It's almost a year since I got mine, so I can't remember now- but mostly the nonsense stuff that never gets used; S-planner comes to mind and you'll probably find some duplicated Samsung and Google app's, just dump the one you are less likely to use. I wanted mine as streamlined as possible as it is a dedicated tablet for my DJI drone. The DJI Go! app is very resource-hungry and it's not something you want to crash- neither the app nor the drone shortly afterwards! But to be fair it never even felt laggy so perhaps I was being over-cautious.
