1. Delete data cache and the camera application:
Access the Settings menu, and within this, the Application Manager section. Search the camera application, access to this and click the Force stop button. Then click on the Clear data and Clear cache buttons. Then restart your device. When you do are erased data and app cache camera so it may have lost some configuration preferences.
2. Factory data reset:
If the first option will not run, then you can always try to do a hard reset, but before that remember having made a backup copy of all information stored in the terminal before. You can do it by accessing the Backup Settings menu or manually by the recovery menu.
3. Wipe cache partition:
This is not possible in all smartphones. To perform this action, follow these steps:
Turn off your device and turn it on while pressing Volume Up + Home + Power on or off.
Stop press on and continue to press the other two.
You should enter the Recovery menu or recovery Android.
Use the volume buttons to select wipe cache partition and the power to select.
That is all. If anyone knows an alternative solution I invite you to share it with us.
A greeting!
