Whatsapp is most useable app for new generation.
The concept of whatsapp is sending msg to one person to another person without any distrub.layout and design was soo cool on whatsapp. It my daily use of whatsapp for many purpose.but one think I dont like in whatsapp its video call sometime I do videocall but this ahow of low quality of video while I using 4g handset and 4g network. While videocall they are too much distrubance. Whatsapp should add sciters like hike and facebook. It have soo cool.
