1. Which exact phone is this?

This is the Samsung Galaxy S23 Ultra 5G, model family SM-S918B, with 12GB RAM, 256GB internal storage and Phantom Black finish. Samsung officially sold this exact RAM/storage/color combination in supported regions.

2. Is 12GB RAM + 256GB storage an official Samsung configuration?

Yes. Samsung’s official regional buying pages specifically list 12GB/256GB for the Galaxy S23 Ultra.

3. Is the official color simply “Black”?

Samsung’s proper marketing name is Phantom Black.

4. What is the exact model family?

SM-S918B / SM-S918B/DS, depending on the regional SKU identifier. Samsung Support explicitly identifies SM-S918B/DS as Galaxy S23 Ultra.

5. Is this the U.S. SM-S918U model?

No. SM-S918B is an international/global model family, distinct from U.S. SM-S918U/U1 variants.

6. Does that distinction matter?

Yes. Network bands, SIM configuration, firmware, carrier certification and package contents can differ by regional model.

7. How much RAM does this exact SKU have?

12GB.

8. How much internal storage does it have?

256GB.

9. What storage technology does the S23 Ultra use?

UFS 4.0. Samsung’s official regional product information identifies UFS 4.0 storage for the Galaxy S23 Ultra.

Snapdragon 8 Gen 2 for Galaxy

11. Which chipset powers the S23 Ultra?

Snapdragon 8 Gen 2 Mobile Platform for Galaxy.

12. Is this the standard Snapdragon 8 Gen 2?

It is a Samsung-optimized “for Galaxy” version with higher peak CPU frequency than Qualcomm’s standard reference configuration at launch.

13. What process node does it use?

4nm. Samsung’s SM-S918B documentation identifies the platform as a 4nm 64-bit octa-core processor.

14. How many CPU cores does it have?

Eight.

15. What CPU clock configuration does Samsung publish?

Samsung gives 1× 3.36GHz + 4× 2.8GHz + 3× 2.0GHz.

16. Why does your current page split the four 2.8GHz cores into A715 and A710 groups?

That is a more detailed third-party-style architecture description. It is technically consistent with the platform, but Samsung’s cleaner first-party specification is simply 1×3.36 + 4×2.8 + 3×2.0GHz.

17. What GPU does it use?

Adreno 740. Samsung’s own regional Galaxy S23 Ultra product information identifies the GPU as Adreno 740.

18. Does it support hardware ray tracing?

Yes. Samsung promoted real-time hardware-accelerated ray tracing as part of the S23 series gaming platform.

19. Does the phone have vapor-chamber cooling?

Yes. Samsung enlarged the vapor-chamber cooling system across the S23 series.

20. Is the Snapdragon chipset the same in every S23 Ultra market?

Samsung launched the S23 series globally around Snapdragon 8 Gen 2 for Galaxy, rather than splitting S23 Ultra markets between Snapdragon and Exynos.

Display

21. How large is the display?

6.8 inches measured in the full rectangle.

22. What panel type does it use?

Dynamic AMOLED 2X.

23. Is the display flat?

No. Samsung describes it as a QHD+ Edge display, although the S23 Ultra reduced the curvature compared with previous Ultra generations to create a larger flatter writing/viewing area.

24. What is the resolution?

Samsung officially writes it as 3088 × 1440 QHD+.

25. Is the 1440 × 3088 figure on your page wrong?

It is the same pixel matrix written in portrait orientation, but I would use Samsung’s official 3088 × 1440 ordering.

26. What is the refresh-rate range?

Adaptive 1–120Hz.

27. Should the page simply say 120Hz?

It is technically true, but Adaptive 1–120Hz is more precise and more impressive.

28. What touch-sampling rate does Samsung advertise?

240Hz in Game Mode.

29. What is the peak display brightness?

Samsung advertises up to 1750 nits.

30. Does it have Vision Booster?

Yes. Vision Booster dynamically improves visibility and contrast in bright conditions.

Yes. Samsung’s launch specification includes Enhanced comfort alongside Vision Booster.

32. Does it support HDR?

Yes. Samsung identifies HDR10+ support for the Galaxy S23 Ultra display and video ecosystem.

34. Does the rear also use Gorilla Glass Victus 2?

Yes. Samsung states Victus 2 is used on both the front and back of the S23 series.

35. Is the ~89.9% screen-to-body figure an official Samsung specification?

Samsung’s current first-party SM-S918B product pages I checked do not publish that percentage. Your live value appears to be third-party/calculated data, so I would remove it if you want manufacturer-grounded copy.

