How to Put a Contact on DND (Do Not Disturb) on iPhone and Android

Silencing notifications from a specific person — without blocking them or muting your entire phone — is one of those features that sounds simple but works differently depending on your device, OS version, and what you actually want to achieve. Here's how Do Not Disturb (DND) for individual contacts works, and what affects how well it works for your situation.

What "DND for a Contact" Actually Means

When most people ask how to put a contact on DND, they're asking one of two different things:

  • Silence a specific person so their calls and messages don't make noise
  • Block all interruptions from everyone except certain people (the opposite approach)

These are meaningfully different features, and platforms handle them differently. Understanding which one you need is the first step.

How to Put a Contact on DND on iPhone 📵

On iOS, Apple doesn't have a single button labeled "DND for this contact." Instead, you work through a combination of Focus modes and notification settings.

Option 1: Mute Notifications from a Specific Contact

  1. Open the Messages app and tap the conversation with that contact
  2. Tap the contact's name at the top
  3. Select Info
  4. Toggle on Hide Alerts

This silences iMessage and SMS notifications from that person. Their messages still arrive — you just won't hear or see alerts for them.

For calls, the process is different. There's no native per-contact call silencing on iOS outside of blocking or using Focus filters.

Option 2: Use Focus Mode to Allow Only Certain People

Focus (introduced in iOS 15) lets you build a DND-style mode where only approved contacts can reach you:

  1. Go to Settings → Focus
  2. Choose or create a Focus (e.g., Do Not Disturb, Personal, Work)
  3. Under Allowed Notifications, tap People
  4. Add the contacts you want to allow through

This flips the logic — instead of silencing one person, you silence everyone except a list. That's a powerful distinction depending on your use case.

How to Put a Contact on DND on Android

Android's approach varies more significantly across manufacturers and OS versions, but the core tools are consistent.

Option 1: Mute a Conversation in Messages

In Google Messages (the default on many Android devices):

  1. Open the conversation
  2. Tap the three-dot menu (top right)
  3. Select Details or People & options
  4. Toggle on Notifications to off/mute

This suppresses message alerts from that contact without affecting anything else.

Option 2: Use DND with Exceptions via Priority Mode

On stock Android (and most manufacturer variants):

  1. Go to Settings → Sound → Do Not Disturb
  2. Tap People or Exceptions
  3. Set which contacts can break through (calls, messages, or both)
  4. Enable DND when needed

Like iOS Focus, this is an allowlist approach — you define who can reach you, not just who can't.

Option 3: Samsung and Other OEM Variations 🔔

Samsung One UI, MIUI, and other Android skins often add extra layers. For example, Samsung has Modes and Routines, which can automate DND based on time, location, or activity — and let you customize contact exceptions within those modes.

If your device runs a manufacturer skin, the exact menu names and paths may differ from stock Android, so it's worth checking your specific settings under Sound, Notifications, or Digital Wellbeing.

Key Variables That Affect How This Works

VariableWhy It Matters
iOS vs AndroidFundamentally different permission structures for per-contact silencing
OS versionFocus didn't exist before iOS 15; Android DND options expanded in Android 9+
App usedThird-party apps (WhatsApp, Telegram) manage their own notification settings independently
Call vs messageMost platforms handle these separately — silencing messages doesn't silence calls
Manufacturer skinSamsung, Xiaomi, and others modify stock Android DND options significantly

Third-Party Messaging Apps Are a Separate Layer

If you're using WhatsApp, Telegram, Signal, or Instagram DMs, your phone's native DND or mute settings may not apply. Each app has its own mute/silence feature:

  • WhatsApp: Open chat → tap contact name → Mute Notifications → choose duration
  • Telegram: Open chat → tap contact name → Mute
  • Signal: Open chat → tap name → Mute

Muting within the app overrides system-level notification behavior for that app's messages. This is an important distinction — silencing someone in iOS Messages or Android Messages won't silence them in WhatsApp.

The Spectrum of Use Cases

How this feature should be configured varies widely:

  • Light touch: You just want one chatty contact to stop pinging you during meetings — a simple mute in Messages is enough
  • Focused work mode: You want to silence almost everyone except key contacts — Focus/DND with an allowlist fits better
  • Cross-platform household: You communicate across multiple apps, which means you may need to configure mute in each app separately
  • Automated scheduling: You want DND to activate on a schedule automatically — this requires Automations (iOS) or Routines (Android) on top of the basic settings

The right configuration depends on which apps you actually use to communicate with that contact, whether you're trying to silence one person or protect your focus from the world, and how much control your specific device and OS version gives you. Those factors together — not the feature in isolation — determine what will actually work for you.
