Boosting Volume

Depending on what device you have, there may be an equalizer in the sound settings. If there is you can turn all the levels up an equal amount, which will increase the overall volume without changing the sound. Note that pushing the volume up this way might exceed the limits of the speaker and cause some distortion.

 

what phone do you have? i do not think there is an app that can boost volume. usually something like that is not a software issue, but a hardware one. is the volume low on every use? like in an app like youtube vs call volume? is it low for both? if so, it could be just your phone......like i said a hardware issue.

 

As was mentioned below, EQ standalone apps are available. Also, and I know this from Huawei experience, it may be as simple as your case covering the speakers.

I recommend version 2.03 for an ad-free experience, if it will work on your device.

If it won't work, then try the newest version.

Keep in mind that Android only allows one sound enhancement app to work at a time, and if you try to activate multiples then you can jam it up to where none of them will work.
So be sure to force stop any other user installed sonic apps on the device.

If it still wont work, try restarting the device and try again.

This will reset the 'jam' if there is one.

 

It is, but you will get ads.

UpToDown is the number 2 appstore in the world.

Just so you know, Google PlayStore has more apps with malware than any other.

I gave you the UpToDown link, so that you can try the older, ad-free version to see if it works on your phone.

It is an old version, so if your device is newer, it may not work unless you use the new version of the app.

UpToDown allows the downloading of older versions of apps, whereas Google does not.
I don't like Google deciding what I have available to place onto my devices.

 

I have Equalizer FX Pro, which I don't really use anymore since I bought Pi player which also has one as many players do. FX Pro does have "bass boost" and "loudness enhancer" options, not sure if that'll get you where you want to go.

 

My phone is not rooted

 

I'm not sure about the free version, and this is not meant as a dis, but please shake off the paradigm of two buck stuff being a big deal, a burger at md's costs more. I've paid for lots of stuff that I don't even use anymore, and the authors would probably rather have the ad money anyway.

 

UpToDown is not an app that you will find on the PlayStore.

UpToDown is another appstore altogether.

It is the second largest in the world.

Speakerboost is available from PlayStore, but not in an older, ad-free version.

I don't like dealing with PlayStore, partly for this reason.

Another app that may help you is EQ-FX.

Then you should try again after restarting your device.

Remember that Android will only successfully run one sound enhancement app at a time.

And there is usually one that is built in, regardless if it is accessible by the user.

Restarting the device will make sure that no other sound effects are running.

After the restart, try it again.

Keep in mind that this will not work if you are trying to play music and your music player has sound enhancements- EQ, virtuallizer, bass boost, etc.

It also most likely will have no effect on phone call volume.

 

Ok, so do the restart, then see if the app works.
