What New Spam Blocking on Android Actually Does
Android spam blocking now combines WhatsApp call identification, dialer spam filters, and AI call screening to detect risky calls, label suspicious numbers, and keep many scams away from users before they ever say hello. These features rely on caller ID databases, app permissions, and on‑device assistants to check unknown numbers, display warning tags, and, in some cases, even answer calls on your behalf to find out who is calling and why. Together, they aim to protect users from spam, telemarketing, and phone-based fraud by filtering or flagging questionable calls across both traditional mobile networks and internet calling apps. This guide explains how to enable WhatsApp call identification and ColorOS spam blocking on OPPO phones, and how to switch on AI call screening for scam call protection on Samsung Galaxy S26 devices, so you can reduce unwanted calls and stay safer.
Turn On WhatsApp Call Identification and ColorOS Spam Blocking
OPPO’s latest ColorOS update adds WhatsApp call identification and a dialer spam filter to strengthen scam call protection. According to The Tech Outlook, “the ColorOS May update brings Call Identification on WhatsApp, along with the OPPO Dialer Spam Blocking Function.” To enable WhatsApp call identification, open Phone Manager, tap Communication security, then Call identification. Switch on Call identification and toggle on support for WhatsApp. You can also go through Settings, then Security and privacy, then More security and privacy, and open App call identification. There, enable App call identification and select WhatsApp as a supported app. For accurate spam blocking on Android, grant Phone Manager access to Contacts, floating windows, and Notifications; without these, ColorOS treats all callers as unknown and may miss alerts. Once enabled, unknown WhatsApp callers are labeled with risk tags, helping you decide whether to answer or ignore.
Use OPPO Dialer’s Built-In Spam Blocking and Caller Identification
ColorOS strengthens spam blocking on Android through the native OPPO Dialer spam filter and caller identification service. In supported regions, the OPPO Dialer works with local service providers to recognize and label incoming numbers as spam, telemarketing, suspected scams, and more, so you know who might be calling before you pick up. To turn on Caller Identification, open Calls, tap the top-right menu (︙), go to Settings, then choose Caller Identification and enable it. The system will then provide online number information when unknown numbers ring. You can improve the dialer spam filter by flagging unwanted numbers yourself: open Calls, select a phone number, tap the ︙ menu, choose Flag, and apply the correct label. Over time, this shared data helps ColorOS spam blocking become more accurate, reducing nuisance calls and highlighting legitimate callers with clearer context on the incoming call screen.
Enable AI Call Screening on Samsung Galaxy S26
Samsung’s Galaxy S26 series introduces Call Screening, an AI-powered feature that answers unknown calls for you and filters potential scams without blocking them outright. When Call Screening is turned on, an AI voice assistant picks up unknown calls and asks the caller who they are and why they’re calling, while a live transcript appears in real time on your screen. You can then decide to answer yourself, end the call, or type text for the assistant to read out, which keeps your own voice out of the conversation and reduces the risk of voice cloning scams. While menus can vary, Call Screening settings typically sit in the Phone app under call settings or spam and call protection options. Once activated, Galaxy S26 users gain an extra layer of scam call protection that balances courtesy with security by letting callers explain themselves without granting full access to you.
Availability and How These Android Protections Work Together
These spam blocking Android tools rely on several layers working together: app call identification (like WhatsApp tagging unknown callers), carrier-linked caller ID databases inside the dialer spam filter, and on-device AI call screening that speaks to unknown callers for you. ColorOS users with the May update or later can access WhatsApp call identification and OPPO Dialer spam blocking, though features may appear only in certain regions and on supported devices. Samsung’s Call Screening is currently tied to the Galaxy S26 series and may expand through future software updates or appear under different names on other models. Even if your phone does not yet offer every feature described here, you can still benefit by enabling any available caller identification, spam filtering, or call protection options in your Phone and Security settings, creating a layered defense against spam and scam calls across your Android device.