Body, dimensions & durability

36. What are the official SM-S918B dimensions?

163.4 × 78.1 × 8.9mm.

37. What is the exact SM-S918B weight?

Samsung’s detailed SM-S918B regional specification gives 233g.

38. Why do some Samsung launch materials say 234g?

Samsung published 234g on some launch-region tables and 233g on later exact SM-S918B product specifications. For an SM-S918B-specific listing, I would use 233g.

39. What frame does it use?

Armor Aluminum.

40. What glass does it use?

Gorilla Glass Victus 2 front and back.

41. What water/dust rating does it have?

IP68.

No. Samsung specifically says resistance is not permanent and advises against beach or pool use.

44. Is the S Pen also IP68?

Samsung says the Galaxy S23 Ultra’s built-in S Pen supports the same IP68 water/dust-resistance rating.

45. Is Phantom Black a special edition?

No. Phantom Black is one of the regular launch colors, alongside Green, Cream and Lavender. Online-exclusive colors included Graphite, Sky Blue, Lime and Red.

Yes. The S Pen is physically integrated into the Galaxy S23 Ultra.

Yes; the S Pen’s Air Actions rely on motion-sensing and Bluetooth integration.

54. Is your current “Remote Camera Control” feature accurate?

Yes. That is a good feature to keep.

55. Should the S Pen be highlighted higher on the page?

Yes. It is one of the strongest differentiators between the S23 Ultra and most conventional flagship phones.

Rear camera system

56. How many rear cameras are there?

Four actual rear cameras.

57. Are your image ALT tags saying “quad cameras” correct?

Samsung’s 100× Space Zoom combines the 10× optical telephoto with digital zoom and AI Super Resolution.

71. Is 100× optical zoom?

No. The physical optical zoom tops out at 10×; beyond that Samsung uses digital/AI processing.

72. Should the product page say “100× optical zoom”?

No. Use:

3× Optical Zoom | 10× Optical Zoom | Up to 100× Space Zoom

5000mAh typical.

87. What is the rated/minimum battery capacity?

Samsung gives approximately 4855mAh rated/minimum.

Samsung’s standard Gulf package specifically says the S23 Ultra does not include a travel adapter.

92. Does it support wireless charging?

Yes—Fast Wireless Charging 2.0 up to 15W.

93. Does it support reverse wireless charging?

Yes. Samsung calls it Wireless PowerShare.

94. Should your page claim exactly 4.5W reverse wireless?

I would change it to “Wireless PowerShare: Supported.” Samsung’s official S23 Ultra launch material confirms the feature but does not use that wattage in the product specification I verified.

SIM, networking & connectivity

95. Does SM-S918B support Dual SIM?

Yes. Samsung’s exact SM-S918B specifications list Dual SIM.

96. Does it support eSIM?

Yes. The SM-S918B tray configuration supports two physical Nano-SIMs or physical SIM + eSIM, depending on setup and region.

97. Does SM-S918B support mmWave 5G?

The official SM-S918B band list I checked is Sub-6 5G, not the U.S. mmWave bands currently pasted into your page.

98. What Wi-Fi does it support?

Wi-Fi 6E on 2.4GHz, 5GHz and 6GHz, with HE160/MIMO support.

99. What Bluetooth version does it use?

Bluetooth 5.3.

100. What other flagship connectivity/features are included?

The SM-S918B supports NFC, Ultra Wideband, Wi-Fi Direct, GPS/GLONASS/BeiDou/Galileo/QZSS, USB Type-C 3.2 Gen 1, Samsung DeX, Wireless DeX, ultrasonic in-display fingerprint recognition, Samsung Knox/Knox Vault and stereo audio.

The phone launched with Android 13 / One UI 5.1, but Samsung committed the Galaxy S23 series to four generations of OS upgrades and five years of security updates. Samsung’s current SM-S918B support page now provides manuals for later Android versions, so your retail page should describe Android 13 as the launch software, not imply that every unit remains on that version today.

Factory-unlocked status does not guarantee activation on every U.S. carrier. This is particularly important here because SM-S918B is the international Sub-6 model, whereas your current page mixes in U.S.-specific CDMA and mmWave data. Compatibility depends on the exact model, supported LTE/5G bands, IMEI eligibility, VoLTE/IMS provisioning, eSIM support, carrier certification and current carrier policies.
