Phones with the longest software support

277 of the 322 phones we list have a support reference date still in the future. We sort that date latest first, using a sourced manufacturer deadline or, where later, a conservative EU floor calculated from EPREL first-sale data and declared update years. Each row identifies the date type. An EU floor is a planning reference, not a confirmed date when updates stop; it can understate the eventual support period. Phones without either reference are left out. Check the model page and current manufacturer policy before buying.
