I’m with you: I love the SE, and recently upgraded from the 2 to the 3. And it may not be absolutely definite, but from what I’ve read, the SE 3 will likely be the last iPhone with the Home button, as disappointing as that is (I much prefer TouchID to FaceID). So I wouldn’t get your hopes up.
I used to get several spam calls a day. I started blocking any number that even remotely seemed like spam, and now I probably have over 200 on the list. It took a while, maybe a few months, but the calls gradually decreased until they stopped almost altogether. Now I may get one or two a month at the most.
