Yes. Xiaomi says the 512GB model supports up to 16GB of UFS Storage Extension.

9. Does it support microSD?

No.

10. Is all 512GB available to the customer?

Arm Immortalis-G925.

18. What maximum GPU speed does POCO advertise?

Up to 1.6GHz.

About 2 nits.

46. How many colors does the display support?

Approximately 68.7 billion colors with 12-bit color depth.

f/2.2.

64. What is its sensor size?

1/4 inch.

65. What is its field of view?

Approximately 112°.

66. Does the ultrawide autofocus?

No. Xiaomi specifies fixed focus.

67. Does the main camera autofocus?

Yes.

68. Is there a physical telephoto camera?

No.

69. Why does POCO advertise “2× optical-level zoom”?

It is a high-resolution crop from the main camera, not a separate 2× optical telephoto lens. Xiaomi’s technical FAQ says the actual camera positions are 0.6× and 1×, while the product page markets 2× as optical-level quality.

70. What is the maximum photo zoom?

Xiaomi lists a range up to 60× digital zoom.

Selfie camera & video

97. Which Bluetooth codecs are officially supported?

Xiaomi lists SBC, AAC, LDAC, LHDC 3/4/5, LC3, Auracast, ASHA, MIHC and LE Audio. It explicitly says aptX, aptX HD and aptX Adaptive are not supported.
