Reliance Retail 's Lyf brand of smartphones this week launched two new handsets in its Water series - the Water 4 and the Water 6, priced at Rs. 7,599 and Rs. 8,999 respectively. Both the Lyf Water 4 and Lyf Water 6 smartphones have nearly identical specifications, with minor differences such as inbuilt storage capacity, colour variants, weight, and dimensions. Both smartphones run Android 5.1.1 Lollipop and are dual-SIM (Micro-SIM + Micro-SIM) capable. While both SIM slots support 4G, only one can be used for 4G connectivity at a time, while the other will become 2G-enabled.
