As mentioned earlier, I've had mine for a few days now. I've been through every menu, deleting unwanted pre-installed apps, turning off notifications and background data use, and setting it up the way I like it. None of the cons in my list below are a deal breaker, though. I'm really happy with it.
Pros:
Photos are really good!
Calls are clear and not garbled (my S7 was getting horrible for calls)
It's a bright screen even changed to dark mode
Oh and it's fast! I'm using it as a "hot spot" for laptop since we don't get reliable internet service where I live.
The transfer of data was seamless. Download the transfer app on your old phone and set them side by side, and after a bit all is transferred.
Cons:
I don't like the placement of the camera lenses. They stick out from the back and the edge is sharp. The case I ordered case should be here today and should fix that.
The placement of the volume up/down and the on/off button are too close. But I'm sure I'll get used to it.
I hate apps that I can't disable or un-install.
USB-C cable. I'm used to Kindle, tablet and phone using the same cord.
