I have a issue when I click the videos, there's so many interrupt like it stop when someone sees new messages, I can only hear the audio and the video is all black or when I try to exit the video but it won't. When I try to leave the video chat, it won't exit and I force myself to restart the phone. I have to add that a recent problem is that I can't send pictures and audios while my friends can still send theirs. What's happening? It's almost my time of class session and you need to fix it.
