Galaxy M31 to Buy – Prices and Availability in Australia

The Samsung Galaxy M31 remains a viable budget option in the Australian market, though buyers must navigate a landscape dominated by refurbished units rather than new stock. Released in early 2020, this mid-range Android smartphone distinguished itself with a massive 6,000mAh battery and quad-camera configuration that earned praise for everyday photography. As of 2026, Samsung has discontinued official new unit production, shifting availability to secondary and refurbished channels across Australian retailers.

Understanding where and how to purchase a Galaxy M31 in Australia requires examining current stock levels, pricing trends, and the device’s position relative to newer alternatives. The landscape has shifted significantly since the phone launched at AUD 479 for the base 6GB/128GB configuration, with contemporary prices reflecting both its age and the availability of more recent budget smartphones from Samsung and competitors.

For Australian consumers weighing this purchase, several factors merit consideration: software support status, battery health in older units, and whether newer alternatives offer better long-term value despite higher initial costs.

Software Updates and Support Status

Android Version Progression

Samsung committed to delivering two major Android OS updates for the M-series along with three to four years of security patches. The Galaxy M31 received these updates according to the following timeline, based on Australian rollout records from Sammobile and community forums.

1. March 2020 — Launched with Android 10 and One UI 2.0
2. December 2020 – February 2021 — Upgraded to Android 11 (One UI 2.5)
3. October 2022 – January 2023 — Final major OS update to Android 12 (One UI 4.1)
4. July 2023 — Final security patch released for Australian units via FKI CSC rollout

Current Support Status

As of 2025, Samsung has officially ended support for the Galaxy M31. No further software updates—including security patches—have been released since mid-2023. The Samsung Australia support page confirms the device has reached end-of-life status within the manufacturer’s support cycle.

For technically inclined users, custom ROMs such as LineageOS remain available through developer communities like XDA Forums. However, installing custom software voids any remaining warranty, may cause compatibility issues with Australian carrier networks, and requires advanced technical knowledge. Most general consumers should treat the device as unsupported for modern applications.

Major retailers including JB Hi-Fi and The Good Guys no longer carry the Galaxy M31 in any condition.

Is Galaxy M31 Worth Buying in 2025?

The Galaxy M31 occupies a challenging position in the 2025 Australian smartphone market. Its strengths—particularly the 6,000mAh battery and 64MP main camera—remain genuinely competitive for users prioritising these features over processing speed or 5G connectivity. According to aggregated reviews from ProductReview.com.au (scoring 3.8/5 across 142 reviews), owners consistently praise battery life enabling two-day usage and the vibrant Super AMOLED display.

However, the device’s age introduces meaningful limitations. Performance on Android 12 shows visible lag on heavier applications, and the absence of 5G connectivity places it behind newer budget offerings. The lack of water resistance and the certainty of no further security updates create ongoing vulnerability concerns for security-conscious users.

Better Alternatives in the Current Market

For buyers committed to the Samsung ecosystem, the Galaxy M34 represents the most direct successor with its matching 6,000mAh battery while adding IP67 water resistance and extended software support through 2027. Those prioritising maximum value under AUD 250 will find the Galaxy M31 competitive on specs alone, but should carefully weigh the support gap against alternatives offering longer update commitments.

Samsung Galaxy M31 Reviews and Expert Assessments

Australian consumer reviews reveal consistent patterns in user satisfaction and complaints. The Galaxy M31 earned recognition as Canstar Blue’s Best Budget Battery Phone in 2020, with Reviews.org.au awarding four out of five stars and praising the device as a “battery king.” Contemporary 2025 reviews on ProductReview.com.au reflect the device’s evolved status.

“Still solid for basics in 2025, but battery at 85% health.” — ProductReview.com.au user, 2025 For those interested in the latest tech news Ireland, the Samsung Galaxy M31 continues to be a relevant device. Latest tech news Ireland

Whirlpool.net.au community discussions position the device as a capable “budget secondary phone” in 2025, with particular appreciation from 2020-era purchasers who secured strong value at original launch pricing. YouTube Australia reviewers like TechYesCity assign 7.5/10 for value when purchasing refurbished, recommending the device for students and light users prioritising battery endurance over gaming performance.

Common complaints across platforms include the absence of 5G connectivity, heating during extended gaming sessions, Samsung’s bloatware load, and increasing software lag as applications grow more demanding on the aging Exynos 9611 processor.

Where to Buy Galaxy M31: Final Recommendations

For Australian buyers proceeding with a Galaxy M31 purchase, prioritising warranty coverage and seller reputation delivers the best outcomes. eBay.com.au with sellers like Mobile Guru offers the strongest combination of selection, competitive pricing, and 12-month warranty protection. Kogan.com provides similar warranty coverage with the benefit of 2-year protection, though stock availability fluctuates more significantly.

Local pickup through Gumtree.com.au or Facebook Marketplace can achieve lower prices but removes consumer protection mechanisms. Buyers pursuing this route should inspect battery health using diagnostic applications before completing transactions, as lithium-ion batteries degradation becomes pronounced after four-plus years of use.

Battery replacement services through iFixit Australian partners cost approximately AUD 50 and may be worth considering for devices exhibiting reduced capacity. Samsung’s official IMEI verification tool on Samsung.com/au allows buyers to check for blacklisted devices before purchase.
