How do I select a call rule?
Open RULES and double-tap the rule you want. The selected rule controls calls when Normal Protection is active. A single tap only expands or collapses its options.
How do I enable a filter?
In RULES, go to FILTERS and double-tap the filter. A single tap opens or closes its settings. The summary shows selected filters, but the active rule determines which filters can actually block a call.
How do I enable Travel Mode?
In RULES, double-tap Travel Mode. Waiting means the automation is on, but the configured speed or Bluetooth connection has not activated the mode yet. A single tap opens the settings.
How do I share my location?
In MAP, double-tap Share Location. Grant precise location and notification permissions if requested. You also need a linked Google Account, a verified number and internet access. Without an authorized contact, the feature stays on Waiting and does not publish your location.
How do I create a schedule?
Open SCHEDULE and tap Add. Choose the days and times, double-tap the desired rule and filters, then tap Save. If it overlaps another active schedule, resolve the conflict before saving.
Why was a call blocked or allowed?
Open LOGS and tap the call once. Its details show the classification, risk, reason, criterion, active rule and SIM when that information is available.
How do I back up my settings?
In SETTINGS → SETTINGS, tap Backup once, then Confirm. A linked Google Account and internet access are required. Wait for confirmation that the backup is complete.
A new backup replaces the last settings backup saved to the same Google Account; it does not create a version history. Creating a backup does not restore data.
How can I get started without blocking my family?
Choose who should be able to call. If you need calls from couriers, doctors or other unsaved numbers, Unknown Callers allows those calls subject to filters. Contacts allows Contacts, Favorites and the Whitelist. Double-tap your rule in RULES and check the header. Authorize call identification/blocking when Android asks. Arrange a test call and check LOGS. Avoid Block All: it also blocks family members and whitelisted numbers.
Does the app block WhatsApp calls or SMS messages?
Call Blocker X handles telephone calls delivered by Android to its call identification and screening service. It is not an SMS blocker and does not provide its own control over WhatsApp or other app calls. Use those apps’ own controls. The SMS used to verify your number is not a message filter.
Do I always need internet to block calls?
Saved rules and lists participate in local blocking decisions, and the app has cached Anti-Spam information. Without internet, community reputation data may be out of date. AI support, online backup, invitations, location sharing and route uploads require a connection. Android must still authorize call blocking. Check an arranged test call in LOGS.
Must I keep the app open? Why are there ongoing notifications?
You do not need to keep the app on screen for call protection. Travel Mode, location sharing and route recording are separate features that can run while the app is minimized, depending on permissions and settings. A notification indicates activity but does not guarantee that all data is up to date. Stop a feature using its control in the app. Do not force stop, clear data or uninstall as the first troubleshooting step. Android battery restrictions may affect background operation.
Is location required for everything? How can I reduce battery use?
Location is needed for Map, Travel Mode, Share Location and My Route according to the feature you enable. It is not the condition used to select numbers in a normal call rule. Turn off location features you do not use and disable Keep screen on in Map if unnecessary. SETTINGS → Battery: Unrestricted opens Android settings with one tap to help background operation; it does not promise lower battery use. Names and effects vary by device.
How do I keep my settings when changing phones or numbers?
When changing only your phone, open SETTINGS → SETTINGS, tap Backup once, confirm and wait for completion, using your Google Account and an internet connection. On the new phone, link the same account, tap Restore once and confirm. Check the result and grant Android permissions again. Backups do not include call history or credentials; Android contacts are separate from the app’s lists.
Changing the linked number requires verifying a new number you control while keeping the same Google Account. Your account, private data, rules, settings and app lock are preserved. Previous map invitations and location-sharing links are ended: they do not move to the new number and are not restored if you switch back to the old number. To share again, send or request new invitations, make sure they are accepted and enable sharing again. This changes your app profile, not the phone number on your Google Account.
Do I need to pay? How do PRO and ads work?
