Accidentally Deleted text on IPhone 5c. How do I undo or Recover them?

I deleted a bunch of text on my IPhone in Notes. The iPhone was put to never auto lock. I put the iPhone in my pocket with notes open while it's on never auto lock and when I took it out of my pocket, most of the text were gone. The whole note is not deleted, but MANY texts deleted.

how do I undo it?

See if your fiends have the texts still… Pretty sure it's gone forever on your phone

Yes, go to see if your frineds still have the texts copy. If no, you can try to use third party utility such as iPhone data recovery. It is able to recover files from iPhone without backup. Furthermore, you can choose what you want to recover and preview before recovery. Recommended one: Tenorshare iPhone Data Recovery
