Google might be rolling out the Android 4.4.3, KitKat software update to correct an issue with the Nexus 5 that arose after the previous upgrade.
The problem stems from applications running in the background that are continually trying to access the handset's camera application. Skype tries to access the camera regularly from its background service which is the number one trigger for this bug.
Nexus 5 owners seemed to notice this once they updated their handsets to Android 4.4.2. Google recently stated that it is preparing a fix as the issue has been made known on the company's issue tracking forum. It might come in the form of Android 4.4.3.
The only real solution to the problem at this time is to reboot the device. Uninstalling third-party apps also might help.
Google launched the Nexus 5 at the end of last year. Specifications on the device include a Qualcomm Snapdragon 800 MSM8974 processor running at up to 2.3GHz, a 4.96-inch LCD 1080p display, 2GB RAM, Adreno 330 GPU, 16 or 32GB internal memory, a 2300 mAh battery and an 8-megapixel camera with Optical Image Stabilization. It is also one of the first devices to run Google's latest Android 4.4 KitKat operating system.
The device is the successor to the wildly popular Nexus 4 and could be the last smartphone of its kind as Google plans to shift directions this year by focusing on its Google Play models of other companies' flagships and discontinuing its own line of handsets. The company also recently launched a red version of the handset in its online store.
However, nothing has been finalized at this time and Google could change its mind and release more Nexus tablets or smartphones in 2014.
