Deleted texts keep reappearing

[AC Question]

1st LG4 died, factory defect. Lost all photos. When I turn on Wi-Fi for new one all deleted texts reappear. Cannot figure out how to stop it.

Welcome to Android Central! Do you mean that on the new phone, when you turn on wi-fi, texts that you deleted on the previous phone's Messaging app reappear on the new phone's Messaging app? What happens if you delete those message threads again. Do they come back the next time you turn the phone on?
