How to turn on speakerphone on Xiaomi Redmi 8

Xiaomi smartphone owners often face the need to put a conversation into hands-free mode, whether to talk to colleagues or watch videos in a noisy place.The Redmi 8 model, despite its budget, features a quality multimedia speaker that is able to deliver great sound when set up correctly. However, the standard MIUI shell interface sometimes hides some useful features or doesn't work as users expect.

In this article, we will take a look at all the ways you can activate loud sound on your device, and we will look at the standard methods of switching during a call, multimedia audio settings, and hidden engineering menus. Understanding how audio works on a MIUI-based Android system will allow you to control sound more efficiently.

Special attention will be paid to eliminating typical issues where the power button doesn't work or the sound remains quiet even at maximum volume.On Redmi 8, the volume of the call and the media are adjusted independently, which often causes confusion for new users.

Basic ways to activate during a conversation

The easiest and most obvious way to switch to speaker on Xiaomi Redmi 8 is to use the phonebook interface during an active connection. As soon as you make a call or receive an incoming call, a conversation control panel appears on the screen, and there's a button with the speaker image, which is the Hands-free mode switch.

Press this button once to activate a loud sound. The indicator will change color, usually turning green or blue, which signals the transition to hands-free mode. If you press the button again, the sound will return to the conversational speaker located at the top of the screen. It is important not to confuse this mode with a Bluetooth headset that can be connected to the device.

In some cases, the button may be inactive or missing, which happens if the smartphone detects the connection of a wired headset or Bluetooth device. In this situation, the system automatically redirects the audio stream to an external accessory. Disable the extra devices to unlock the possibility of using the built-in speakerphone.

  • πŸ“ž Click on the speaker icon on the call screen for instant turn on.
  • πŸ”Š Make sure the volume sliders are raised to maximum during the conversation.
  • 🚫 Turn off Bluetooth headphones if the hands-free button doesn’t respond.
  • πŸ“± Use a proximity sensor to make the screen go off when you lift it to your ear, but the sound remains loud.

MIUI interfaces may vary depending on the firmware version, but the logic remains the same: If the standard method fails, it may be a software failure or a dynamic membrane damage, so it's worth checking the audio settings in the main menu.

System volume and multimedia setting

Users often confuse the volume of the call with the volume of the media. On Redmi 8, these parameters are separated by software. To make sure your speaker is running at full power, you need to check the sound settings in the system menu. Go to Settings β†’ Sound and vibration.

Here you'll see a few sliders that are responsible for different types of audio: the Call slider regulates the volume of incoming calls and alarm clocks, and the Media adjusts the sound in apps, games and videos. For hands-free mode, it's critical that both settings be twisted to maximum, and sometimes after updating the system, the settings can reset.

Use side volume buttons while playing video to quickly adjust the multimedia channel, not the volume of the call.

Also available on this menu is the "Sound Improvement" feature, which on some firmware versions may include an equalizer or a "Mi Sound" mode, and enabling these options can significantly change the timbre of your voice to make it sound more loud or bass-like. Experiment with settings to find a balance between volume and quality.

  • 🎚️ Check individual call and media sliders in the settings menu.
  • 🎧 Turn off the Mi Sound effect if the sound becomes distorted or wheezing.
  • πŸ”” Make sure the Do Not Disturb mode does not block audio notifications.
  • πŸ†™ Use the physical control buttons for quick adjustment.

Remember that the maximum volume at the software level is limited by the manufacturer to protect your hearing and speakers.Trying to get around these limitations with third-party apps can cause audio components to fail.Take care of your Xiaomi from overload.

Engineering menu and boosting dynamics

For advanced users of Xiaomi Redmi 8, you can adjust the sensitivity of the microphone and the power output of the speaker through the engineering menu. This is a hidden part of the system designed to test equipment. Be careful: changing unknown parameters can disrupt the phone.

To enter the engineering menu, open the Phone app and type in a special code. Enter ##3646633#. Once you enter the last star, the EngineerMode menu will open. Go to the Hardware Testing tab, then select Audio. Here you can adjust the volume levels for different use cases.

