One of the biggest rivals of the iPhone 4S seems to be the Samsung Galaxy Nexus; it will be interesting to have a comparison of the features of the two competitors.

Samsung Galaxy Nexus has a 4.65-inch Super Amoled HD screen with a resolution of 1280 x 720 and a dual-core 1.2GHz processor together with 1GB of RAM. There are two storage options - 16GB and 32GB. The iPhone 4S has a smaller screen with a Retina display of 960 x 640 pixel resolution at 326 ppi. The iPhone 4S is powered by a dual-core A5 chip, which also has dual-core graphics capabilities.

Samsung Galaxy Nexus weighs 135 grams, is 8.9 mm thick and has a 1,750 mAh battery to power the device. It features a front-facing 1.3-megapixel camera and a rear-facing 5-megapixel camera with LED flash, zero shutter lag and has full HD recording capabilities. The iPhone 4S measures 9.3mm and is heavier, too, at 140g. The iPhone 4S has an 8-megapixel camera, capable of capturing 1080p video footage. It has 3,264 x 2,448 pixel pictures. It will capture vibrant photos, especially in low light. The camera is claimed to be 30 percent sharper than the one found on the iPhone 4.

According to launch details, Samsung Galaxy Nexus will incorporate Near Field Communications (NFC) technology and HSPA+ and LTE connectivity. The device will have Bluetooth 3.0. However, the primary selling point of Samsung Galaxy Nexus has to be the Ice Cream Sandwich Operating System, which is a major revamp of existing Android platforms. Google has created a brand new font that has reportedly been optimized for HD displays and eliminated all hardware buttons in favor of virtualized buttons, much like the Honeycomb platform. A combination of the Gingerbread and Honeycomb platforms, the Ice cream Sandwich adds a new-look, extra features and even more levels of efficient customization to keep the user engrossed.

Meanwhile, the iPhone 4S, equipped with the newly announced iOs 5, is touted as being very simple to use. It is a free software update bringing over 200 new features to the iPhone including a location-aware reminders app, Newsstand, wireless syncing, Twitter integration, iMessage, a notification bar and widgets.
