I bought this product around December 15 on which the software part was already updated. So I didnt had to go through the 300mb or some other updates people talk about. At 10k this is the best phone you can get if looks dont matter to you but performance does and you are tight on budget. Camera is descent in low light. The best part is the battery backup.
It can last like 6-7 hours of continuous usage of wifi music and all. But if you are a gamer, better buy something else. This supports 1080p display resolution due to which many higher end games like gta avengers dont run. On an average 700-800mb ram is only available to user, which I think should have been more. You can open multiple apps at a time and phone sound quality is also amazing. So overall its a good phone for general purpose daily usage.
