As September draws near, fans and non-fans alike await for the official release of Motorola Droid Bionic, arguably one of the most powerful Android smartphones yet. The Droid Bionic has not even debuted, but it was so powerful that it was reviewed side-by-side with the Samsung Galaxy S II, dubbed as the best smartphone during its time.

You think the Moto vs Samsung rivalry is over? Samsung is responding with the second generation S II, unofficially named “Stratosphere,” and the competition is set to heat up even further.

Verizon Wireless is reported to be releasing another powerful Android smartphones alongside the Droid Bionic in September, as suggested by a leaked document from IGN. Yes, it is the Samsung Stratosphere, revealed as the second generation S II, with its 4G capabilities and Android 2.3 Gingerbread operating system. The document further states that on October 5, Verizon will release the HTC Vigor, the replacement to HTC Thunderbolt.

What is more intriguing is that both the Droid Bionic and S II seem to have similar features. The Droid Bionic boasts of Long Term Evolution (LTE) technology as an advanced feature in connectivity, but reports say that S II will include the feature too. In fact, the leaked document described the Stratosphere as 4G LTE capable.

Both the Droid Bionic and S II also have custom user interfaces. Motorola has dropped the MotoBlur name, but its UI is still present, while Samsung recently released its TouchWiz 4.0 Android skin and will reportedly implement it in the S II.

As manufacturers work to outdo one another, the consumer always emerges as the winner. Stay tuned for more updates as we count the days to September.
