Re: In the settings for Samsung messaging app, what does "select default messaging type" mean and do
It's RCS. Sprint has it running on their network. If u and the other person have Sprint, select Chat and it'll communicate thru RCS (Chat). If u and the other person r on different networks, it'll communicate thru sms/mms.
I'd leave it on automatic. One time I was texting a friend thru Chat (we both have Sprint), and I hadn't heard from them in a while. I checked the messaging app and it said failed to send due to no data connection. I pressed resend and it went thru. Later I went thru the settings and selected an option that read if Chat doesn't send, use sms/mms automatically. So the next time if a Chat txt doesn't go thru cuz of no data connection, it'll automatically send it using sms/mms network connection
