I have a Redmi 4A that I bought while in China a few months ago.
It works great in English but seems to only offer a choice of only 12- vs. 24-hour time format and American date format, mm/dd/yyyy.
For all English speakers who aren't American this format is very confusing. All my other devices let me change to dd/mm/yyyy format. But so far I can't find a way to do this on my phone.
Android version is 6.0.1 MMB29M and MIUI version is 22.214.171.124(MCCCNED)
