Look, I say this as someone who’s firmly in the Windows PC + Android phone camp: just buy a refurbished iPad to use as a dedicated Zwift tablet. No Android tablet is going to have the smoothness or longevity.
Set up an alert on RefurbTracker - the best deals are direct from Apple. You don’t need current gen - something 1-2 gens old is fine.
If you have to go Android, don’t skimp out with a second-tier brand like Huawei or Xiaomi - at least get a Samsung as others have suggested.
