Quick take
The HMD Fusion is a practical mid-range 5G phone with an unusual modular angle. Its core hardware is conventional: a 90 Hz HD+ screen, Snapdragon 4 Gen 2 chipset, expandable storage and a large battery. The difference is the exposed two-way connector on the back, which allows compatible Smart Outfits to communicate with the phone.
That modular system is useful only if the matching accessories are available where you live, so it should be treated as a bonus rather than the sole reason to buy. The repairable construction and microSD slot are the more broadly useful long-term advantages.
Design, dimensions and Smart Outfits
HMD lists the Fusion at 164.15 × 75.5 × 8.32 mm and 202.5 g. The phone carries an IP54 rating, meaning it is designed to resist limited dust ingress and splashes, but it is not intended for immersion.
A transparent Casual Outfit is included in the box. Optional Smart Outfits go further: the two-way connector can support a camera ring light, physical gaming controls or added rugged protection. HMD also offers an open development toolkit for people who want to design their own compatible hardware. Accessory availability varies by market, so buyers should check the local HMD store before relying on a particular Outfit.
Display
The 6.56-inch panel has a 720 × 1612 resolution, a 20:9 aspect ratio and a 90 Hz maximum refresh rate. That faster refresh rate should make scrolling and interface animation look smoother than on a basic 60 Hz screen.
Resolution is the main compromise. HD+ is less sharp than Full HD+ at this size, particularly for small text and high-resolution media. HMD quotes 600 nits of peak brightness, which is adequate on paper for everyday use but not positioned as a high-brightness flagship display.
Performance, RAM and storage
Qualcomm’s Snapdragon 4 Gen 2 (SM4450) provides the processing platform and 5G modem. It is aimed at efficient everyday performance rather than high-end gaming. Messaging, navigation, streaming and routine apps fit the hardware’s intended use; demanding 3D games will benefit from moderate graphics settings.
The official specification lists 6 GB of RAM and 128 GB of internal storage. HMD also advertises virtual-memory options, but virtual RAM uses storage and is not equivalent to physical memory. A microSD card of up to 1 TB can be added, an important advantage for offline video, music and photos.
Cameras
The rear camera system combines a 108 MP autofocus main sensor with a 2 MP depth sensor and LED flash. HMD lists Smart EIS for stabilization. The secondary sensor assists with depth information rather than providing an ultrawide or telephoto view, so the camera system is best understood as a single versatile main camera with support hardware.
The 50 MP front camera uses fixed focus. HMD’s overview highlights Selfie Gestures and selfie slow motion, features intended to make hands-free capture easier. Megapixel numbers alone do not establish image quality, and this article does not claim hands-on camera testing.
Battery and charging
A 5000 mAh battery powers the phone. HMD quotes up to 65 hours under its own stated test conditions, but real endurance will vary with signal strength, brightness, refresh rate and workload.
Charging reaches 33 W and supports USB Power Delivery and Quick Charge. The retail package includes a USB-C cable but no wall adapter, so buyers who do not already own a compatible charger should budget for one. The USB-C port operates at USB 2.0 speed and supports OTG accessories.
Software and update commitment
The HMD Fusion launched with Android 14. HMD promises two operating-system upgrades and three years of security updates. Its detailed support note describes a cadence that changes over time, so the important purchase consideration is the total support period rather than assuming every patch arrives monthly throughout the full term.
That policy is respectable for a value-focused phone, although buyers comparing longer ownership periods should check the current support pages of competing models before deciding.
Connectivity, audio and security
Connectivity includes 5G, nano-SIM and eSIM, NFC, Bluetooth 5.1 and Wi-Fi a/b/g/n/ac with HMD describing Wi-Fi 6 readiness. Positioning support covers GPS/A-GPS, GLONASS, BeiDou and Galileo.
Audio features include aptX Adaptive, OZO Audio and two microphones. Authentication is handled by a fingerprint reader integrated into the side power key, with face unlock also available.
Repairability and what can be replaced
HMD describes the Fusion as a Gen2 repairable design. The display, back cover, battery and charging port are among the parts intended for replacement through designated partners in supported markets. Self-repair programs and parts availability differ by country, so the practical benefit depends on local coverage.
This approach can reduce the cost and waste associated with common failures. It also complements the modular accessory idea: the phone is designed to be adapted and maintained rather than treated as a sealed, fixed object.

Price and availability
HMD does not present one universal current price on the international product page, and retailer pricing can vary by country and remaining stock. The company’s current notice says the device is not available in Germany, France, Italy, the Netherlands or Belgium. Readers should confirm local stock, warranty and Smart Outfit availability before purchasing.
The official HMD specifications page is the best place to confirm regional variants and package contents.
Strengths and trade-offs
Strengths: expandable storage, 33 W charging, NFC, eSIM, a 50 MP selfie camera, repairable construction and the modular accessory connector. The included transparent outfit also provides immediate basic protection.
Trade-offs: the display is only HD+, the 2 MP secondary rear sensor is limited, USB data speed is 2.0 and the wall charger is sold separately. The Smart Outfit concept also depends on regional accessory support.
Alternatives to consider
If expandable storage and repairability matter most, compare current mid-range devices that publish parts and software-support commitments clearly. Readers considering a more conventional budget 5G phone can also review the NUU X10 5G specifications. For a performance-focused alternative with a very different priority set, see the Realme GT 8 Pro specifications.
The right choice depends less on headline megapixels and more on display sharpness, software-support length, accessory availability and the repair options offered in your market.
Verdict
The HMD Fusion specifications describe a capable everyday 5G phone whose strongest ideas sit outside the processor race. The combination of microSD expansion, repairable parts and functional Smart Outfits gives it a distinct identity.
Its HD+ screen and basic secondary rear camera keep expectations grounded. It makes the most sense for buyers who value serviceability and modular accessories, provided local support and Outfit availability are confirmed first.
