This phone is octa-core MediaTek MT6753 processor and it comes with 3GB of RAM. Good for day to day activity of smart phone like gaming, surfing and multitasking. I had not faced any problem from last 48 hours like heating or hanging while playing heavy 3d graphics games. It comes with good battery as compared to others. Regarding camera, its good to we can use it in day and night time too. I don't know why some users compare phone camera images with DSLR images. See starting of good DSLR comes in the range of Rs 40,000 with good lens. DSLR working mechanism is far different than phones. In DSLR many things work together(like condenser lens, focal plane shutter, reflex mirror etc) to get clear and good pix. So please don't compare the quality of DSLR pix with any phone camera pix. In K4 Note, yellow light is there to adjust white balancing while shooting outside. Speakers are good to play the music but not so loud like other Chinese local brands. Front speakers they are awesome. Heating problem is there in every android phone from Samsung to Sony. And this heating is only for few minutes ranging 5-10 minutes max as we shut down the heavy operations in phone. Anyway phone is good in the price range and far better than others. Don't worry about Note 5 Launch, as it will take 3-4 months to launch in India. And every time there will be new launch or announcement of phones. "Never allow waiting to become a habit. Live you dreams and take risks. Life is happening now."
