only allow calls from contacts android
In today’s digital age, smartphones have become an essential part of our daily lives. From making calls, sending messages, to accessing the internet, smartphones have made our lives more convenient and connected. However, with this convenience comes the risk of unwanted calls and messages from unknown numbers. To combat this issue, most smartphones now come equipped with the option to only allow calls from contacts. This feature is particularly useful for those who wish to avoid spam calls and maintain their privacy. In this article, we will discuss the benefits and drawbacks of this feature and how to enable it on your Android device.
Before we delve into the specifics of this feature, let us first understand what it means to only allow calls from contacts. As the name suggests, this feature allows your phone to ring only when you receive a call from a number that is saved in your contacts. This means that any calls from unknown numbers or numbers that are not saved in your contacts will not ring on your device. Instead, they will be automatically redirected to voicemail or simply not show up as a missed call. This feature can be enabled for both incoming calls and messages, providing you with complete control over who can contact you.
One of the biggest advantages of only allowing calls from contacts is the elimination of unwanted and spam calls. We have all experienced the frustration of receiving incessant calls from telemarketers, scammers, and other unknown numbers. These calls not only disrupt our daily activities but also pose a security threat. By enabling this feature, you can effectively block such calls and protect yourself from potential frauds and scams. Additionally, this feature can also help in reducing distractions and interruptions, especially during important meetings or tasks.
Another benefit of this feature is the protection of your privacy. In today’s digital world, our personal information is more vulnerable than ever. With the rise of data breaches and online scams, it is crucial to safeguard our personal information. By only allowing calls from contacts, you can ensure that your phone number is not easily accessible to strangers. This can also be helpful in avoiding unwanted attention from acquaintances or ex-partners. Moreover, this feature can also be useful for parents who want to restrict their child’s incoming calls to only known contacts.
However, there are certain drawbacks to only allowing calls from contacts. The most significant being the possibility of missing important calls from unknown numbers. While this feature can effectively block spam calls , it can also block important calls from businesses, doctors, or other emergency services. In such cases, you may have to manually add the number to your contacts or temporarily disable the feature to receive the call. Moreover, this feature is not foolproof as scammers and telemarketers often use different phone numbers to contact people.
If you have an Android device, enabling the option to only allow calls from contacts is a simple process. The steps may vary slightly depending on your device’s manufacturer and version of Android, but the general process remains the same. Firstly, go to your device’s Settings and select the “Sound and Vibration” or “Sounds and Notifications” option. From there, choose “Do Not Disturb” or “Notifications” and then select “Allow Calls From.” Here you will have the option to choose between “Contacts Only,” “Favorite Contacts Only,” or “Starred Contacts Only.” You can also choose to enable this feature for messages by selecting “Allow Messages From” and following the same process. It is important to note that this feature may not be available on all Android devices.
In addition to enabling this feature on your device, there are also several third-party apps available on the Google Play Store that offer more advanced call blocking features. These apps allow you to create a custom block list, block calls from specific area codes, and even create a whitelist of numbers that can bypass the block list. Some popular apps in this category include Truecaller, Call Blocker, and Mr. Number. However, it is essential to research these apps before downloading them, as they may require access to your personal information and call logs.
In conclusion, only allowing calls from contacts is a useful feature that can help in reducing unwanted calls and protecting your privacy. While it may have some drawbacks, the benefits outweigh them, making it a must-have feature for many smartphone users. With the constant rise in spam and fraudulent calls, this feature provides a sense of security and control over your device. So, if you have been receiving a lot of unwanted calls lately, it might be time to enable this feature on your Android device and enjoy a more peaceful and secure calling experience.
can face id work with eyes closed
Face ID, also known as facial recognition, is a biometric technology that allows users to securely unlock their devices or access certain features by scanning their face. The feature was first introduced by Apple in 2017 with the release of the iPhone X and has since become a standard feature in most high-end smartphones. It uses a combination of hardware and software to create a detailed 3D map of a person’s face and then compares it to the stored data to verify their identity. While it is a convenient and secure way to unlock devices, one question that often arises is whether Face ID can work with eyes closed. In this article, we will explore this topic in detail and provide you with all the information you need to know.
To understand whether Face ID can work with eyes closed, we must first understand how it works. The technology uses a front-facing camera, known as the TrueDepth camera, to scan a user’s face. This camera contains a dot projector, an infrared camera, and a flood illuminator. The dot projector projects over 30,000 invisible dots onto the user’s face, creating a detailed 3D map. The infrared camera then captures the dot pattern and sends it to the A11 Bionic chip, which uses machine learning algorithms to compare it to the stored data and determine whether it is a match.
The flood illuminator is responsible for illuminating the user’s face with invisible infrared light, making it possible for Face ID to work in low light conditions. This is one of the main advantages of Face ID over other forms of biometric authentication, such as fingerprint scanning, which requires a well-lit environment to work properly. However, this also brings us back to the question at hand, can Face ID work with eyes closed?
The short answer is yes, Face ID can work with eyes closed. In fact, it is designed to work in this way. Apple has stated that Face ID is designed to work with your eyes closed, or even if you are wearing glasses, contacts, or sunglasses. This is because the technology is not solely reliant on the eyes for verification. It takes into account other features of the face, such as the shape of the nose, mouth, and chin, to create a unique 3D map. This means that even if your eyes are closed, as long as the other features of your face match the stored data, Face ID will still work.
However, there have been reports of Face ID being bypassed by siblings or twins who have a similar facial structure. This indicates that the technology is not foolproof and there is a margin for error. In these cases, it is possible that Face ID may not work with eyes closed, as the other person’s face may have features that are too similar to the stored data. This is why Apple recommends setting up an alternate appearance for people who may have a similar face structure, such as a twin.
