Sadly that is already multiple years old (2, at this point) which makes it only 1 year younger than the iPhone SE (And the SE is actually more powerful based on benchmarks).

I don't want to go into "who supports hardware longer" or "how long phones last" but I don't think this is a true successor.

I have one. It's kind of heavy for its size though and slippery due to the rounded edges. The touch display is not the best in terms of responsiveness.

Plus for someone considering an iPhone SE, the XZ2 doesn't have iOS.

One thing I'll note though: Surprisingly my XZ2 did get the full upgrade to Android 10 from Android 9. So that's pretty great considering it's 2 years old.

It's only slightly smaller and 50% thicker than an iPhone 8.
