Perhaps the most anticipated Android smartphone release of the year is Google's next iteration of the Nexus series.
This year, Google is expected to release the 2nd generation of the Google Nexus 5, with the first having been released in 2013.
The 2015 Nexus 5 is expected to include many of the same features as other high end smartphones, featuring a number of significant upgrades over the first Nexus 5. The first upgrade will most certainly be the display of the device, which will likely be a 2K display in the 2015 version, over the 1080 x 1920 pixel display found in the 2013 version.
Next up is the processor. While the first generation of the device included a Qualcomm Snapdragon 800, the second will likely include a Snapdragon 810, Qualcomm's latest and greatest mobile processor. However, some rumors suggest that Google will opt for the Snapdragon 808 instead of the 810. Google will also upgrade the camera in the device, likely to at least 13MP, over the 8MP shooter found in the original Nexus 5.
Of course, one of the most pertinent questions that users will have about the 2015 Nexus 5 is about who will make it. Latest rumors suggest that the device will be made by LG, like the 2013 version, and is codenamed the "LG Bullhead."
Another interesting rumor about the device is that it will include an iris scanner, taking things a step further than the fingerprint scanner also included on the device.
Last but not least is the release date of the device. Google, as always, has remained very tight-lipped about the upcoming Nexus 5. However, latest rumors suggest the company is targeting an October or November release.
Of course, the Nexus 5 isn't the only device expected from Google this year. Google is also expected to release a follow-up to the Nexus 6 that was released last year. This year's Nexus 6 is expected to be built by Huawei and be codenamed "Huawei Angler." It is expected that the Nexus 6 will also be released later this year. It is also expected to be slightly smaller than the 2014 version, coming in with a 5.7-inch display, 0.3-inches smaller than the 2014 Nexus 6.
Releasing both of these devices will put them head-to-head against Apple's iPhone 6s, also expected to be released this fall. Both of the devices will feature Google's latest mobile operating system, currently dubbed Android M.
