I am using LAVA IRIS 455 is not a good phone as it comes in half gb of ram so it is too slow to use and also so much problem in using as it works very slowly. Camera is too bad as pixels of photograhs clicked with its camers is too much bad and its images are too much black. It is also not thick to get easily in my pocket. Battery backup is worst as it comes zero in only five-six hours. This phone not works till its warranty period. So, do not buy this mobile as you come in problem when you buy it.
