Hii guys, I am using lava for call with a smart phone since 2 years. I have not received any problem about it’s performance and system. When we are using a smart phone, we confused about it’s category mobile phone but I think lava is one of best. If you thinking about, don’t worry because it is faithful mobile phone. It’s price is less with good performance. It’s sound reception is osm, it is my likely property of lava. It’s bestest.
