How to increase the sound on an Android phone when calling: a complete guide

Are you missing important calls due to low sound on your smartphone? The problem of low volume during incoming calls is familiar to many owners of Androiddevices - especially on budget models or after system updates. The reasons may lie in the hardware limitations of the speaker, erroneous sound profile settings, or even software failures.

In this article we will analyze all possible ways to increase the volume of the call from basic settings to hidden functions of the engineering menu and specialized applications. You'll learn how to bypass manufacturer limitations, test speaker health, and even physically improve your audio experience. The material is relevant for devices on Android 8.0–14 (including Samsung One UI, MIUI, ColorOS and other shells).

Before proceeding with the settings, make sure that the problem is not related to mechanical damage -check that the speaker is not closed case or protective film, and try cleaning the headphone jack (if the sound disappears when you connect the headset).

1. Basic volume settings in Android

Start with the obvious - checking the standard volume controls. What many users miss is that ring and notification sounds are adjusted separately from media sound. To change the volume: Press the physical button on the side of the phone during an incoming call (not after!). A slider with a bell icon will appear on the screen. Android The sound of calls and notifications is regulated separately from media sound.

To change the volume:

• 📱Press the physical button volume on the side panel of the phone during an incoming call (not after!). A slider with a bell icon will appear on the screen.
• 🔊 Go to Settings → Sound → Volume and manually adjust the slider "Ring" (sometimes it is combined with “Notifications”).
• 🎵 Make sure the mode is on "Sound" (and not "Vibration" or "Silent") - check the switch in the notification shade.

On some devices (for example, Xiaomi or Realme) there is a separate option Headphone volume —if you are using a headset, it is also worth checking. Also pay attention to sound profiles: in Samsung this Modes and routines, in Huawei — Smart assistant.

2. Engineering menu: hidden volume settings

If standard controls do not provide a sufficient volume level, you can turn to engineering menu the hidden part of the system where the factory settings are stored. Caution: incorrect changes here can lead to failures!

Instructions for most devices:

1. Open the application Phone and enter the combination:

   ##36446337##

   (for Mediatek) or

   ##4636##

   (universal code).
2. Go to section Hardware Testing → Audio (names may vary).
3. Select LoudSpeaker Mode or Ring and manually increase the values Max Vol (maximum volume) by 5-10 units.
4. Save the changes and restart the phone.

For processors Qualcomm Snapdragon use the code

##8080##

then select Hardware Test → Audio → Loud Speaker. On some models Samsung The engineering menu is locked - in this case, only root access or third-party applications will help.

3. Sound amplification applications

If manual settings do not help, use specialized utilities. They work on two principles: either amplify the signal at the software level, or bypass system limitations.

Top 5 proven applications:

• 🔊 Volume Booster GOODEV - a simple booster with preliminary profiles for calls, music and notifications. Supports Android 5.0+.
• 🎧 Precise Volume —allows you to fine-tune the volume in 1% increments, including system sounds.
• 🛠️ SoundAssistant (from Samsung, but works on other brands)—advanced management of sound profiles.
• 📱 Equalizer FX —enables an equalizer for calls (requires root on some devices).
• 🔕 HearBoost - enhances high frequencies, useful for people with hearing impairments.

Install one of the applications (for example, Volume Booster) and follow the instructions:

1. Open the application and provide access to settings sound.
2. Select the sound type - Ring Volume (call).
3. Move the slider 10-30% above the standard maximum.
4. Activate the option Boost and test sound.

⚠️ Attention: long-term use of boosters at maximum settings can lead to overheating of the speaker or sound distortion. We recommend increasing the volume gradually, testing the quality after each step.

4. Replacing the ringtone with a louder one

Sometimes the problem lies not in the volume settings, but in the melody itself. Standard ringtones Android are often optimized for a “pleasant” sound, rather than for maximum audibility. The solution is to set a special melody with enhanced high frequencies.

How to choose the optimal ringtone:

• 🔍 Use melodies with a frequency 2000–4000 Hz —they are better perceived by the human ear at a distance.
• 🎵 Download ringtones from categories "Loud" or "Alert" in applications like Zedge or Ringtone Maker.
• 📢 Check the duration: short signals (1-2 seconds) are repeated more often and attract attention.
• 🎧 Create your own melody in Audacity, increasing the volume by 6-10 dB and adding compression.

To set a custom ringtone:

1. Place the audio file (format .mp3 or .ogg) to the folder Ringtones on the internal memory.
2. Go to Settings → Sound → Ringtone.
3. Select your file from the list (if it is not there, restart your phone).

