Some small nitpicks: you don't have to add them if you don't think its valid.
- Rearrange the help screen with the sync notifications first, then the file transfer, the remote control. I would hazard a guess that thats what people want the most. Again not sure so feel free to use your discretion.
- Googles HIG guidlines state that you shouldn't really display a screen showing ui, rather you should overlay disrections over the UI. https://material.io/design/communication/onboarding.html#top-user-benefits-model. However I also don't know how many people actually follow this.
