Warning: Camera Failed!
This problem occurs without apparent reason. We've received several emails from our readers who have encountered this problem. One owner said he only had the phone for two days and it was his first time to use the 13-megapixel camera of his device when this error message greeted him.
I asked one of my friends, an Android developer who is building custom ROMs for new Android devices, about this issue. While he said he didn't encounter the problem, it could be just a corrupt camera app data or a conflict between the software and the hardware. The following procedures are said to solve the problem, according to him:
Clear Camera App
1. From the Home screen, tap Menu.
2. Choose Settings.
3. Tap Applications Manager.
4. Swipe to choose All tab.
5. Choose Camera.
6. Tap Force Stop button.
7. Tap Clear Data button.
8. Reboot the phone.
Now, see if the camera works after this procedure. Otherwise, continue with the other procedures.
Wipe Cache Partition
For people who are familiar with Android's infrastructure, it is normal for them to suggest to wipe the partition cache. This procedure will not delete saved personal data only the ones that are commonly used by the system.
1. Turn the phone off.
2. Press and hold the Volume Up, Home and Power buttons until the phone vibrates.
3. Let go of the Power button but continue holding the Volume Up and Home buttons until Android System Recovery screen appears.
4. Press the Volume Down button to choose 'wipe cache partition'.
5. Press the Power key to select.
Once the partition cache was wiped out, the phone will automatically restart. See if the problem was solved after this.
Factory Reset Your Phone
I know it's a noob suggestion especially for new units. But according to the developer, this problem might occur if the phone was improperly setup. Thus, it would be wise to factory reset the Galaxy S4 if it starts to manifest this problem. Here's how to do a factory reset on your Galaxy S4.
NOTE: Before doing this procedure, make backups of your important data and files.
1. From the Home screen, tap the Menu button.
2. Choose Settings.
3. Tap on Accounts tab and choose Backup and Reset.
4. Tap Factory Data Reset.
5. Tap Reset Device.
6. Touch Delete All.
A factory reset could fix a lot of problems including inconsistencies between the software and the hardware. In case the problem wouldn't be resolved after this, there is no other option left but to claim a replacement unit.
Contact your provider, explain the problem, have the tech verify it and request a replacement unit.
