I typically miss notifications that I've got a missed call because all that shows up on the lockscreen is a green arrow. Especially if I have lots of notifications before and/or after the missed call. I've deleted all the customized apps and themes I've installed and still can't get the missed calls to show up at the top and list who called.
Is there anyway to fix this or is this just how Samsung Galaxy phones show missed calls?
Usually the notification isn't that small. Try settings > apps > phone > notifications > missed call. Is it set to "alert" or "silent?" My thought is you might have it on silent which makes the notification not important and smaller.
