There are no device specific sections here on the forum. One reason is, that the user interface is equal for all supported devices. (Some small differences between Nougat and Oreo exist)
Switching over from Android should be no difficult task, because /e/ is based on Android. If you are familiar with Android, then you will find a familiar user interface.
One difference is the default /e/-launcher “Bliss” that contains some concepts of Apple-OS and is developed by the /e/-Team, but it is mostly self-explanatory.
