DevLifeCheck: a support calendar for the devices you depend on

Field notes

Device records combine regional scope, manufacturer-policy interpretation, firmware details, recall coverage, and evidence grades rather than presenting a single unsupported end date. The homepage lists 308 phones and 17 tablets, and its examples include a Pixel 8 with North America mmWave coverage and an October 2030 security-support date. The site also states that OS-upgrade promises are not converted into security dates, keeping those claims separate from security support.
