5 Best free spam blocker app for android in 2023

How do you feel when someone is spam calling you? Do you want Spam Blockers for your Android Mobile Phone? Well, then you should read this blog. 

Earlier, I had been searching for one such app. I used to receive plenty of phone calls almost daily. No, not from friends or relatives, but from telemarketers and fraudsters. They used to tell me that “I won flight tickets free of cost”, or pretending to be the Internal Revenue Services and threatening to arrest me, if I don’t pay up.

They never ceased to annoy me when they made those spam phone calls. That’s when it occurred to me that for my Android phone, I should have installed an spam call blocker.

After that I researched a bit and found some of the top spam blocker app for android which I will share in this blog-

05. Call Control-

What is the reason that I get all these spam calls?

Well, there is a high chance that you are receiving spam calls because somebody has your phone number. It could be that you mistakenly put your number on some malicious website or one of the companies sold out on you. If you’re still wondering, “Why such random callers call me?” Well then you should read this:

  • You have put your personal number on some un-trusted website
  • Your phone number was made public through the data leak.
  • Unknowingly, you sent personal information about yourself to a cybercriminal who deceived you
  •  Someone dialed your number randomly
  • In the past, you picked up an unknown caller

It’s justified to claim that fraudsters try out unspecified telephone lines for immoral practices. Occasionally, they purchase figures of corporations like those you have used before. Alternatively, fraudsters may collect these numbers after breaking into a data facility. That’s how it starts. However, the torrent begins after you receive a single scam call or accidentally give away yours numbers to a con man

My Recommendation

Out of all these apps, true caller is probably the most popular one, even if it has many premium options that require payment. It would even be the greatest at its work, sufficient and even beyond that which an ordinary user desires. Therefore, since this app comes with almost all of the available features for free-plus something extra over call blocker, we suggest use this app.


Spam calls are annoying and interrupt us in our day-to-day activities, and also violate our privacy. Fortunately, many applications have been developed in order to address such kind of problems; these applications come with numerous features such as spam detection, the capacity to reveal caller identity during a phone call, call blocking and others. Get these apps if you’re seeking a quitter and quieter cellular experience. The ultimate solution to robocalls and spam calls is using a good robocall blocker app that includes huge regional database of callers for detecting, analyzing, and rejecting a spam/scam call before it rings on your mobile. In this case, choosing genuine caller is non-proffice. Presently I use truecaller app and believe me I am no more worried about spam calls.
