A full copy of Samsung's androids on an emulator, is this possible?

Question

Android

Hello Formers. I am developing an application for android and I had a problem on a specific device, but I do not have the device itself and there is no way to borrow it for a long time in order to fully conduct testing. I want to run a copy of this device on an emulator. Specifically, I need to concoct a copy of SAMSUNG J7 on android 8.1.
Along the way, I will describe the problem itself. My application checks the data from the database at startup, and if there is certain data there, then the working activity is immediately launched, and the authorization activity is closed ( finish() ). Accordingly, if there is data on the active session in the database, then the application, when minimized and expanded, goes into a working activity, even if the application process was killed from the outside. So, on emulators, all this works as it should, on most devices it also works as it should, but on SAMSUNG J7 with android 8.1, when minimizing and expanding, the working activity does not open, but the authorization window remains. Alas, I don’t have a device, I can’t take it for tests, so I don’t understand what the problem is. Therefore, I want to create the same environment in the emulator, but xs how. What can you advise? So, any thoughts on the issue?
Thank you in advance.
