Someone else responded to a text message
There is another person responding to text messages. Very simple responses such as “talk later” or “ok”. This occurs randomly and it happens with iPhone users as well as android text messages. The Apple ID has been changed and I’ve reset the phone back to factory settings and reloaded the saved backup. I’ve also checked setting for Text Fowarding and there’s no forwarded message detail there. Is the phone compromised or is it the phone number? Will getting a new phone number or device correct this? It’s a iPhone 7.
iPhone 7, iOS 11
