Hi Binjan,
Thanks for using Syncfusion support.
We would like to let you know that the pixel density will vary between emulator and device. Android accelerated Oreo X86 which has the minimum screen resolution when compared to Mi device, so based on this screen resolution the template allocates the size to fit in the screen accordingly. Further these size allocation will be done by the android framework and not from our side.
Regards,
Gnana Priya N
