The camera on my dexp phone doesn't work. What to do if you couldn’t connect to the camera on Android
" on Samsung Galaxy S4, don't panic because this is usually not a critical error and has a simple solution. In most cases, this is more of a software glitch than a hardware glitch. In principle, we suggest you try simple steps to fix this problem, going from simple to complex:
There are at least three things you can do yourself, without the help of a professional, without fear of consequences, to try to solve this problem.
Clear cache and camera data
- From the Home screen, press the Menu key.
- Select Settings.
- Find Application Manager.
- Swipe left twice to select the All tab.
- Highlight and click Camera.
- Click the Stop button
- Next Clear cache.
- Click Clear data. (Please note that all your settings will be deleted)
- Reboot your phone.
- Check if the camera is working
A camera failure may be caused by corrupted data in the cache, which we clear. Clicking the Stop button will close the application. The Clear cache button deletes all files used by the application at startup, and the Clear data button will delete all user settings. This procedure will not affect other applications.
Clear cache and gallery data
Follow the same procedure by finding Gallery in the apps. The gallery and camera are closely connected and work side by side. The camera app takes the photo, but the gallery manages those photos: it includes crops, thumbnails, sorting images by name (or date or size, or whatever), cloud syncing, etc. In short, the Gallery app has a lot of things it does through the camera. That's why it's only logical to clear the cache and data whenever the camera stops functioning normally.
Factory Reset / reset to factory settings
If the previous methods did not work, let's try resetting the entire phone to factory settings.
Attention, all your data, including applications, credentials, music, pictures, etc., will be deleted. It is advisable to back up your data
- Menu.
- Select Settings.
- Accounts and select Backup & reset.
- Click Reset device.
- Read carefully and confirm
This procedure will delete all files, settings and data, however, there are certain folders and sections in the phone memory that cannot be deleted, the best example is the cache memory partition
Cleaning the cache memory section
- Turn off your phone.
- Press and hold the Volume Up, Home and Power buttons until the phone vibrates.
- Release the power button, but continue to hold the volume up and home rockers until the Android System Recovery screen appears.
- Press the Volume Down button to select wipe cache partition.
- Press the Power button to select.
- To exit the mode, select “Reboot system now”.
If you did everything according to the instructions, but the recovery mode does not start, remove the battery for a short time, insert it and try again.
Update errors
Another cause of the problem may be a buggy operating system. If you recently updated your Android version and noticed the notorious camera glitch, then the problem is most likely caused by the update. It is necessary to roll back to a more stable version.
If you did everything correctly, but the camera still reports a failure, you need to show your smartphone to a specialist from the service center; perhaps the camera is broken physically, not software. Thank you for your attention.

Modern smartphones provide their users not only with numerous capabilities comparable to those of a computer, but also with various problems. These include lags, common errors and glitches that can make working with a smartphone unbearable. Fortunately, all of them can be fixed quite easily and the problem with connecting to the camera is no exception. It is only important to know how to eliminate such an error.
What is this error?
A similar malfunction, in which a user who decides to use the smartphone’s camera is shown a message: “could not connect to the camera on Android,” has been encountered by many users lately. At the same time, the number of owners of gadgets on this operating system who have reported the presence of such an error is constantly growing.
The problem itself, oddly enough, does not have a guaranteed solution, since the process of troubleshooting depends solely on the cause of its occurrence. The difficulty is that, as a rule, it is not possible to identify them. This makes solving the problem somewhat more difficult, but does not prevent it at all.
Elimination methods
Since this problem occurs very often and can be caused by a huge number of reasons, in most cases you need to try all the methods listed below in turn to completely eliminate it.
- A reboot, which sometimes needs to be done several times in a row, can restore the functionality of the smartphone camera. In some cases, you may need to enable/disable the gadget, however, this method does not help everyone.

It is possible that the system program has been damaged, and such a replacement will allow you to use the camera as usual. As practice shows, after all these manipulations, the device begins to function normally.
However, if the problem cannot be resolved, it makes sense to clear the cache, reset the settings, or even reflash the smartphone.
It all starts with the fact that when you try to use the camera on your Android device, you first see a blank screen with a camera icon in the center, and then you receive the message “Could not connect to the camera.” Sometimes it is possible to use the camera after rebooting the device, but, as a rule, the frequency of the error increases, and soon it becomes simply impossible to use the photo module to take a couple of photos. Many users also complain that they receive a similar error message when trying to shoot video at the minimum resolution (240p). Is it possible to somehow improve the situation? Let's try to figure out what's happening together and find accessible ways to independently solve the problem.
