I’ve been using the AirPods (2nd gen) for S8, Flip3, and now Flip5 without any issues. However, you won’t know the battery level (unless I think there’s a 3rd party app for android), but since you mentioned your iPad you can quickly check that way too. Also, there’s no controls like you would have with an iPhone (ex: music stop playing if you take one off, the tapping to control volume, etc)