Another factor that can affect the performance of Face ID is facial hair. If you have a beard, mustache, or any other facial hair that significantly changes your appearance, it is recommended to set up an alternate appearance for such cases. This is because the technology may not be able to create a 3D map of your face accurately, leading to Face ID not working with eyes closed. Similarly, if you have a drastic change in appearance, such as growing or shaving a beard, it is recommended to re-enroll in Face ID to ensure its accuracy.
One of the main concerns with Face ID is privacy and security. Many people worry that their face data may be compromised or misused. To address these concerns, Apple has stated that all face data is stored securely on the device and is not shared with any third parties. The data is also encrypted and can only be accessed by the A11 Bionic chip, making it nearly impossible for anyone to steal or misuse the data. Additionally, Face ID is designed to only work when the user is looking directly at the device, reducing the chances of someone unlocking your device without your knowledge.
Another feature of Face ID is the attention aware feature, which requires the user to be looking at the device for it to unlock. This adds an extra layer of security, as someone cannot simply hold the device in front of your face to unlock it. This feature also ensures that Face ID will not work with eyes closed, as the technology requires the user to be looking directly at the device for it to unlock.
In conclusion, Face ID can work with eyes closed, as it takes into account other features of the face to create a unique 3D map. However, there is a margin for error, and in some cases, it may not work with eyes closed. This is why it is recommended to set up an alternate appearance for cases where Face ID may not work, such as identical twins or significant changes in appearance. Overall, Face ID is a secure and convenient way to unlock devices and is continuously improving with each new release.
how to get facebook dating back on my phone
facebook -parental-controls-guide”>Facebook has been a dominant force in the world of social media for over a decade now. It has revolutionized the way we connect and interact with people, and has become an integral part of our daily lives. With the constant updates and new features being added, Facebook continues to evolve and cater to the changing needs of its users. One such feature that has recently gained a lot of attention is Facebook Dating, a platform for finding and connecting with potential romantic partners within the Facebook app itself. However, due to certain changes, some users have reported that they are unable to access Facebook Dating on their phones. In this article, we will discuss how to get Facebook Dating back on your phone.
Facebook Dating was first launched in 2019 in select countries and has gradually expanded to other regions. It is designed to help users find meaningful relationships, rather than just casual hookups. The platform uses Facebook’s vast amount of data to suggest potential matches based on your interests, preferences, and mutual friends. It also has features such as Secret Crush, where you can express interest in a Facebook friend without them knowing, and Virtual Dates, which allows users to video chat with their matches within the app.
So, if you’re wondering why you can’t find Facebook Dating on your phone, there could be a few reasons for that. The first and most common reason is that the feature is not yet available in your country. As mentioned earlier, Facebook Dating was initially launched in select countries and is gradually expanding to others. So, if you’re living in a country where it hasn’t been rolled out yet, you won’t be able to access it on your phone.
Another reason could be that you are not using the latest version of the Facebook app. Facebook Dating is a relatively new feature, and it requires the latest version of the app to function properly. So, if you haven’t updated your Facebook app in a while, you might not be able to see the Dating option on your phone. To update your app, go to the Google Play Store (for Android users) or the App Store (for iOS users) and search for Facebook. If there’s an update available, click on the ‘Update’ button.
If you’ve checked the above two reasons and still can’t find Facebook Dating on your phone, then it’s possible that you’ve accidentally turned off the feature. Yes, Facebook Dating can be turned off, just like any other feature on the app. To check if it’s turned off, go to your Facebook app and click on the three horizontal lines on the top right corner. Scroll down and click on ‘Dating.’ If it’s turned off, tap on the toggle button to turn it on.
Another thing to keep in mind is that Facebook Dating is only available on the Facebook app, not on the desktop version. So, if you’ve been trying to access it through your computer , that’s why you can’t find it. Also, Facebook Dating is only available for users who are 18 years and above, so if you’re under 18, you won’t be able to access it.
If none of the above reasons apply to you and you’re still unable to find Facebook Dating on your phone, there could be a technical issue. In this case, the best course of action would be to contact Facebook’s customer support. You can do so by going to the ‘Help & Support’ section on your Facebook app or by visiting the Facebook Help Center on your web browser. Explain the issue you’re facing, and they should be able to assist you in getting Facebook Dating back on your phone.
Now, let’s say you’ve followed all the steps mentioned above, and you still can’t find Facebook Dating on your phone. In that case, it’s possible that Facebook has temporarily disabled the feature in your region. This could happen due to various reasons, such as low user engagement, technical difficulties, or privacy concerns. If this is the case, unfortunately, there’s not much you can do except wait for Facebook to re-enable the feature in your region.
However, if you’re determined to use Facebook Dating on your phone, there’s a workaround for it. You can change your Facebook account’s location to a country where Dating is available and access it from there. To do so, go to your Facebook profile and click on ‘About.’ Then, click on ‘Living’ and change your current location to a country where Facebook Dating is available. Keep in mind that this might not work for everyone, and it’s not the most reliable method. Also, this might violate Facebook’s terms of service, so proceed at your own risk.
In conclusion, Facebook Dating is a relatively new feature, and like any other new feature, it has its fair share of bugs and issues. So, if you can’t find it on your phone, don’t panic. Check if it’s available in your country, update your app, turn it on from the settings, and contact customer support if needed. If all else fails, you can always change your location and access it from there. With Facebook constantly working on improving and expanding the feature, it won’t be long before you can access it on your phone. So, sit tight and keep an eye out for updates. Happy dating!
