With the Samsung Galaxy Tab 10.1 WiFi and the HTC EVO 3D arriving on Sprint this month, you would think the mobile carrier would pause for a while to take a breather. Nothing could be farther from the truth. Sprint has more in store for the third quarter of 2011. This Is My Next received an insider tip from Sprint saying that the third quarter of 2011 will also herald new Android devices on the mobile network–two Android handsets, in fact.

The first one is a QWERTY smartphone. Last year, Sprint launched the Samsung Epic 4G, and its successor is coming out some time this third quarter. The Samsung Epic 2 bears several improvements to its predecessor, except that we feel the improvements are not that epic at all. For instance, it will still sport a single-core Hummingbird processor, but with a slightly higher clock speed than its earlier sibling. The earlier Epic 4G ran at 1 gigahertz, while the new one will run at 1.2 gigahertz. The Samsung Epic 2’s screen will remain 4-inch with Super AMOLED Plus, but its rear camera acquired 3 more megapixels (i.e., the Epic 2 will have an 8-megapixel camera).

Very little info was leaked about the second handset. It was only referred to as a “full-touch 4G” phone from Samsung. This mysterious handset could possibly be the Samsung Galaxy S II, which is rumored to be launched on Sprint as the Samsung Galaxy Within. It’s also rumored to have WiMAX capability but no physical keyboard.

For now, the Samsung Galaxy Tab 10.1 WiFi and the HTC EVO 3D are the new Androids on Sprint, but are you willing to wait a bit for the coming of the Samsung Epic 2 this third quarter? A QWERTY keyboard and Super AMOLED Plus display can make your smartphone quite a treat, you know.
