Expert Review & Rating
Market Position in 2026
In 2026, the Samsung Galaxy M31s is firmly a budget-tier entry on the used or refurbished market, primarily appealing to users seeking a very affordable device for basic communication. Its hardware, particularly the chipset and display technology, has been significantly surpassed by modern budget and mid-range alternatives.
The Best Features
The most compelling feature of the Galaxy M31s remains its substantial 6000 mAh battery capacity, which, even in 2026, suggests impressive longevity for light to moderate usage on a single charge. The Super AMOLED display, despite its standard refresh rate, still offers vibrant colors and deep blacks that can be more appealing than some LCD panels found in current ultra-budget phones. The inclusion of a dedicated microSDXC slot is also a notable advantage, allowing for cost-effective storage expansion. The ability to record 4K video with both front and rear cameras was a strong point at launch and still provides a higher resolution option than some contemporary entry-level devices.
The Compromises
The Exynos 9611 (10 nm) chipset is the most significant compromise; in 2026, it struggles with anything beyond basic applications and will likely exhibit noticeable slowdowns and longer load times compared to modern processors. The 60Hz display refresh rate is a notable drawback, as even many budget phones now offer 90Hz or 120Hz panels, leading to a less fluid scrolling experience. Furthermore, the 25W charging speed, while adequate for its time, is considerably slower than the rapid charging solutions available in newer devices, meaning longer wait times to fully replenish the large battery. Software support is also a critical concern, as the device is unlikely to receive further major Android updates or regular security patches, posing potential security and compatibility issues.
Performance & Daily Usage
The Exynos 9611 chipset will handle basic communication and social media, but will show its age with more demanding apps or multitasking. UI responsiveness may be sluggish, and application load times will be extended. Gaming performance will be limited to very casual titles. The 6000 mAh battery will still provide extended screen-on time for light users. The Super AMOLED display offers good visual quality for media consumption. Camera performance, while capable of 4K, will be constrained by the older sensor technology and processing, especially in challenging lighting conditions.
Buying Advice
The Samsung Galaxy M31s is a viable option for individuals on an extremely tight budget who prioritize battery life above all else and require a secondary device for calls and messaging. However, for users seeking a smoother experience, faster charging, or ongoing software support, investing in a newer budget smartphone is strongly recommended.
Frequently Asked Questions (FAQs)
In 2026, the Samsung Galaxy M31s is primarily suitable as a very affordable secondary device or for users with minimal performance demands, due to its outdated chipset and likely end-of-life software support. Its large battery remains a strong point for basic usage.
Based on the 64 MP main sensor with an f/1.8 aperture and the lack of advanced imaging processors found in newer phones, the camera's low-light performance will likely be limited, producing images with noticeable noise and reduced detail compared to modern devices.
