I suspect the "Phoner" app from the Apple App Store compromised my iPad along with the device's IMEI.
After accepting a phone call on the iPad (I later found out to be a Google-generated listing), I noticed that the call record function that usually required me to push a button to start has turned itself on automatically. Now every time I place or receive a phone call the record button comes on by itself automatically.
Since this issue started, all email I've sent to certain addresses from my iPad have not been received and I am not receiving email from certain address.
I contacted the Phoner tech support, they state they have never seen a case like this before.
What steps can I take to find out if the Phoner app and/or my IPad have been compromised?
