Replacement
Will Apple replace a device that has already been replaced by Apple in the last 90 days or so?
Devices replaced by Apple under warranty or other exchange programme also have a short warranty - which may vary by country/region. If your device has developed a fault, contact Apple Support without delay.
You can contact the Support Team using the Get Support link at top-right of this page. Alternatively, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:
