If it works correctly and you have any other cover or bumper, it is recommended that you also try it to rule out if it happens only with the previous case or with anyone.It would be very strange that I pass you with all the covers, but if you are in this situation and you have already proven that these are those compatible with your iPhone, you should go to Apple because it is likely that by some factory defect they are moved from the site where should be.

Close apps and all the processes in the background

As we previously advanced, on many occasions it happens that the most stupid and faster solution ends up being effective.With a multitude of iOS software problems, why wouldn't it be able to work in this case?Try to close all the applications you have open and then verify if the volume already works correctly.If it still does not work proof to complete the iPhone several seconds and then start it again.

What happens when the device turns off is that all the processes that are being executed in the background are closed, these being the main causes of some problems that make the performance not adequate.It is likely that there is some kind of problem that prevents executing a change in volume on the iPhone through the buttons, so resetting the terminal you will ensure to eliminate it if this really is the origin of the failure.

It could be iOS the cause of the problem

Yes, the iOS operating system is fully prepared to work on the iPhone.Now, like all software, you can have your problems.Luckily these are usually solved in a simple and often fast way.In these next sections we tell you that you should review so that, in case this is the cause of your problem, you can solve it.

Check if there are software updates

While these types of failures are not usually common in a normal version of iOS, the truth is that it cannot be completely ruled out. Nuestro consejo al respecto es que vayas a Ajustes > Actualización de software y descargues e instales la versión más reciente de iOS que esté disponible para tu iPhone, si es que la hay.These updates not only include aesthetic and functional news, but also correct failures such as the one we are describing.

If you have evidence that in the current version of iOS you have problems and yet there is no more recent update, you will have no other to put together patience and wait for Apple to put a solution with an upcoming update.When these situations occur, the company usually acts quickly, so it could be just a matter of days that said version is corrected by correcting the problem.

Are you in an iOS beta?Remove it

If you have a beta profile of iOS on your iPhone, either because they are developer or wanted to try the novelties of a future version of the system, it is recommended that you take it to make sure that this is not what fails.One of the risks that have this type of versions is to show bugs like this, especially if it is still in a premature phase of development.If for professional reasons you need to continue having the beta, you will have no other than wait for the launch of the final version to check whether or not the problem is solved.It should be noted that Apple does not take care of device repairs with an installed software beta.

If only in some applications

If the problem to raise or lower the volume is happening only in some application, but in other parts of the system it is possible to change it without problem, it is highly likely that app that has a problem.The first advice we give you in this case is to update the application since its corresponding section in the App Store.If there is no new update or continue giving failures even after updating, we recommend that you completely uninstall and install it again.

If after this he continues to give problems and it is only in an application, you will have no choice but to wait for a future update to correct it.To make sure that developers are aware of the problem, we recommend you contact them and cut it.From the file of this application in the App Store you will find a link to its contact.It should be noted in any case that the fact that the volume animation does not come out does not mean that it is not modified.It is possible that by some other bug this does not occur on screen.Therefore you must check if the volume really varies to the pulsrs the buttons.

The definitive solution to software failures

In the end the most effective way to end software problems, taking into account that it was, is to format the iPhone.There are several methods for this, with their own singularities as we will explain below.

Make a backup first

If you have the possibility to do it, do it. Ya sea una copia en iCloud mediante Ajustes > tu nombre > iCloud > Copia de seguridad o conectándolo a un ordenador.For full restoration and ensure that software failures are not presented, we recommend configuring the iPhone as new after restoration, without loading any copy.However, we believe it is important that the formato is done does not end that failure and you want to leave the device as you had it.However, remember that there are certain data such as contacts, notes, photos or calendars that synchronize with ICLOUD regardless of whether or not they are made a copy.

Delete the entire iPhone from the settings

This is the fastest method of formatting the iPhone.Although to be fair with the truth, the iPhone is not really formatting, but what what it does is to delete the data to overwritten them with the new ones, so some errors could continue present despite the fact that for practical purposes you feel that you are seeingThe device as if he had just left the box.If you also do not have a computer by hand, it will be the only option you have.

This is done by entering adjustments, then going to general and sliding to down to restore.Once here you must click on "Delete content and adjustments".Surely after that you are asked for the device security code and/or the Apple ID password with which you are logging in the terminal.It will be a matter of minutes that then deleted everything and the initial configuration appears.

Perform a complete formatting

This is the complete method of formatting of the iPhone, completely erasing its content and reinstalling the zero operating system.It can be done with a Mac through Finder if you have Catalina or later installed or from iTunes in Mac with MOJAVE macOS and previous, as well as the PCs with Windows.You must connect the iPhone to the computer by cable.Once you have done this and open the program you will only have to go to the management of the device and click on the "Restore iPhone" option.

If you couldn't solve it

If despite following everything commented above you have continued to have problems, everything indicates that it is a hardware failure.For some reason your iPhone buttons have broken down.If it has been for any blow or similar it will not be covered by the guarantee, but if it is a defect oblivious to a misuse it can be covered by Apple itself.Be that as it may be to contact the technical service.

Either in an Apple Store or a SAT, you can request an appointment and ask to review the device.After that you will be offered a solution that, in case of demanding a repair, will be shown before a budget that you can or may not accept.On some occasions it could be free if it is determined that it is a factory failure.Remember that you can ask for this appointment from the iOS support app or from Apple's website.
