My gf has exactly the same problem. I'm gonna try the following steps:
- You might find that a simple restart does the trick. Hold down the Power button and select the Restart option. The problem may return.
- Try going to Settings > Application manager and select the camera app. Tap on Force stop, Clear cache, and Clear data.
- Try clearing the cache partition. Hold the power button and choose Power off then press and hold the Volume up key, the Home button, and the Power button. When the phone vibrates, release the Power button, but keep holding the other two. When you see the Android System Recovery screen you can let go. Use Volume down to choose wipe cache partition and press Power to select it then, when it’s done, press Power again to Reboot System Now.
- There’s a chance that an app is causing the problem. Any app that uses camera functions, including flashlight apps, could be the culprit. The fast way to check this is to reboot in safe mode. Hold down the power button and select Power off then hold down the power button to turn it on again and when you see the Samsung screen come up, release the power button and press and hold the Volume down key. You’ll know it worked if it says Safe mode in the bottom left corner. If the camera works then it’s definitely a problem with an app you installed. Hold down the power button and choose Restart to get back out of Safe mode.
- If you’re using a microSD card to save photos try removing it, save them elsewhere, and see if that makes a difference.
- Back up anything important and try a factory reset via Settings > Backup and reset > Factory data reset.
Have you solved the problem yet?
I did clear the cache and I switched to internal storage. Also I uninstalled Google' camera app, which I thought would be neat but never used after 1st launch; it seems a little faster but I'll have to use it a few days to see. It may be my SD, as it is pretty old.
Safe Mode didn't effect any change.
I'd never tried to enter recovery on this phone and inadvertently entered Download mode instead. I blame my overly large fingers for it. Gave myself a moment of concern as I only see DL mode when I first root a device, almost 2 years ago for my last phone. I'd forgotten that the "DO NOT TURN OFF TARGET" warning didn't mean much without Odin running.
If this isn't an indicator of a upcoming camera issue I'm not too worried about the lag, if it fails it has a warranty....
It may or may not be related to this...

If it continues, exchange it for another S5.
Yeah.. I mentioned that in OP. That problem usually presents as a "Camera has failed" message according to articles, there is no reference to any symptoms prior to failure.
