The two smartphones making waves apart from iPhone 5 are Samsung Galaxy S2 and Motorola Droid Bionic.

The Android-powered smartphones from Samsung and Motorola are on a spree to make their mark in days to come. Both the smartphones boast of super specifications and feature dual-core processors that offer blazing fast performance.

Recently, a poll conducted from April 1 to June 21 based on user opinions across Twitter, Facebook and other social networking services by Mashwork showed that 10090 opinions were about Samsung Galaxy S2 and 4738 opinions were about Droid Bionic as the social media listening company listened to 14838 opinions.

The release dates of both these smartphones are making customers wait on their heels. Motorola Droid Bionic is back in headlines after Motorola confirmed via Twitter that its much anticipated Verizon LTE phone will arrive this summer. It is pitted to be the most powerful 4G LTE Android smartphone based on its specs sheet compared to Verizon’s other smartphones like HTC Thunderbolt, Samsung Droid Charge and LG Revolution.

So far, the rumors are leaning toward an early July date release, expected to be on Independence Day. The latest leaks of the phone show it featuring laptop dock, which will surely entice more consumers to consider the Droid Bionic when deciding on their smartphone purchase.

On the other hand, Motorola recently said that it would unlock bootloaders in Q3 or Q4.

Motorola Atrix is rumored to be getting an unlocked bootloader with its Gingerbread update, most likely in July. Usually Motorola locks the bootloaders on its smartphones which prevents owners from fully customizing the device. Moreover, Verizon’s new tiered data plans will likely go into effect on July 7.

According to sources, Motorola wants to get rid of LTE phone’s battery-drain problem and change the processor along with the inclusion of latest version of Android. Also, Droid Bionic is expected to include the latest version of Motorola’s custom user interface mostly to accommodate the unlocked bootloader option. To prove the fact, a recently blurry cam image capture showed a Motorola Android smartphone with new UI that looks similar to Motorola's Photon 4G UI of Sprint -- which includes the latest version of Motorola’s custom skin on top of Android.

Meanwhile, Samsung Galaxy S2's release date is surmised to be July 24 in the U.S. The Verizon network recently confirmed the release to be in July, but the date remains unconfirmed. The Samsung Galaxy S2, known as “Function” at Verizon, may come earlier as Industry insiders indicated that Sprint is expected to feature a Samsung 4G device beginning in the third quarter of 2011, although that has yet to be confirmed. Most probably September may see the dawn of the Galaxy S2 in Sprint. AT&T will get an “Attain” and Sprint Nextel will market a “Within.

The release date of Samsung Galaxy S2 may be near. With Galaxy S2 outselling the iPhone 4 in the UK market, carriers across the U.S. may want to roll out their flagship device as they are increasingly aware of the sales they are losing due to smartphone’s ongoing delay. HTC has taken advantage of delays from both Motorola and Samsung as their two phones, HTC EVO 3D 4G and HTC Sensation 4G, respectively, are receiving rave reviews in the market.

Few features that bring Samsung Galaxy S2 the accolades are its Super AMOLED Plus display, unsurpassable performance, thinness, dual-core chipset and inclusion of NFC technology. Also, the TouchWiz 4 will allow consumers have a new customizable user experience that taps into the Social Hub, Game Hub, Readers Hub and Music Hub in order to provide users information in real time across five home screens.
