflict with the camera application. This is especially true in cases where you decide to use a replacement standard camera application.

What to do? You need to find the source of the problem, and you can do this by uninstalling applications installed for a certain period of time.

Check your device for viruses and trojans

Alas, for the Android operating system, there are a huge number of viruses, trojans and other malware. The most interesting thing is that in many cases the user himself is to blame for the infection of the device – just install the application from a third-party source (not from the Play Market), which contains a malicious file.

So, viruses can affect the operation of the camera. In this case, it is worth using an antivirus, fortunately, their choice in the same Play Market is large enough, in addition, most of these applications can be downloaded completely free.

Update firmware and install new firmware

If you updated the firmware version, after which the camera stopped working, it is either the firmware itself or that something went wrong during the upgrade. In the first case, you must wait for the manufacturer to update the software, and in the second, install the firmware again, but on your own.

If you install custom firmware, it is not surprising that the camera does not work, because the most stable firmware is stock, that is, from the manufacturers. Various ports and custom systems often have many disadvantages. Here you must either reconcile, or roll back to the factory firmware.

Flush cache

In this case, the camera will work, however, it may not save pictures or will not allow to take pictures at all. In such a situation, it is worth clearing the cache. How to do this, our site has already told, and more than once.

Incorrect settings for saving photos

Another thing may be in the incorrect settings for saving files. As you know, on smartphones you can choose where photos and videos will be saved – to the device’s memory, or to a USB flash drive, if any. Accordingly, if a USB flash drive is specified in the settings, but it was removed, there may be problems with saving files, although the system in this case should automatically select the available device memory for storing images. Usually in such situations, the camera works, but does not allow you to take pictures.


If the problem is some kind of software failure and you are sure of it, but there is nothing you can do, in extreme cases, reset the settings (Hard Reset).

Wipe the camera peephole

If you see strange noises on the display when starting the camera, first wipe the camera’s eye – it’s probably just got dirty. In some smartphones, the camera module is able to pass dust; in this case, how many do not wipe the lens, you will not change anything, only replacing the module will help.

Module mechanical damage

Much worse if the matter is mechanical damage to the module. It is enough to drop the smartphone once to disable the camera module, and in this case, as you know, only its replacement will help. Even if the smartphone is under warranty, replacement is at the expense of the owner – warranty obligations for problems caused by mechanical exposure do not apply.
