NOTE 3

Hi,<br> <br> I don't know who to speak to, but my phone has been unlocking on its own and going into my e-mails, whats-app and internet and typing stuff on its own. it took a video as well in its own. I did take it to the store and they said they can't see anything wrong with it. This is the second time its happening, my phone got very hot at the back and my battery is now swollen up because of it. My sister did take a video of my phone doing stuff on its own if you want to see it for yourself. I never had problems with my phone, please can you help me i bought the phone a year ago.
