How to understand why the application is not installed on an android device?

Question

Android

I made a simple flutter application. I run it on emulators, with different APIs (16, 24, 28) - it works.
I sent the file to a real device, I get the message:
"The application is not installed"
Phone: Xiaomi Redmi note 8 pro and Samsung galaxy s5

flutter doctor -:

All sdk latest. How to understand what is not suitable on a real device?

PS the project is compiled only if build.gradle says:
compileSdkVersion 28 - could this be the reason? on all real devices api below

UPD. Connected the phone to debugging. At the same time, the compiled apk is installed and running.

I made a release - the application is installed, but does not work))) (this is another question)

As a result, the question is: Why is apk not installed on the device, in debug mode?

Answer 1

In general, they support quite old devices on the dock , I advise you to look at third-party plugins for dependencies, and also allow installation via usb and from unknown sources. Most likely, miui and one ui firmwares have additional installation restrictions.
I advise you to look at the logs, perhaps there will be indicated the reason that interferes with the installation
