My son bought Lava Iris X8 for me from his first salary 3 days back. The smart phone looks luxurious and offers all the features which you can expect from an android phone specially the 1.4 ghz octa core processor. It is fast and does not hang at all. I can manage my E-mail, my contacts and social apps, music etc very easily. The camera is also very good and so is the battery backup. It is a nice phone and you can get it under 10K.

InFocus M330 is the best octa-core processor smartphone under 11K.
