Hi, I have a relatively new mobile phone, Honor P7 lite, and almost from the beginning I have a problem playing songs and videos. The problem seems to be that I'm playing a song or video that cuts itself off after a few seconds. Sometimes it's two seconds, sometimes it doesn't take ten minutes. I thought if it wasn't a movement or a gesture, but when I put my cell phone on the table and don't do anything on it anyway, it happens again. I don't know what it could be. Please help...
