I'm looking to get back to Sailfish OS as my daily driver and I wanted to know the differences between the XA2 versions in regards to Sailfish OS? I know what the physical differences are (screen size, resolution, battery capacity etc.) but I'm looking for info about how those differences impact the OS? Does the different format of the Plus have any impact on Sailfish for example? Does the bigger batteries of the Ultra and Plus mean longer battery-life or does the bigger screens eat the battery faster? Does the XA2 dual-sim work with Sailfish? Any info would be most welcome
