Firmware

Firmware is the low-level software that runs a handheld’s hardware, and manufacturers update it to fix bugs, improve battery behavior, patch stick calibration, and add features. Keeping it current is basic hygiene, and a maker’s firmware cadence is a real buying signal — a device that gets steady updates ages better than one abandoned at launch. We note support track record in reviews because a handheld’s long-term value depends as much on firmware upkeep as on its original specs.
