Nothing Phone (3a) Lite Update FAQ
How do I install a Nothing OS update?
Open Settings, go to System, then System update and tap Check for update. Keep the phone on Wi-Fi with at least 30% battery. Rollouts are staged, so the update can reach your device days after it appears here.
Why has my phone not received the update yet?
Nothing releases updates in phases by region and carrier. A build listed on this page means it has been published, not that it is live for every user. Waiting a few days is normal.
Is it safe to update to a new Nothing OS version?
Yes, official OTA updates are safe, but back up photos, contacts and call logs first, especially before a major upgrade. Your phone may feel warm and use more power right after installing.
What do the build numbers mean?
A build such as B4.1-260415-1709 reads as branch B4.1, build date 26-04-15 (15 April 2026) and build time 17:09. Builds starting with V belong to Nothing OS 3.x, B to 4.x and C to 5.x.
