Among the distinctive qualities of Samsung phones are a bright screen, ergonomic key layout, and an exceptionally elegant design. Unfortunately, along with this, we can also highlight the main disadvantage - most devices have a quiet sounding speaker. In order to add volume to it, you need to perform a number of simple steps.
Instructions
To safely increase the signal volume, you must increase the volume of the source track. Increase volume by changing engineering settings The phone's firmware can damage the speaker. This can happen due to the fact that the speaker is set to the volume that was originally programmed into the firmware, so increasing it too much can ruin it.
The best option for editing the melody would be Adobe program Audition or Sony Sound Forge. These programs have sufficiently high functionality to fully process a track, both in terms of increasing the volume and in adapting the melody for the phone speaker.
Install and launch the audio editor. Open the track you need using the "File" menu or by dragging it into the program work area. Wait for the track to load. To save space on your phone, it is advisable to first trim the track and then edit its volume. Select the "extra" areas of the track and delete them.
Select the resulting melody. Using the “Volume Boost” effect, gradually increase the volume of the track, simultaneously testing for euphony. You can also use the “Normalize” effect; these effects are similar in the result that is obtained after processing. Once you are sure you have reached the euphony limit, apply the changes.
Use the Graphic Equalizer effect. This is necessary because the speaker cell phone designed to reproduce high and mid frequencies rather than low frequencies. Reduce the strength of the low frequencies, leaving the highs and mids at the same level as they were. Copy the track to your phone's memory and test it. If it is too loud and the speaker cannot reproduce it properly, correct it using an audio editor.
Not all smartphones have speaker quality or volume levels that will make you envy your device's stereo effect. These two points - along with poor speaker placement - are the biggest factors that prevent you from enjoying the sounds coming from your smartphone. Below we publish a selection of tips on how to improve sound quality and increase volume on Android.

Check your settings
You can optimize the audio experience on your Android device using the appropriate settings. Note that not all user interfaces have them, so not every user will be able to use them. If your device has them, then the situation becomes simpler. After you have dealt with them at least once, in the future you can easily and simply use them again to assign new sound parameters. For TouchWiz interface, for example, you need to open the “Settings” section and select the “Sound” category. Here you will need to click on “Sound Settings” and set the most optimal values to improve the sound.
MIUI interface developed by Xiaomi has a headphone amplifier. You just need to turn it on and select the type of headphones you are using - internal or external.
Sony's Xperia UI, which has an equalizer, will give you the option to use the ClearAudio option, which can be found in Settings. HTC's proprietary Sense interface includes a BoomSound option, without which the sound quality will be mediocre. We will also add that in interfaces such as Oxygen, Optimus or just stock Android, you will not have the opportunity to optimize audio settings.
Install a better audio app
You have the opportunity to replace any stock music application with one that has large quantity sound controls. We recommend turning your attention to Poweramp or Equalizer+. Both of these apps include various audio settings, presets, bass adjustments, and more. In addition, Equalizer+ contains a 5-band equalizer, and Poweramp has a 10-band equalizer for more fine tuning. To get even more out of these apps, you'll need to purchase their paid versions, but if you do, you won't want to go back to their free options.
Use an equalizer
Default audio controls except Sony smartphones and OnePlus 2 models are not ideal. Some of them have a basic equalizer, although this often only works with the default music application and does not affect the control of audio played back by a non-music player. Therefore, we advise you to look into Play Store and choose a decent equalizer app like Music Volume EQ and Bass Booster.
Find out the location of the speaker
This may sound a little basic, but the first thing you need to do is figure out where the speaker is located on your device. Many smartphone models have two speaker grilles, although in reality only one of them produces sound. If your speaker is blocked for some reason, then the sound quality will be low or there will be no sound at all. In general, determine from which places on your device the sound comes from - to do this, simply play a melody and cover different slots of the smartphone with your fingers. Ideally, there shouldn’t be many places where the sound comes from, other than the speaker itself, and after you find them, you can look for ways to fix the identified problem.
By knowing exactly whether your device's speakers are front-firing, bottom-firing, or rear-facing, you'll be able to make the smartest decisions about how to hold the device for the best sound quality. Our advice to you is that you should not cover the speakers with your palm or fingers when you hold the smartphone in your hand (by the way, this is the most common situation when users run games on devices with bottom-mounted speakers), and try to make the speakers look at you and not away from you. you.

