Charging

The phone is great, BUT, when I charge with a lead, it turns itself off, which is annoying. When I use a wireless charger it states on. I needed the phone when it arrived, so didn't return it. I hope that's the only issue I might have with it, as I can live with that.

Another great phone! One wee issue though...

The phone and its features are great! i fully support not providing a charger, but many people my have upgraded from an older phone such as the Galaxy S9 like myself would have found it better to have a usb - usb-c cable instead, or have an adaptor provided for the usb c cable provided, to be able to connect to a usb charger? And also maybe an adaptor to fit a 3/4 jack headphones to the usb-c adaptor too? The lack of these brought the value down a bit for me im afraid...
