Recently I have sent a lot of messages and they are almost fake.
But if not fake, I use SmsRetirever API with app signature in order to read the message content and verify the phone automatically without user interaction.
I saw that true caller has a feature something like flash call verification. The problem here is that google will not allow me to listen for the calls history unless my app core uses this feature.
I saw a lot of APIs that provides this feature but I don't want to use any third party due to privacy restriction.
Any idea how to implement it on android devices? listen to call logs and i need to listen for only one phoneNumber
