I would highly recommend this app. It did exactly as it says, removed my two unread messages in 5 seconds. You do have to pay to be able to read these messages but it is free if you just want to delete them (after a couple of days of googling and doing tasks like deleting all my messages I was happy to delete those two)
Very specific app and it does exactly what it says on the tin. My Nova Launcher was reporting 2 unread text messages but I couldn't see them. I ran this app and it showed them from about 4 months ago and marked them as read. Problem solved.
Amazing Don't know how they do but it worked in seconds... Hope will not have any issues later. Thanks
Wowed!!! Amazing app, cleared my hidden sms in under 5 mins.
Hangs Nexus 5X (Marshmallow) with Hangouts - this finds the unread SMS but hangs on "processing". Have to force stop, manually set Hangouts back to default SMS app and then the only way to get rid of unread SMS is to delete it.
Xperia Z5 dual 👍 Worked perfectly! Thanks a lot..
