DWP

Hello,
DW is my default SMS app.
How to proceed to transfer SMS sent and received by DW to my new phone ?
Notice : SMS sent and received by DW do not appear in SMS stock app so using a legacy SMS backup tool is useless.
Thank you.

Have you tried Backups Manager? Settings/Backup & Restore/Backups Manager. I don't use the SMS facility but it might be included in Backups Manager.

Thank you for your help.
DW does not store SMS in the system database but in its own database so legacy system backup tools are useless.
Backup function in DW does not backup own SMS database but parameters only.
That is why I am asking here but it seems DW is a quite dead app as no support is provided by devs.
