[SOLVED] Samsung Can’t Hear Caller Unless On Speaker

Samsung is a popular brand but its devices still give people a hard time on occasions and Samsung can’t hear unless on speaker is a common complaint. Usually, if you struggle to hear the other person on a call, the in-call volume may be too low and you should increase it. Other solutions include restarting the device, getting into open space, booting into Safe Mode, performing a factory reset, running diagnostic, etc.

What Might Have Gone Wrong 

Low In-Call Volume

Generally speaking, if the in-call volume is too low, it’s only natural that you could barely make out what your contact is saying on a call. On the bright side, if the in-call volume is the root of the problem, there is no need to do much.

Bugs

All in all, it’s not uncommon for Android as well as Android apps to bug out all of a sudden. In most of the cases, Android bugs mess up many aspects of devices and volume is one of them. Hence, once it comes to Samsung can’t hear unless on speaker, you should give bugs some thought. Many bugs go away by themselves but others linger unless you take matters into your own hands. 

Poor Reception 

In layman’s terms, the strength of signal reception affects quite a few aspects of calls including volume. Unsurprisingly, in discussions about Samsung can’t hear unless on speaker, a lot of people report that the volume trouble occurs every time they have poor reception. 

Hardware Issues

As time passes by, all sorts of things would build up around the microphone of the device which eventually blocks out the sound. Aside from that, if you drop the phone from heights by mistake, hardware including the mic may be damaged. You should be able to deal with some of the hardware issues on your own. In the case that the issue exceeds your knowledge, it’s wise to contact the pros. 

Interference From Third-Party Software 

There is no doubt that third-party apps play a key role in shaping the phone experience of Android users. Still, it’s important to point out that software you install on your phone could complicate the function of the device. Unable to hear your contact unless you put the call on speaker? Then you should add interference from third-party software to your list of suspects.

Approaches To The Situation 

Increase In-Call Volume  

  • Step 1: Use another phone to call your phone.
  • Step 2: When the incoming call notification surfaces on your phone, accept it. 
  • Step 3: Press the home button to go back to the home screen then hit the Volume Up key to increase the in-call volume. 

Restart 

  • Step 1: On home screen, swipe down from top to bottom twice. 
  • Step 2: Click the Power icon and pick Restart 
  • Step 3: When the scream comes back on, determine whether the issue persists. 

Get Into Open Space

It’s possible to increase the strength of signal reception in many ways but the easiest is to get to open space. As the number of obstacles in your surroundings decreases, the strength of signal reception increases accordingly. Once the signal reception is strong enough, you would be able to hear your contact loud and clear. 

Boot Into Safe Mode

  • Step 1: On home screen, swipe down from top to bottom twice. 
  • Step 2: Click the Power icon, press and hold Power off then pick Safe Mode.
