The first thing I have to say about facebook messenger application is that this is the wrost messenger app I have ever used.
It took so much space on ram and made the phone speed slower than before.Although it provides you so much stickers, gif files but when I go for voice call or video call through messenger it lags all the time. Some time it shown you online even after you loged out from the application. It took more data speed to work properly.
So I personally think that facebook messenger is not an ideal messenger application.
Thank you.