Check if the case is covering the speaker
If your smartphone is wrapped in a protective case, then this accessory may affect the sound quality. All those vibrations emanating from inside the device can be muffled by an additional layer of plastic or rubber, which the manufacturer did not take into account when developing its speaker system. In addition, not all case manufacturers also take into account the design features of your device. Some cases may cover important parts of the device, such as the audio jack, microphone, or speaker. Remember that before you buy a case, you need to check that its components are not blocking any major areas of your smartphone.
Use headphones
We've found from our own experience that most smartphone speakers have average sound quality, even when using a music app or equalizer. One of the best exits In this situation, using a good pair of headphones will be helpful (note that some audio settings in your device will not work at all unless headphones are connected).
Turn up the volume
If you have root rights, then you are given the opportunity to bypass the restrictions maximum level Android OS volume in just a few steps. If you don’t want to give your device root rights or are simply not sure about the effectiveness of the volume-increasing applications available in the Play Store, then you will have a number of additional things in stock.
Try this experiment involving sound waves: bring your smartphone to the corner of the room so that its speakers are facing it, and turn up the volume. You will hear a louder, bassier reverberation compared to the center of the room. The same principle applies to any object: place your device in a box, in an empty glass, or in front of a bowl (pan), and you will be surprised at how much louder your device's speaker will sound.

Samsung wave is a very good and productive phone based on the Bada operating system. In principle, the phone pleases with its appearance and its characteristics, but, like any phone in this category, it has its drawbacks, which are mainly related to the operating system. Since this operating system Although it is still quite new, it has its own shortcomings. One of these shortcomings is the weak speaker volume. This problem, in principle, can be easily corrected with your own hands, but sometimes there are situations when it is necessary to resort to hardware solution malfunctions.
There are two main ways to solve this problem: software and hardware.
A software way to change the speaker sound level.
Remember that you perform all the following actions at your own peril and risk, and incorrect actions on your part can lead to negative consequences. Before turning up the volume, consider whether you really need it.
- Type on your phone keypad service code, which will allow you to go to the additional phone menu: *#197328640#.
- Next, a window will appear in which 8 phone settings items will be displayed. Since we need sound settings, we select item No. 5 accordingly.
- In the audio menu that opens, we select the 2nd item: AP Volume Config.
- The screen will display a menu of various settings: RCV Config – setting the speaker that is used during the conversation; EAR Config – adjust the headphone volume; SPK Config – setting the volume of the speaker that is used for speakerphone and sound playback; BTH Config – adjust the volume in the Bluetooth headset. Since we are interested in point No. 1, we select it. In the window that appears, you can also configure various parameters of this speaker, but remember the consequences.
- Since we are interested in the volume during a conversation, we select item No. 7: Voice Call volume.
- In the new window we select last point No. 6. The image on the display will be updated, and the inscription at the top of the display will change from , READ, to the opposite, WRITE. This action provides customization options.
- At the bottom of the screen there will be a line in which you need to enter a number, but not more than 75. This parameter is determined for each in its own way by practically changing it, so try it.
- Then, when you press the "OK" button, the image will update and you will see that the value has changed.
- After this, you exit the service menu and reboot your phone. The value changes, but if you want to set a new volume value, then all of the above steps will have to be repeated in the same sequence.
A hardware way to change the speaker sound level.
This can only be done by replacing the speaker, or adding a 5 kOhm resistor to the sound amplification circuit. This method is suitable for people who understand this and will be able to carry out the process of adding a new element to the circuit themselves, and for those who do not understand this, it is better to leave everything as is, or try the method described above.
All the methods described are very effective, but if done incorrectly, they can lead to irreversible consequences. If suddenly this happens, you will have to contact service center for phone repair.
