Which Call Blocker Is Your Personal Favourite?
Out of the 12 best spam call blocker apps for Android, my personal favorite is Calls Blacklist by Vlad Lee and Truecaller as both of these app are easy to use, allows me to save the blacklist, have caller ID functionality, provides scheduling, lightweight and does not consume much resources.
Which app did you install on your Android phone to block incoming calls? I would love to hear your experience in the comments section below. 🙂
This info is 3 yrs. Old. Are you going to update any time soon? Or have you just given up on this???
Hey Danielle, we recently updated the article. Why do you think its outdated?
Must be because of the older comments, he didn’t notice the ‘update date’ at the beginning 😛
#05 – CALL BLOCKER Is full of ridiculous. People have wrote in the comments on the play store, no annoying ads, but that’s a lie
Thanks for sharing your review about the call blocker by AndroidRock. And if you are not happy with the app then you are free to try other Android call blocker apps we have mentioned in the list.
Any call blockers that don’t require access to your contact list?
I used Calls Blacklist for a while because I needed to blacklist the first 6 digits of my own phone number due to spoofing by scammers, while allowing my wife to still get through. It worked well for a while, then stopped blocking anything a few months ago. Trying one of the others now.
Let us know if something worked for you.
I tried Should I Answer, but I lost the ability to add contacts to my contact list.
Try using any other app from this list.
@speedlever:disqus I hope you are aware that Should I Answer is hard to configure for an Android user who is looking for a simple app to block unwanted calls. I will recommend you to try the app mentioned in #1 i.e. Calls Blacklist. If you need any further help then feel free to let us know.
Thanks. I already snagged Mr. Number and am trying that now. I found SIA rather intrusive as it always wanted feedback about a call and was confusing to use on my Android phone.
If Mr. Number doesn’t work out for me, I’ll try Calls Blacklist. I was hoping to find an app that worked on iOS as well as Android since I live in a mixed family. 3 iPhones and my lone Android. 😉 I knew that SIA has both Android and iOS apps, so was hoping that would work for me.
Good to hear that, buddy! I hope Mr. Number work for you. A few of our readers found Mr. Number easy to configure 🙂
Remember, what works on iOS may not work well on Android as both operating systems are very much different from each other.
Understood. OTOH, we’ve had very good luck with Our Groceries which runs on both iOS and Android. So sometimes it works.
Give it a try after some time. It should work.
Our Groceries is a list type app and is from a completely different category that’s why it works on both. All it needs is a proper synchronization. Whereas, Call Blocking apps require some extra permissions as it is directly interfering with your phone’s calling functionality.
OK thanks!
I used Call Control Call Blocker for years and absolutely loved it until 2017 when I discovered that half the features I enjoyed were now only available to this who ‘purchased’ the upgrade. So, I went looking and found ‘Shoyld I Answer which at least gets the basic. I do miss not even having to hear the ring of bad calls. That’s now under ‘premium’ in CCCB. I am like others-I don’t want to be bothered by the ring and I don’t want them in my answering center. How do you compare SIAP to your #1 pick, Calls Blacklist by Vlad Lee? Thanks for your great help!
Hello @ginhunt:disqus, I have already suggested a call blocker app to Kerem Aydin in the comments below. The app name is “Call Blocker Free by NQ Mobile Security”. It’s #3 in the list above. This is one of the best call blocker apps and provides a feature that will silent all the blocked calls while that blacklisted caller will continue to hear the ring. The best thing is it’s completely free. 😉
Hi Mohammed. I need a call blocker with whitelist and also i want silent ring feauture when rejecting calls. Caller must hear endless calls. I want to see who called me in a seperate log. In my family time i used whitelist and at work time i check who called me. I want rejected calls just hear endless ring. Thank you:)
Hi, give a try to app #3 in the list above. The app name is “Call Blocker Free by NQ Mobile Security”. Once installed, go to Settings and there you will find “How to block calls” option. Tap on it and you will find 3 options to block calls:
1. Hang up,
2. Hang up and send a text,
3. Mute without hanging up.
You need to select the third option, which will silent the ring for all the blacklisted calls and the caller will continue to hear the ring.
