Frequently Asked Questions:
Does this phone come with a charger?
No—only the device and protective case. Any standard USB‑C PD charger (25 W recommended) will fast‑charge it.
Is it truly unlocked?
Yes, this SM‑F721U model is unlocked and compatible with AT&T, T‑Mobile, Verizon, and global carriers.
Is the cover screen functional?
Absolutely—use it for notifications, quick replies, music controls, timers, AR emojis, and even framing self‑timer shots without unfolding.
Can I upgrade the storage?
No—128 GB is fixed. If you need more space, consider cloud storage or offloading photos regularly.
How is battery life?
Expect a full day of moderate use (e.g., social media, calls, a few videos). Heavy 5 G usage or extended camera sessions will drain it faster.
