Nothing Phone (3a) (128GB / 8GB RAM) specifications and in-depth review

Nothing Phone (3a) (128GB / 8GB RAM)

Manufacturer: Nothing

The Nothing Phone (3a) is a mid-range Android smartphone running Android 15, built around a 6.77″ OLED/AMOLED panel with a 120Hz refresh rate, 387 ppi pixel density, and Always-On Display support. The device measures 163.5 mm tall and 8.4 mm thick, weighs 201 g, and carries an IP64 rating for basic dust and water resistance.

Under the hood, the Nothing Phone (3a) relies on the Qualcomm Snapdragon 7s Gen 3 — a 4 nm octa-core chipset paired with 8 GB of LPDDR5 RAM and 128 GB of internal storage. The triple rear camera system combines 50 MP and 50 MP main sensors alongside an 8 MP shooter, with OIS and 2x optical zoom, while video capture reaches 4K at 30 fps. Connectivity covers 5G, Wi-Fi 6, Bluetooth 5.4, NFC, and USB Type-C, and the 5000 mAh battery supports 50W wired fast charging without wireless charging.

Pros
  • The 6.77-inch OLED display supports both HDR10 and HDR10+, offers a 120Hz refresh rate, 240Hz touch sampling, and a 5,000,000:1 contrast ratio, making it well-suited for smooth scrolling and high-dynamic-range content
  • The triple rear camera system includes optical image stabilization, 2x optical zoom, phase-detection autofocus, and a broad set of manual controls covering ISO, exposure, focus, and white balance
  • 50W wired fast charging paired with a 5000 mAh battery provides rapid top-ups without sacrificing capacity
  • The Snapdragon 7s Gen 3 is built on a 4 nm process with an octa-core big.LITTLE configuration and HMP support, enabling efficient multithreaded workloads within a 5W thermal envelope
  • Connectivity is comprehensive, covering 5G, Wi-Fi 6, Bluetooth 5.4, NFC, dual SIM, GPS, and Galileo navigation in a single device
  • Android 15 brings a wide range of privacy controls including app tracking blocking, clipboard warnings, and camera and microphone access management
Cons
  • Wireless charging is not supported, limiting charging flexibility
  • No 3.5 mm headphone jack is present, and none of the high-fidelity Bluetooth codecs — aptX, aptX HD, aptX Adaptive, aptX Lossless, or LDAC — are available
  • The USB Type-C port is limited to USB 2.0, restricting wired data transfer speeds
  • No charger is included in the box despite the 50W fast charging capability
  • There is no external memory slot, meaning the 128 GB of internal storage cannot be expanded
  • The display lacks branded damage-resistant glass, which may raise concerns about scratch and impact resilience
Who is this for?

This device is a solid fit for everyday users who want a capable all-rounder with a large, vibrant screen and versatile camera system. The 6.77-inch OLED display with 120Hz refresh rate and HDR10+ support makes it well-suited for media consumption, casual gaming, and general browsing. The triple rear camera with OIS, phase-detection autofocus, and extensive manual controls will appeal to users who enjoy hands-on photography without needing RAW output. Those who rely heavily on mobile connectivity will appreciate the dual SIM 5G support, Wi-Fi 6, and NFC, while the 5000 mAh battery with 50W fast charging suits people with full-day usage patterns who need quick top-ups rather than overnight charging.

Who is this NOT for?

Users who depend on wireless charging or USB high-speed data transfer will find this device limiting, as it lacks wireless charging entirely and its USB Type-C port is capped at USB 2.0. The absence of aptX, LDAC, and any high-fidelity Bluetooth codec makes it a poor match for audiophiles or anyone invested in wireless hi-res audio, particularly since there is no 3.5 mm jack to fall back on. The non-expandable 128 GB storage may also frustrate users who store large volumes of locally saved media. Additionally, those looking for advanced safety or biometric features — such as crash detection, satellite SOS, or 3D facial recognition — will not find them here, making this a less suitable option for users who prioritize those capabilities.

Final Verdict

The Nothing Phone (3a) presents a well-rounded specification set that covers the core needs of most day-to-day smartphone users. Its large OLED display with HDR10+ support, 120Hz refresh rate, and a capable triple camera system with OIS give it genuine strengths in media and photography, while the Snapdragon 7s Gen 3 chipset and 5000 mAh battery with 50W fast charging ensure the device holds up through extended use. That said, the lack of wireless charging, USB 2.0 speeds, no high-fidelity Bluetooth codec support, and non-expandable storage are real trade-offs that narrow its appeal for more demanding users. For those seeking a feature-complete daily driver with solid connectivity, a versatile camera, and dependable battery performance, the Nothing Phone (3a) is a coherent and practical choice within its category.
