A certified Nexus 7 tablet with the Android 4.3 update recently appeared at the Bluetooth Special Interest Group (SIG) web site listing. It has not been clarified though if the tablet on the listing is the second-generation Nexus 7 or the existing tablet being tested on the much awaited new Android operating system.

Taiwanese company Elan Microelectronics has reportedly started shipping a week ago the touch screen controller ICs for the enhanced Nexus 7 that will be available in the coming months with July as the earliest arrival. The report corroborates with Google's possible plan of launching the Android 4.3 update on the upgraded tablet this summer.

The certification on FCC or Bluetooth SIG could be an indication that a new device's release date is coming soon so there is still a chance that the new Nexus 7 tablet will arrive with the Android 4.3 update. Features and specs for the new Nexus 7 are still unidentified.

Some reports are claiming that the Qualcomm Snapdragon 600 SoC has been utilized on the new Google tablet replacing the quad-core Tegra 3 processor. The 28nm chip has four Krait 300 CPU cores clocked up to 1.9 GHz, an Adreno 320 Graphics Processing Unite (GPU) core with built-in dual-band Wireless AC and Bluetooth 4.0.

Other reports suggest the second-gen Nexus 7 will be equipped with the Qualcomm Snapdragon S4 Pro SoC which is a 28nm chip that has two or four Krait CPU cores clocked up to 1.7 GHz and the Adreno 320 GPU with support for 1080P video recording. Additional features include the dual-band Wireless N and Bluetooth 4.0, camera support up to 20MP and 3G/4G World/multimode LTE on select chips capability.

The new Nexus 7 is expected as well to have a 1920x1200p resolution on screen display that uses the LTPS technology, the power of a 4000mAh battery, 5MP rear-facing camera and 2MP front-facing camera.
