Its been 1.5 or slightly more years since I am using redmi 1s and I must say it was an awesome product back then and still today its performance is awesome.I wont be mentioning the detailed features but some key specs are 1gb ram, 8mp rear camera with flash and 1.6 mp front camera.Its a quadcore device with snappdrogon 410 and adreno 320 gpu and its clocked at 1.5 ghz and 300mhz respectively.
I bought this phone at a cp. of 6000 inr and earlier was using sony xperia tipo dual.Intially there were problems with miui ram management and heating but with latest update that is the MIUI 7, the phone is a gem but if u want to unleash the real power of this phone then use mokee rom based on lollipop. I am currently on mokee rom and phone performs just awesome.I can play asphalt 8 in high graphics with negligible lag which doesnt ruin your gaming experience at all.I can play almost all the high end games without lag.But if u want the best performance use greenify app and xlock your dwvice at 300mhz of min frequency and 1.19 ghz max frequency with ondemand and cfq.One thing which still amazes me about this phone is its camera which is by the best under 9000 inr even today.The sound output from the speakers is great and with my audio technica clr100 earphones the sound is just marvelous. Now one thing I want to mention is the build quality and the screen(With asahi dragontrail protection is even better than corning gorilla glass 3).i have dropped the device on screenside from a height of 4-5ft and not even a scratch is there on the screen till date and I dont even have a screen guard installed.U must be thinking whats the point of reviewing a product which is no longer available in the market but I just did it because I think this device is underrated. I have posted screen shots of my phone configuration and sample picture of redmi 1s rear camera.
