Microsoft has promised to make the Cortana for Android beta available publicly “in the next few weeks” after an early version leaked out last week. It’s already available officially to a limited number of people in the U.S. and China.

A number of users who are testing Windows 10 ahead of its release later this month received a survey from Microsoft via email, ZDNet reports. A small selection of respondents in the U.S. and China were then chosen to test the Cortana beta ahead of its public release on Android.

This early release was then leaked out by one user, and many others have since downloaded and installed it on their devices. However, many features are still missing from this build, and at this point it’s still buggy and unstable.

That’s expected with a beta, of course, but it’s likely the publicly release will be more reliable — and we won’t have to wait too much longer for it.

“In the spirit of the Windows Insider Program, we’re testing the Cortana for Android beta with a limited number of users in the U.S. and China before releasing the beta publicly in the next few weeks,” Microsoft said in a statement to ZDNet.
