Morse Code?
iPhone SE Night before last update 11.2.6 was installed during the night. When I turned on my phone the first thing that happened was a Morse Code message came up. Either MKMM, or KMKK. I think it was he former. It went on for a while. Went to messages to see if there was a phone number. Nothing appeared. Went to recent calls, nothing appeared.
Now when I open my phone, it already has one of my apps opened. I can close the app and everything seems to work fine.
Typically in a day I might get a few phone calls, under five minutes and at the end of the day, I'll have used 5% of my battery. Yesterday, a few phone calls of less than 3 minutes. At the end of the day, I had used 60% of my battery!
Phone hacked? Reset the phone? Any ideas what's going on?