Moreover, you will also have a separate log for all the blocked calls.
If you have any other question then please feel free to ask. 🙂
I’d like a call-blocker that allows to me block all calls not on my contact list, EXCEPT from a specific area code. I’ve already tried #1 and #3 on your list and I don’t see that feature. Any recommendations?
Hi @erinmcdade:disqus, I will recommend you to try “Blacklist Plus by Vlad Lee”. It’s #7 on the list above. It is a powerful calls blocker app for Android. The app allows you to create a custom Whitelist where you can add specific area code from where you want to receive calls. And then you can set the calls block mode to “All except whitelist”.
I hope this helps you out in accepting calls from certain areas only. Give it a try and let me know how it goes. 🙂
Thanks for the review. I have tried the #3 pick and now am trying an app called nights keeper but both give me the same problems. When I am talking on my phone and a second call comes in that is not in my contacts, I am disconnected from the call I am in and the offending call is also blocked. The other issue I have is, when my phone is connected to my car stereo via Bluetooth and a blocked call comes in my music will temporarily stop until the blocking software hangs up on the call. I really want an app that will give me the Apple iOS do not disturb style, if the number is not in the contacts it never makes to the phone, it goes directly to voicemail. Any suggestions. Thanks
Hi @markgoodine:disqus, thanks for stopping by! The call blocker app mentioned in #3 is a great choice for blocking all the calls that are not in your contacts. And the issue you mentioned should not happen. I have used call blocker on my phone and in case I receive any unwanted call that needs to be blocked, the app automatically puts the current call on hold, blocks the offending call, and then resumes the call.
To avoid unwanted music interruptions when your phone is connected via Bluetooth, you need to disable the call block notifications in the app settings.
I hope this helps. 🙂
I don’t want to block calls from unknown callers because it’s my business phone. But I want to be able to add calls to a blacklist or reject if I want to. Which is best for this? Or, do all allow a blacklist but let calls show up if you wish to connect?
Hi @TuckerdogNC:disqus, the majority of apps mentioned in this list have the exact same feature that you are looking for. Most will let you manually add numbers to the blacklist/calls reject list. Go for whichever app that suits your calls blocking style. If you want my suggestion then try “Calls Blacklist by Vlad Lee”. It is #1 on this list. 🙂
I used Safest Call Blocker which worked GREAT but it messed up my ringtone – that went to silent and I had to do a factory reset. So I am on the lookout for a simple app that will block any call that is not in my contact list – automatically to VM. What would you suggest?
I have an S6, Verizon, Android 7.0
That shouldn’t have happened. Call Blockers are designed to block calls only and should never interfere with ringtone. Anyways, the #1 app on the list i.e. Call Blacklist by Vlad Lee should be your best bet. It has an option called “Block Unknown Numbers” that allows you to block all numbers except contacts. Moreover, all the blocked numbers should be automatically forwarded to VoiceMail.
Give it a try and let me know how it worked for you 🙂
Why would anyone want spam calls going to voicemail? I don’t want the calls and don’t want them leaving messages that I have to delete.
if you are doing a project that involves contractors their subs will not be in your contact list, so better to go to voicemail.
I need a blocker that would not only reject the unwanted calls, but also not notify me of them – because frankly, I don’t need the notification, I don’t want to know the call happened at all. I get mostly spoofed numbers, so replying on a database of known numbers isn’t going to help. I’m desperate enough to want to block all calls except contacts, but this will put a big cramp in my job search.
Sure, tell us. We will be happy to add that to our list, if it is good enough.
@KittyDelAmour:disqus seems like you are looking for an app with aggressive call blocking abilities. I will suggest you to try Call Blocker by NetQin available here (already mentioned above in #03).
It has a ‘custom blocking mode’ option that allows you to accept calls from your contacts and whitelist only. Rest of the calls will be automatically blocked. And you can even disable the block notifications.
Give it a try and let us know what you think..
That app sucks. Read the reviews on it. The ads are worse than the spam calls.
