iphone crashed, lost all pictures/text messages
HELP!
My iphone 6 randomly crashed a couple days ago and I lost 2,500 pictures. Today, my iphone crashed AGAIN and it erased ALL of my text messages, and now when I get a text it doesn't alert me or show up on my homescreen even though it's set in my message notifications as such. My iPad still shows the messages, but once i answer a text on my phone, the conversation disappears from my iPad. Anyone have any idea what is going on, or if my texts/photos are salvageable?!
