I've only dropped my phone in the toilet once in my life, but was caught many times in big down pouring rains. Fortunately never had any water damages, but IP67-IP68 gives a peace of mind. Removable batteries are a thing of the past now, so why not fully water resistant makes sense.
That's not z11 for sure. If you let the video run its length an stop, at the last frame is quite visible the front camera of the phone which is nothing like the z11 but its exactly as the z17 Tenaa shot that was released.
Looks like the release if this phone is imminent, and I'll finally upgrade my old smarty.
[deleted post]If there isn't a worthy comment then one shouldn't post. Nevertheless, it seems most manufacturers are going the IP route whether high-end or not. This is a route which should have been taken a long time ago. Most females have water damaged phones. Despite manufacturers taking a while to get on-board the IP train, better late than never.
