The first time happened when I walked onto the bus. I didn't have my headphones in and my phone dtsrted making a smoke alarm-type sound. The second time also happened on the but when I was listening to music without headphones and everybody told me to turn it off and it went away when I paused my music. Keep in mind there were 2 different songs. The last one that happened was just now when I had headphones in. I fear my phOne may be tapped. Please help.
