I purchased a m3 note some days before. When I go to set time, it display only one format - month/day/year. i cannot change it to other formats. On my previous phone, it had all formats like dd/mm/year, mm/dd/year, year/mm/dd etc. Please provide us all the other formats. the current format is confusing for me.
