How to Block a Number on an LG Phone

Unwanted calls and texts are frustrating, and LG Android phones give you several ways to deal with them. Whether you're dealing with spam robocalls, persistent telemarketers, or someone you simply don't want to hear from, the blocking tools built into LG devices are straightforward — once you know where to find them.

Why Blocking Methods Vary Across LG Phones

LG produced phones across a wide range of Android versions and custom UI skins — from older LG UX versions to near-stock Android on later models. The exact menu paths can differ depending on your phone model (LG G series, V series, Stylo, K series, Velvet, etc.) and the Android version installed.

That said, the core blocking methods are consistent across most LG devices, and the logic is the same even when specific menu labels shift slightly.

Method 1: Block Directly from the Phone App 📞

This is the fastest route for blocking a number that has already called you.

  1. Open the Phone app
  2. Go to your Recent calls or Call log
  3. Tap the number or contact you want to block
  4. Tap the three-dot menu (⋮) in the top-right corner
  5. Select Block number or Add to reject list (label varies by LG model)
  6. Confirm the block

On some LG models running older versions of LG UX, the option may appear as "Add to reject list" rather than "Block number." Both do the same thing.

Method 2: Block from a Text Message (Messages App)

If the unwanted contact is reaching you via SMS:

  1. Open the Messages app
  2. Open the conversation from the number you want to block
  3. Tap the three-dot menu in the top-right
  4. Select Block number or Block contact
  5. Confirm when prompted

This blocks both calls and texts from that number in most cases, though behavior can depend on the messaging app you're using (stock LG Messages vs. Google Messages vs. a third-party app).

Method 3: Block from Your Contacts List

If the number is saved as a contact:

  1. Open the Contacts app
  2. Find and open the contact
  3. Tap the three-dot menu
  4. Select Block contact or Add to reject list

This is useful when you want to block someone without digging through your call history.

Method 4: Using the Call Settings Reject List

LG phones typically include a dedicated reject list in call settings, which gives you more control:

  1. Open the Phone app
  2. Tap the three-dot menu or the Settings gear icon
  3. Go to Call settingsReject calls or Call reject
  4. Tap Reject list or Block list
  5. Use the + button to manually add a number

This method is particularly useful for adding numbers you haven't received a call from yet — for example, a number you found suspicious or received via text.

What Happens When You Block a Number on LG?

Understanding what blocking actually does helps set expectations:

What Gets BlockedWhat Happens to the Caller
Incoming callsCalls go directly to voicemail or are silently rejected
SMS/MMS messagesMessages are not delivered to your inbox
NotificationsNo alerts or sounds for blocked contacts
VoicemailMay still be left, depending on carrier settings

Important: Blocking on your device is handled at the phone level, not the carrier level. This means a blocked caller may still be able to leave a voicemail on some networks. Carrier-level call blocking (offered by most major carriers as a separate feature) works differently and can complement device-level blocking.

Google Phone App vs. LG's Stock Dialer

Some LG phones — particularly newer models or those updated to Android 10+ — use the Google Phone app as the default dialer rather than LG's own app. If your phone app looks different from the descriptions above:

  • Open the Phone app → Recent tab
  • Long-press the number
  • Select Block/report spam

Google's Phone app also offers spam detection features that can automatically flag or filter likely spam calls before they reach you, which is a meaningful advantage over the basic LG reject list.

Third-Party Blocking Apps

If the built-in tools aren't meeting your needs — for example, if you're dealing with high volumes of spoofed numbers or robocalls — third-party call-blocking apps are available through the Google Play Store. These apps typically maintain large databases of known spam numbers and can block them proactively.

The tradeoff is that these apps usually require permissions to access your contacts and call log, which is worth considering from a privacy standpoint.

Variables That Affect Your Experience 🔧

Several factors determine which method works best for your situation:

  • LG model and UI version — menu paths differ between LG UX 8, 9, and near-stock Android models
  • Default dialer — whether you're using LG's app, Google Phone, or a third-party dialer changes the steps
  • Carrier settings — some carriers override or supplement device-level blocking
  • Android version — older Android versions may have fewer built-in blocking options
  • Type of nuisance calls — a single known number is handled differently than mass spoofed robocalls

The built-in tools on most LG phones handle everyday blocking situations well. But whether those tools are sufficient — or whether a carrier-based solution or third-party app would serve you better — depends on the volume and type of calls you're dealing with, and how your specific phone's software is configured.
