- Optional automatic call blocking. (This function should not be compatible with all phone models due manufucaturers modifications of the system)
How it works
- When some number calls, application shows phone number rating via security rating notifications (Alerts).
- Each rating is based on reviews in Community Database, your Phone Contacts (if not otherwise specified, taken always as POSITIVE) and your own ratings.
- All above is combined into single POSITIVE, NEUTRAL, NEGATIVE or UNKNOWN final rating.
- The YOUR RATINGS tab serves for composing of your own rating for any number - can be public or private, these are always prior to community rating.
- How the calls will be maintained and blocked can be configured in the SETTINGS tab.
Based on the Settings, the application can only display information about incoming/outgoing calls, or block them.
For those functions, application combines the information you have provided on the "YOUR RATINGS" tab (this info is a top-priority, so you can e.g. mark also a number stored within your Contacts as negative), with your mobile Contacts (by default marked as POSITIVE, second priority) and with the information from the Community database (stored off-line in your mobile) taken as third priority.
To provide those functions, the application must be still running in your device memory - user must check and assure this for some manufacturers.
This is the core app part where user can check the application functions and actions the application has taken. Log contains the Phone Call History, read from phone system log. Icon on the left side indicates the Phone Number Rating with following meaning:
Next icon informs you about call type and taken action:
|Successful Incoming Call|
|Missed Incoming Call|
|Blocked Incoming Call|
|Not Checked Incoming Call (Protection was not running)|
|Successful Outgoing Call|
|Missed Outgoing Call|
|Blocked Outgoing Call|
|Not Checked Outgoing Call (Protection was not running)|
- Phone Number Click : this action opens the Phone Number Details screen with detailed information and further actions: Call, Block, Rate and download reviews for the number.
- Phone Number Long Hold : if you hold a finger on the number for a while the context menu is shown with actions : Show Details, Call Number, Copy number to clipboard, and Web Search which opens our web page with the respective number.
- Call Button Click : will open the system phone log, where you can manage the log of phone calls history.
When you pull the Logs screen a bit up to show the first line and above, the upper line will display three Log dividers (you can click on each of them). When scrolling down, this line will hide automatically.
- PHONE : this list contains all calls as provided by your system phone log
- BLOCKED : this list contains only the blocked calls. Call them back if needed
- CHECKED : this list provides the list of all calls checked by our application
Use the 'Phone Number Details' screen or the 'Your Ratings' tab to add your own rating which will be used in alerts and blocking.
Some log lines can be marked with red text "Protection was not active!" or "Protection was not running". If this happens, please read the Protection is not active troubleshooting.
This screen is the core of the rating system used lately for blocking or allowing the calls. In this section you can:
- create POSITIVE, NEGATIVE or NEUTRAL (each private or public) rating for any number
- manage your created ratings - adjust or delete them
Your rating can be defined for a single number or multiple phone numbers by using a mask. Be aware when setting a rule for wide range of numbers. Always double-check the possibility of conflict with any other rule or Contacts.
- Rating Filter : (at the top of the screen) helps to filter the rating rules by phone number. Useful if you search for some specific number rule. Just tick on the line and fill any number or a part of it.
- User Rating Click : by clicking on any of your rating you open a screen for edition of the respective rating. There you can set the rating attributes, delete the rating, save it or cancel the changes.
- Plus Button Click : this action opens the screen for creation of new rating, see below the Phone Number Rating.
As stated above, you can simply override e.g. the Community database rating by creating your own rule for a specific number. On the other hand, you can simply create a blocking (=negative) rule even for a number stored in Contacts. Remember, the rating can be marked as PRIVATE - in that case it will not be visible on internet, will be stored purely in your mobile. Please never publish ratings for private numbers, always set them as PRIVATE. Also it is a best practice to create rule using the international area code, or to pick the exact number from LOGS screen and create the rating there. Unknown (hidden or masked) numbers can't be blocked by a rule, but can be blocked directly in the SETTINGS screen.
SettingsThis section contains main application settings.
