Hi guys, now I am talking about redmi 3S prime. It has a better backup of 4100 MA. It stays 2 days.it has a prise of ? 8999. is very good phone in case of of price it gives more more. it speaker is also good but it gives sound more in 9% and 10% . it has very good operating system which is MIUI 7 and it has also getting an update of 8. its camera is also nice it is 13 megapixel. which is quite quite good and selfie camera is 5 megapixel. which is enough to take a selfie. during selfie it creates smoothen image. it has 2 GB RAM RAM GB RAM RAM and 16GB internal, but it is 10 GB usable it takes too much space in the system. its PPI is also nice that is 294, it has very good viewing angle. main features is it has IR blaster which is very useful it controls all apparatus but some are not work. USB OTG can work on it on it. It is made up of metal body but at the edges it has some plastic used but in the sector it is nice. Give some inbuilt app when we buy mobile which is very useful just like WPS office. It has sound button and power button are plastics they look like metal but not metal. Is display is also scratch resistance but it is not a Gorilla Glass the companies only mention it is a scratch resistance . it has very good notification light. Which has various colour. sometime during most using phone it’s directly restart. thanks.
