I also have a Samsung Galaxy S7 and have noticed surprising slowness. I just updated the app, and noticed that loading a new chapter is still slow when I am looking at a project. With two national language translations, the vernacular translation, and it’s back translation open, I selected a different passage. I counted a total of about 5 seconds of delay in waiting for menus and content to appear. As soon as I closed active projects and looked just at resources, all slowness went away.
