There is no more issue in performance but as it has 1.5 GHz Octacore processor and 2Gb ram the battery backup is very less. The company should have put it a minimum of 3000 or 3500 may of battery. The phone heats quite fast .When gaming format comes it works fabulous .The battery level drains very fast but It Charges full in about 2hours. It has an additional feature called 360° Camera which captures the photo in 360°.
