As the name suggests Xperia play is designed to be a gaming device, it is a 175g slider that slides open to give a gaming keyboard instead of keypad. With such design you can’t expect the phone to be thin; Xperia Play is 16mm thick. Galaxy S2 on the other side has a completely different design, it is the slimmest phone around that is only 8.5mm thick and weighs only 116g. It is difficult to say which phone has a better design considering that they are designed for different purposes but both have excellent design that suits their functionalities.
Samsung Galaxy S2 features the Super AMOLED capacitive touch screen with 16M color and 480 x 800 pixels resolution support. The nice, crispy and bright touchscreen is 4.3 inches. Xperia Play comes with a slightly less appreciated LED-backlit LCD, 4.0 inch capacitive touchscreen with 16M color support and 480 x 854 pixels resolution.
High Multimedia capability is the main focus of both these smart phones, and that can not be ensured without a powerful camera. Galaxy S2 is again ahead of the race with a brilliant 8MP camera that is able to record HD 1080p video at 30fps, it also has image stabilization, geo-tagging, face and smile detection and touch focus features. The 5 MP camera of Xperia play is able to record WVGA video. It supports image stabilization and geo tagging features.
Processor and OS:
Galaxy comes with a 1.2GHz dual core processor which speaks for the power the 8.5mm device has. Xperia play features a 1Ghz processor which is not a bad choice for the phone of its category. As far as the OS is concerned both of them have the latest Android 2.3(Gingerbread) OS.
Xperia play has 400MB of internal storing capacity and 512MB of RAM whereas Galaxy S2 comes with 16 and 32GB versions of internal memory with 1GB of RAM. The external storage in both devices can be extended up 32GB via micro sd card.
Galaxy S2 is really a gem from Samsung being such a powerful device with impressive features but all that power packed in an extremely thin device, Xperia play on the other hand is also something like never seen before, the gaming focused design of the smart phone is enough to catch the attention of gamers.
