How To Add A Contact On WhatsApp

WhatsApp is one of the most popular messaging apps with more than two billion users across the world. You can install the app for free and use it to make voice and video calls, share media files or documents, among other things.  

In order to use all the WhatsApp features, you need to check whether your contacts are also using WhatsApp. Once you install WhatsApp on your tablet or phone, you can check to see who among your family or friends are already using the app.

However, not all your contacts will appear on the list, which could mean that they’re not using the app, or you probably haven’t added them to your phonebook yet.

We’ve put together this guide to help you add a contact on WhatsApp so you can connect with them, and start chatting right away.

How To Add a Contact On WhatsApp

You can add a contact on WhatsApp through your phone’s address book or through a contact card. If you received a message from someone who isn’t on your contacts list or phonebook, you can also add the contact directly through WhatsApp.

How To Add a Contact On WhatsApp Using a QR Code

A WhatsApp QR code is an easier way to add contacts on WhatsApp.  You can share your WhatsApp QR code with the contact you’d like to add, and they’ll simply scan the code to be added on your contact list.

Note: The WhatsApp QR code only expires if you reset it or if you delete your WhatsApp account. It’s important that you trust whoever you’ll share the QR code with because it’s possible for someone to share it with others who can add you as a contact by scanning the code.

Keep Your Contacts Close

WhatsApp is a great app for staying in touch with your loved ones wherever they are in the world. It’s not always easy to add your contacts within the app itself, but with these steps, you’ll have all your contacts at your fingertips without having to search for or import them.

How To Set Up & Use Smart Lock On Android

Smart Lock is a security feature in Android that lets you easily and quickly unlock your Android-based phones and tablets. You can specify the conditions for when Smart Lock should keep your phone unlocked.

Smart Lock has several unlocking conditions that you can configure and use. When you satisfy one of these conditions, your phone becomes or remains unlocked. As soon as your phone detects that these conditions aren’t fulfilled, your phone locks again. You then need to unlock your phone like you normally do.

How To Set Up On-Body Detection In Android Smart Lock

On-body detection is a Smart Lock condition that keeps your phone unlocked when your phone is on you. This condition uses the built-in accelerometer and other sensors on your phone to recognize if the phone is moving or is sitting idle (motionless).

When you’re using your phone and your phone is in motion, the on-body detection condition gets fulfilled and your phone remains unlocked. If you put down your phone and there’s no activity, this condition becomes false and your phone gets locked.

  1. Open the Android Settings app.
  2. Scroll down and tap the option that says Security & lock screen.
  1. Tap Smart Lock on the following screen. This is where you configure various Smart Lock methods.
  1. Enter the PIN for your device and continue.
  2. Tap the On-body detection method on the screen that follows.
  1. You’ll see a toggle named Off at the top. Turn this toggle to the ON position to enable the On-body detection method.
  1. Tap Continue in the prompt to enable the method.

This method doesn’t check the user identity. Because of that, your phone will remain unlocked and usable no matter who’s using it. You may only want to use this method when you can be sure you’re the only person with access to the phone.

You can disable this feature by turning the toggle to OFF in the second to last step above.

How To Set Up Trusted Places In Android Smart Lock

If you want to keep your device unlocked at certain locations, you can use the Trusted Places feature. This feature lets you manually define your trusted locations. When you’re in those locations, your phone remains unlocked.

When the phone detects you aren’t in a trusted location, your phone will get locked.

This feature uses Google Maps and your phone’s GPS to help pinpoint your location. You can add multiple locations as trusted places.

  1. Launch the Settings app.
  2. Tap Security & lock screen followed by Smart Lock.
  3. Tap the option that says Trusted places.
  1. You can now add a trusted place to this method. Tap the Add trusted place option to do that.
  1. You’ll see the Google Maps screen. Drag the marker to the location that you want to use as a trusted place. Then tap Select this location at the bottom.
  1. Your phone will ask you to enter a name for your location. Enter a name that helps you recognize this place and tap OK.
  1. Select the Add trusted place option again to add another location.
  2. Smart Lock will keep your device unlocked when you’re at your specified locations.
  3. You can edit your trusted places if your address has changed. Tap a location and select Edit Address. Then choose a new location and tap Select this location.
  1. If you no longer want to keep a location in trusted places, tap that location and select Delete.

