I have the note air 2 plus, the battery is only bad if you have WiFi on, with WiFi off it can last weeks. It’s a really nice device otherwise.
Some of the apps allow blocking of instances, I use Sync For Lemmy and I blocked pornlemmy and lemmynsfw and I don’t see porn anymore for the most part, there are still some stray nsfw communities on other instances but I rarely see any of their content
Used to have these problems when we were children and playing fighting games with my brother with one keyboard or guitar hero clones that need you to press multiple buttons at the same time, that’s the only use case I could think of. I don’t know if there’s any modern software that requires you to mash more than 2 or 3 buttons at the same time
