So, I had got a Motorola XT615 a year ago and I have always experienced problems with it, but today, I've found the most annoying and weirdest one. I was on the bus and my friend grabbed my phone out of my hands and I grabbed it back. Then, a minute later it started vibrating, non stop. I found pushing down on the top left corner would stop it but if I released it, it would start again. I tryed taking the battery out and letting it sit out for awhile but it still does it. It even vibrates while its off! I have to take the battery out to stop it. Can anyone help?
