Ionic v3 app closing

Question

I have an application with a login screen and another home, run and Clean on a Samsung S6 Android api 23. I created a new project with minimum api 19 and maximum 28 and when I published some devices informed q the app generated several errors and closed, downloaded to version of android 27 max, same thing, now downloaded to the maximum version 26 and solved for some devices, but continues to give the same problem in devices with api 27+. In none of the lab versions the app shows any kind of flaw, neither when it runs nor when I release it for publication. I’ve deleted the android folder, Node modules and there is no indication of error in anything, put below my settings as I’m with no idea what to do to solve the problem:

What is making me desperate is that it does not generate errors, only when the customer downloads the application via Playstore and on his device which is a Samsung S9. I have idea that the problem may be related to Ionic/Cordova/android versions but I don’t know what to do.

Thank you in advance to all who can give me a light.
