We can't really help you, its not clear what you are asking. We already explained however how downgrade protection works, which seemed to be what the situation was. The error you described is what prints when downgrade protection is set off.

hicks Without knowing which versions of which APKs it's hard to say. Some old APKs may be too old to run on a modern machine -- for example, 32-bit binaries.

hicks 'm not sure if I'm clear enough.

If absolutely no APK file arriving via MTP from a USB-connected PC can be opened, something odd is going on.

But if a collection of very-old APK files, such as APKs containing 32-bit binaries, can't be opened, that is not at all surprising.

That is why I asked which versions of which APKs are in question (de0u).

I have copied couple more test files over the USB from PC, and I see weird behavior all files takes about 15sec to appear in the phone folder as I am dropping then in to the phone download folder open in PC. when they finally appear on the phone they are about 45 KB bigger than left PC. (Apk files only) And yes all apk files won't open or even anyhow responds to tapping on them. Different files like jpg, txt and etc will trigger popup with choice of applications to be used to open that particular file extension, yet no popup for apk files.

I'm not sure if I'm clear enough. Maybe grapheneos just letting me know I expecting too much out of it right on the start? Lol

Thnx.

Probably because a different file system is used

hicks yet exactly same app downloaded through my laptop and copy pasted to phone through usb will not launch it self and install.

Can you check the hash of the files to see if they are really the same app?
also what does app verifier say? can it open both

hicks

I hope there is some simple explanation to this behavior. Other ways donno what to think about it.

hicks

I don't know what version of apk it is, but nothing that I couldn't open and install on my other android devices that aren't that old themselves. All file shows up on the phone yet only apk are non responsive. Let me check this files in apk tester app...

hicks

OK so apk analyzer says this apk target was android 7.1.2 Nougat. Is that makes it too old for current OS gens?? ;)

The two controlling factors are the API target and (if it's not a pure Java/Kotlin APK) the target architecture. But I do think an Android 7 APK may be too old.

...I'm no computer or software tech myself. Let me try pass throu usb some more apks including some current ones..

hicks

Hi again.
So I had downloaded bunch of current apks and copy paste them in to graphene download folder. I also dropped bunch of different files, all of them opens fine except for apk one. In have also installed apk file through vanadium browser just fine so there is something that is not allowing me to use my own files to be installed. Funny is to see same apk file that is now sitting in download folder that I had downloaded through web browser responding to taping and launching installation, yet exactly same app downloaded through my laptop and copy pasted to phone through usb will not launch it self and install.

Thnx.

can you please check under settings > Apps > special app access > install unknown apps and tell me if "files" or any other filemanager you are using is set to "allowed"?

hicks

I went through entire phone looking for some safety feature to be unlocked but I haven't found anything.

hicks

final you always prevent traffic in post slapping solved badges on them?

hicks

dhhdjbd

I'll try if I will know how to do that. But both APKs were downloaded with in minutes from each other from same official web site. BTW not toobmany APKs is possible to have downloaded thus days as every one send you straight to official Google store to obtain there software but as I say. The only differences was the way I got these files to Graphene OS internal folder either direct download through web browser , or get them copied via USB.

At this point I have no idea if USB transfer is not permitted on Graphene, or there is some settings that are switchable?

hicks

Hey Guys.
Thank you for your interest in this matter. I put my Graphene phone on a side. But let's get back to it.

tumbord

So I already went there just looking for something that will strike my eyes, but nothing there.
There's only couple of apps mentioned from few that might need permission to "install unknown apps" like internet browser, google app store or WhatsApp for example. But nothing about apk files that are placed in the Graphene OS internal folders through MTP/USB connection.

hicks

Thank you Spring Onion for removing "solved" tag.

hicks

So I've run AppVerifier and all APKs pass and for already installed apps googles framework and play services filed checkup and are marked red.
I have everything updated and reinstalled yet same result.
