Right now I am using redmi 1s, as per me and my usage it is the best cell phone in the budget of Rs.6000. I have been using this cell from last 6 months. it gives you 1 gb Ram which helps in multitasking and didnot show you hanging problem. I am playing games in this cell like candy crush, clash of clans, farm heroes which are more than 50 mb in size stil there is no hanging issue.
It gives you good camera for selfies at front and back camera is also good to take normal pics with good picture quality. It also supports OTG through which you can use pen drives on your phone anywhere anytime. I am fully satisfied with this cell and promote others to use and buy it.
