Google is currently testing Android 4.4.3, KitKat and will roll out the software to popular smartphones such as the Galaxy S5, Galaxy S4, Nexus 5 and HTC One soon.
This will be a minor update that will fix a camera issue found on Android 4.4.2 that over uses the CPU when the camera app is operational. This makes the device lag and drains the battery.
Information on the new firmware comes from LlabTooFeR's Twitter account.
"Android 4.4.3 is under testing. Build number is KTU72B. Probably it will fix known camera bug," wrote the site.
There are no other details available at this time regarding what new features the update will bring. It will probably be released with a different build number.
The camera 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 will probably 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 released Android 4.4 on the Nexus 5 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.