Risks of changing settings in EngineerMode
Incorrectly configuring Audio settings in the engineering menu can cause the speakers to be damaged or no sound at all. Always write down the initial values before changing.

In LoudSpeaker Mode, you can see the volume settings (Level 0-15). Increasing the values here can make the sound louder than standard, but it carries risks. Android on Redmi 8 has program limits that can not always be bypassed even here without root rights.

After making changes, be sure to press the Set button to save settings.Reboot device is not required, changes take effect immediately. If the sound becomes distorted, return the default values using the Default button in the same menu.

πŸ“Š Do you use an engineering menu to customize the sound?
Yeah, all the time.

I'm afraid to break something.

Using third-party applications to enhance

If regular funds are not enough, Google Play apps come to the rescue. There are many equalizers and amplifiers that can programmatically boost the signal passing through a smartphone audio chip. Popular examples include the Volume Booster GOODEV or Precise Volume.

The way these apps work is to add extra (amplification) to the audio stream, which can go up to 20 percent, 40 percent, and even 60 percent above the standard high, but it's worth remembering that Redmi 8 has a modest speaker by modern standards, and over-boosting will lead to wheezing.

When you install these applications, the system will ask permission to change the system's audio settings, which is necessary for proper operation. Don't give applications excessive rights, such as access to contacts or geolocation, unless it is necessary for their functionality. Data security is also important.

  • πŸ“² Download the verified volume booster from the official store.
  • ⚠️ Do not turn the gain 100% so as not to burn the speaker.
  • 🎚️ Use preset profiles (Music, Movie, Voice).
  • πŸ”‹ Watch the battery charge as loud sound consumes it faster.

Some apps require root rights for deep integration. On Xiaomi, superuser rights are possible, but that would take away your warranty and could disrupt banking applications. For most users, the capabilities of conventional apps without root are sufficient.

Solving problems with quiet sound and wheezing

When the speakerphone on the Xiaomi Redmi 8 is quiet or distorted, it can be caused not only by software settings, but also by physical factors: Dust, pile of pockets and moisture are the main enemies of smartphone acoustic systems. The speaker grid is clogged over time, which silences the sound.

Use a soft toothbrush or dry brush to clean the device, walk carefully through the speaker hole on the bottom end of the device, and avoid sharp objects such as needles or pins, as they can easily damage the speaker membrane or push dirt even deeper.

⚠️ Warning: Never use alcohol or aggressive cleaning fluids to wipe the speaker mesh.The liquid can penetrate and cause contact corrosion, leading to a complete failure of the audio module.

If the cleaning didn't work, the problem could be a software conflict: Try rebooting your phone to Safe Mode, press the off button and then the Turn off icon on the screen, and if the sound is normal in Safe Mode, some app you installed is interfering with the audio.

Done: 0 / 4

In rare cases, a quiet sound indicates a fault in the plume or the speaker itself, especially if the phone fell or fell in the rain, in which case the software methods are powerless, and you will need to replace the hardware components in the service center.

FAQ: Frequently Asked Questions

Why is Redmi 8 silent on WhatsApp on speakerphone?
WhatsApp uses its own audio compression algorithm, which can conflict with MIUI settings. Try to turn up the volume while listening to a voice message, and check the equalizer settings in the messenger itself, if available.
Can you make the sound louder through ADB?
Yeah, it's possible, by connecting the phone to a PC with debugging enabled. USB, You can enter the command adb shell settings put global volume_steps_speaker 30 (However, on newer versions of Android and MIUI This method is often blocked or requires root permissions to modify system files.
The phone only works when the phone is on the table, why?
This could be due to the proximity sensor or the accelerometer, and some shells automatically turn down the volume when you pick up your phone, thinking you're moving it to your ear, check the sensor settings in the engineering menu, or turn off the smart gesture control features.
Does the case affect the volume of the Redmi 8 speaker?
Yes, a tight silicone or leather case can block the speaker's output or create a resonating camera to degrade the sound. Remove the case and check the volume. If the sound is better, consider buying a case with a more accurate perforation under the speaker.
