Last week I bought a galaxy A52 5G phone. I have always set up a custom text message notification sound for my children in their contact profile - I want to know immediately if they text me. I am very disappointed that the custom sound isn't saved - if the conversation thread is deleted the sound is also deleted and then the sound reverts to the same sound as all my other contacts. Does anyone else share my frustration? I wouldn't have bought a Samsung phone if I would have known this....it is that important to me.
