I bought lenovo k8 note 3GB and 32 GB varient 2 years ago. And here are my reviews about it after deep usage. The battery life is good. Lasts about full day on Medium usage , and about half a day on high usage ( watching movies , gaming etc) The processor is incredible as it gives outstanding performance on even heavy games like pubg , asphalt 9 etc. I have attached a recent screenshot of my geekbench score , which beats any device under 10000. the camera is fair , not excellent. Gives decent image quality in good lighting. However lacks image stability. Design is good. But could have been improved by a lot. So far , I only noticed few lags. Otherwise uninterrupted performance. Moreover a decent device for the price.
