Phone will capitalize all letters of name of someone?

My phone for a while would autocapitalize all the letter of my s.o name. Ex.) MINGA

To solve this problem, I went to her contact and changed her name to Dominga (her full name). I don’t think it matters what you change it to. But then after that it wouldn’t recognize her name and capitalize the first letter. So I then changed it back to Minga and it fixed both issues. Also I texted myself her name a handful of times and would select the correct suggested version to teach my phone to stop picking the wrong one. So

it could be a combo of both solutions but in turn the contacts method worked best for me. Hope this helped!
