Definitely going to need a new phone, OP. The reason that is there is because your iPhone has stage 4 cancer and is slowly dying. I would recommend yeeting the device as far as you can into your neighbors yard because the radiation coming off of it due to its disease is harmful to your body. If you somehow suck at throwing things and can’t throw it into your neighbors yard, put it in tinfoil and carry it to your nearest radioactive material disposal facility and let them take care of it. Stay safe out there!
