1. What phone is this?

This is the Samsung Galaxy M12, model family SM-M127F, with 4GB RAM, 64GB storage, Dual SIM and Green finish. Samsung officially sold a Green 4GB/64GB version as SM-M127F/DSN.

2. Is Green an official Samsung color?

Yes. Samsung officially lists Green, along with Black and Light Blue, for the European Galaxy M12.

3. Is 4GB RAM + 64GB storage an official configuration?

Yes. Samsung’s exact Green product page specifies 4GB memory and 64GB storage.

4. Is the phone 4G or 5G?

It is a 4G LTE smartphone. It does not support 5G.

5. Does it support Dual SIM?

Yes. Samsung specifies Dual SIM using Nano-SIM cards.

6. Can both SIMs be used while a microSD card is installed?

Yes on the official European version. Samsung specifies SIM 1 + SIM 2 + microSD, meaning the microSD slot is dedicated rather than hybrid.

7. Does it support eSIM?

Samsung’s Galaxy M12 product specification lists physical Nano-SIM slots and does not document eSIM support for this model.

8. Does it support microSD?

Yes.

9. What is the maximum microSD capacity?

Samsung officially specifies up to 1TB.

10. How much of the 64GB storage is available on the European Green model?

Samsung lists approximately 48.1GB available storage before user-installed content, with the rest used by system software and preloaded data.

Exynos 850 performance

11. Which processor powers the Galaxy M12?

The Samsung Exynos 850. Samsung’s regional launch documentation confirms the Galaxy M12 uses this processor.

12. What process technology does the Exynos 850 use?

8nm FinFET.

13. How many CPU cores are there?

Eight.

14. Which CPU cores are used?

Eight Arm Cortex-A55 cores.

15. What is the maximum CPU speed?

2.0GHz.

16. Is the current MyWorldPhone CPU line technically right?

Your page says four 2.0GHz A55 cores plus another four 2.0GHz A55 cores. That totals the correct eight Cortex-A55 cores, but a cleaner specification is simply Octa-Core Cortex-A55, up to 2.0GHz.

17. Which GPU does it use?

Mali-G52 MP1.

18. Should your page say only Mali-G52?

It is broadly correct, but Mali-G52 MP1 is Samsung Semiconductor’s more precise specification.

19. What RAM technology does the chipset support?

LPDDR4X.

20. What storage technology does the Exynos 850 platform support?

eMMC 5.1.

Display

21. How large is the display?

6.5 inches measured as a full rectangle. Samsung gives approximately 6.4 inches accounting for rounded corners.

22. What display type does it use?

Samsung calls it a PLS TFT LCD.

23. Should the page say PLS IPS?

I would change it to Samsung’s official wording: PLS TFT LCD. Your live table currently says PLS IPS.

24. What is the display resolution?

720 × 1600 HD+.

25. What is the aspect ratio?

Approximately 20:9 based on the resolution. Your existing value is reasonable.

26. Does it support a 90Hz refresh rate?

Yes. Samsung specifically markets the Galaxy M12 with a 90Hz refresh rate.

27. Is it an AMOLED display?

No. It is LCD, not AMOLED.

28. Is the display curved?

No. It uses a conventional flat Infinity-V display.

29. How many colors does the display support?

Samsung specifies 16 million colors.

30. Does Samsung publish an official screen-to-body percentage?

Samsung’s official product specification does not publish the 81.9% figure currently used on your page. I would either remove it or mark it as a calculated/third-party figure.

Design & dimensions

31. What are the official dimensions?

164.0 × 75.9 × 9.7mm.

32. What does the European Green version weigh?

214g.

33. Is the current 221g figure necessarily correct?

No. Your page says 221g, but Samsung’s official Green European model is 214g. Other regional M12 versions were heavier, so this is another reason to verify the exact full sales code.

34. How does Samsung describe the exterior design?

Samsung describes a metallic finish and micro-pattern design with curved edges for grip.

35. Does Samsung officially call the rear glass?

No. The Galaxy M12 is not marketed as a glass-backed premium device.

36. Does it have a side-mounted fingerprint sensor?

Yes.

37. Does it use an in-display fingerprint sensor?

No.

38. Does it have a physical proximity sensor?

Samsung lists Virtual Proximity Sensing.

39. Does it have a virtual light sensor?

The European specification lists Virtual Light Sensing.

40. Is there an official IP rating?

Samsung’s official Galaxy M12 specification does not publish an IP water/dust-resistance rating. Do not advertise the phone as waterproof or IP-rated.

Four.

42. What is the main-camera resolution?

48MP.

43. What is the main-camera aperture?

f/2.0.

44. Does the main camera autofocus?

Yes.

45. Does the main camera have OIS?

No. Samsung explicitly says Rear Camera OIS: No.

Camera zoom & video

51. What is the maximum rear-camera digital zoom?

Samsung specifies up to 10× digital zoom.

52. Does it have optical zoom?

No dedicated telephoto/optical-zoom camera is listed.

53. Does it have a telephoto camera?

No.

Yes.

55. What is the maximum rear-video resolution?

Full HD 1920 × 1080 at 30fps.

56. Does the camera record 4K?

No. Samsung’s official maximum recording resolution is Full HD.

57. Does it record Full HD at 60fps with the camera?

Samsung’s camera-recording specification says 30fps. Do not confuse that with the phone’s ability to play Full HD video at 60fps.

58. Does it have OIS video stabilization?

No physical OIS.

59. Does Samsung advertise HDR photography?

Your existing third-party specification lists HDR, but the official Samsung product page mainly emphasizes the individual camera functions. I would not make HDR a headline specification.

