How I can change date format

[JOSIF JORDANOV1]

I am trying to find a way to change date format.
I have S4 Mini and S5 Mini - they both cync in Dropbox, but with different date format,
so it is truly hard to arrange the photos by date.
S4 Mini have a date format, but I am not able to find it in S5 Mini's menu.

Remove Automatic date and time thick if u want to set date manual by urself if l understand ur question well...

I have the same issue and turning off "Automatic date and time" does not help. It always shows MM/DD/YY as in 11/17/16. This makes no sense to my Canadian or European brain.
Any other ideas on how this can be changed?
