1. Which exact phone is this?
This is the Samsung Galaxy S21 5G SM-G9910, with 8GB RAM, 256GB storage and Phantom Pink finish. Samsung Hong Kong officially sold this exact combination.
2. Is Phantom Pink an official Samsung color?
Yes. Samsung officially offered the Galaxy S21 in Phantom Pink.
3. Was Phantom Pink available with 256GB?
Yes. In Samsung Hong Kong’s official launch lineup, Phantom Pink was offered on the 256GB S21.
4. Is 8GB RAM official?
Yes. Samsung Hong Kong lists 8GB RAM for both 128GB and 256GB Galaxy S21 variants.
5. What RAM generation does the S21 use?
Samsung’s S21 launch material specifies 8GB LPDDR5 RAM.
6. Is 256GB storage official?
Yes. Samsung Hong Kong officially lists 256GB internal storage.
7. Does it support a microSD card?
No. Samsung explicitly says microSD is not supported.
8. Should the listing say UFS 3.1?
Your current table says UFS 3.1, but Samsung Hong Kong’s first-party retail specification does not state the storage-generation number. If you want strictly manufacturer-grounded copy, I would simply use 256GB Internal Storage.
9. What is the exact model number?
SM-G9910. Samsung Hong Kong’s support portal specifically identifies this model as Galaxy S21 5G.
10. Is SM-G9910 the same hardware variant as SM-G991U1?
No. They are different regional versions with different network configurations. Your current page incorrectly uses SM-G991U1 bands in an SM-G9910 listing.
Snapdragon 888 performance
11. Which processor does the SM-G9910 use?
The Hong Kong Galaxy S21 SM-G9910 uses Qualcomm Snapdragon 888.
12. Does this model use Exynos 2100?
No. Remove Exynos 2100 from this exact SM-G9910 page. Samsung Hong Kong explicitly lists Snapdragon 888.
13. What process node is Snapdragon 888?
5nm.
14. What is the maximum CPU speed?
Up to 2.84GHz. Samsung Hong Kong lists 2.84GHz / 2.4GHz / 1.8GHz CPU groups.
15. What CPU family does Snapdragon 888 use?
Qualcomm Kryo 680.
16. What is its CPU architecture?
It is a 64-bit CPU subsystem built around Qualcomm Kryo 680, including Arm Cortex-X1 technology.
17. Which GPU does it use?
Qualcomm Adreno 660.
18. Which AI processor does Snapdragon 888 include?
Qualcomm Hexagon 780, part of the sixth-generation Qualcomm AI Engine.
19. Which 5G modem platform is built into Snapdragon 888?
The platform uses the Snapdragon X60 5G Modem-RF System.
20. Should your technical table show both Snapdragon and Exynos?
No. For this exact SM-G9910, show only the Snapdragon configuration. The current dual-platform table is misleading.
Display
21. How large is the screen?
6.2 inches measured as a full rectangle.
22. What display technology does it use?
Dynamic AMOLED 2X.
23. Is the S21 display flat or curved?
The standard Galaxy S21 has a flat display.
24. What is the display resolution?
2400 × 1080 FHD+.
25. What is the pixel density?
Samsung Hong Kong specifies 421 PPI.
26. What refresh rate does it support?
Up to 120Hz adaptive refresh.
27. Is 120Hz permanently locked?
No. Samsung describes an adaptive refresh rate that adjusts based on displayed content. Samsung launch material gives a roughly 48–120Hz range for the S21.
28. Does it support HDR10+?
Yes. Samsung’s S21 launch specification identifies HDR10+ support.
29. How bright can the display get?
Samsung product materials advertise up to approximately 1300 nits peak brightness.
30. What should I do with the ~87.2% screen-to-body figure on MyWorldPhone?
I would remove it. Samsung’s Hong Kong specification does not publish that percentage, so it is better not to mix a third-party calculated figure into the manufacturer specification.
Display protection & body
31. What protects the front display?
Corning Gorilla Glass Victus.
32. Is Gorilla Glass Victus also used on the back?
No. Samsung’s own product material specifies that Victus applies to the front display of the standard S21.
33. What material is the rear cover?
The standard S21 uses a polycarbonate/plastic rear panel rather than a glass rear.
34. What type of frame does it use?
A metal/aluminum frame with Samsung’s Contour Cut camera design.
