Phone spam is still a daily headache in 2025. Android users now have two heavyweight options to fight back: Google’s Pixel Call Screen and Samsung’s new automatic call screening prepared for One UI 8.5. Both promise fewer interruptions, safer call handling, and smarter triage—yet they work differently and carry distinct privacy and availability trade‑offs. This head‑to‑head comparison explains how each system screens calls, what’s on‑device vs cloud, which languages and regions are supported, how the transcripts look, and which one you should choose for your phone and workflow.
Two different paths to fewer spam interruptions—choose based on privacy, features, and availability.
Quick verdict
If you own a recent Pixel, Pixel Call Screen remains the most reliable and privacy‑friendly choice thanks to on‑device smarts and polished transcripts. If you’re in Samsung’s Galaxy ecosystem, One UI 8.5’s Automatic Call Screening looks promising—especially combined with Bixby Text Call—but at launch it may be limited by device, region, or language while Samsung finishes rollout. For renters and multi‑line users who rely on voice assistants and flexible options, either will beat third‑party spam blockers, but Pixel’s consistency gives it the edge today.

How Pixel Call Screen works in 2025
Pixel Call Screen routes unknown or suspicious calls to a Google Assistant responder that speaks to the caller and displays a live transcript on your phone. You can choose prompts like “Who’s calling?” or “Why are you calling?” or immediately decline if it’s clearly spam. On newer Pixels, the voice/ASR runs largely on‑device for speed and privacy. Options like Auto‑Screen can silently handle likely spam without bothering you.
On‑device by default: Transcription and prompts run locally on supported models, speeding up responses and reducing data exposure.
Better triage: Quick replies and a natural flow help legit callers reach you, while bots usually fail the screening.
Companion tools:Hold for Me and Direct My Call improve business IVR navigation—handy if you return the call.
How Samsung’s One UI 8.5 call screening is shaping up
Samsung already offers Bixby Text Call, which lets you answer by text while Bixby voices your responses. The new piece—automatic call screening—is preparing to handle spam and unknown calls without you picking up, similar to Pixel’s approach. According to firmware teardowns, Samsung is adding code paths for auto screening and categorization. Final features, regions, and device eligibility will depend on Samsung’s official rollout and carrier cooperation.
Important: At the time of writing, the automatic screening feature is in development and may change before broad release. Expect staged availability by region, language, and device tier.
One UI 8.5 pairs Bixby Text Call with new auto screening primitives—final UI/regions subject to change.
Head‑to‑head: accuracy, speed, and reliability
Accuracy and false positives
Pixel’s long track record and Google’s massive spam signals give it consistently strong detection with few false positives, especially in regions where it’s officially supported. Samsung’s accuracy will likely start strong for obvious spam and improve over time as models and heuristics learn. Early months may see more variance by carrier and country until coverage stabilizes.
Speed and responsiveness
Pixel’s on‑device transcription delivers near‑instant caller prompts and readable text. Samsung’s approach should be comparable, though early releases may lean more on network lookups depending on your region and carrier integration.
Handling edge cases
Legit but unknown numbers: Pixel’s clear prompts and transcript make it easy to identify delivery drivers, clinics, or schools. Samsung’s Bixby Text Call hand‑off could be excellent for back‑and‑forth, once screening triggers reliably.
International/spoofed calls: Both rely on a mix of reputation and conversation analysis. Expect some manual overrides for niche cases.
Assistant answers first, you read the transcript, then decide: accept, decline, or ask more.
Privacy and data handling
Privacy matters as much as blocking spam. Here’s the practical breakdown:
Pixel Call Screen: Uses on‑device processing on supported phones. Transcripts live on your device unless you share them. You control auto‑screen rules and exceptions per contact.
Samsung One UI 8.5: Expected to favor local‑first handling with system services and Bixby Text Call. Exact retention and sharing controls will be detailed at launch; review Samsung’s call and privacy settings once available in your region.
Best practice: regularly audit your call‑blocking rules, check exception lists for work and family numbers, and review your phone app’s spam sources and permissions.
Setup and daily use
Pixel
Open Phone → Settings → Spam and Call Screen.
Enable See caller and spam ID and Call Screen.
Set Auto‑Screen behavior for unknown numbers and suspected spam.
Optionally enable Hold for Me and Direct My Call where available.
Samsung (One UI 8.5)
Open Phone → Settings → Caller ID and spam protection / Bixby Text Call.
Enable spam protection and configure Bixby Text Call for manual screening.
Once automatic call screening is available, toggle categories (spam/unknown) and exceptions.
Test with a trusted unknown number to calibrate behavior.
Languages and regional availability
Pixel’s strongest language and feature coverage remains in English‑first regions, with ongoing expansion. Samsung’s coverage will likely follow its typical One UI rollout: flagship models first, then mid‑range, with language packs staged by market. Always check your device’s release notes and region settings.
Cost and requirements
Pixel Call Screen: Included with no subscription. Best experience on newer Pixels (Pixel 6+), with partial support on some earlier models in select regions.
Samsung Automatic Call Screening: Included with One UI 8.5; availability depends on device, carrier, and market.
For Android call screening in 2025, Pixel Call Screen still sets the bar for speed, clarity, and privacy—particularly on recent Pixel hardware. Samsung’s One UI 8.5 Automatic Call Screening has strong potential—especially for users who already rely on Bixby Text Call—but it needs a full public rollout to match Pixel’s proven consistency. If you want fewer interruptions today and you can choose your device, Pixel wins. If you’re all‑in on Galaxy, keep spam protection enabled now and turn on auto screening the moment One UI 8.5 reaches your phone.
FAQs
Is Samsung’s automatic call screening available on my Galaxy yet?
Rollout is tied to One UI 8.5 and may vary by model, region, and carrier. Check your Software Update and Phone app settings periodically.
Does Pixel Call Screen work offline?
On supported Pixels, screening and transcription run largely on‑device for speed and privacy. Some features and language packs may still require updates or network access.
Can these systems block spoofed numbers?
They can flag suspicious patterns and prompt callers, but no solution catches 100% of spoofing. Use screening plus carrier filters and blocklists for best results.
Will screening miss important calls?
It can happen. Reduce risk by whitelisting key contacts, enabling repeat‑caller exceptions, and quickly promoting legitimate numbers to contacts.
Do I need a subscription?
No. Pixel Call Screen and Samsung’s call screening features are included with the phone software.
How do transcripts get stored?
On Pixels, transcripts live on your device unless you choose to share or back them up. Samsung’s storage and retention details will be clarified at launch.
Which is better for business lines?
Today, Pixel’s mature flow and reliable transcripts make it easier to recommend for business users. Re‑evaluate Samsung after One UI 8.5 reaches your device.
