There’s been no announcement about a successor to the Nexus 4, but speculation kicked into high gear over the weekend when an Android-focused blog published what appeared to be a leaked draft of the service manual for a Nexus 5.

According to the manual the smartphone would be made by LG and would bear a striking similarity to the Korean firm’s already-released smartphone model, the G2.

The blog, Android Police, writes that LG later asked the it to remove the manual from the Web site.

The document indicated that the Nexus 5 would have a 4.95-inch screen, slightly smaller than the LG G2’s 5.2-inch screen, with 1080p HD. The blog also reported that the phone would have an 8 MP camera in the back, rather than the 13 MP camera in the G2. The Nexus 5 is also expected to have a quad-core Snapdragon processor, and come in 16 GB or 32 GB versions. That would be an improvement over the Nexus 4, which came in 8 GB and 16 GB versions.

The alleged updated phone also looks to support LTE, unlike its predecessor.

Speculation about the Nexus 5 has been growing since Google cut the price of its Nexus 4 and completely sold out of the phone in September. The timing seemed about right: The Nexus 4 was announced in October 2012.

The firm also fanned the flames when it removed a video promoting its newest version of Android that showed an employee using as as-yet-unreleased smartphone that had Nexus and LG branding.

Many are predicting that the Nexus 5 will be the first Android phone to launch with Google’s latest version of its mobile operating system, nicknamed KitKat. Google hasn’t offered many details about the system other than its name, which came with a tie-in promotion from the classic candy bar maker.

The information that is available on KitKat indicates that it could have a serious visual makeover, with tweaks to make it easier to print from mobile devices, as CNET reported.
