The Samsung Galaxy S2 is still one of the best Android phones on the market despite being more than one year old. The phone's excellent hardware has prevented it from being outdated any time soon. Unfortunately, as Google continues to roll out new iterations of Android, phones such as the Galaxy S2 risk becoming outdated.
In terms of hardware, the Galaxy S2 packs a mean punch, especially when you consider how much cheaper the phone is than any other on the market. The Galaxy S2 was one of the first Samsung Galaxy-brand products to see exorbitant popularity in the U.S., and it set the table for the success of the Galaxy S3. The Galaxy S2 runs on a dual-core 1.2GHz processor that's still pretty fast when compared to most Android phones. The only downside is that that the phone comes preloaded with Android 2.3 Gingerbread, a vastly outdated version of Android.
But now there's hope for Samsung Galaxy S2 users. Thanks to the incredible development coming from dedicated Android programmers, Android 4.1 Jelly Bean has been made available to Samsung Galaxy S2 users. After the upgrade, the Galaxy S2 can be expected to compete with some of the top-of-the-line smartphones on the market.
