Android Central Question
If both parties have the read receipt function on where it shows delivered and read in the text, if I delete it without opening it, will it say read on the senders side or will it stay on delivered?
Looks like RCSIs the OP talking about basic default SMS messages, and/or about RCS?
AgreeNot sure why the OP needs what they are asking for, but if they are using RCS then I think they'd need to first disable that and go back to just plain old SMS, and then also make sure read SMS receipts aren't on, as others have suggested. Then, presumably there'd be no indication back to sender for if an SMS message was received/read.
