My sister using this from 1 month.For 8 days it was working good.After that it is heating like a iron even I am using a back cover.It has a 3 gb ram still it is lagging during multitasking.Sometimes back button is not working.If you are surfing internet using 3g or wifi for 20 minutes it will heats upto 44 or more than that, that time the touch of upper screen is not responding.
So dont waste your money.In one month the mobile condition is this.Dont know what will happen after 1 month.
