What Is com.samsung.android.dialer? Samsung Phone App (2022–2026)

Seeing com.samsung.android.dialer in App info, battery stats, or a permissions list on a Galaxy phone? That package is Samsung’s Phone (Dialer) app — the system interface for the dial pad, call history, favorites, and related One UI calling features. It is not a random sideloaded app and not malware by default.

This page explains what the Samsung Dialer does, how it relates to InCallUI and telephony UI packages, what to do about crashes or a blank pad, and which “optimizer” tips will break calling.

What the Samsung Dialer does

During everyday use, Android separates “who you call” from “what you see while the call is active.” On many Samsung builds:

• com.samsung.android.dialer (Phone) lets you dial numbers, search contacts, and open history
• Telephony / modem layers set up the call
• InCallUI draws controls once the call connects

That is why you may see com.samsung.android.dialer in App info even if you mostly use the green Phone icon and never typed the package name.

You will typically notice it when:

• Checking which app owns the Phone icon
• Android asks for Phone or Contacts permissions after an update
• The dial pad is blank, laggy, or crashes on open
• A forum post lists the package next to “suspicious system app”

Quiet use outside of opening Phone or placing calls is normal.

Dialer vs InCallUI vs telephonyui

People often confuse three legitimate Samsung packages:

Package	Typical job	Safe default
com.samsung.android.dialer	Dial pad, history, favorites	Leave enabled
InCallUI	On-call controls and call screen	Leave enabled
Telephony UI helpers	Extra call-related UI services	Leave enabled

For the in-call screen specifically, see com.samsung.android.incallui. For related telephony UI naming, see com.samsung.android.app.telephonyui. Different builds label screens slightly differently, but the rule is the same: system call packages are not “unknown APKs.”

If you installed a “fancy dialer” or call-recorder APK that demands Accessibility and overlay permission, that third-party app is a better suspect for weird Phone behavior than Samsung Dialer itself.

Is it malware?

Check	Good sign	Bad sign
Package name	Exact com.samsung.android.dialer	Typos, extra suffixes, lookalike names
App label	Phone / Dialer	Random “Cleaner,” “Booster,” or blank
Install source	Preinstalled / system / Galaxy store update	Sideloaded unknown APK
Uninstall	Cannot remove like a normal app	“Uninstall Samsung virus” ads
Behavior	Dial pad and call history	Overlay scams, premium-rate spam dialers

If App info shows Phone and the package is system-backed, treat scare posts with skepticism.

Scareware and fake “dialer” alerts

Pop-ups that say “com.samsung.android.dialer is infected” are usually trying to sell a cleaner or push a fake support call. They borrow a real package name so the warning looks technical.

Do not:

• Call numbers from full-screen virus ads
• Install “Phone repair” APKs from random sites
• Grant Accessibility to tools that promise to delete the Dialer
• Freeze Phone with “Game Booster” or package disablers for a battery myth

If the whole phone is frozen and you cannot open Phone at all, start with a clean force restart before any third-party optimizer.

Permissions — why so many?

Phone/Dialer needs elevated capabilities because it places calls and reads communication data:

• Phone — place and manage calls
• Contacts — show names and favorites
• Call logs — history and recents
• Microphone (when relevant) — calls and related features
• Notifications — missed-call alerts
• Nearby devices / Bluetooth (varies) — headset routing entry points

Revoking core Phone or Contacts permissions does not make you “more secure” if you still want a working dialer. It usually creates empty history, failed searches, and crash loops. Treat Dialer like other system phone components: leave defaults unless a specific feature toggle is documented by Samsung.

What you should (and should not) do

Do

1. Keep Phone and system updates current
2. Set Samsung Phone as the default phone app unless you intentionally use another dialer
3. Clear cache when the pad is blank or Phone force-closes
4. Test calling in Safe mode if a third-party dialer was installed recently
5. Watch battery for a day after a major One UI update before chasing Dialer alone

Do not

• Disable com.samsung.android.dialer to “save RAM”
• Sideload an old Phone APK from a random mirror
• Grant Accessibility to cleaners that blame Dialer for drain
• Factory reset as step one for a one-day crash

Blank dial pad or Phone crashing — calm workflow

1. Force-restart the phone so Phone and related services reload
2. Open Settings → Apps → Phone (com.samsung.android.dialer) → Clear cache
3. Confirm Contacts and Phone permissions are allowed
4. Boot into Safe mode and open Dialer again
5. If only third-party dialers work in Safe mode, uninstall the conflicting app
6. If stock Phone still crashes with no third-party apps, note the exact One UI / Android version for support

If audio connects but the on-call screen is blank, the problem may be InCallUI rather than Dialer — use the InCallUI guide linked above after you can place the call from Phone.

Battery — when Dialer is (and is not) the culprit

Opening Phone, syncing call-related features, or a stuck crash-restart loop can show Dialer in battery charts. That does not mean the package is malware.

If Battery blames Phone while you barely dial:

1. Check for crash loops (Phone opening itself repeatedly)
2. Clear cache and reboot
3. Review recently installed overlay or caller-ID apps
4. Compare with broader One UI drain patterns in Samsung battery drain on One UI

Persistent drain with a quiet call log usually points elsewhere: social apps, always-on GPS, bad launchers, or failing charge hardware.

When to clear cache (and when to clear data)

Safe order:

1. Force-restart once
2. Clear cache for Phone / com.samsung.android.dialer
3. Retest dial pad and one outbound call
4. Clear data only if Phone remains unusable — you may need to re-allow permissions and redo dialer settings

Never “uninstall updates” for Phone because a short video promised a secret speed boost. If soft fixes fail and calling is business-critical, gather model, software version, and whether Safe mode works before a shop visit.

Bottom line

com.samsung.android.dialer is Samsung’s Phone/Dialer system app. Leave it enabled, keep it updated, clear cache when the pad breaks, test Safe mode before sideload “fixes,” and ignore scareware that treats a normal Galaxy package name as an infection.
