Received the product before the committed delivery time. With lot of expectation, started using it. The following problems i have faced..

1. Touch did not worked properly. (struggled to type the wifi password)
2. Unable to accept it is running with 2 GB ram & Quad core processor
3. Heating problem. Unexpected heat generated while start using Google maps. Tested with other apps too. Faced similar problem.
4. Application responds very slowly when mobile heats up.
5. Tried Battery saver mode first time in new mobile. Display went blank and struggled almost 5 minutes to get the display back.
6. Over heating during charging.

The above are the problems i have faced in one day usage. Raised return request, but received mail from filpkart saying that return request rejected from vendor. Customer care says that technical team will evaluate the device and will update on the return decision. Have to wait.

Good things:

1. Light weight
2. Good audio and video clarity.
3. Primary camera is good