60. Does the camera support portrait-style background blur?

The 2MP depth camera is designed to help separate subjects from backgrounds in supported portrait modes.

Front camera

61. What is the selfie-camera resolution?

8MP.

62. What is the selfie-camera aperture?

f/2.2.

63. Does the selfie camera autofocus?

No. Samsung lists front autofocus as No.

64. Does the front camera have OIS?

No.

65. Does the phone have a front flash?

No dedicated front flash is specified.

Battery — important regional issue

66. What battery capacity does the Green European SM-M127F have?

Samsung’s exact Green 4GB/64GB SM-M127FZGVEUA page specifies 5000mAh typical, with a 4900mAh rated minimum.

67. Why does MyWorldPhone currently say 6000mAh?

Because Samsung also sold a regional Galaxy M12, notably in India and other markets, with a 6000mAh battery. Your page appears to mix specifications from different regional M12 versions.

68. Which battery value should this exact Green page use?

If your physical Green unit carries the European sales code corresponding to SM-M127FZGVEUA/EUE, use 5000mAh. If your actual imported box is a different 6000mAh region, use 6000mAh. Verify the complete Samsung sales code before publishing.

69. Does your existing page currently contradict itself on battery size?

Yes. The product marketing and specification table say 6000mAh, while the existing FAQ says 5000mAh.

70. Is the battery removable?

No. Samsung states it is non-removable.

71. What charging speed does Galaxy M12 support?

Up to 15W Adaptive Fast Charging.

72. Does it support wireless charging?

Samsung does not list wireless charging for Galaxy M12.

73. Does it support reverse wireless charging?

No manufacturer support is documented.

74. Does it support 25W Samsung Super Fast Charging?

No. Its supported device charging rate is up to 15W.

75. What battery runtime does the 5000mAh European model advertise?

Samsung gives up to 20 hours LTE internet, 20 hours Wi-Fi internet, 19 hours video playback, 92 hours audio playback and 49 hours LTE talk time under its test conditions. Real use varies.

Network & SIM

76. Is the Galaxy M12 factory unlocked?

Your unit is sold as unlocked by MyWorldPhone, but network activation still depends on the exact regional model, bands and carrier provisioning.

77. Should the title say “GSM Unlocked”?

I would remove GSM. The device supports GSM, WCDMA and LTE; modern compatibility is not accurately described by the old GSM-versus-CDMA distinction.

78. What LTE bands does Samsung list for the European Green version?

Samsung lists FDD LTE B1/B2/B3/B4/B5/B7/B8/B12/B17/B20/B26/B28/B66 and TDD LTE B38/B40/B41.

79. Is your current MyWorldPhone LTE band list complete?

No. Your page currently lists only B1/B3/B5/B7/B8/B38/B40/B41, which is substantially narrower than Samsung’s official European Green specification.

80. Why does the exact regional code matter for carrier compatibility?

Different Galaxy M12 regional variants can have different band sets and features. The complete Samsung sales code/CSC is therefore more reliable than the shortened SM-M127F family name.

Wi-Fi, Bluetooth, NFC & positioning

81. What Wi-Fi does the actual European Galaxy M12 use?

Samsung specifies 802.11 b/g/n on 2.4GHz.

82. Does it support 5GHz Wi-Fi?

Not on the official European Galaxy M12 device specification, despite the Exynos 850 chipset itself having broader theoretical Wi-Fi capability. Device implementation matters.

83. What Bluetooth version does it use?

Bluetooth 5.0.

84. Does it support Wi-Fi Direct?

Yes.

85. Does the European Green Galaxy M12 have NFC?

Yes. Samsung’s exact Green European product page lists NFC.

86. Is the current “NFC: No” on your page therefore wrong?

If your physical stock is the European Green version, yes. This is another region-specific field that should be checked against the full box code.

87. Which positioning systems are supported?

GPS, GLONASS, BeiDou and Galileo.

88. Does it support dual-frequency GNSS?

Samsung does not advertise dual-frequency positioning for Galaxy M12.

USB & audio

89. What USB connector does it use?

USB Type-C.

90. What USB version is it?

USB 2.0.

91. Does it support MHL wired video output?

No. Samsung explicitly lists MHL: No.

92. Does it have a 3.5mm headphone jack?

Yes.

93. Does it have stereo speakers?

No. Samsung explicitly lists Stereo Support: No.

94. Should you describe the loudspeaker as stereo?

No. Use single loudspeaker + 3.5mm headphone jack.

95. Does it support Samsung Smart Switch?

Yes. Samsung lists Smart Switch PC synchronization.

Software & package

96. What software did Galaxy M12 launch with?

Your page correctly reflects an original Android 11 / One UI-era launch configuration.

97. Is Android 11 still “the latest version of Android,” as the existing FAQ says?

No. That sentence is outdated and should be removed. Samsung’s official support page even provides later Galaxy M12 manuals for Android 12 and Android 13.

98. Did the Galaxy M12 receive later software support?

Yes. Samsung currently hosts an Android 13 user manual for the SM-M127F family, showing that later software revisions were supported. The software actually installed on inventory may depend on update status.

99. Is your Package Content section correct?

No. It currently names Samsung M21 M127F, lists a separate battery, and automatically lists headphones. The product is a Galaxy M12 and its battery is non-removable. Package contents can also differ by sales region.

100. What is the single most important thing to verify before rewriting this SKU?

Check the complete Samsung sales code on the physical Green 4GB/64GB box. If it corresponds to Samsung’s European Green version, the correct battery/NFC/weight/network profile is 5000mAh, NFC Yes, 214g and the broader European LTE band set.
