Questions about this item

Does the phone include a charger or do I need to supply my own USB-C power adapter?

The box contains only the handset and a USB-C cable; you must provide a USB-C power adapter that supports USB Power Delivery for fast charging.

Will my existing Nano SIM card work in this device?

Yes, the handset uses a standard Nano SIM slot, so any active Nano SIM from your current carrier will fit and connect to 5G where available.

How can I confirm the 120 Hz Dynamic AMOLED 2X panel is running at its peak refresh rate?

Open Settings, tap Display, choose Motion smoothness and select Adaptive; the screen will then switch up to 120 Hz automatically when content supports it.
