Best Ways to Improve Android Call Quality

These days it is hard to notice that smartphones are also phones that can be used to make calls. Thankfully, the smartphone manufacturers are bringing their A game when it comes to call making hardware inside their phones. While the call quality has vastly improved when compared to phones of the past decade, there is still some ways to improve Android call quality.

Most smartphones these days come with top-of-the-line your PCs as well as multiple mics to make your calling experience exceptional. Unfortunately, the call quality is not only limited to the hardware inside your smartphone but there are other factors that may affect it negatively. This article is going to talk about how Android call quality can be improved further by eliminating the external elements that affect it adversely.

1. The Ear Piece

One of the most important aspects of receiving a call is the ear piece, over the years smartphone manufacturers have improved this by using durable materials and even introducing water resistance. Some smartphones have opted additional measures to improve Android call quality. Xiaomi Mi Mix came with a tissue conduction vibrating screen and didn’t even have an earpiece at all. HTC uses the front facing stereo speaker to give your call quality a bit of an oomph.

  • If you are using the same smartphone over the years and you have noticed a gradual decrease in its quality, there is a high chance that dirt and grime has accumulated in the ear piece. I recommend that you closely observe it and see if there is any residue inside it. If it’s easy, try to use a small pin to clear the earpiece cavity. If it’s a bit harder, you’ll have to take it to a professional to have it cleaned.
  • If you have a screen protector on and it’s misplaced on the screen, the earpiece may have been partially obscured. This means you’ll hear less sound coming out of the earpiece because the protector is covering it. So, make sure that you only apply front screen protectors that are made for your smartphone model. Otherwise, there’s a high chance that the earpiece will have trouble emitting sound clearly.
  • Some sturdy cases also tend to cover the front parts of the smartphone to better protect the hardware. While this is a great way to avoid any damages to your smart phone, it will also increase the space between your ear and the earpiece. If you’re having trouble hearing the other person, I recommend removing the case and seeing if the problem goes away.

2. The Microphone

The call quality doesn’t mean you are hearing the other person clearly, it also means that the other person can hear you loud and clear as well. A conversation can only take place if both parties can be heard clearly. Many smartphone manufacturers are making improvements to the mics included in their smartphones and some also include multiple mics to reduce noise and amplify voice.

  • Just like the earpiece, the mic is also a physical hole, so make sure it’s not completely filled with tissue paper residue that has accommodated over time in it. Cleaning the mic hole may prove to be tricky because the mic holes are generally very small. Take a flashlight and see if there is something stuck in it and by using a small needle, try to get it out but don’t try too hard yourself. If you can easily identify that it’s blocked, take your smartphone to a professional and they can clean it in a very short time.
  • If you have a case or cover for the smartphone that is not manufactured exactly for your particular model, then the mic might be blocked by it. This usually happens when you purchase a third-party case for your smartphone that is not up to par with the standards. So, receive a few calls after removing the cover and see if it makes any difference.

3. Interference

When you make a call on your smartphone, you talk into the mic, the mic turns it into an electrical signal, which is then changed into radio waves and broadcasted. Then the tower picks up your signal and send another signal to the receiving end. This is an incredibly impressive process that happens in mere fraction of a second. So, naturally there are external elements that can reduce the Android call quality by affecting the signals.

  • Smartphones have bad reception when you are in a basement. This is because the radio waves have a hard time penetrating walls and ceilings. The lower the frequency, the better they will be at penetrating obstacles but they will have a hard time reaching underground. So, make sure you are outside when making a call or at least on the ground floor.
  • Strong electrical equipment can also make the sound quality bad. Same goes for machinery that generates a magnetic field. This is highly uncommon though, if you are in a normal location that doesn’t have these machines, you’ll have no problem receiving a call.

4. Bad Coverage

One of the most common reasons why call quality suffers is the network coverage. If your network is not fully covering an area, or the tower placements is a bit off, you’ll have patches of land where cell phone reception is really bad. So, make sure that you get a network that covers your area perfectly. For example, in my country one network works really well on the highway while others don’t fare so well. So, make sure that your area is fully covered by the network before committing to it.

5. Use Hands free

This is a very simple solution to improve Android call quality without having to spend a lot of time and resources. You know they say 2 heads are better than one but here 2 ears are better than one. Every smartphone comes with a hands-free so you are at least covered there but if you want, there are some other great hands-free for Android available at reasonable prices. Using both ears to listen to a call will have a positive impact on your calling experience.


These are some ways to improve Android call quality and they have been proven by many people in field. While they may not drastically improve Android call quality, they will certainly make the experience a lot better. Whenever I feel that the call quality is dropping, I tend to change my position in a room or even go outside and the problem usually goes away. However, I personally think that Android call quality is already near perfect these days and I have no qualms that it will only improve from here.

Do tell us your Android calling experiences and tell us how you feel modern smartphones are better than the phones from yesteryear.
