I have always trusted Nokia for its durability and battery back up. With this believe I purchased this phone from my local mobile store. This phone works very slowly. it takes too much time to open any application. It does not provide any software update. Even after using 6 months I did not find any update.The battery drains very very fast 3-4 hours in standby mode. Only sound and camera is good. I think nowadays one would never buy an android phone for its sound and camera only. very bad experience
