You’ll need to update Microsoft Teams quickly if you’re an Android phone user. According to the previous XDA Editor in Chief Mishaal Rahman, Microsoft has fixed a Teams bug that caused 911 calls to fail on devices running Android 10 or later. Reddit user KitchenPicture5849 discovered that installing Teams, but not signed in, will prevent emergency calls from going through. The phone might say the call was active and ring once, but never properly initiate the call – call logs won’t show anything.
Rahman and his friend Koba and Zhichowski identified the cause. While all Android calling apps will attempt to instantiate the PhoneAccount class in the OS, Teams was creating instances every time a user started the app “cold” – increasing the chances of a sorting issue that prevented calls from going through.
Google spoke to a Reddit user and revealed that both the company and Microsoft are planning fixes. In addition to a Microsoft patch, Google is bringing an update to the Android platform on January 4th that should address its side of the problem. You can delete and reinstall Teams to clear any redundancies from PhoneAccount, and staying signed in should prevent any mishaps.
Google said this only affected a “small number of devices”. The issue, however, was gravity. This could have prevented someone from making a life-saving call through no fault of their own.
