Mobile Price BD: Samsung Galaxy A31 – Overview Full Features


Welcome to Mobile Price BD, Introducing the Samsung Galaxy A31, Capture life’s big moments with the stunning 48MP quad camera on the sleek Samsung Galaxy A31. Immerse yourself in a vibrant Infinity-U display, while a long-lasting battery fuels your non-stop world. Performance you can trust, plus ample storage.

Display and Design:

The Galaxy A31 boasts a stunning 6.4-inch Super AMOLED display, bringing your content to life with vibrant colors and deep blacks. Its Full HD+ (1080 x 2400) resolution ensures sharp visuals, while the 411 PPI pixel density keeps everything smooth and crisp. Eye Comfort Shield reduces blue light emission for fatigue-free viewing, letting you enjoy movies and games for longer.

The sleek design features a geometric pattern on the back, available in eye-catching hues like Prism Crush Black, Blue, Red, and White. Crafted from durable polycarbonate, the body feels lightweight (185g) and comfortable in your hand. An in-display fingerprint sensor provides secure and seamless unlocking.

Camera Capabilities:

The Galaxy A31 packs a quad-camera setup on the back, headlined by a 48MP main sensor for crisp, high-resolution shots. Capture the bigger picture with the 123° ultra-wide lens, or get up close and personal with the 5MP macro camera. A dedicated 5MP depth camera lets you achieve stunning Live Focus effects with adjustable background blur. Video recording maxes out at 1080p, while front-facing 20MP camera ensures selfie satisfaction.


While not a powerhouse, the Galaxy A31 packs a decent punch for its price point. Its octa-core MediaTek Helio P61 processor clocks in at 2.0 GHz, delivering smooth performance for everyday tasks like browsing, social media, and even some light gaming. The PowerVR Rogue GE8320 GPU handles graphics, offering decent visuals for casual games and multimedia. 4GB or 6GB of RAM keeps things running smoothly when multitasking, though demanding apps might cause a slight stutter.

Storage Options:

The Samsung Galaxy A31 offers ample storage for your digital life, with two internal options: 64GB and 128GB. Need more? Don’t fret! A dedicated microSD card slot supports expansion up to a whopping 512GB, letting you store an ocean of photos, videos, and apps. Choose the variant that suits your needs, with 4GB RAM accompanying the 64GB storage and 6GB RAM paired with the 128GB option. This flexible storage setup ensures you can download freely and worry less about deleting precious memories. Go forth and capture, store, and enjoy!

Software and User Interface:

The Galaxy A31 packs a punch when it comes to software. Originally launched with Android 10 and One UI 2.1, it received a generous upgrade to Android 12 and One UI 4.1 in 2022. This means you get a modern, redesigned interface with improved stock apps and a Color Palette feature for personalization. Enhanced privacy controls and the April 2022 security patch keep your data safe. Don’t forget Edge Screen and Edge Lighting for convenient shortcuts and notifications. While it may not be the latest flagship, the A31’s software experience is surprisingly feature-rich and up-to-date, making it a worthy contender in the mid-range market.

Battery and Charging:

The Samsung Galaxy A31 boasts a powerful 5000mAh battery, ensuring you stay connected for longer. This lithium-ion behemoth resides comfortably sealed within the phone’s body, eliminating the need for messy battery swaps. When it’s time to recharge, the Galaxy A31 supports 15W fast charging, taking you from empty to 100% in under two hours. This means less time tethered to the outlet and more time for what matters. Whether you’re streaming videos, gaming, or simply staying in touch, the Galaxy A31’s battery is built to power through your day, so you can focus on what you love.

Connectivity and Network:

The Samsung Galaxy A31 packs a comprehensive connectivity punch despite its budget-friendly price tag. Dive into blazing-fast 4G LTE speeds for seamless streaming and downloads, or stay connected with dual-SIM functionality. Wi-Fi, with support for dual-band (2.4GHz and 5GHz) connections, ensures smooth browsing and file transfers. Share content effortlessly with Bluetooth 5.0, offering improved range and stability. Get lost in your adventures with GPS, GLONASS, and BeiDou navigation systems guiding your way. And for wired connections, the microUSB port handles charging and data transfer.


The Samsung Galaxy A31 packs a punch without breaking the bank. Super AMOLED display delivers vibrant visuals, while the triple-lens rear camera captures stunning photos day or night. Octa-core processor ensures smooth performance for gaming and multitasking, and the long-lasting battery keeps you powered up all day.

For those seeking a stylish and capable smartphone without the premium price tag, the Galaxy A31 is a compelling option. Its sleek design, in-display fingerprint sensor, and ample storage make it a well-rounded package for everyday users. Whether you’re snapping selfies, browsing social media, or streaming your favorite shows, the Galaxy A31 won’t disappoint
