I managed to force-install the application on Android version 12.
I checked it on version 14 - it also works.

The warning message that asks about continuing the installation is misleading - because when you click Ok, the installation menu disappears, but when you click on the text of the message, on the contrary, the installation continues.

I am solved the sound problems.
I had to bend one of the contacts, which was shorted to one of the channels....

That's a question (and criticism) for my colleague from China.
At my insistence that it stick to my original pcb design; he persistently refused and drew his own version of the pcb.
So... I, as the author of the project, bear no responsibility for any sloppiness in the production of that pcb and the arrangement of components on it; if not done directly by me.
China and Serbia are very far apart. I have no theoretical chance to supervise, much less control, the production of those kits.
In defense of my colleague from China; I can say that I stand behind the claim that he is a very honorable and conscientious man.
But... we all make mistakes from time to time...

...I have a question about software for android: I was only able to run the apk file on an old phone with the seventh version of android.
Is there an updated version!?
I would really like to receive telemetry data from the gradiometer in real time on my phone.

The Android software has been successfully tested from Android version 4.2 to Android version 12.
And the software (apk) has proven itself flawless in all possible tests.
But as someone who worked professionally in a software package development company ten years ago... I know from (bitter) experience that there is always an exception that will deny even the most honest claims at the worst moment.
Can you explain how the software behaves on your Android device? What is the device in question and similar questions?
...
I recently replaced my favorite Android phone with an iPhone.
But I still keep my old phone and my apk on it.
I checked now; phone is Samsung S7 with Android version 8.
Apk works perfectly.

Damn politics

Agree.
We "small and ordinary" people cannot live and function normally.
While the elephants fight; the grass suffers!

The new store is not completely normal, it will take a week or so to display in the EU and the UK. Russian friends can not view the goods under the store, you can check through the following links,

Since I rarely go to the forums, I don't know what's going on here. The sound problem is that you can add speakers, right next to the headphone jack, and it can only use standard 3.5 mm headphones, can't use headphones with microphones,

In order to let Russian friends can also buy, the new store has been launched, the product after the approval can be purchased one after another, and for African friends set up a dedicated link, this is the store address:

Here is how it usually sounds. Keep in mind that plastic enclosure with its "volume" amplifies the audio to certain extent.
Don't get confused with the options and features you see on this video, it is old version. You have the latest one.

Hello!
I have very quiet sound from the headphones that I connected to the board. Is this how it should be!?

Probably yes, if the headphones resistance is too high.
You can try with 4-8 ohms speaker to check if there would be louder audio.
Audio at such device is not very important. Good to have it, though you lose nothing if you don't.
Most important is Android or Windows software and what you get on 2D/3D display of measured data.
Or... you can connect piezo there too.
