HTC has a bona fide hit on its hands with the EVO 4G, which Sprint apparently can't keep in stock anywhere. On top of that Samsung is already teasing about the U.S. launch of its Galaxy S Android handset. Android smackdown on the way?Sprint was sure to let everyone know that the EVO 4G broke all its previous one-day sales records. The device has been a hot seller. In fact, the device is so hot, it's out of stock pretty much everywhere. A recent check of two local Sprint stores as well as Sprint.com shows that it isn't available.

Sprint won't even let you order the EVO 4G from its online store right now. The message reads, "Sorry, this device is so hot we can't keep it on our virtual shelves. Check back later -- more are on their way!"

It is a well-deserved success for HTC.

As for Samsung, it has launched a teaser web site for its upcoming Galaxy S handset.

Samsung's latest Android phone leaps towards the top of the heap. It runs Android 2.1 and boasts a four-inch WVGA Super AMOLED 800x480 pixels. Hardware features include support for U.S. 3G bands, a 5 megapixel camera with user-facing VGA camera for video sharing. It can record HD video in 720 pixels at 30 frames per second. It has GPS, Bluetooth 2.1+EDR and Wi-Fi. It will support microSD cards up to 32GB and will be boxed with a 16GB card.

Samsung says, living a "Smart Life" requires intelligence, and the Galaxy S delivers just that by utilizing personal preferences to gather information online that each user needs and wants. With a user-defined daily briefing (instant access to weather, news, stocks, and the scheduler), lightning-fast processing speeds and location-based search options like Layar Reality Browser.

The Galaxy S integrates with a variety of other devices, such as notebooks, TVs and cameras, the highly advanced Social Hub plugs users quickly and conveniently into their complete world of social networking and email.

Expect to see it available from a U.S. carrier soon.
