OTA updates are most likely going to work in most of the devices bought at our website and they should not change system sate ex. removing multi-language and google apps.

However, there are devices where OTA will not work, we usually inform about it on the product page, in the "ROM" section. If you'll not be able to make automatic updates, you may always try to make manual system update, which may require some skills or tools (ex. ADB) installed on your computer. It may also remove system customisations installed before ex. multi-language support. For more info you may ask us a question from product page.

NFC will most likely work on the most of the devices bought on our website. 

Exception are some, but not all, devices sold with unlocked bootloader, due to Global rom installation ex. Xiaomi. Some other devices with Global rom installed on original rom, and unlocked bootloader shouldn't have problems with NFC payments - ex. Realme devices. Root can also cause NFC banking applications not work, but our store in current time don't sell rooted devices at all (state for January 2024).

If you have doubts if your device will have NFC payments working you should ask us every time by product questions available at product page or checks questions of the other customers at the bottom of the product page.

Three core components
100% full carbon architecture
Lightweight design
The space-grade T800H carbon fiber is widely used in the Xiaomi MIX Fold 4 phone.
This material is used in the floating plate of the Xiaomi keel hinge, the screen support lining, and the battery compartment lining of the middle frame, with a total area of up to 33552mm².
The lightweight carbon fiber material reduces weight and improves the strength of core components. The tensile strength of T800H carbon fiber is as high as 5500MPa, and with the
unidirectional belt process, the impact resistance of the middle plate is increased by 300% after the five-layer precision compression mold.
*300% improvement in impact resistance compared to aluminum alloy medium plate.

supports 4×4 MIMO antenna technology / HPUE / HO RxD
Note (1): Whether or not 5G is supported depends on the local operator's network; When two telecom cards are used, the non-network card needs to activate the HD voice service, and
the service cannot be used if it is not activated or the local network does not support the HD voice service.
Note (2): Radio and television does not support 2G and 3G networks; Radio and television does not support MMS services;
Note (3): TD-SCDMA (mobile 3G) is not supported; CDMA 2000 EVDO (Telecom 3G) is not supported;
Note (4): Dual-SIM dual-pass only supports some frequency band combinations of 5G+5G and 5G+4G in SA mode, and supports high-definition voice services of China Mobile, China Unicom, China Telecom, and radio and television.

Note (5): This function supports the activation of calling cards for Tiantong satellite services. Currently, only telecom services are supported, and China Unicom services will be supported after deployment by carriers.
