Still: Call Blocker

Keep your default phone app. Still adds an extra layer of call-blocking controls, so you can decide which incoming calls reach you. Use contacts-only filtering, number-prefix rules and quick pause controls alongside your usual dialer. A little more quiet, with simple rules that run on your phone. CONTACTS ONLY Reject visible caller numbers that are not saved in your contacts. Saved callers stay allowed by default. BLOCK NUMBER PREFIXES Block a number series using a prefix, such as +1202 or +9179. Add, edit and switch individual rules on or off. Use the country code when you want an international match. Prefixes match the number supplied by Android; local and international formats are not guessed. SEE WHAT STILL BLOCKED View the latest 200 calls rejected by Still, with the number, time and blocking reason. This is Still's own blocked-call history, not a copy of your system call log. QUICK CONTROLS Pause, pause for 15 minutes, or resume from the app, optional notification controls, or a home-screen widget. The larger widget also offers Contacts only and Prefix mode switches. Turning Contacts only off switches Prefix mode on. SHARE YOUR PREFIX RULES Export a prefix-only JSON file through Android's share sheet. Import from the file picker or open a JSON attachment with Still. Review the list before saving. Duplicates are skipped and existing rule switches are preserved. New entries start off unless you choose Enable all new prefixes in the preview. PRIVATE BY DESIGN Still has no ads, accounts, analytics or Internet permission. Contacts and call decisions are processed locally. Exports contain prefixes only, not contacts or blocked-call history. Sharing happens only when you choose to export a file and select another app. KEEP YOUR USUAL PHONE APP Still works alongside your existing dialer and Contacts app. Select Still as Android's call-screening app to add its blocking controls; you do not need to replace your default phone app. Only one call-screening app can be active at a time. PERMISSIONS WITH A PURPOSE Optional Contacts access supports real contact checks in the number tester and applying prefix rules to saved contacts. Optional notification permission enables the control card. The widget requires neither notification nor storage permission. BEFORE YOU RELY ON IT Still requires Android 10 or later and a device that supports Android call screening. Setup and behavior can vary by device and carrier. Hidden or private caller IDs are not available for Still to evaluate. Still does not identify spam from a cloud database, block SMS or messaging-app calls, or control carrier voicemail. A rule can block a legitimate unsaved caller, so choose prefixes carefully. If a contact lookup fails or times out, the call is allowed. Support: [email protected]
