The smartphone industry's most recent rumor comes via leaked snapshots of the rumored giant from the HTC camp, the HTC Holiday.

The photos were posted by a member of XDA Developer forum, who spotted the device being sold on Craigslist. He then purchased the device and posted the pictures online.

The Holiday is rumored to boast a 4.5-inch display, supposedly the first of a new wave across the Android landscape with 4.5-inch displays.

The recent breed of Android phones, like Samsung Galaxy S2, HTC Thunderbolt and Motorola Photon, found expression in 4.3-inch displays. The trend seems to highlight that the next barrage of Android phones will follow the 4.5-inch form factor.

Samsung first released a 4.5-inch Android phone called the Infuse at CES 2011. However, the most recent report confirms sighting of a 4.5-inch 4G LTE Samsung Galaxy lookalike phone doing rounds in Korea. The phone is called Samsung Celox.

It is rumored that HTC Holiday will feature a 4.5-inch capacitive screen with 960x540 screen resolution. It is expected to be powered by a 1.2GHz dual-core Qualcomm MSM8660 processor. It will offer 1GB RAM and will sport an 8MP camera. Holiday is surmised to run on Android Gingerbread juice. The phone is slated to be released on AT&T network. The phone optimizes Android's latest version of OS for smartphones, the Gingerbread.

Samsung Celox can counter the HTC Holiday threat as it features superlative specifications. Celox also features a 4.5-inch Super AMOLED screen with 800x480 screen resolution. It is expected to be powered by a 1.5GHz dual-core Qualcomm Snapdragon APQ8060 chipset.

Celox will also support an 8MP rear-facing and 2MP front-facing cameras. It is also reported that Celox will sport a 1750 Li-ion battery. The Celox is a tad thicker and heavier, weighing 4.5 ounces and is 0.36 inches thick. The Celox runs on Android Gingerbread juice.

The fight in the Android smartphone landscape seems to be all about faster processor and bigger screens. And the aforementioned devices with their marvelous spread of specifications underscore the fact that Android phones are getting bigger, better and faster.
