Press Recent Applications .
Browse application overviews to access different applications.

If you see multiple applications running, press Clear All to close all at the same time.

After clearing camera and background apps, restart the Camera app, and check to see if it works fine this time. If it still fails and invites the same camera warning, continue to troubleshoot more complex software problems on the phone.

Second solution: software reset / reboot your phone.

Another simple solution you can try is a soft reset or device reboot. This will help you eliminate minor software errors that cause random application issues, including those that affect the phone's camera application. Here's how to reset HTC U12 / U12 Plus:

Press and hold the power button for a few seconds.

These two methods do not affect the data stored on the phone, so creating backups will not be necessary.

Third solution: clear the cache and data from the application.

Caches are temporary files stored on each application or telephone system. These files are essential for multitasking as when switching from one application to the other. However, having more applications in the background can also cause conflict, especially when one of them is corrupt or becomes dangerous. To clear this problem, erase the cache and camera app data from your phone as follows:

If necessary, tap View all applications.

Software updates can also be the key to solving a device problem caused by malware and software bugs. This is probably the cause if the application of the device suddenly stops after downloading the image files and stores it in the Gallery folder. The installation of the latest software update on your device can therefore solve the problem because it usually offers correction fixes to eliminate and fix errors that may cause failure or instability of l & # 39; application. Update your HTC U12 / U12 Plus:

Press Update Center then Update the system.
Press the option for Check for updates.

An update notification will appear on the screen if a new system update is to be retrieved. Before downloading the update, make sure your phone has enough RAM or internal memory space and that the battery life should be at least 50%.

Then follow the on-screen prompts to start downloading and installing the new update.

Fifth solution: erase the cache partition on your phone.

Software-related errors, including those that cause problems with the camera application, can also be resolved by clearing the phone's cache partition. Temporary files stored as cache on system folders, including those that have been corrupted, will be erased, which will prevent the system from containing errors and will be ready for another reboot. Here's how to perform a factory reset / reset:

Other Options

The initialization of the phone in safe mode can also be considered as an option to determine if the problem is due to third-party applications or not. It is also worthwhile to perform a general reset if the camera warning persists and your HTC U12 / U12 Plus camera still does not work after making all applicable alternatives and possible solutions.
