Samsung promises 4 years of security updates for Galaxy devices Samsung wasn’t always known to be a smartphone manufacturer who provided regular software updates for their devices. That has only changed in recent times, and now they are taking it a step further by promising 4 years of security updates to many Galaxy devices. Samsung has already promised 3 generations of OS upgrades for major Galaxy smartphones last year. Having 4 years of promised security updates (since its initial launch date) further increases the value proposition of purchasing a Samsung Galaxy device. List of eligible devices for 4 years of software updates: Galaxy Foldable devices: Fold, Fold 5G, Z Fold2, Z Fold2 5G, Z Flip, Z Flip 5G
