How long do Asus phones get updates?
2 OS upgrades + up to 5 years of security updates (ROG Phone 9 Pro)Official
Asus pairs a short OS-upgrade promise with a longer security window. Its ROG Phone 8 Pro and 9 Pro get about two Android upgrades but up to five years of security patches; the Zenfone 11 Ultra gets two upgrades and four years. That trails the seven-year mainstream leaders on major OS versions, even though security support runs fairly long.
