Nothing OS 5.0 Is Rolling Out to Phone 3a and 4a: What’s New and How to Get It

If you own a Nothing Phone (3a) or (4a), Nothing OS 5.0 is now rolling out to you. It brings Android 17 and a long list of Nothing-specific changes, including a new Glyph app and system-wide theming.

Updates arrive in batches, so don’t panic if your phone shows nothing yet. Here’s what you get and how to check.

The short version, in five lines:

• Phones: Nothing Phone (3a), (3a) Pro, (4a) and (4a) Pro.
• Software: Nothing OS 5.0, built on Android 17.
• Rollout: started October 30, 2026, globally and in batches.
• Phone (3) owners: you got Android 17 a few weeks earlier.
• Where to check: Settings > System > System updates.

That’s all you need if you’re in a hurry. The rest explains what actually changes on your phone.

What’s new in Nothing OS 5.0 on the Phone 3a and 4a series

According to 9to5Google, this is the full Android 17 update for the 3a and 4a families. It’s more than a version bump, because Nothing packs in a lot of its own work.

Here are the main additions:

• A dedicated Glyph app that takes over the Glyph Interface features.
• Split mode for Quick Settings.
• Bulk icon management for your home screen.
• Three new widgets: Collector, Away Time and Glyph Timer.
• A Translucent theme you can apply system-wide.
• More lock screen customization options.

Most of these target everyday tidiness. Moving icons in bulk alone will save anyone with a messy home screen a few minutes.

A new Glyph app and a calmer home screen

The Glyph app is the biggest change for Nothing fans. Instead of burying light controls in system menus, they now live in their own app with a revised interface.

The Glyph Timer widget fits that idea. It puts a timer on your home screen that ties into the Glyph lighting.

The Translucent theme is the one you’ll notice first. It applies across the whole system, so your phone looks consistent instead of half-themed.

Camera upgrades and a new AI privacy light

The camera app gets a refreshed interface. It also adds Dual-view Video, which records with the front and rear cameras at the same time.

The more interesting addition is a yellow AI Processing indicator. It appears when your phone is processing potentially sensitive data with AI.

That’s a small but useful signal. You can see at a glance when AI features are touching something private.

How to get the Nothing OS 5.0 update now

Open Settings, scroll to System, tap System updates, then tap Check for updates. If nothing shows, wait a few days and try again, since the rollout is staged.

The changelogs are labeled C50. Here are the build codes listed for each model, so you can confirm you got the right one:

Before you install, back up your photos and chats. It’s a big update, and a backup costs you five minutes.

Android 17 is still rare in the wild. As we covered in our post on Android 17 sitting on just 1% of devices, most phones are still waiting. If you’re on a Nothing 3a or 4a, you’re ahead of the pack.

What to check right after you install Nothing OS 5.0

Give the phone a few minutes after the first boot. Apps often reoptimize in the background, and judging speed too early is unfair.

Then run through a short checklist:

• Open the new Glyph app and confirm your lighting settings carried over.
• Try Quick Settings split mode and keep it only if you like it.
• Test Dual-view Video once, since it records from both cameras and uses more storage.
• Add the Away Time or Collector widget and see whether it earns its space.

If something looks off, a restart usually fixes odd animations. Persistent bugs are worth reporting to Nothing through its feedback channels.

Frequently Asked Questions

Which phones get Nothing OS 5.0 now?

The Nothing Phone (3a), (3a) Pro, (4a) and (4a) Pro. The Nothing Phone (3) started receiving stable Android 17 a few weeks earlier.

Is Nothing OS 5.0 the same as Android 17?

It’s Nothing’s version of Android 17. You get the Android 17 base plus Nothing’s own features, like the Glyph app and the Translucent theme.

Why don’t I see the update yet?

The rollout is going out in batches. Check again over the next few days under Settings > System > System updates.

What is the yellow AI Processing indicator?

Our take: install it, but back up first

If you have a 3a or 4a, take the update as soon as it appears. The Glyph app, bulk icon tools and the AI privacy light are real everyday upgrades, not filler. Just back up first, and give it a day or two before you judge battery life.
