Why aren't my photos saving with date as title, just IMAG# since update.?

Photos no longer saved with date as title, just IMAG# since update.

I really, really want this back. Does anyone know a way to do this? Dropbox uploads all my photos from my phone and changes the date created and modified to the day they were uploaded. Now I dont' know when any of my photos were taken once they are on my computer.
