I just recently bought GMS2 and the GMS2 Mobile Module. I just read through all the documentation to set up the Android Module and was able to successfully run my first app through GameMaker! While I have published apps already to the google play store they were written in C# through the Unity engine, so please bear with me as I am quite the noob with GMS2. I am trying to figure out how to set the room size to fit my Samsung galaxy s8 and other recent Android devices as I am targeting API 23. I am trying to develop a vertical game so I'm quite lost on how to make a comfortable room to work in GMS2 and have it play without black sidebars on my device. I have been reading up on aspect ratios and 16:9 won't work well on the S8 as it uses a very unique ratio. All help is much appreciated!
