BlackBerry has put the brakes on the BlackBerry Messenger (BBM) rollout for iOS and Android and offered an official statement to explain the situation.

According to the company, users on Android have installed leaked versions of BBM and those apps were causing "issues." Consequently, BlackBerry has decided to halt the BBM rollout for the time being, until it can solve the problem.

As it turns out, an unreleased version of BBM for Android has made its way online before the app's official launch. More than 1.1 million active users have reportedly downloaded the app in the first eight hours, while the official Android app was not even out yet. This unreleased, unofficial version caused some issues and BlackBerry is trying to sort them out.

"Our teams continue to work around the clock to bring BBM to Android and iPhone, but only when it's ready and we know it will live up to your expectations of BBM," said the company. "We are pausing the global roll-out of BBM for Android and iPhone. Customers who have already downloaded BBM for iPhone will be able to continue to use BBM. The unreleased Android app will be disabled, and customers who downloaded it should visit www.BBM.com to register for updates on official BBM for Android availability."

"As soon as we are able, we will begin a staggered country roll-out of BBM on Android and continue the roll-out of BBM for iPhone. Please follow @BBM on Twitter for the latest updates and go to www.BBM.com to sign-up for updates about BBM for Android and iPhone. These issues have not impacted BBM service for BlackBerry."

If you are among the roughly 1.1 million people using the unreleased, leaked version of BBM, it is advisable to uninstall the application before BlackBerry takes its steps to disable it. If you want to get BBM for Android up and running again, check out the company's available channels listed above, register for updates and follow the official instructions.

BlackBerry has not offered an exact date for when it would resume the BBM rollout for Android and iOS, but should solve the issue soon.
