Automatically deleted text messages

[Android Central Question]

My LG V20 is automatically deleting a lot of text messages. How can I retrieve them

Is the "phone" doing the deletes?

Or is your SMS app doing the deletes?
Some SMS apps have a scheduled maintenance setup where it deletes "old" messages each month. If your SMS app has this feature, you should be able to change the schedule, update the definition of "old", or just turn off the feature.
