The top five Galaxy S2 contenders are: Google Nexus Prime, Motorola Droid Bionic, Motorola Photon 4G, HTC Holiday, and HTC Vigor.
Galaxy S 2 was announced at the Mobile World Congress in Barcelona in February and since then the phone has continued its march. Galaxy S2 comes to the U.S. after selling a record 5 million units in 85 days in Europe and Asia and is the best-selling Samsung phone ever.
Galaxy S2, which runs on Android 2.3 Gingerbread OS and sports Samsung's TouchWiz UI, comes with an 8-megapixel camera with flash and can record HD video in 1080p offering the richest video content on a smartphone. The phone also has the front-facing 2-megapixel camera for video chat.It is powered by a dual-core 1.2 GHz ARM Cortex-A9 Mali-400MP GPU Orion chipset. The phone comes in 16/32GB internal memory configuration with 1GB RAM.
It is rumored to sport 4.3-inch or 4.5-inch qHD display with 960x540 pixels screen resolution. It is surmised that it will be powered by a Texas Instruments OMAP4430 1.2 GHz processor optimizing 1GB RAM. Droid Bionic is expected to feature Li-ion 1930 mAh battery and will feature an 8MP camera.
But, does Samsung Galaxy S2 has enough firepower to challenge the top 5 new 'super' smartphones that run on Google's Android?
Google Nexus Prime:
The Nexus Prime will most likely be the first smartphone to run on Android 4.0 "Ice Cream Sandwich" and will likely be launched in October.Ice Cream Sandwich will combine the best features of Honeycomb (Android tablet OS) and Gingerbread (Android smartphone OS).
The Google Nexus Prime has been called an "absolute beast" among smartphones and there is a very good reason. The smartphone will boast a dual-core Snapdragon processor that will include Krait chips from Qualcomm, and a 1GB RAM.
It is not yet known if the processor will be of either 1.2GHz or 1.5GHz. The Krait-based Snapdragon processor will have the ability to run at a lightning speed of 2.5 GHz per core at the least, which will make it more than 100 times faster than a normal ARM-based CPU.
Nexus phone will feature a 720p HD “monster-sized" display, a 4G LTE radio, 1GB of RAM, 1080p HD video capture and playback, a 1-megapixel front-facing camera, and a 5-megapixel rear camera.
Nexus Prime is reportedly being built by Samsung and that it may sport a 1.5GHz dual-core processor as against the single core, 1GHz processor in the Nexus S. The display will be upgraded to a 4.5-inch 720p Super AMOLED HD screen, whereas the Nexus S display is 4-inch and with lower resolution.
Motorola Droid Bionic:
The Motorola Droid Bionic is powered by Android 2.3 and it looks similar to Droid X2, which is another dual core smartphone without 4G support. Droid Bionic has a huge battery power, and 4G LTE.
The Droid Bionic's expected specifications include Wi-Fi 802.11 b/g/n, DLNA, Wi-Fi hotspot (connects up to 8 devices and when on 3G connects up to 5 devices), Bluetooth version 2.1 with A2DP and EDR technology, microUSB version 2.0, touch-sensitive controls, multi-touch input method, accelerometer sensor for UI auto-rotate and proximity sensor for auto-turn-off.
Motorola Photon 4G:
Motorola Photon 4G has 4.3-inch qHD capacitive touchscreen (960x540 pixel resolution), multi-touch input method, accelerometer sensor for UI auto-rotate, proximity sensor for auto turn-off, touch-sensitive controls, 16GB storage (up to 32GB with microSD support), 1GB RAM, 2GB ROM, WiFi, Bluetooth, 8-megapixel camera (with dual-LED flash, autofocus and geo-tagging features), secondary VGA camera for video chat, Android 2.3 OS (Gingerbread), 1 GHz NVIDIA Tegra 2 AP20H dual-core processor and HDMI port.
HTC Holiday:
The Holiday is rumored to boast a 4.5-inch display, supposedly the first of a new wave across the Android landscape with 4.5-inch displays.
The recent breed of Android phones found expression in 4.3-inch displays. The trend seems to highlight that the next barrage of Android phones will follow the 4.5-inch form factor. The arrival of such a piece from HTC is cause for concern for Samsung.
HTC Holiday is expected to have 1.2 GHz dual-core Qualcomm Snapdragon processor with 1GB RAM, Android 2.3 Gingerbread OS, 4.5-inch qHD display with 960x540 screen resolution, 8MP dual-LED flash rear-facing camera with 1080p video playback, 1.3MP camera for video chat, HSDPA up to 21 Mbps, HSUPA up to 5.76 Mbps, Wi-Fi 802.11 b/g/n DLNA support, advanced Bluetooth version 4.0 with A2DP and EDR, and microUSB version 2.0.
HTC Vigor:
The phone from the HTC camp which is due to hit Verizon's 4G LTE network is rumored to sport a 1.5GHz dual-core processor. The phone, which is touted to be a replacement for the HTC Thunderbolt, is expected to don a 4.3-inch display with 1280x720 screen resolution.
Vigor is surmised to be fitted with an 8 MP camera. It will run on Android Gingerbread juice. Also it is expected to offer 1GB RAM, 16GB internal storage and is also surmised to incorporate Beats Electronics Technology - best known for the high-performance line of headphones.
