Accessing and using Microsoft Teams on smartphones and tablets across platforms
Hi, NimitPujara,
My name is Didi. I'm happy to help you today.
On a mobile device, our presence status changes to Away whenever the Teams app is in the background. It is by design.
At this time, manually setting it to Available is not possible. You may submit a request for this feature at https://aka.ms/TeamsFeedback or from the mobile app, go to Help > Suggest a feature.
Best regards,
