I had used redmi note 4. It consists of 4 GB Ram so it performs task faster. The sound reception is good.Its less weight and user friendly, dual sim. The battery is very good, for me it stays for almost 2 days if I use internet also.It has features like fingerprint, active noise cancellation. The camera is also good, front its 5MP and back 13MP. Phone looks stylish.Its worth buying redmi note 4. It’s not expensive.The money you spend will come back.Its worth.
