Last year I bought this phone when jio was providing ulimited offer for only lyf users.
The internet and network quality by jio was excellent but Lyf Water 11 got too much of issues.It got a very low battery bakup, battery only last for 2 to 2.5 hours and the user needs to charge the phone manier times but the phone gets excess heated while charging and also during calls.the sound quality was good but only at home outside home even the ringtone was not clearly audiable.It have got a 3 gb of ram and 16 gb of ram which is not suficcient for phones with hibread slot.it have got a good camera quality but it can be much better.
If You are looking for a phone in this range then you may go for motorola or redmi as they provides much better feature in the same price
