Water damaged phone recovery
What do I do about a phone with water damage? i need to recover the phone number to return it to its owner. It's an iPhone 10s with no visible cracks or scuffs. All iv'e gotten out of it was a dead battery sign and purple and green lines on the display. I would like to find the owner by looking on iTunes, but it dosen't pop up anywhere. What can i do to see it on iTunes, and if i can't than what can I do to fix it/ find the owner?