1. Available methods
Users report that the camera starts working after rebooting the Android device. Sometimes you have to reboot the gadget several times to achieve the desired result. In any case, it makes sense to try this elementary method - turn off and turn on your smartphone or tablet again.
Every Android device has a boot into "Safe Mode" feature, meaning you reboot the phone and turn it on, activating only essential apps and a limited number of available features. Safe Mode is great for troubleshooting, as downloaded applications will be disabled and you will be able to determine whether there is indeed a conflict between various third party software and system software related to the use of the camera.
To restart in safe mode:
If the camera works normally in safe mode, then you have narrowed down the search for the causes of the error. The problem is a conflict between third-party applications and system software. It is because of them that you cannot connect to the camera. Your next steps:
C) Remove conflicting third-party applications
Try uninstalling third-party applications related to the camera. These are applications that can take pictures during their operation. For example: Snapchat, Whatsapp, etc. Surely there are programs on your smartphone or tablet with which you can take photos directly from the application and share them. Remove such programs sequentially, one after another, checking after each removal to see if the error has disappeared. If you were able to connect to the camera, you have found a third-party application conflicting with the system software. And one more thing: do not forget to switch between video, panoramic shooting and other modes during the test - the problem can appear in any of them, and it is important for us to restore the full functionality of the camera.
D) Try using a third party camera app
If the system app is the only program that has access to the camera on your Android device, and you receive the “Unable to connect to the camera” message, you might want to try using a third-party app to access it. The Google Play store offers many programs suitable for this purpose. Use the search function to find apps in the Camera category. Choose one of the popular applications - such as: Candy Camera, Open Camera, Camera 360, Camera MX or Camera for Android. Download and install the application, launch it.
If you managed to launch the camera from a third-party application downloaded from Google Play, then the problem lies in the official system application for it. Try the following:
2. Medium difficulty methods
These are the standard steps that you can take when the app shows the error message “Failed to connect to camera”. Try using them all - it should help. And don’t forget to stop the application and restart it before each new attempt to connect the camera. The methods given here to fix the “Unable to connect to the camera” error do not carry the risk of losing saved photos and videos.
A) Clear cache and data
B) Uninstalling and reinstalling updates
Go to the same camera app settings as shown above. If there is an option to remove updates, do so. But remember that you should not use old versions of the apps, so you will have to visit the Play Store to update the camera app again.
B) Check permissions (Android Marshm only)
Android Marshmallow has a personalized system for allowing access to major applications. You must confirm that your camera app has permission to access the camera. Typically, if the required permission is missing, it is requested during application startup.
- Go to "Settings" -> "Applications" -> "Cameras".
- Click on "Permissions".
- Make sure the Camera Resolution slider is moved to the right. You can turn it off and on again.
3. Error resolution methods for advanced users
Attention: These methods to fix the error “Couldn’t connect to the camera” when used will result in the loss of data saved on the Android device. To avoid losing contacts, photo galleries, games, music and other content, you need to perform a backup. Back up your photos, account information, and apps to your Google Account. All this will be re-installed after adding the same Google account to the device.
A) Clearing cache
This action allows you to clear the device system of temporary data - outdated and only cluttering up the memory. This option is activated in Recovery mode, which becomes available after rebooting the phone using the bootloader.
To clear the cache, follow these steps:
Once clearing cache is completed successfully, restart your phone and try launching the camera app again. Please note that your Android device may have a different button combination for accessing maintenance and repair mode.
B) Reset to factory settings
Resetting settings is considered the most drastic way to solve problems, as it entails complete loss of data. But if no other methods help, then you will simply be forced to use it. However, backup will help you save your data, and re-configuring the device will only strengthen your skills in working with Android devices. Here are two ways you can use to reset your phone or tablet to factory settings.
Method I: From the recovery menu
Method II: From System Settings
If none of these methods worked, then the problem most likely lies in the hardware of your Android device. You can return the phone or tablet back to the seller if the warranty period has not yet expired. Otherwise, you will have to contact the authorized service center of the gadget manufacturer or choose a repair shop with a good reputation, whose specialists will be able to understand the malfunction of the device. However, if you are not sure that the cause of the “Unable to connect to the camera” error does not depend on the hardware, then you can wait for the next operating system update. Sometimes after updating some problems resolve themselves. The only pity is that this happens extremely rarely.