How To Set Up Trusted Devices In Android Smart Lock

The trusted devices method in Smart Lock lets you keep your phone unlocked when one of your trusted devices is connected to your phone. You can use this method with any of your Bluetooth-enabled devices.

This includes your car’s Bluetooth system, headphones or earphones, smart watches that use Bluetooth, and so on. Keep in mind that since this method uses Bluetooth, your Bluetooth devices must be within 100 meters from your phone to keep it unlocked.

  1. Head to Settings > Security & lock screen > Smart Lock on your phone.
  2. Tap the Trusted devices option.
  1. Select the Add Trusted Device option at the lower-right corner.
  1. Your phone will show the Bluetooth devices you’ve used in the past. Tap one of these devices to connect to that device. If you want to use a device that you haven’t connected to your phone before, you need to go into your Settings and pair with that device first.
  1. Tap Yes, Add in the prompt on your screen.
  1. When that Bluetooth device connects to your phone, your phone will unlock and remain unlocked.
  2. You can add another trusted device by tapping Add trusted device and following the same instructions as above.
  3. If you don’t want to use your Bluetooth device to unlock your phone, tap your Bluetooth device in the list and choose Remove Trusted Device.

Note: Always keep your trusted Bluetooth devices with you, as anyone who has access to any of your trusted devices can use them to unlock your phone.

How To Set Up Facial Recognition In Android Smart Lock

The facial recognition feature works by scanning your face and matching it with saved face details. If the face matches, your phone unlocks.

Most phones will display a recommendation that this method is less secure than a PIN or password method. Also, someone whose face is similar to yours can unlock your phone. Therefore, you should use this method carefully.

  1. Go to Settings > Security & lock screen > Smart Lock on your device.
  2. Select the Trusted face option.
  1. Tap Set Up at the bottom-right corner to start setting up the method.
  1. Read the recommendations for how you should scan your face with your phone’s camera. Then tap Next at the bottom.
  1. You’ll see your camera’s view. Point your camera to your face and make sure your face fits inside the circle.
  1. Wait for your phone to scan and add your face to the system.
  2. Tap Done when your face is added to Smart Lock.
  1. To use this feature, simply turn on your phone. Look at your front camera and your phone will unlock.
  2. If your phone doesn’t unlock for some reason, tap Improve face matching in Smart Lock to take another photo of yourself in better light conditions.
  1. You can disable this feature by tapping Remove trusted face. This’ll remove your face details from your phone.

If your phone won’t unlock with your face, you can use your PIN or pattern as an alternate unlock method.

Many people consider entering a PIN or swipe pattern to unlock a phone as boring and time-consuming. Smart Lock removes that hassle and keeps your phone unlocked in predefined trusted situations.

How do you unlock your phone? Do you use a Smart Lock feature or do you prefer the old and traditional PIN or pattern method? Let us know in the comments below.

Voicemail Not Working On Android: A Troubleshooting Guide

While it might seem impossible to disconnect yourself from the real world, you shouldn’t be afraid to switch your cell phone off every once in a while. After all, messages you don’t see will be waiting for you, and any missed calls will go straight to your voicemail for you to pick up and deal with later.

That is, of course, if your voicemail service is working correctly. If your voicemail is not working on your Android device, you may need to set up or tweak your settings to get them working again. To help you, this guide covers a few ways you can fix your voicemails on Android so you don’t miss any important messages.

Check Your Voicemail Settings

First, you should make sure that your voicemail settings are correct. You can check these settings for yourself using the Phone app on your device.

This app (and its settings menu) will look slightly different, depending on your device model and Android version. These settings have been written with a Samsung Galaxy S20 running Android 10 in mind, but should be similar for most other Android devices.

  • Open the Phone app on your phone to begin. Tap the three-dots menu icon in the top-right.
  • From the drop-down menu, tap the Settings option.
  • In your Call Settings menu, click the Voicemail option.
  • From here, you can double-check how your voicemail is configured. For instance, make sure that the correct network carrier is selected under the Service provider section. 
  • Your carrier should have a voicemail number. This is the number your device will call to hear your voicemail. Check that this is correct under the Voicemail number section.
  • If you’re not being notified when you receive new voicemails, check your voicemail notifications are set correctly under the Notifications section.

The voicemail settings shown here should be applied automatically when you insert a SIM card into your cell phone, but they could have become corrupted or outdated. If you’re unsure whether these settings are correct, you may need to look at one of the additional fixes below.