For devices Samsung with One UI you may need to use the application My Files to transfer the file to folder Media → Audio → Ringtones.

Why do some melodies sound quieter than others?

Sound files have different amplitudes and frequency ranges. For example, bass melodies (low frequencies) seem quieter when played through a small phone speaker, while high frequencies (ringing signals) cut through noise better.

5. Checking the speaker and hardware solutions

If software methods do not produce results, the problem may be physical malfunction of the speaker or a clogged connector. Diagnose:

Symptom	Possible cause	Solution
The sound is quiet only when calling, in music normal	Failure in the sound profile or manufacturer limitation	Reset the sound settings or use a booster
The sound is distorted (wheezing, crackling)	Damage to the speaker or membrane	Contact the service center
The sound disappears when you tilt the phone	Poor contact of the speaker cable	Disassemble the phone and check the connection
Quiet sound in the headphones	The 3.5 mm or USB-C connector is dirty	Clean the connector with alcohol and a needle

To clean the speaker:

1. Turn off the phone.
2. Use a soft brush or compressed air (can) to remove dust from the speaker grille.
3. For stubborn dirt, carefully blot the grille with a cotton swab dipped in isopropyl alcohol.

⚠️ Attention: do not use sharp objects for cleaning - this may damage the speaker membrane. If after cleaning the sound does not improve, the speaker probably needs to be replaced (repair cost - from 800 to 2500 rubles depending on the model).

6. Settings for Hearing Impaired Users

If you have difficulty hearing incoming calls, there are special accessibility features that may help: Android There are special accessibility features that can help:

• 🔔 Notifications with flash: turn on in Settings → Special. features → Hearing → Notification flash. The camera will flash when there is a call.
• 📳 Vibrate with custom rhythm: in Settings → Sound → Vibrate when call select a long or repeating pattern.
• 🔊 Headphone audio boost: activate Special features → Hearing → Audio boost (available on Android 9+).
• 📱 Reassigning buttons: assign to a button power call answering function (in Special features → Convenience).

For devices Samsung there is an additional option "Notifications on the lock screen" - it displays an enlarged name caller and answer button. To enable:

1. Go to Settings → Lock screen → Notifications.
2. Select Show content.
3. Activate the option Increased call notifications.

Also consider purchasing external speaker with Bluetooth (for example, JBL Clip or Xiaomi Mi Portable Speaker) - you can attach to clothing and use as a speakerphone.

7. Alternative methods: from root access to external devices

If none of the above methods work, radical solutions remain. They require more effort, but give maximum results.

Methods for advanced users:

• 🔧 Root access + Xposed Framework: module Xposed VolumeSteps+ allows you to fine-tune volume steps and remove restrictions.
• 📱 Custom ROM firmware: some firmware (for example, LineageOS) have advanced sound settings.
• 🔊 Connecting an external amplifier: via USB-C or Bluetooth (for example, FiiO BTR3K).
• 🛠️ Replacing the speaker with a more powerful one: suitable for models with a removable back cover (for example, Samsung Galaxy M or Xiaomi Redmi Note).

To obtain root-rights, follow the instructions for your model on the forum XDA Developers or use utilities like Magisk. Remember that this will void the warranty and may cause your device to fail. "briku" devices.

If you are not willing to take the risk, consider purchasing smart watches (for example, Amazfit GTR or Samsung Galaxy Watch) - they duplicate call notifications with vibration and sound signal.

8. Common mistakes and how to avoid them

When trying to increase the call volume, users often make mistakes that aggravate the problem. Here's what not to do:

• 🚫 Setting the volume to maximum in the engineering menu without testing - this can burn the speaker.
• 🚫 Using uncertified firmware from unknown sources - the risk of infecting the phone with viruses.
• 🚫 Clean the speaker with wet wipes or aggressive solutions (acetone, gasoline).
• 🚫 Turn off system sounds through ADB without knowing the commands - this can lead to interface failure.

Also avoid:

• 🔋 Battery discharge below 20% when testing sound - low charge can affect power dynamics.
• 📵 Using the phone in places with strong humidity (bathroom, swimming pool) - this shortens the life of the speaker.
• 🔊 Listening to music for a long time at maximum volume - this "tires" the speaker and reduces its sensitivity.

If after all the manipulations the sound remains quiet, check the phone for presence viruses (some malware blocks the sound of the call) or contact a service center to diagnose the hardware.

FAQ: Answers to frequently asked questions

🔊 Why did the ringer sound become quieter after updating Android?
