I use it almost exclusively/when it makes sense to. But so many people are surprised that I use it.
Part of it is because I was an android user until about 2015 and that was always a feature on the phones I had. I also use it because I have small hands and the biggest iPhone so I find it easier to type one-handed sometimes.
Speaking of typing, the new iPhone typing update has been horrible for me at least who uses an older iPhone. I mean I have an iPhone 11 Pro Max but only 12 and above get the better predictive text I think. Seems like now the predictive text is way worse. It always auto corrects to something that doesn’t make sense and does it too often. They added the thing where it underlines an autocorrected word so you can easily revert it but it’s just annoying to have to revert it.
