Frequently asked
When will the POCO M8 5G stop getting security updates?
POCO officially confirmed four OS upgrades and six years of security patches for the M8 5G, up from the old two-upgrade, three-year policy for the M series. From its January 2026 launch that means security support to around January 2032 and Android upgrades reaching roughly Android 19. For a phone this cheap, that is one of the longest support commitments in the industry and the headline reason to consider it.
Is the POCO M8 5G worth buying in 2026?
As a low-cost long-life phone it is outstanding value. At roughly $199 with six years of patches, it costs under $3 a month to keep secure, and the 120Hz AMOLED, light build and microSD slot are welcome extras.
