iPhone X Can’t Quit/Close Apps While On Phone Call

This is what Apple says about apps running in the background (Apple words are underlined and bolded) -

After you switch to a different app, some apps run for a short period of time before they're set to a suspended state. Apps that are in a suspended state aren’t actively in use, open, or taking up system resources. With Background App Refresh, suspended apps can check for updates and new content.

If you want suspended apps to check for new content, go to Settings > General > Background App Refresh and turn on Background App Refresh. If you quit an app from the app switcher, it might not be able to run or check for new content before you open it again.

It is not necessary to continuously close apps.

I’m experiencing the same issue. No matter what I do (hard reset, reset settings, restore from backup, I’m still unable to close apps while I’m on a call.

To me, it looks like a glitch that Apple needs to fix

"It is not necessary to continuously close apps."

I'm kinda of really tired of hearing this response.

All the troubleshooting steps from forums, Apple, Genius Bar, etc. say first close all apps. But Apple continues to insist we don't need a "close all" button. And not being able to close apps while on a call, and having the "low memory" supposedly non-existing condition occur and knocking out my bluetooth FIRST, is not acceptable. I wear hearing aids and the first thing that happens is the bluetooth for one OR BOTH hearing aids drops out. The "fix" is to close all apps. Hard to do when prevented while on the phone call I'm trying to also be a part of. There are some definite lessons Apple needs to take from the Android world, I still prefer the Apple ecosystem and more consistent behaviour/design between apps, but silly issues like this where Apple insists on drawing a line in the sand are ridiculous.

The other "brilliant" response I get from even escalated Apple support is to reset my phone with no restore from backup because "some app" I have installed "might" be causing whatever problem we're troubleshooting. Not having the capability of troubleshooting this without the user having to go through the very inconvenient process of "starting all over" is patently not acceptable. For Apple to provide no diagnostics (like even telling me what process/app is killing the performance of my phone "right now") is another sign of either laziness on the part of their developers or just a complete non-caring for their power users. I use a ton of apps during the course of a day (usually at least 100 in the multitasking picker by the end of a week if I don't keep closing them) and forcing me to "reset everything" is just not a valuable or practical "answer."

Me too, for what it's worth. I was just working on a technical issue with Apple (over the phone) and they said "close all open apps," and I couldn't. We had to hang up first.

Totally Agree! Apple,, allow close of apps while on phone call & create a close all button!