Another worthy consideration is Should I Answer? Not sure if they have it for Apple, but that’s what I’ve used for a while on Android.
Thanks a lot for your suggestion! We will give that app a try and add it to our list if we find it useful in any way. 🙂
I have no anything useful yet. I want to make sure they can’t leave a voicemail. I want to simply hang up.
Hi @disqus_wF5r7EU6r8:disqus, if you simply want to hang up then any app should work for you. If you want my suggestion then download Call Blacklist by Vlad Lee. That’s what I use on my phone too.
I hope you find this useful 🙂
Hey @disqus_wF5r7EU6r8:disqus, a little heads-up. I have looked into your problem further and found an app called “Extreme Call Blocker” available here. It supports automatic pick-up and hangup feature that prevents the blocked caller from leaving a voicemail.
Maybe this is something you are looking for?
Hi @mohammadfarzanhussain:disqus I was Extreme Call Blocker’s biggest fan but it is no longer supported by the developer. It was the one app which had the ability to answer a call and disconnect it so that unwanted callers couldn’t leave voicemail. It was very easy to tweak ECB to work in conjunction with Truecaller and the stock phone app that came with my Samsung Galaxy S7. I am now receiving about 30 unwanted calls per day and I am no longer able to keep blocked callers from leaving me voicemail. I don’t want robocallers, bill collectors or former acquaintances to have the capability of getting inside my voice mailbox but apparently the ability to disconnect blocked calls stopped with subsequent Android system upgrades (I’m on Nougat now). Would you kindly let me know if you should hear any news of a redesigned app that keeps callers out of voicemail on Nougat or Oreo? Many thanks!
Hi @Natalie McDonald. Thanks for stopping by and sharing your query with us. You are right about Extreme Call Blocker being outdated. It was last updated during the end of May last year. It hurts when these one-of-a-kind Android apps with exclusive features are left outdated.
Anyways, I did some in-depth research on call blocking apps and tried some newly updated apps that offer what you are looking for i.e. blocking of calls by automatic pick-up and hang-up functionality. I found 2 apps but only first one will work on Nougat:
1. Should I Answer? by Mister Group s.r.o — I have tried this one. The app’s description page does not mention about blocked calls pickup and hangup feature, however, the functionality has been implemented but currently in a testing phase.
And please note that there is a possibility that it may not work on all Android phones. I have read somewhere that Samsung, on their new phones, has disabled the functionality required to make this feature work. But you can give it a try. The app is free.
2. Mr. Number by Hiya — This app has a hang-up functionality but it won’t work on Android 5.0 or later, as already mentioned in the description area. So don’t waste your time on trying this app. I tried but the option isn’t even visible in the app.
Go ahead and try the app “Should I Answer?” and then let me know if it helped you in keeping blocked callers from leaving a voicemail. 🙂
Hi Mohammad! I also spent several hours researching this after I left my original post and came to the same conclusion that Should I Answer was the best app to try. I had to do a lot of tweaking and rebooting on the first day and still an unwanted voicemail got through. The app’s settings menu also did not even offer me the “pick and hang” option it advertised. However, by the second day no voicemail messages were received from the one unwanted number that finally manages to get through after several attempts per day. But that was Sunday so maybe the call center agents weren’t trying as hard. Now it’s Monday and that will be the real test as I get about 30 unwanted calls on weekdays, more than weekends. I want to thank you for your prompt and courteous thorough response — let’s hope this works!
You are welcome, Natalie! Good to hear that you already found out about this great call blocking app on your own. I am glad you managed to set it up on your phone. The interface is a bit confusing as it has a lot of different options but you just need to set it once and then it will take care of your call blocking needs.
As far as telemarketers, spam calls, and robocalls are concerned, the blocking app has a crowd-sourced database of numbers where it stores all the reported numbers and automatically blocks them so you won’t need to add them manually. In case any number slips through and reach your voicemail then you can leave a rating for it to make sure it can’t reach you again.
Moreover, the app receives frequent updates. This means someone is there to listen and you can either leave a review or directly reach the developer if something does not work.
I hope this app continues to help you in blocking unwanted calls and makes your life easier 🙂
