How do I add text to a photo using my Samsung S9?

[Android Central Question]

I have been an android user for two weeks and frustrated at the lack of simplicity to photos. I just want to add a simple text to a photo. I open it in Gallery and I only have a option of writing on the photo with my finger - which is horrible!
Why no simple T for text/caption add?
This is a Samsung S9 new in August 2018.

Look in Play for Photo Stamper. Many of them have logo stamp and text stamp as well as time, date, location, etc.
