Google Nexus 5 could be Nexus 4 2 equipped with new and upgraded specs and features.

Google's smartphone may follow the footsteps of its brother, the Nexus 7, which recently released an upgraded version and included new cameras, better screen displays and speakers as well as a lighter and thinner build. This may also be the case for the Nexus 4.

Thus, we can expect a Nexus 4 2 on the way. The upgraded specs and features of the smartphones could be the latest 4.3 version of the Jelly Bean OS or the rumoured 5.0 version of Android operating system dubbed as Key Lime Pie.

The handset may also include a larger screen display, bigger internal storage, better camera and 4G/LTE, which are all missing in the previous Nexus 4 smartphone.

If the aforementioned Nexus 4 2 specs and features prove to be true, consumers may expect a release date to happen sometime around September or October along with the Nexus 10 2. Naturally, these will be the first devices to get the Android 5.0 Key Lime Pie upgrade.

Rumours claimed that the Google Nexus 5 will include a 5-inch Full HD screen display; an eight-core processor clocked at 2.3GHz paired with 3GB of LPDDR3 RAM; 13MP rear camera; 3300mAh battery capacity and the latest Android OS. The handset is rumoured to be available in 16GB, 32GB and 64GB variants and will support 4G/LTE connectivity, which was missing in the Nexus 4.

Last week, an insider confirmed that Google Nexus 5 will happen later this year and Motorola is working on the device.

Insider Taylor Wimberly said that Motorla is currently working on the Google Nexus 5 release date. In his Google+ account, he confirmed that Motorola is working on a Nexus smartphone. The post does not include many details but it is enough to make waiting consumers excited.

"Motorola will release a Nexus smartphone in Q4 (that is not the Moto X)," he posted on his account. Wimberly gained a good reputation after his predictions for the upcoming Moto X proved to be accurate.

However, Google has not confirmed yet which company it will partner with in making the Google Nexus 5.
