How to use this directory

Start with the marketed name, then confirm the model number and region on the device page. “Ending soon” means the recorded security-support date is within twelve months; “support ended” does not mean the hardware immediately stops working, but the cited commitment has passed.

Phone manufacturers describe support in different ways. A model-specific cutoff, a duration calculated from first sale and an operating-system eligibility list are different facts. Open the exact record before applying a date to a carrier or regional variant.
