There are not few users who encounter this situation. And in many cases, it is something spontaneous. The mobile speaker stops working, and has had no fall nor has he received any blows. What can be done in these cases?
It is essential that this happens in the background, which is why it is recommended that this does not always happen. The audio from my mobile is not working, what can I do? In this case, there are quite a few things that you have to do if you need to make a change, which in the end is important to say the least.
1.- Identify if it is the speaker
Firstly, identifies that the problem comes from the speaker. To do this, connect a pair of headphones and see if you can hear sound through them. If so, then the problem has to do with the speaker and not with all the audio from the mobile.
2.- Have you turned up the volume?
It seems logical and obvious, but have you raised the volume of the mobile? On Android, there are multiple "volumes" so to speak. There is the audio of calls, the audio of multimedia, and the audio of alarms. It may be that by modifying one of these volumes you have not modified the other. For example, when you are playing a game, if you turn the volume up or down, you are only changing the media volume. So, press the volume up or down button, and see if a settings option appears to the right of the volume bar. If so, click on that option, and you will see how several volume bars appear that correspond to the other volumes we are talking about. If it is not the case, go to Settings> Sound, and here you will have these options. Just notice that you don't have the volume down.
Check the car handsfree
It is one of the things that you can do, especially if you have not done it before. If you have activated the car handsfree and you have decided to remove it, try to continue moving forward. If you have activated it by default, the important thing is that you check it and remove it, which is the main basis in this regard.
It is nothing new that this happens when connecting Bluetooth, if you have not allowed it, you can do this and make a big change, which is what you are looking for in the end. The handsfree used in the car will activate this and it will not be heard on the mobile phone, which is something that becomes essential in this regard.
If you need to disable this, go to your device settings and remove Bluetooth so as not to send what is happening at that precise moment. It is recommended that the user can do such things, such as deactivate the thing, which is a detail to be considered by you and also by other users.
Be careful with the apps you install
If you have installed any application and it has caused all this, what happens to be recommended is that you uninstall the app and it has the opposite effect. Among the things it becomes important that you have to look for the last one installed one by one, delete this is one of the things you should do, from settings and then entering applications.
Check from the Play Store by date you have installed, if you have done it from the browser, you have to go directly to downloads and see the latest APK downloaded to your device. If you find it, go ahead and uninstall it and wait for it to be completely removed. from the phone itself and check that the audio is working for you.
The clear thing about this issue is that the sound is sometimes affected by those tools that you install without authorization and affect the same to a great degree. It happens to be ideal even that you pass the optimizer to see if passing this solves after removing the app on your device, which is another of the uses it has.
What if this doesn't work?
Now, it is possible that none of this will work. That from one day to the next your mobile has stopped being heard on the speaker. In fact, it is a problem that many users of certain smartphones have had, and it is a hardware problem of the speaker itself. What can be done in such a case? A simple restart of the mobile is the main thing. Reboot the smartphone. If the speaker still does not work, it is recommended to access the Recovery menu, and restart the mobile. To access the Recovery menu, turn off the mobile, and press the power and volume down buttons (if it is a Samsung it is Power On + Volume Down + Home Button), but ideally, you should look for how to access the Recovery menu or Download menu with your mobile in particular, because in each mobile it can be different. Sometimes, when accessing this menu, the mobile hardware is reset, and that may solve the problem.
Finally, you can restore the mobile to its factory state. In Settings > Backup and reset, you will have the option to perform a full restore. Of course, you are going to lose all the mobile data, so you will have to make a backup copy first. This step is the worst, because it will take you the longest, but it is the last option Before buying a new mobile, take it in for repair, or replace it if it is still under warranty. It is even possible that before replacing it, the store where you bought it will restore it to see if the problem is solved, so it is a step that you can save yourself.
