Display Issues in under larger scaling settings

[gaosher]

hey, thanks for your effort for developing this awsome app! in the process of using Flyn DecSync, i found some adaptive display bugs under largest font size and largest display size. Screen shots: checkbox "Enable DecSync synchronization" overlaps with the back button. i belive the buggy views are CheckBox @id/intro_directory_checkbox in activity_intro_directory.xml and ImageButton @id/back in appintro_intro_layout.xml

hope this info will help to locate and fix the bug :)

app version: 2.7.2 device: Pixel 2 Android version: 10.0 screen resolution: 1920 * 1080
