I have a case that I opened for abuse verbally and physically. Unfortunately my phone fell in water and I lost all necessary evidence through messages. How can I retrieve the messages?

Your phone did fall over, but your SD card never really breaks. Just go to an electronic store or something. You might wanna call your phone dealer such as T-Mobile or Verizon. Perhaps they might help. Plus, you can just go online and check your history on your phone. Just have to sign in to your account.
