Screen and Design

Galaxy A71

The differences between Samsung devices begin with the size and type of the screen. The Galaxy A71 features a 6.7-inch display with Super AMOLED Plus technology, while the M31 offers a smaller, 6.4-inch panel and opts for Super AMOLED.

The Plus version featured on the A71 can guarantee 50% more sub-pixels than its predecessor on the M31. The successor of the Galaxy A70 should lead not only by the size of the screen but also by the sharpness of the display.

Moreover, there is also a small difference between smartphones in resolution, since the M31 uses a Full HD+ version of 2340 x 1080 pixels, while the A71 features 2400 x 1080 pixels.

Regarding the design, the Galaxy A71 features a hole in the screen to house the front camera in the center of the panel. The Galaxy M31, on the other hand, features a drop-shaped notch-mounted selfies camera.

To accommodate the photo set, the two cell phones use a rectangle in the top corner at the back of the phone. The A71 has four colors, blue, black, silver, and gray, while the Galaxy M31 has black, blue, and red options.


M31 Quad camera

The quadruple-camera is present on both Samsung cell phones. Both the Galaxy A71 and the M31 use a 64 MP main camera, plus a macro lens and a depth sensor, both with 5 MP. The difference between the devices is found in the ultra-wide camera. The sensor that captures larger images has 12 MP in Galaxy A71 and 8 MP in Galaxy M31, which can set up an advantage for the photos of the Galaxy A member. Both still have a 32 MP front camera.

The videos recorded by the two mobile phones can be recorded at 4K (3840 x 2160 pixels) at 30 frames per second. Both also allow portrait mode and dynamic focus to adjust the background blur level.

Performance and Storage

Samsung Galaxy M31

Another aspect that marks the difference between the devices is the processor. The Galaxy M31 adopts the Exynos 9611 (octa-core up to 2.3 GHz), a chip manufactured by Samsung itself. On the A71, the Snapdragon 730 (octa-core up to 2.2 GHz) from Qualcomm comes on the scene.

The 128 GB memory is present in the datasheet of both devices, as well as the support for the microSD card that expands the storage up to 512 GB. Another common specification is 6 GB RAM.

The Game Booster is also a tool present in both handsets and is responsible for optimizing the gaming experience. It learns the patterns of use to optimize aspects such as battery, temperature, and memory, which can improve the performance of cell phones during games.



The Galaxy M31 should take a prominent position in this regard. The 6,000 mAh capacity of the Galaxy M line representative can get the best of the 4,500 mAh of Galaxy A71. Samsung promises that the M31 can offer two hours more than the 24 hours of the A71 when it comes to video playback. Also, for audio, Galaxy M31 can handle 119 uninterrupted hours, while Galaxy A71 should provide only 107.

If M31 is rated, A71 should get the best of fast loading support. The first model has 15 W recharging, while the second has 25 W power. Both have USB-C input for the chargers.

Android Version

The Galaxy M31 and Galaxy A71 leave the factory with Android 10. Recently, Samsung announced that both cell phones should receive the update to Android 11, the latest version of Google’s system, in March 2021. Android 11 brings news such as screen recording, a grouping of conversation notifications, and more data protection.

Additional Features

Proximity payment

While the Galaxy A71 features an on-screen fingerprint sensor, the M31 features a reader located on the back of the smartphone. They also bring facial recognition as biometrics to unlock the device. A difference that highlights the Galaxy A71 is the presence of NFC technology, responsible for making proximity payments. The two smartphones also feature 5 GHz Wi-Fi and Bluetooth 5.0.
