> Top notch waterproof

You mean those stupid plastic flaps with the gaskets that came unglued and prevented the flaps from even closing properly?

And after marketing it as an underwater camera, they later backpedaled and said "waterproofing was tested in a standby state under laboratory conditions, do not attempt to use the phone underwater"?

Waterproofing, maybe. Top notch waterproofing, absolutely not.

This. Girlfriend had that phone. The device and their after-sales service was completely garbage. Sony failed to repair the unplugging flaps, even after multiple service attempts. And every single time, they did complete factory reset on the phone to replace the flaps (!!!).

They replaced my water damaged Z3 very quickly, but this was in the EU where consumer rights are stronger.

My phone flaps are fine, but I charge it using the magnetic connector, so I rarely open them.

I've never opened those since I bought the phone. Installed the sim and SD card and then never touched it again.

That's why I listed magnetic charging as a key feature ;)

Then they didn't go and make the mistake of trying to slim too much for the next gen in the Z4 compact. The thing has incremental improvements on all the features you mentioned and battery life is just as good as it was before.