The app is Free • With ads. Plan, under SETTINGS → ACCOUNT AND PLAN, is an information card and does not open a window when tapped. PRO is not available; subscriptions, in-app purchases and video rewards are not active.
Banners may appear in LOGS, MAP, SCHEDULE and SETTINGS, subject to consent where required and availability; RULES has no banner. A full-screen ad may appear after a user-initiated tab change, at least 4 hours apart, but not at startup, during calls or in the background. Test Ad identifies a test advertisement. Report unexpected behavior with the time and app version; do not click ads to test or support the app.
How do I update without losing settings? What about the splash screen?
In SETTINGS → INFORMATION, tap the version number once. The app checks Google Play and opens the update window if a release is available for your account. Checking does not install anything automatically. You can also use Update in the Play Store. Do not uninstall to update: a normal update preserves data, while uninstalling may delete it. Availability depends on the release offered to your account and, for testing, your enrollment in the program. The app also has update alerts, according to your settings. The custom splash screen appears at the start of a new session; Android may show its own launch transition.
How do I use Usage Tips to understand a control?
Usage Tips are always available; there is no need to enable them in SETTINGS. Tap the assistant icon in the header and choose Usage Tips or Contact support. You can also press and hold the icon, drag it to an item and release to see its explanation. If the guidance does not match the screen, tell support the item name and app version. Not all controls use the same gesture.
Am I talking to a person? Can I ask for human review?
Automatic answers come from an AI assistant, not a person, and may contain errors. In the chat, ask for human review and explain what remains unresolved. To open support, tap SETTINGS → SUPPORT → Contact support once, or use the assistant menu in the header. Your message is recorded for the team to review. This does not guarantee live human support or a response time. You can also email suporte@callblockerx.com.br.
Who can see my data? How do I read the policy or delete my account?
Location sharing requires your activation and authorized contacts. Find my phone (Portuguese) is separate: it uses your Google Account and does not require sharing with contacts. Backups, routes and support use online services; not all data stays only on the device. See SETTINGS → INFORMATION → Privacy Policy. In SETTINGS → ACCOUNT AND PLAN, double-tap Delete account. Choose either a 90-calendar-day reactivation period or immediate permanent deletion. Reactivation requires explicit confirmation before the displayed deadline; signing in does not reactivate the account. Automatic deletion starts when the deadline expires. Deactivation revokes old location-sharing links, which are not restored on reactivation. You can request permanent deletion without waiting 90 days. On the website, /account-deletion/ provides account management options without requiring reinstallation. When direct access is enabled, use the Google account already linked in the app and explicitly confirm the action. For anonymous accounts, use the original app session. Email remains a fallback for access problems, with identity verification.
What do the blue route arrows and Mostrar pontos (Show points) do on the website?
The arrows show the records’ chronological direction, not live movement. Mostrar pontos (Show points) only shows or hides markers. Read the full guide to sessions, the map, line types and location-history limits.
How does the First steps assistant work?
In SETTINGS → SUPPORT, tap First steps once, or open it from the assistant menu in the header. It guides you through permissions, your Google Account, number verification, protection and your first backup. You can do this later or choose to restore a backup. Permissions and confirmations still require your choice.
Which Anti-Spam profile should I choose?
Basic uses the less restrictive preset settings. Strict applies more restrictive criteria and may block legitimate calls. Custom lets you adjust the limits to your needs. Check the displayed values before applying a profile and review the reasons in LOGS. No profile guarantees that all spam will be detected or that every incorrect block will be avoided.
How do I link my Google Account?
In SETTINGS → ACCOUNT AND PLAN, double-tap Google Account. In the window, tap Link Account once and complete Google sign-in on your device. Then check the Linked status and email shown on the card. Linking does not purchase a paid plan or verify your number automatically. Never send passwords, codes or tokens to support.
How do I verify or change my number?
