On my previous phones (HTC Hero, Motorola Photon Q) when I locked an individual text message before deleting that thread, the locked texts remained (because they were locked!). But on my GS3, the lock does nothing. A screen asks if I'm sure I want to delete locked messages, but gives me no way to say no. So I can delete none, all or delete by checking them individually. The lock has no other purpose.
Does anyone have a fix for this?
NOTE: I am using the stock SMS app that came on the phone. I tried GoSMSPro, but the problem remained.