In this section you can configure which incoming/outgoing calls should be blocked. Remember, in the Your Ratings screen you have set the additional rating sources next to the community database. Now we will decide what source we will use for the blocking functionality of the application and how.
- On the Community DB sensitivity bar you can select what level of protection according to the Community database you want. Just pick one of the levels from the bar (where default is 'Standard Protection') to tell the application how many negative ratings must exist for a negatively rated number to block the number when using the Community database rating.
- You can chose from 3 levels:
- High Protection: with this level just one admin-approved review is enough to take the action - which can cause also a number to be blocked with one possibly false positive/negative rating
- Standard Protection: this setting demands at least 3 admin-approved reviews to be existing in the database to take the action
- Lower Protection: high number of admin-approved reviews must exist to take the action, which means not so many calls will be blocked (you can improve this by writing your own public reviews), but this reduces the chance of blocking numbers rated just once or with minimum ratings
- We can set blocking rules for INCOMING and OUTGOING calls in respective sections, and SMS/MMS (using a 3rd-party application).
- Local negative rated numbers - if set, all numbers with your locally created and stored negative rating will be blocked
- Community negative rated numbers - if set, the community database rating is used, and all numbers negative rated by the community will be blocked
- Numbers not stored in Contacts - if set, all numbers unknown to you (not stored in Contacts) will be blocked
- Hidden numbers - if set, all masked/hidden numbers will be blocked
- Foreign numbers - if set, all calls from foreign countries will be blocked
- Also incoming SMS and MMS can be blocked. For this functionality, a compatible SMS manager must be installed, please read the help screen displayed if you check this item.
Combine the settings according to your needs. After the settings are made, check them for possible conflicts. Remember to check your own rating rules in the RULES tab and community database ratings for the specific number to be sure the app will serve you according to your wishes. Also remember that number stored in Contacts without any other rule (either Community, or your own) is automatically POSITIVE.
- Download reviews automatically
- If the "Download reviews automatically" is selected and your mobile is connected to the internet, the user reviews for some number are downloaded and displayed automatically when you open the call detail. This doesn't cost you any extra money, just the internet connection is used. If this item is not selected but the phone is connected to the internet, the user reviews can be downloaded also manually on the phone call detail screen. If the internet connection is poor, please use the Web Search function instead.
- Send anonymous stats about incoming calls
- If the "Send anonymous stats about incoming calls" is selected, the user gives us a possibility to send the incoming UNKNOWN numbers to the server - this means that only the number is send, without any further info, no personal data are never transferred from your mobile phone. Privacy is important to us, so we don't send stats about numbers stored in your Phone Contacts! Only unknown numbers are sent if this option is checked. This gives us a possibility to collect incoming unknown numbers from different sources - after then our team checks them and if same unknown number calls multiple people, we dig some info for it and create review with rating, which will be stored afterwards in your local database.
- Use pick and hang up to protect voice mail
- If call is blocked, the caller can still leave message to your voice mail. Optionally you can try to use Pick & Hang method to protect your voicemail. When selecting this functionality, the app will block incoming call by answering the call and hang up in the same second with one exception - application will not pick up call if the phone is in roaming mode. Please use this feature only if you are sure you will not be charged for picking up the incoming calls. This is experimental feature which does not work on all phone devices because it uses some workarounds due to missing Android support. If you are experiencing some issues, then please don't use this feature.
- Monitor Calls
- If enabled, protection is active and calls are monitored according the below configuration. Disabling can be used if you need to temporarily disable the call monitoring and the application without uninstalling it.
- Use PHONE_STATE listener
- If enabled, application uses PHONE_STATE listener for calls monitoring.
- Use PHONE_STATE Runtime Receiver
- If enabled, application uses PHONE_STATE Runtime Receiver for calls monitoring
- Use PHONE_STATE Receiver
- This is the first of the system receivers we use to catch the system process for establishing a call. If you have overall problems with calls not being checked by our application please switch this item on.
- Use NEW_OUTGOING_CALL Receiver
- This system receiver is used to catch the system process of outgoing call. For some devices, if you have problems with catching the outgoing calls please switch this item on.
