Samsung has done a great job at keeping most of the information about its next flagship smartphone -- the Samsung Galaxy S3 -- under wraps. There are hardly any details available about the smartphone at this time. In fact, Samsung has not confirmed that it will name its next highly anticipated top-of-the-line smartphone the Samsung Galaxy S3.

If the rumors are true, the Samsung Galaxy S3 will pack a 4.65-inch display with 720p high-definition resolution. The Galaxy series from Samsung has been known for its stunning visual displays, so most expect the latest device to be no different.

The Samsung Galaxy S3 hardware is rumored to be a quad-core ARM A9-based Exynos 4212 chipset that clocks at 1.8GHz. If this particular rumor is true, that would make it literally twice as responsive and fast as the iPhone 4S. Samsung also promises significant speed boosts and battery-friendly features.

Cnet UK predicts that the Samsung Galaxy S3 phone will come with 2GB of RAM and 32GB of storage -- plenty of power for most users. It's also rumored that the hone will have a 12-megapixel rear camera, which would be a step up from the 8-megapixel camera tha the Galaxy S2 has. The Samsung Galaxy S3 is expected to be running the latest version of Android (4.0 Ice Cream Sandwich).

Although it hasn't been confirmed, many are suggesting that the Samsung Galaxy S3 will be released on May 22 at a media event in London.

HTC One X

While most mobile device fanatics are focusing on the ongoing battle between Apple and Samsung, others are looking to HTC for the next state-of-the-art smartphone. One of its latest models, the HTC One X launched at Mobile World Congress.

The smartphone packs a 4.7-inch screen with 720p high-definition resolution, much like the Samsung Galaxy S3's rumored screen. HTC has been known for making sleek casing and this phone appears to be no different.

The HTC One X runs on a 1.5GHz quad-core processor and 1GB of RAM, which is slightly less than the hardware that the Samsung Galaxy S3 is rumored to be running on. The HTC One X also has 1GB of RAM.

The HTC One X has an 8 megapixel camera with auto-focus that's able to record full 1080p HD video. The 1.3 megapixel front-facing camera allows users to participate in video chatting at 720p high-definition. It runs on the latest version of Android (4.0 Ice Cream Sandwich).
