There is an ongoing debate: Should manufacturers be legally required to release signed, compatible drivers for obsolete hardware? A4Tech ceased support in 2014, but users continue to rely on these devices. This paper supports the Driver Longevity Act proposal (EU Right to Repair 2025 draft) that would mandate providing driver source code after product EOL.
A4Tech rarely pushes automatic updates. Manually check the official site every 6 months. To update, simply uninstall the old version first, then install the newer .exe package.
You can set up to 4 DPI profiles. Typical settings:
Use the DPI button on the mouse (usually just below the scroll wheel) to cycle through them.
