I use facebook messenger from the day it has been released . it is so good to use that I have stopped using facebook and started using only the messenger to chat. Facrbook consumes the most data and charge but messenger doesnt . the best thing is we can evern deactivate facebook and enjoy using messenger alone . the stickers are so attractive compared to other mesaaging social apps. The video quality is really good and we have lot of changes in every update. I love this app.
