One of the earliest missing things I noticed was the lack of “Visual Voicemail”. On an iPhone you can see a list of your voicemails along with who they are from. It is easy to pick and choose which to listen to and is much more convenient than what feels like an incredibly old approach of following voice guided prompts and pressing buttons.
Luckily I found with a quick search that there is a free AT&T application for Android that provides Visual Voicemail. An install later with no configuring needed and it is up and running.
I found in the settings that there is an option for transcriptions. This is a feature recently added to iOS, but I had never had luck with it. I activated Android transcriptions and will see how they play out.
This was an unanticipated need, but luckily was a quick fix.
