In may I bought a galaxy j3 luna pro at walmart through straight talk. The carrier is verizon. A couple of weeks ago it started playing the universal studios theme song. It has since done it 5 times. I have one ringtone I wanna sedated on it. The phone was muted and I haven't watched any movies on it. I also had all social apps closed including YouTube. Can anyone tell me what's going on & if theirs have done something like this before. I do not have the theme downloaded to my phone.