In this section you can access additional information and export/import function. Protection statistics contains summary information of how many calls were checked and blocked, with figures for actual day/overall.
- How to Help Our Community opens page with hints how user can contribute to this project. If user selects one of the donation items, a GooglePlay page with donation will open.
- Online Manual opens the internet page with this manual.
- Report Issue : If some app problem requires the solution from out technical support, press this button and report screen will open. Write your name, check your e-mail address provided (or write it so we can contact you back) and write at least few words describing the problem (usually to state the exact number causing a problem will help). Reports with empty description will be deleted. The application logs will be added automatically.
- Export / Import shows screen for exporting and importing data. This section serves for the backup or restore of your app settings - please read the info on the screen.
Phone Number Details
This screen shows detailed information for selected phone number. Here you can find the overall number rating in the form of count of Positive/Neutral/Negative ratings and the category mostly used for this number (this information is stored off-line in the database of your mobile phone). You can also see how much positive/neutral/negative ratings the number received from community.
- Block helps you to create negative rating for this number for further blocking. To activate the blocking you have to enable blocking of negative rated numbers in the application Blocking screen.
- Rate shows the form for filling your new phone number rating - see below.
- Reviews loads and shows the community reviews for this number. This function requires internet access. If your own (personal) rating is presented, it is displayed automatically (all of them are stored in your phone) and EDIT button is presented for further edit of your review. After using this button the button will be greyed - you have downloaded the reviews already. Then it stays grey and the reviews loaded and displayed until the phone/application is restarted.
- Call Button Click initiates calling to the number.
Phone Number Rating
Phone number rating is the base for the alert and blocking functionality. User can enter this form either from LOGS screen by clicking on number and from the phone call detail by pressing the RATE button, or from the RATINGS screen by adding a new rating. You can rate single number or a group of numbers using mask (where star letter * is used as a replacement of any number(s) from the end of the number - do not use the * on the beginning of it). You can create either POSITIVE or NEGATIVE rating, or adjust/delete existing rating. Your own positive rating will override the negative community rating and your own negative rating can override positive community rating (and also the basic rule that numbers in Contacts are taken as positive by default). Please always check this logic when creating new rating. We recommend to create the rating rule from the LOGS screen, which assures to have the number in the exact shape as it called you. Also you can create 2 ratings for the specific number with AND without the international country code, which helps if the number comes in different formats.
Single or Group of numbers
Phone Number Rating can be defined for single number or for group of numbers. Group can be defined using * char at the end of the number. For example 800* will define rating for all numbers starting with 800. The PICK CONTACT enables you to pick a number from the list of Contacts and create a rule for it.
Public or Private
By default the rating is submitted to our community database for benefit of other users. If you don't want to make the rating for the respective number public, select this to avoid of sending it to our database - in such case the rating will be stored in your mobile only. In such case you don't have to fill the Category and Comment, just select the Rating and press SAVE.
In the Alert displayed for the phone call you can find all required information for making the decision to accept the call or hang up.
- Contact shows name of the contact associated with phone number (if available).
- Number shows phone number the alert is displayed for.
- Rating shows one of positive, neutral, negative or unknown rating.
- Category shows the mostly used Category for the respective phone number
- Community shows the total statistic counts of positive, neutral and negative ratings from the community
There are just a few permissions which must be granted to our app to keep the application running and to keep the protection fully working. This window provides easy way how to setup all required permissions.
Phone Contacts Permission (Android 6+)
Your Phone Contacts helps us to determine which calls are from 'unknown' sources. We also show phone contact names instead of phone numbers in 'Logs' tab and phone number details.
Call Info Permission (Android 6+)
We need to know what phone number is calling to you. Without this permission our app can't work.
Set Default Phone App (Android 7+)
Android 7 provides new way how to filter incoming calls. It is highly recommended to set our application as default 'Phone App' to get 100% protection against unwanted calls.
Draw Over Other Apps (Android 6+)
The application displays Alerts window during ringing phase. This can be done only with the 'Draw Over Other Apps' permission granted.
Accessibility Service (If not set as default phone app)
Enabling our Accessibility Service is very important to keep the protection active - most of the memory managers will keep such service running.
