Samsung, HTC and Motorola are pushing software limits and trying to conquer the smartphone world by boosting their devices with enviable speeds.

Traditional devices like PCs, laptops and notebooks are slowly but steadily losing ground as many consumers are opting for portable devices.

High resolution touch screen display, interactive web browsers and powerful cameras are making smartphones a replacement for not just PCs but also cameras.

As AT&T, Verizon, Sprint and T-Mobile are building their network in the U.S. with 4G network, LTE is becoming the norm and consumers are expecting their devices to provide them with the speed to catch up with their fast lifestyle. Hence Samsung, Motorola and HTC are bringing out their best feature phones to provide the data hungry consumers with LTE support for high quality browsing and video streaming.

Motorola Droid Bionic has gone a long way as to become the first dual core smartphone to feature the LTE technology. Unlike HTC Thunderbolt, Droid Bionic has impressed the users with long battery life. The 4G-enabled Verizon smartphone could last 8 hours while Droid Bionic gave 10 hours and 21 minutes talk time with 1735 mAh battery.

Meanwhile, HTC’s Holiday is expected to be AT&T’s first LTE phone. HTC Holiday looks different from other HTC phones as HTC is making a change to the rear of the phone. BGR reportedly sighted the phone running on the AT&T's upcoming LTE network with an impressive 29.71Mbps downstream and 6.43Mbps up speed. This speed is greater than anything Verizon network could offer, but the high speed is likely due to the lack of users on the network at the moment.

And finally we have Samsung Galaxy S2 LTE phone which is the most powerful Samsung Galaxy phone yet, overpowering the versions going to AT&T (commonly known as Attain), Sprint (Epic Touch 4G) and T-Mobile (widely touted in tech world as Hercules).

However, Verizon Wireless is the only carrier in the U.S. that will not offer the Samsung Galaxy S2. But with Samsung Galaxy S2 LTE version not yet announced for any carriers, the missing link in the puzzle must be here. The Long Term Evolution-equipped version may join the likes of Verizon network. The Galaxy S2 LTE version is not just fast but bigger too, and features faster UI, powerful superfast processor and a huge display. It also features 3D graphic performance for better gaming and other applications execution.
