Most, if not all, of my text messages before December 2019 have disappeared. I did not delete them, and my phone was set so that they would not be deleted. As I research the situation, I realize I am not the only one. I'm fairly certain that they are archived somewhere, because one app I used, which promised to recover deleted messages, did in fact bring many up, but then wanted a rather large fee before before I would be allowed to restore them. I did not pay.
I don't know if this issue stems from Samsung, Google (the messenger I used), or Verizon (my carrier), but I need to get back many of the text messages.
Somebody help, please.
As I know, such samsung data recovery tool can help us scan out all data on Samsung phone, including the deleted or disappeared messages before they are overwritten. It's free to scan data. You don't need to buy it. But before using it, you need to root your samsung phone, enable USB debugging on it. Rooting is not that easy.
