I bought lyf wind 1 last month on 28 july 2016 of rs6300, smartphone is good but lyf should provide 2gb ram module in this price range, processing power is good but bcoz of only 400mb usable ram phone struggles in multitasking more than three tab.
In my 13 days of 4G experience I have completed nearly 90gb of data, speed is good not excellent but better then 3G.I get speed varing from time depend of network load.
1am to 8am 28mbps, 8am to 3pm 18mbps and 5pm to 12am 2.5mbps.Maximum speed in my area received is 48mbps.
Finally at last good experience of 4G on jio.
