Thanks for your interest in Android compatibility!
If you have questions about Android compatibility that aren't covered in this site, you can reach us in one of a few different ways. To get the most out of any of these options, please first read "Getting the Most from Our Lists" on the Community page.
For General Discussion
The preferred way to reach us is via the compatibility@android.com address.
For CTS Technical Questions
If you have specific issues with the Compatibility Test Suite that require you to disclose information you'd prefer not to be public, you can contact an email address we've set up specifically this purpose: cts@android.com. This email address is for cases that require disclosure of confidential information only, so general questions will be directed back to the public android-compatibility list. Note also that this list is for specific technical questions; general inquiries will also be directed back to the android-compatibility list.
For Business Inquiries
Finally, business inquiries about the compatibility program, including requests to use branding elements and so on, can be sent to the address android-partnerships@google.com. Like the CTS address, this address is for specific, private inquiries; general questions will be directed back to the android-compatibility list.