35. What are the exact dimensions?
151.7 × 71.2 × 7.9mm.
36. How much does the SM-G9910 weigh?
Samsung Hong Kong gives 169g for the S21.
37. Should the listing show 171g for mmWave?
No. That value belongs to other regional mmWave versions. The Hong Kong SM-G9910 is a 169g Sub-6 model.
38. What IP rating does it have?
IP68.
39. What water-resistance test does Samsung publish?
Up to 1.5m of water for 30 minutes under Samsung’s stated IP68 conditions.
40. Is the phone waterproof?
No. IP68 is a laboratory ingress-resistance rating, not an unconditional waterproof guarantee.
Rear camera system
41. How many rear cameras are there?
Three.
42. What is the main camera?
A 12MP wide camera with f/1.8 aperture, Dual Pixel autofocus and OIS.
43. Is the top MyWorldPhone “Rear Camera 12MP” field correct?
It is correct if that field means main camera resolution. But it is ambiguous because the phone also has a 64MP rear camera. If your store uses the field to represent the highest rear resolution, it should be 64MP instead.
44. What is the telephoto/high-resolution camera?
A 64MP f/2.0 camera used for Samsung’s 3× Hybrid Optic Zoom system.
45. Does Samsung call it 3× optical zoom?
Samsung’s official S21 launch terminology is 3× Hybrid Optic Zoom, not a conventional 3× optical telephoto lens.
46. What is Space Zoom?
The S21 supports up to 30× Space Zoom / Super Resolution Zoom, incorporating digital zoom beyond the 3× Hybrid Optic level.
47. What is the ultrawide camera?
12MP, f/2.2, approximately 120° field of view.
48. Does the main camera have OIS?
Yes.
49. Does the 64MP camera have OIS?
Samsung’s S21 launch specifications list OIS on the 64MP tele/high-resolution camera as well.
50. Does it have a fourth rear camera?
No. The Galaxy S21 has a triple rear-camera system.
Front camera & video
51. What is the selfie-camera resolution?
10MP. Your top MyWorldPhone field is correct.
52. What is the front-camera aperture?
f/2.2.
53. Does the selfie camera autofocus?
Yes. Samsung specifies Dual Pixel autofocus.
54. What is the maximum rear-video resolution?
8K at 24fps.
55. Does it support 4K60 video?
Yes. Samsung’s S21 specifications support 4K recording up to 60fps.
56. Can the front camera record 4K?
Yes; Samsung Galaxy S21 documentation supports 4K selfie recording.
57. What is Director’s View?
A Samsung camera feature for monitoring and switching among different camera perspectives while recording.
58. What is Single Take 2.0?
Samsung’s AI-assisted capture mode that creates multiple photos/video outputs from a single shooting sequence.
59. Does it support Super Steady video?
Yes.
60. Can 8K footage be used to extract still images?
Yes. Samsung promoted 8K Video Snap for extracting high-resolution still frames from captured footage.
Battery & charging
61. What is the battery capacity?
4000mAh typical.
62. Is the battery removable?
No. It is an integrated battery.
63. What is the maximum wired charging rate?
25W Super Fast Charging.
64. What wired charging standard does Samsung use?
Samsung documents USB Power Delivery-based Super Fast Charging; its S21 support page recommends USB PD 3.0 for Super Fast Charging.
65. Does it support wireless charging?
Yes.
66. What is the maximum official wireless charging speed?
15W Fast Wireless Charging.
67. Is the 15W wireless pad currently recommended on the page suitable?
Yes—unlike many phones we reviewed, a 15W wireless pad is appropriate for this model if the pad is Qi-compatible. The S21 supports up to 15W wireless charging.
68. Does it support reverse wireless charging?
Yes. Samsung calls the feature Wireless PowerShare.
69. Should the page state “4.5W reverse wireless”?
For strictly Samsung-grounded retail copy, I would simplify it to Wireless PowerShare: Supported, since Samsung Hong Kong’s launch sheet does not publish that wattage.
70. Is a 20W wall charger ideal?
It can work, but it is below the phone’s 25W maximum. A verified 25W USB PD/PPS Samsung-compatible charger is the better primary recommendation.
SIM & exact SM-G9910 network
71. How many physical SIMs does the Hong Kong SM-G9910 support?
Two physical Nano-SIM cards.