Request New Voicemail Settings From Your Carrier

You may believe that your voicemail settings are correct, but there can sometimes be conflicting settings on your cell phone that can cause issues with voicemail not working on your Android device. To help overcome these issues, you can request new settings from your carrier to set up your voicemail.

How you do this will depend on your carrier and location. You may also be using a visual voicemail service that allows you to view voicemail messages in a list to listen, save, or delete using a voicemail app.

This service can often cost you extra, so if you’ve been downgraded (or upgraded), you may need new settings sent to your device for it to work. The best way to manually update these settings is to visit the website for your network carrier for additional information or to contact your carrier directly.

In many cases, you may be able to receive your settings in an SMS message from your network. Many networks allow you to request these settings with a message sent from your own cell phone. Your carrier will then respond with a message containing the new settings which can then be applied to your device.

Update Your Carrier’s Voicemail App

Depending on the voicemail service you have, you may have a carrier-issued voicemail app installed on your device for you to use your voicemail service. This is especially true if you’re using a next-gen visual voicemail service.

If a carrier-issued app isn’t working, you may need to check for updates. App updates often come with new features or bug fixes that can help resolve common issues. If your voicemail app breaks, this may be the result of an issue that your carrier has since resolved.

You can check for updates to this app using the Google Play Store. If your carrier has updated the app, you may need to manually update it, as some apps with sensitive permissions require this.

Call Your Carrier Voicemail Inbox

All cell networks have a voicemail number that you can manually call to access your voicemail inbox. Calling your voicemail number manually can help you determine if your inbox is active and working correctly.

This number is always available for you to use, so if you’re struggling with a voicemail app or notifications not working on your Android, you can call your carrier’s voicemail number to check your messages manually.

For instance, you may need to follow some additional steps to switch on your voicemail. You may need to confirm a message for your voicemail before calls are accepted, or your inbox may be full, preventing any extra messages from being saved.

If you can call your voicemail number, listen to messages, and configure your settings, this would suggest that your voicemail is working and any issue with it is located on your device.

Use A Third-Party Voicemail App

While this may not work for all network carriers, it may be possible to install a third-party voicemail app. This could help you bypass any issues you have with calling your voicemail manually or with a bug-ridden carrier app.

Several third-party voicemail apps are available for you to try in the Google Play Store. Note that some of these apps may not work in your locale or with your particular voicemail service, so you’ll need to try them out first.

If you have a visual voicemail service, apps like My Visual Voicemail and Voxist can be used to set up and use it. Apps like these come with additional features, such as support for voicemail transcription, allowing you to quickly view your voice messages as text messages instead.

Contact Your Carrier For Support

If your voicemail settings still aren’t working, it could indicate an issue with the service provided by your network carrier. At this point, the best thing you can do is speak to your carrier to ensure that there isn’t a fault or issue that needs to be resolved with further technical support.

If there is a fault, your carrier can investigate and resolve the issue. They may also be able to offer additional support to set up and configure the voicemail on your Android device, if required.

Staying In Contact Using Android

If your voicemails aren’t working on Android, then the fixes above should help you solve the problem. In many cases, an update to your carrier’s voicemail app or settings can resolve the issue, but don’t forget to call your voicemail number to check if it is set up correctly.

Once you’ve set up your voicemail, you’re free to switch off when you need to. There are other ways you can stay in contact, however. There are a number of free messaging apps for Android you could use or, if you’re looking to chat face-to-face, you could set up a Zoom meeting on your smartphone instead.

How To Find Your Wifi Password On An Android Device

We connect to so many different networks and the password usually gets entered just once. So what would you do if you forgot the WiFi password? Having a good password safe would prevent this problem, but you can also find the WiFi password off your Android phone. It’s easier than you might think.

For iPhone users, we’ve got an article on how to see the WiFi password on an iPhone too.

Find The WiFi Password On a Pixel Phone

If you’ve got a Google Pixel phone with Android 10, this is the easiest way possible to find your WiFi password. 

  1. Go to Settings > Network & Internet > WiFi .
  2. Tap on the name of the WiFi network you want to recover the password from to get to the Network Details Screen.
  3. Tap on the Share button. It will ask you to authenticate with a fingerprint or PIN.
  1. The phone will display a QR Code. Right below that is the WiFi password for that network.

