Redmi 1s is the first venture of Xiaomi in India. As hoped , it became one of the most popular and sold phone in India.
Redmi 1s comes with 4.7 inch IPS LCD display. It has a pixel density of 312 ppi , which makes colours pop. The 8MP & 1.6 MP shooters are decent enough to produce good quality images. The CPU is a quad core 1.6GHz Snapdragon 400 and GPU is adreno 306. It is good in gaming & the battery life is also good. The only problem is heating issue and that is also not a problem after updation.
Overall it is a good phone which gives a great value for money. It also provides great customization abilities using MIUI launcher.
