The Samsung Galaxy Quantum 2 is Samsung's security-focused flagship, launched in partnership with SK Telecom and built around an Infinity-O Dynamic AMOLED 2X display, an in-display fingerprint sensor, the Qualcomm Snapdragon 855+ chipset and quantum cryptography technology. Below you will find the full specifications, camera details, battery capacity and price of this powerful smartphone.
Samsung Galaxy Quantum 2 design and display
The phone runs One UI based on Android 11 and features a large 6.7-inch Quad HD+ (1,440x3,200 pixels) Dynamic AMOLED 2X display, giving it a sharp, high-resolution panel for media and gaming. In terms of build, it measures 161.9x73.8x8.1 millimeters and weighs 176 grams, keeping it slim despite its sizeable screen. Samsung offers the Galaxy Quantum 2 in three color variants: White, Gray and Light Violet, so buyers have a few options to match their taste.
Performance, RAM and storage
Under the hood, the Qualcomm Snapdragon 855+ SoC handles speed and multitasking, making the device well suited to demanding apps and everyday performance. The handset comes with 6GB of RAM and 128GB of internal storage, which can be expanded up to 1TB using a microSD card, so storage is unlikely to be a concern for most users. What truly sets this phone apart is its security: an in-display fingerprint sensor and quantum cryptography technology work together to protect data on the device, a feature reflected in the handset's Quantum branding and its launch alongside SK Telecom.
Camera setup
On the back, there is a triple rear camera setup led by a 64-megapixel primary sensor with an F/1.8 aperture, paired with a 12-megapixel secondary sensor (F/2.2) and a 5-megapixel third sensor (F/2.4). The camera setup supports 10x digital zoom and OIS. For selfies, the front houses a 10-megapixel camera with an F/2.2 aperture.
Battery and connectivity
A 4,500mAh battery powers the device and supports 25W fast charging. Note that the retail box includes only a 15-watt charger, so a 25-watt charger must be purchased separately. Connectivity options include NFC, Wi-Fi 802.11 AC, a USB Type-C port, Wi-Fi Direct and two stereo speakers.
