Android Messages, the competitor to iMessage. The parent claimed that Google resists encrypting anything so they can mine your data. I was merely trying to ask for accuracy. I don't know the technical aspects of every Google messaging app but as the other responses in the thread confirm, Messages is end to end encrypted by default for non-SMS messages.
I just checked and Google does have a Messages app, different from the Messages app on my phone, probably by Samsung, which deals with SMSes. According to Play it has 1B+ downloads so it's probably preinstalled.
Anyway, the competitor of iMessage and Messages is WhatsApp. Nobody is sending me SMSes except banks so even iPhone users use WhatsApp to send messages to friends and to groups in my country. If somebody would insist using only iMessage they would be out of the loop. And about Messages, well, I don't have that app, I receive no SMSes, I still communicate with everybody so I guess that nobody uses Messages too.
