Xamarin Forms release apk blank screen on other device

MzrAli

Hi, I am trying to resolve this problem since three days. My Application working fine on my test device with Nougat 7.1. But when i install on other device 8.0, 8.1. after runtime permission , it stuck on white blank screen then close after a while.
I've done following troubleshooting but still same issue
1 - rename Mainpage
2- Disable Linker
3- remove all startup codes from Mainactivity
4- reset internet Permissions

Please help to resolve the issue.

Does the application require a dangerous permission? Like ReadPhoneState permission. If so, you need to grant it.

if (ContextCompat.CheckSelfPermission(this, Permission) 0= (int)Android.Content.PM.Permission.Granted)
{
    //execute you code
}
else
{
    RequestPermissions(new string[] { Permission }, 0);
}

Besides, if you set screen orientation to the Activity, delete the code and try again.
