Malware?

[db]

My phone went completely dead today after I installed, and uninstalled
again, a terminal emulator and a news group reader. Can this be malware
from these? My wife got it going again after some time, but it was
totally unresponsive for some hours.
Is there a virus checker I can install?

virus checkers on android are smoke & mirrors, given that no app
(including so called virus scanner) can see or touch another app's files.

Hi Andy,

The OP is likely one of those apple trolls but to your point, then how does
the Google scan work if "no app can see or touch another app's files"?

I'm not sure if Google Play Protect is "really" part of the Google Play
Store app itself, but inside the Google Play Store app is the Google Play
Protect settings GUI that controls that heuristic scanner which runs, by
default on every app install (even apps which are sideloaded) AFAIK.

In addition, by default, I believe the Google Play Protect runs once a day.
If no app can see another app's files, how does that scanner work then?

The only apples I get near are those off my tree.

Maybe I set the number of displayed posts too low, but my
one on terminal emulators is gone now (for me), so I'll
continue here.
Someone suggested Termux and I searched for it under
Play Butik (that's Danish, not sure what it would be
in English, Shop?) Anyway, I find a number of apps,
but none seems to be the Termux app itself. Like,
Learn Termux, .. Tools and Comm.., Andronix (??).
How do I get hold of the Termux app itself? Some
other emulators I found want payment.

I don't use it, but why would you download from somewhere other than
<https://packages.termux.dev>

[db]

Because Play Store (I now know the English name for it) is the
only way I knew how to install apps. I see that termux is
"deprecated" there. So, I googled the link, and get a lot of
text, but no clear instructions for how to install it on my
phone, which is not like my trusty Linux.

Hi Andy,
Thanks for that suggestion as I too was unaware of where the "official"
termux resided until you listed _that_ open source archive for Termux.
<https://packages.termux.dev>

Until I went there, in fact, I was unaware of this Termux security warning:
"Security warning: APK files on GitHub are signed with a test key
that has been shared with community. This IS NOT an official
developer key and everyone can use it to generate releases for
own testing. Be very careful when using Termux GitHub builds
obtained elsewhere except https://github.com/termux/termux-app.
Everyone is able to use it to forge a malicious Termux update
installable over the GitHub build. Think twice about installing
Termux builds distributed via Telegram or other social media.
If your device get caught by malware, we will not be able to help you."
<https://github.com/termux/termux-app#github>

For the record, your link provides the preferred Github link:
Home page: https://termux.dev (<https://termux.dev/en/>)
Github: https://github.com/termux

Which says "Get it on Github":
<https://github.com/termux>
<https://github.com/termux/termux-app#github>

And "Get it on F-Droid"
<https://f-droid.org/en/packages/com.termux/>
<https://f-droid.org/repo/com.termux_118.apk>

But not, interestingly so, on Google Play Store!
<https://github.com/termux/termux-app#github>
"Termux and its plugins are no longer updated on Google Play Store
due to android 10 issues and have been deprecated. The last version
released for Android >= 7 was v0.101. It is highly recommended
to not install Termux apps from Play Store any more."

I always have trouble with Github finding the actual APK so it's here for
others to benefit from without having to click around trying to find it.
<https://github.com/termux/termux-app/releases>
<https://github.com/termux/termux-app/releases/tag/v0.118.0>
For example, for arm64 (I'm not sure why it says "debug" in it though)
<https://github.com/termux/termux-app/releases/download/v0.118.0/termux-app_v0.118.0+github-debug_arm64-v8a.apk>

BTW, the F-Droid note says it's more "universal" since it says
"F-Droid does not support architecture specific APKs."
<https://github.com/termux/termux-app#github>

It seems the F-Droid one is more universal from that, but I always have
"issues" updating existing installed F-Droid apps due to some "signing"
problem I don't understand.

Now, as for the termux that is already on my system, I need to look in my
APK manager to figure out _how_ I had installed it in the first place.

Thanks for letting us know that the Google Play Store termux is not the one
we want (there are many there, besides, as it's open source code anyone can
copy it).

My main request for advice is which of the two bona-fide termux download
links would you suggest? The Github architecture-specific or F-Droid
universal?

And how would you suggest auto-updates be set up if that's what folks want?

Actually, let me file this as a separate thread so that others can
find it more easily ten years from now when they run a search.]

Please respond there if you're going to reply as that helps more people
find it because of the keywords I placed into the title to aid searches.

which, in this case, is to discuss the peculiarities of the Termux APK.