Link your Google Account. Open SETTINGS → ACCOUNT AND PLAN and double-tap My number. With no linked number, follow verification; otherwise, choose Verify current number or Change my number. When changing it, check the selected country and enter an area code and number you control. Availability depends on the server. Opening the screen sends no SMS; continuing may require confirmation of the same linked Google Account and Firebase verification, which can use SMS and incur costs. Enter the code only in the app. This does not change the number on your Google Account.
Where can I check default spam screening and call permissions?
In SETTINGS → SETTINGS, below Default, tap the Default spam screening card to review it. Android must select Call Blocker X for call screening; Contacts permission also lets it forward calls from saved numbers. Linking an account and verifying a number do not grant these permissions or recover earlier calls. If your Android does not offer this selection, recording every call cannot be guaranteed.
How can I display classification and risk while the phone rings?
In SETTINGS → NOTIFICATIONS, double-tap Incoming call identification to turn it on or off. A single tap opens its Android notification channel. The native alert uses available data while an allowed call rings; local data may be outdated, and Not assessed does not mean safe. Display depends on Android and notifications, without overlay permission. The alert does not block or report numbers. To end the call, use the Android call screen.
The Privacy Policy and Account Deletion pages are available in Portuguese.
Find my phone (Portuguese): session, map and location history
For your security, the session ends after 10 minutes without interaction. A warning appears during the final minute, with a Continuar conectado (Stay signed in) button. Clicks, keyboard use and scrolling reset the timer; automatic location updates do not. Signing out or letting the session expire removes the map, coordinates and location history from the screen.
The map opens in Híbrido (satélite e ruas) (Hybrid: satellite imagery and street labels). You can choose Mapa (Map) under Camadas (Layers). The displayed time and accuracy refer to the last received position, which may not be the current location.
Location history covers up to 24 hours, with variable sampling intervals. The dashed line approximately connects positions selected by quality; it is not the exact route along streets. Low-accuracy measurements, jumps and gaps may break the line; small stationary fluctuations are reduced in the drawing. The last position may remain visible as approximate, with its time and accuracy circle. We do not reconstruct missing sections. Older routes do not gain points that were never recorded.
Since version 96, with Find my phone (Portuguese) enabled and permissions granted, the app stores positions offline in encrypted local storage for up to 24 hours, limited to 10,000 points. In version 97, it requests positions approximately every 5 seconds during slow movement, 3 seconds during faster travel with reliable speed readings and 2 seconds while confirming a turn; it reduces the frequency when stationary. Not every measurement is stored: accuracy, displacement and time are still evaluated. Direction changes of about 30° confirmed by reliable measurements preserve actual points before, during and after a turn, in both Find my phone (Portuguese) and My route. History uses a window of about 30 seconds to organize these points; the last received location is handled separately. If Android abruptly terminates the process, recent candidates not yet stored may be lost. More frequent collection may use more battery. After reconnecting, it attempts to sync points with their original capture times. GPS and Android restrictions may cause gaps; missing corners or points are not invented. Without a connection, the website only shows data already received, not live tracking. Disabling Find my phone (Portuguese) discards its pending local points.
Meus trajetos (My routes) shows your own routes recorded in the app, synced to the same account and still available. It does not include routes received from contacts. Select a route to display it on the map. Under Mais opções (More options), Atualizar painel (Refresh panel) retrieves data already sent; it does not request a new position. Apagar histórico de posições (Delete location history) requires confirmation and does not delete routes in Meus trajetos (My routes).
The map page is available in Portuguese. Routes are blue. The arrows are static and indicate the direction of the records in chronological order, not live movement. Saved routes use a solid line; location history uses a dashed line. Mostrar pontos (Show points) is off by default and resets to off when you sign out or the session expires. It only shows or hides markers for positions used in the drawing: it does not change or delete records or improve accuracy. The drawing does not calculate a route along streets, invent points or fill gaps without data.
