It’s only been a few days since Google kicked off the rollout of the Android 5.0 Lollipop update and the major bug has just been found in both Nexus 5 and 4 versions of the upgrade.

Although Google has been testing the Lollipop build for a few months at least, it looks like they missed one annoying bug affecting both Nexus 5 and 4 cameras.

As much as the search giant would like to offer users a bug-free update, it seems that internal testing is never enough when put against the huge number of people who will be using the update in day-to-day circumstances.

There’s no point in comparing Google’s testing and the actual release version which was tested by a lot more users. Even though the Android 5.0 Lollipop does come with a bug, what matters is how fast Google will be able to patch it.

Until then though, let’s see how it affects the Nexus 5 and 4 smartphones. First of all, keep in mind that this issue only affects those devices already running Android 5.0 Lollipop.

Secondly, the bug won’t trigger unless you decide to take advantage of the flashlight function that’s been placed in the Quick settings menu.

Most, if not all, Nexus 5 units seem to be affected by this flashlight bug, which basically disables the phone’s camera. If you turn on the flashlight and leave it open until it automatically turns itself off after a while, and then try to open the camera, you will notice that the shutter won’t open anymore.

In order to start using the Nexus 5’s camera after you get an error message, you will have to reboot the smartphone. The flashlight won’t work either until you reboot the smartphone, so make sure you don’t turn it on and leave it open.

You won't have to reboot the Nexus 4 to re-enable the use of the camera

Nexus 4 smartphones seem to have been hit slightly less by the flashlight issue, in the fact that you won’t have to reboot your handset in order to make the camera work again.

However, it you leave the flashlight open until it turns itself off, the camera will be disabled. The good news is that opening the camera from the shortcut on the lock screen will enable the camera once again, so you won’t have to reboot the smartphone anymore.

We suspect Google has already acknowledged the issue by now and is already working on a fix, but there aren’t any details on the matter yet. Stay tuned for more info on the subject.