Find  The WiFi Password On Other Android Phones

If you’ve got a non-Pixel phone with Android 10, it’s slightly more complicated but still very simple.

  1. Go to Settings.
  1. Tap on Connections.
  1. Tap on Wi-Fi.
  1. At the bottom-left of the screen, tap on QR Code.
  1. Take a screen capture of the QR Code.
  1. Using a QR Code scanner, like TrendMicro’s QRScanner, load the screenshot. Do this by tapping the QR code icon in the bottom-left corner.
  1. You’ll see the password now. In TrendMicro QRScanner, it shows in the 2 spots highlighted by the red rectangles below. 

Find The WiFi Password On Android 9 & Older Phones

If your Android phone runs Android 9 (Pie) or an older version of Android, finding the WiFi password is more difficult. You’ll need to root your phone first. That means giving yourself the highest access level possible. 

We have articles on how to root a Pixel, Galaxy, or Nexus phone. Then you’ll need to install some software on your computer and be able to connect your phone to the computer. 

  1. Enable Developer Mode on your phone. Go to Settings > System > About Phone then scroll down to Build number.
  1. Tap on Build number 7 times. You’ll see the message You are now a developer! 
  1. Go back one screen and scroll to Developer options. Go into that.
  1.  Scroll down to USB debugging and turn it on.
  1. Install Universal ADB Drivers on your PC. This helps your computer talk to the Android over a USB connection. Make sure your USB cable is for data transfer, not just charging.
  2. Download and install the Minimal ADB and Fastboot Tool on your PC.
  3. Connect the phone to your computer and open the Minimal ADB and Fastboot app. It opens as a command prompt.
  1. Type in the command <pre>adb pull /data/misc/wifi/wpa_supplicant.conf</pre> and press Enter.
  1. The command will copy the wpa_supplicant.conf file to your PC in the same folder Minimal ADB and Fastboot is installed in. In File Explorer navigate to that location.
  2. Open the file with Notepad and you’ll find the WiFi password.

Android WiFi Password Reveal Apps

You may be tempted to download a password recovery app. After reviewing several of the WiFi recovery apps listed in the Google Play store, we couldn’t find one that we would trust. 

Some have decent ratings, but the reviews seem fake. You’ll also find that they require you to root your phone. Even if they did work, should you really trust them? Are you sure they’re not sending your information somewhere they shouldn’t? We recommend avoiding these apps. 

Still Can’t Recover The WiFi Password?

Recovering the WiFi password on your Android phone is really just a convenience. You can find the WiFi password using the Command Prompt in Windows, if the computer can connect to the WiFi. If the methods above don’t work for you, then reset the WiFi password on your router

If it’s not your WiFi router, then ask the person who manages it for the password. If you don’t own the router, or you don’t want to talk to the person who does, you probably shouldn’t be using the WiFi anyway.

Get a Clean Android Phone With 10 Apps That Work

If you’re looking to clean up your Android phone, get rid of malware, or try to squeeze extra performance out of your device, a phone cleaner app can help.

These apps aren’t some kind of magic bullet that will resolve all of your performance issues, but they can certainly help to free up space used by files and apps you weren’t aware of, and give you an overview of how your phone is performing and why.

There are dozens of good apps for this, so it can be hard to navigate the app store to find the best. We’ve made that easier for you by listing the 10 Android phone cleaner apps that actually help you have a clean Android phone.

Avast Cleanup

Easily the most downloaded Android cleaner app is Avast Cleanup, developed by Avast software. Avast Cleanup is one of the most popular apps for getting a clean Android phone. Upon opening, Avast Cleanup will quickly scan your device to find out just how much space you can free up.

Avast Cleanup takes you through everything step by step, so if you don’t really know what you’re doing, it can be a good alternative to other Android cleaner apps. Just tap start here after opening Avast Cleanup and go through each step.

You can then quickly delete everything Avast Cleanup suggests, or check each category to manually select and deselect options for deleting. 

Once you’ve done your first scan, you’ll have access to different options like quick clean, boost memory, and tips. Boost memory can hibernate apps to help improve your overall performance and tips can scan your device to give you performance and storage tips based on your own device. 

Avast Antivirus offers a Premium Plus subscription for £10.49 a year that also includes Avast Security premium.

Norton Clean

Developed by the same team behind Norton antivirus comes Norton Clean, an app designed to help you learn how to clean your Android phone. 

