If you are using your Galaxy S5 and the time comes when you want to use the camera, if it shows you the error message "the camera has failed" or "the camera application does not respond", from that moment the camera becomes unusable. Samsung has detected that error and as announced in a statement, those who have this problem, should contact technical service SAT of the Samsung brand or go to the store where they bought the android phone, where they should check the failure and once confirmed, repair or even provide another new Galaxy S5. This failure seems limited to Galaxy S5 in the United States, specifically the Verizon company, but the same problem can occur in other countries, so if you have had to deal with this error, you can do what was mentioned above.