72. Is the current “Single SIM and/or eSIM or Dual SIM” row correct?
No. That is generic multi-region S21 information. For this Hong Kong SM-G9910, Samsung’s official specification says Nano-SIM + Nano-SIM.
73. Should eSIM be advertised on this exact listing?
I would not advertise eSIM for this SKU unless you verify it on the exact inventory. Samsung Hong Kong’s SM-G9910 launch specification specifically presents two physical Nano-SIMs.
74. Does it support Dual SIM Dual Standby?
Yes.
75. Which 5G bands does Samsung Hong Kong officially list?
For this Hong Kong configuration, Samsung lists n1, n5, n41, n78 and n79, all Sub-6GHz.
76. Does SM-G9910 support n71 or mmWave n260/n261 according to Samsung Hong Kong?
Those are not in Samsung Hong Kong’s official SM-G9910 band list. Your page currently copied n71/n260/n261 information from SM-G991U1, so remove it.
77. Which LTE FDD bands does Samsung Hong Kong list?
B1, B2, B3, B4, B5, B7, B8, B12, B13, B18, B19, B20, B25, B26 and B28.
78. Which LTE TDD bands are official?
B34, B38, B39, B40 and B41.
79. Which WCDMA/3G bands are official?
B1, B2, B5 and B8.
80. Should CDMA2000/EVDO remain in the table?
No. Your current table mixes old CDMA/EVDO specifications from another regional model. Replace it with the exact SM-G9910 Hong Kong network table above.
Wi-Fi, Bluetooth, NFC & USB
81. What Wi-Fi standard does it support?
Wi-Fi 6 / 802.11ax, plus legacy a/b/g/n/ac standards.
82. Does the exact Hong Kong S21 support 6GHz Wi-Fi 6E?
Samsung Hong Kong lists 2.4GHz + 5GHz Wi-Fi, not 6GHz. So do not add Wi-Fi 6E to this listing.
83. Does it support MIMO?
Yes. Samsung lists MIMO and 1024-QAM.
84. Does it support Wi-Fi Direct?
Yes.
85. What Bluetooth version does the SM-G9910 S21 use?
Bluetooth 5.0.
86. Does it support NFC?
Yes.
87. What satellite-positioning systems are supported?
Samsung Hong Kong lists GPS/A-GPS, GLONASS, BeiDou and Galileo.
88. What USB connector does it use?
USB Type-C.
89. Is USB 3.2 Gen 1 reasonable?
Yes. Samsung’s official S21 product specifications in other regions identify USB 3.2 Gen 1 for the S21 hardware. If you want maximum regional conservatism, “USB Type-C” alone is sufficient.
90. Does it support Samsung DeX?
Yes. Samsung Hong Kong currently lists the Galaxy S21 among phones supporting Samsung DeX, including wired and wireless display use.
Audio, sensors, software & package
91. Does it have stereo speakers?
Yes.
92. Does Samsung officially support high-resolution audio?
Yes. Samsung Hong Kong lists PCM up to 32-bit/384kHz and DSD 64/128.
93. Does it have a 3.5mm headphone jack?
No. Audio accessories connect by USB-C or Bluetooth.
94. What fingerprint system does it use?
An ultrasonic under-display fingerprint sensor.
95. What other sensors does Samsung list?
Accelerometer, barometer, gyroscope, geomagnetic sensor, Hall sensor, light sensor and proximity sensor.
96. What operating system did it launch with?
Android 11.
97. Can it run newer Android versions?
Samsung’s current Hong Kong support page for SM-G9910 provides manuals through Android 15, showing that the model received support for substantially newer software than its launch version. Installed software on an individual unit may vary depending on updates.
98. Does it support Samsung Wallet/Samsung Pay?
Yes. Samsung Hong Kong lists the Galaxy S21 among supported Samsung Wallet devices.
99. Does the retail box include a wall charger and headphones?
Samsung’s S21 box policy does not include a charger plug or earphones by default; a USB Type-C data cable is included. Regional contents can vary, so physical stock should always be verified.
100. What is the most serious problem on this MyWorldPhone page?
The network/platform table. The page is an SM-G9910 Phantom Pink product but currently mixes SM-G991U1 mmWave bands, CDMA/EVDO, Exynos specifications, U.S. regional data and Hong Kong Snapdragon data into one table. That needs to be corrected before almost anything else.