Norton Clean gets straight into the action by scanning your phone files and listing any junk files. You can then go through the files one by one and choose whether you want to keep them or not. 

Norton Clean also gives you a list of all of your apps so that you can quickly see what’s installed and find apps you don’t really need anymore. It beats browsing through the default UI because you can sort apps by install date or last use.

All-In-One Toolbox

All-In-One Toolbox is an Android cleaner app that can help to free up storage, clean your Android cache, and boost your device. 

The home screen for All-In-One Toolbox will showcase your RAM and CPU usage. You can tap on each option to find out how to reduce your CPU and RAM usage by stopping apps. Note that it’s not worth reducing your RAM, because Android has smart RAM management, which means the more full your RAM is, the faster it will switch between apps, so it’s best not to mess with it.

You can also quickly go through your system files and cache to clear up space on your device. It takes just a few seconds to scan everything. The battery saver feature can also help you to reduce your battery usage by closing apps that are consuming battery in the background.

AVG Cleaner

Created by the same team behind AVG antivirus. AVG Cleaner actually has a very similar experience to Avast Cleanup. We wouldn’t be surprised if AVG teamed up with them to develop the app.

You’ll be taken through the initial cleanup stage once installing and then after that you’ll gain access to quick clean, boost memory, and tips

You may prefer to get AVG Cleaner instead of Avast Cleanup if you already have an AVG antivirus premium subscription. 


CCleaner is another clone of the Avast Cleanup app. You get the first initial system scan upon install, then access to the boost memory and tips features.

The only reason you’d consider this one is if you’d like the premium features for cheaper. It costs just £1.49 per month, or £5.99 per year. Of course, you won’t get an antivirus included, but it’s still cheaper than Avast and AVG.

Droid Optimizer

Another popular Android cleaner app is Droid Optimizer. You’ll find a number of options available to free up storage and boost your Android phone performance.

First up, Droid Optimizer has a 1-touch speed up feature. With this you can quickly free up storage, stop apps that are eating up resources in the background, and clear the cache.

You can also use the clean up feature to delete the system cache, download files, and other unwanted files taking up space on your device. App manager lets you check all of your apps and determine which ones are worth deleting to improve performance and free up more space. 

Droid Optimizer even has a privacy detector that can be used to check what permissions each app has and put a stop to those that may have unwanted access to your phone.

Fancy Booster

Fancy Booster is another phone cleaner app designed to help clean your Android phone. You can use it to clean up junk files and apps, remove the cache, and boost your phone performance.

Once installed, you’ll have a page appear that shows how much RAM and storage your device is currently using. From there, you can use a variety of tools to get your device working better.

Phone Boost, for example will take a look at which apps are using the most resources and offer an option to remove their storage footprint. With CPU cooler, you can quickly stop apps from running in the background. 

What we like about Fancy Booster is that it has more functionality than most other Android cleaner apps. For example, you can even use it to quickly manage which of your apps get notifications.

Phone Speed Booster

With Phone Speed Booster installed, you’ll be able to quickly remove junk files by scanning all apps on your phone. The amount of storage you’ll be able to save can be quite significant.  

With the battery saver option, you can hibernate apps so that they don’t use battery whilst running in the background. You can also use the CPU cooler feature to see if your phone is having issues with overheating, and if so, you can close down apps to put less strain on your CPU.

Virus Cleaner – Antivirus Free & Phone Cleaner

Virus Cleaner is a great app if you want to free up storage space by deleting junk files, manage your notifications, save battery life, and also stop Android malware.

Most of the functionality in Virus Cleaner is the same as other apps. You can run a scan to see files that are taking up space and then remove them, or run a scan to see if any apps are causing your phone to overheat and then force-stop them.

With Virus Cleaner’s virus scanner feature, your apps will be scanned and any potential threats will be revealed. If any threats are found you’ll be warned and you’ll then be able to delete them to protect your phone.

One Booster

We like One Booster because it gets straight to the point without requesting too many permissions. A quick scan will happen the moment you start the app and then you’ll be told how much space you can save by deleting junk files.

After that, you’re given access to four features – phone boost, battery saver, security, and CPU cooler.

When you use either CPU cooler or battery saver, One Booster will automatically hibernate apps to reduce battery and CPU usage. With the security feature, your apps will be scanned to highlight any potential threats.

Finally, phone boost will go through apps once more and hibernate those that may be causing issues with your performance at that very second.
