The Bluefox NX1 is a truly pint-sized smartphone sporting a 4-inch display with a Dynamic Island-style feature, all housed within a slim 4.9 cm-wide body. Despite the phone’s remarkably small size, Bluefox managed to fit a 3,000 mAh battery, though some compromises were necessary to maintain affordability.

Smartphones with a 6.3-inch display are already considered compact by today’s standards. For instance, the Apple iPhone 16, with its 6.1-inch display, is amongst the smallest smartphones currently available. Defying this trend, the ultra-compact Bluefox NX1 features a tiny 4-inch screen that is similar in size to the iPhone 5’s panel.

Measuring just 10 x 4.9 x 1.2 cm (3.9 x 1.9 x 0.5 in), the NX1 is even smaller than the iPhone 5 thanks to its thinner bezels. Its thicker body allows Bluefox to include a 3,000 mAh battery, which should provide reasonable battery life given the tiny display and modest hardware. The IPS panel offers a resolution of 1,168 x 540, a peak brightness of 500 nits, and a refresh rate of 60 Hz. Aside from the display, the company had to make a few compromises to keep prices low.
 


The Bluefox NX1 is powered by the MediaTek Helio G81, a chipset that debuted back in 2019. It comes with up to 8 GB of memory and 128 GB of storage, expandable using a microSD card. Surrounding the 5 MP front-facing camera is a Dynamic Island-style feature capable of showing charge status and incoming calls. On the back, the phone is equipped with a 21 MP main shooter featuring a Sony IMX230 sensor. Whilst the NX1 ships with Android 15, Bluefox has yet to disclose details related to update support.

Price and availability

The Bluefox NX1 recently launched in China, with prices starting at ¥599 (approx. $83) for the base model with 4 GB of RAM and 64 GB of flash storage. A higher-tier model with 8 GB of RAM and 128 GB of storage is also available for ¥799 (approx. $111). A global version is expected to follow in late June.
