Phone wakes up a few minutes after every text message. Can I make that stop? I have an iPhone 6S with the latest version of iOS. For a couple of months now whenever I receive a text message and put the phone back down it will wake up again for no apparent reason.

Sometimes it seem to randomly do so without a text message, but the text message one is reproducible.

Anyone have any idea why that might be and if I can stop it?
Settings -> Notification -> Message -> Repeat alarm -> Never
