Honor's FM Radio

[Qihe]

Hi, testing "FM Radio" app embedded on my Honor 200 lite (Android
14) it requires to plug in audio jack or adapter to go. This
Honor doesn't come with a jack port. So when I plug in a "usb-c
to jack" adapter I get a "wrong port" warning from FMRadio app (
...although the adapter works fine playing any other
multimedia).

According to Termux there is a FM chip and it's running, isn't it?
getprop | grep -i fm
[init.svc.fm_hidl_service]: [running]
[persist.vendor.connsys.fm_chipid]: [mt6631_6635]

It doesn't seem an hardware issue but I can't uninstall this
(bugged?) FMradio app rootless.

How to fix it?

When the FM chip uses an *analog* jack as antenna input, USB-C wouldn't
help you at all. Maybe Honor just forgot to remove the app since the FM
chip is useless without analog jack.

Maybe you can just disable it, so you won't see it any longer.

It actually needs an earphone on the audio jack port, it is a hard
hardware requirement. It works as antena.

You can not. You should be able to disable the application, though.

You should be able to complain to the vendor, faulty radio feature.

You can't disable it either. What com.android.fmradio is doing exactly
is puzzling for about a decade now.

When I will be about to replace my phone for good, I hope to remember to
freeze it and see how it will go.

p.s. I know, but searching through xda-developers is a bitch.

My Android phone is unrootable (as far as anyone on XDA knows), and yet, I
can disable/stop/remove from the user partition almost any app I want to.

All you do, essentially, is run this command on the device or on a PC.
C:\> adb shell pm uninstall --user 0 com.android.fmradio

I have been able to disable/stop/remove any app I wanted, with the
standard application menu. I just checked with the radio app. However,
not with the "messages" app, so maybe there are privileged apps.
Obviously I'm not going to try remove that app to check on it.

There is no risk if you know what you're doing when using adb.

You do you, but just so the others lurking know, if you're non rooted, you
have only two possibilities with adb on removing unwanted packages.

1. Most apps will be removed from the user partition without complaint
2. Some apps (one out of a few hundred in my experience) won't remove

I don't know what makes the one out of a few hundred not remove, but it has
happened (rarely) to me so I know that it is a possibility (albeit rare).

Anyway, there's really no risk because you can always reinstall any app you
remove using adb because it's not actually removed from the root partition.

So there is no risk - but you do you. For sure, a few times I've removed a
package and then regretted removing it - but it's easy to get it back.

C:\> adb shell pm uninstall --user 0 com.package.name
C:\> adb shell cmd package install-existing com.package.name
