random question I know but - we got a new(ish) mobile phone and there is no option to lock specific messages to make sure we don't accidentally delete them. It seems this is no longer an option on HTC (android) mobiles. Does anyone know of a app that allows you to do this?

 

in case someone else has had this problem I found this article https://joyofandroid.com/best-sms-app-for-android/

and installed a new messaging app and now I can lock messages to protect them from accidental deletion.