Disabling Background Optimizations
Most memory managers will try to kill any application on background if it seems not to be used actually - this will prevent our app from staying active. Disabling background optimizations for our app helps to keep the protection active.
Disabling Lock Screen Optimizations (Some Devices)
Most devices terminates unecessary apps every time you lock the screen. If your device has this feature, please add our application to the lock screen whitelist to keep the protection active.
Q: How to block phone number?
Create negative rating for the phone number and enable blocking of negative rated numbers. It can be done by 3 clicks : from LOGS screen select the respective call, press BLOCK button, click CANCEL and the private negative rating is created - check it then on the RATINGS screen.
Q: How to unblock phone number?
The reason why any number is blocked lies in one of the data sources - even the Community database marks it as negative, or your own negative rating is created. First check if there is some negative rating on the RATINGS screen for the number and delete it, then you can also create personal positive (or public) rating for it.
Q: Why I don't see any Alerts?
This is probably due our application has been stopped by system or 3rd party app. First please try to reboot your mobile, after the restart check if our app is running and if it has got all the necessary permissions. Please read the Protection is not active troubleshooting.
Q: Why blocking does not work for me?
First please try to reboot your mobile, after the restart check if our app is running and if it has got all the necessary permissions. Please read the Call Blocking does not work troubleshooting.
Q: Why the phone rings before blocking?
Depending on the speed of your phone hardware, software and the application settings it can happen that even a call that should be blocked will ring firstly and then it will be blocked. Uninstalling unnecessary applications which are running on background can improve the reaction time. Sometime helps just restart the phone.
Q: Why they still call even I'm blocking them?
Well, they don't know you use some blocking device. From the other side it seems the number called is just busy. Some robocallers can ignore this and will try to call again. Actually with the present versions of Android operating system it is not possible to play them some message to let them know you are not interested, if this changes in the future we will add this functionality.
Q: How to update my local database?
Your local database is stored in your mobile phone along with the application, It contains just the numbers and statistics data for them, without user reviews. The database is checked (and updated if necessary) each time you connect to the internet. Version of the actual database can be seen on the ABOUT screen in the bottom-right corner (text db:xxx). When you click on this text, the database will start a force update - user is notified by starting and finishing message.
Q: Can I protect my landline with Should I Answer?
Basically yes - you can re-direct the landline calls (or probably your provider can do it) to your mobile phone, where our app will check them. Or you can switch your landline to an internet-operating device if available for your country - any Android operating device can then have the Should I Answer app installed.
Protection is not active
If you have device with Android 7+, then you should have set our app as default Phone App. Please check the Settings. If all is set (no advice screen is offered in the 'Permissions Configuration') then you can try to restart the phone. If the issue persists please contact our support.
If you have device with Android 4,5 or 6 you must keep our application running! How to Keep Protection Active is one of the biggest challenges due insufficient support in the Android System. In most cases our application must be running to be able to react when new incoming call happens.
Unfortunately almost all phone manufacturers implements own battery optimisers which terminates background applications. You must manually whitelist our app to keep application running. It differs across manufacturers and often it's more complicated as it should be.
We are doing our best to help you with this settings, so we have created special 'Permissions Configuration' which is accessible via application Settings screen - you will find a button at the bottom of it. We also prepared article with manufacturer specific details. Feel free to visit the How to solve the 'Application is Disabled' issue
Call Blocking does not work
If you have device with Android 7+, then you should have set our app as default Phone App. Please check the settings. If all is set (no advice screen is offered in the 'Permissions Configuration') then you can try to restart the phone. If the issue persists please contact our support.
If you have older device then please check the Protection is not active. If the protection is active, the problem can be in manufacturers Android modifications in your phone.
Android 4,5 or 6 does not support call blocking. The only way how to block call is to use little hacking and call internal methods of Telephone interface. These methods are used across all call blockers available in the Play Store.
Using of internal interfaces means it's not 100% guranteed that the function works correctly on your phone. Any phone manufacturer internal modification can broke or change the functionallity.
