| Top Call Blocking Features to Look for in a New Smartphone |
Unwanted calls are one of the biggest frustrations smartphone users face today. From telemarketers and fraudsters to robocalls, these disturbances can disrupt your day and put your personal information at risk. Thankfully, most modern smartphones come with built-in call blocking features designed to give you better control over your privacy. If you’re planning to buy a new device, knowing the right features to look for can make a huge difference in your daily phone experience.
In this article, we’ll highlight the top call blocking features to look for in a new smartphone, how they work, and why they matter.
1. Spam Call Detection
One of the most important features to consider is automatic spam call detection. Modern smartphones use AI and large spam databases to identify potential scam or telemarketing numbers before you even pick up. The phone displays “Spam Risk” or “Potential Fraud,” giving you the option to reject or block the call immediately.
- Example: Google Pixel and Samsung Galaxy devices come with built-in spam detection powered by Google’s database.

2. Custom Block Lists
Your new smartphone should allow you to create a personal block list where you can add numbers you don’t want to hear from again. This feature is helpful for blocking persistent telemarketers, ex-contacts, or repeat robocalls.
- Most Android devices have a “Block Number” option in the call log or contacts app.
- iPhones also allow you to block any number directly from the Phone app.
3. Unknown Number Blocking
Sometimes spam calls come from numbers not saved in your contacts. A reliable smartphone should allow you to block all unknown callers automatically. This ensures that only numbers you’ve saved can reach you, while all others are silenced or sent to voicemail.
- iPhone has a “Silence Unknown Callers” feature under Settings → Phone.
- Many Android devices have a similar option in the Phone app settings.
4. Do Not Disturb (DND) with Caller Exceptions
A good smartphone should have a Do Not Disturb mode that lets you silence all calls except from selected contacts, such as family members or work colleagues. This prevents late-night spam calls while ensuring important people can still reach you.
- Both Android and iOS allow caller exceptions in DND mode.

5. Third-Party Call Blocking App Support
While built-in tools are great, sometimes you may want extra security from third-party apps. Your smartphone should support popular apps like:
These apps provide advanced features like spam databases, community-based call reporting, and real-time fraud alerts.
6. One-Tap Reporting
Modern smartphones should let you report spam calls directly from your call log. This not only helps you but also updates the global spam database to protect other users. Look for a device with easy spam reporting integrated into its Phone app.
7. Carrier-Level Call Blocking Support
Some smartphones work closely with mobile carriers to provide network-level spam protection. This means suspicious calls can be blocked before they even reach your device.
- AT&T’s Call Protect, T-Mobile’s Scam Shield, and Verizon’s Call Filter are examples.
- In Nigeria, MTN and Airtel also provide call barring services that integrate with your phone.
When buying a new smartphone, don’t just focus on the camera, storage, or speed — make sure it comes with robust call blocking features. Look for spam detection, custom block lists, unknown number blocking, and support for third-party apps. With these features, you’ll enjoy peace of mind, fewer distractions, and better protection against fraud.
If you’re unsure which phone to buy, research the call blocking features first to ensure you’re getting the best security along with performance.
Always keep your phone software updated, as manufacturers regularly improve spam protection with new security patches.
