Lenovo A 6000 plus.best mobile phone I have used so far. It has 2 Gb ram and 16 g memory. I have been using it since 2015. Phone have very good battery backup. battery lasts for 18 hrs of regular use. Dolby sound quality is good. If you use good pair of headphones it will give you feel of theater.
Coming to screen quality, its not good but at this range it is good. Android upgraded to 5.1 which is working very smoothly. This 5inch screen mobile is worth for its money. I am using JIO sim on this. It gives some lag on 4g, as it is not, made for 4g but stil u can do some arrangement and use jio sim on it.
Overall it is worth for your money
