Teams App - Loading Issues (Android)

Dear @Liza,

Thank you for taking the time to share such a detailed description of the issue. I completely understand how disruptive and frustrating this experience has been, especially when Teams is critical to your daily work. I’m truly sorry for the inconvenience you’ve been facing.

From what you’ve described, you’ve already exhausted most standard troubleshooting steps on Android (clearing cache, resetting the app, reinstalling), which helps me rule out several common causes.

To better narrow down the root of this issue and avoid asking you to repeat steps you’ve already tried, could you please help confirm a few targeted details below?

1. What Android device model and version of the Microsoft Teams application are you using on your mobile device? Have you checked for Teams updates?
2. Does this issue occur only with your work account? When you sign in using a personal Microsoft account, do you experience the same behavior?
3. Are other users within your organization encountering a similar issue?
4. Does the issue occur on all Teams chats and channels, or only with specific users?
5. Is Battery Optimization/Power Saving enabled for Teams?
6. If possible, please take a screenshot of the issue you're experiencing so I can better assist you.

In the meantime, please try some steps below and check if it helps:

1.Microsoft Teams update to the latest version. Version update history for Teams app deployments - Office release notes | Microsoft Learn 

2.Remove the account completely from Android: If clearing data didn’t help, try removing and re-adding your email account:

• Go to settings > Accounts > Remove school/work account > Reboot phone > Reinstall Microsoft Teams > Sign in only after reinstall (don’t let Android auto-add the account)

3.Check app permissions

Ensure that Teams android has all necessary permissions:

• Go to Settings > Apps & notifications > Teams > Permissions.
• Make sure all relevant permissions are granted.

4.In addition, please review and apply the troubleshooting steps outlined in the referenced article to determine whether any of them address the issue in your environment. Troubleshoot notifications in Microsoft Teams mobile apps

I noticed that the document includes fixes categorized by Android device type. I would appreciate it if you could check whether my device is covered.

Appreciate your patience and understanding and thank you for your time and cooperation. Have a great day!

Based on the described behavior (Teams on Android stops updating messages, no notifications, sending fails, and all local troubleshooting steps like cache/data clear, reinstall, and phone cache reset no longer help), the issue is most likely not fixable solely from the device side and may be related to:

• A device- or OS-specific problem with Teams on Android
• A known issue with certain Android builds or vendors
• A problematic app build that requires an updated Teams client from the store

From the available information, these are the concrete, supported actions:

1. If using a Xiaomi device or originally installed Teams from Xiaomi GetApps or a third‑party APK site (APKMirror, Aptoide, etc.):
   • Uninstall the existing Teams app completely from the device.
   • Open the Xiaomi GetApps store.
   • Search for “Microsoft Teams” and install the app that has the new badge, which replaces the original app.
   • Sign in again and verify that messages and notifications start updating normally.
   • This is required because the original GetApps/third‑party build will not update correctly and can cause persistent issues.
2. If using another Android vendor and Teams is crashing or behaving inconsistently after opening:
   • Confirm that the issue is not a broader Android/phone OS problem. For example, in a similar case on a Pixel device, the root cause was on the Android side and was escalated and fixed by the device/OS vendor.
   • If the problem persists across reinstalls and cache/data resets, contact the Android device vendor’s support to check for known compatibility or production issues with the current OS build and Microsoft Teams.
3. If messages are not loading or updating in Teams (even when the app stays open):
   • Try the web version of Teams on the same device by opening a browser and going to https://teams.microsoft.com/ and signing in with the work account. If the web version works reliably while the app does not, this further indicates an app/OS compatibility issue rather than an account problem.
   • If the web client also fails to update, involve the organization’s IT admin to check for any tenant‑side issues, policies, or conditional access rules that might be affecting mobile clients.
4. If notifications specifically are unreliable or missing on Android:
   • Ensure Teams has all required permissions on the device (Settings → Apps → Teams → Permissions → enable all required permissions).
   • Disable battery optimization for Teams (Settings → Battery → Battery Optimization → All apps → Teams → Don’t optimize) so the OS does not aggressively kill background activity and notifications.
   • Check for third‑party “cleaner” or “security” apps (such as Clean Master or Security Master) that may be blocking Teams notifications and either disable their notification‑cleaning features for Teams or uninstall them if necessary.
   • On devices known to have notification issues (for example, some Asus or Huawei models), ensure Teams is allowed to auto‑start and is listed as a protected app so the OS does not stop it in the background.
5. If none of the above resolves the issue and the app remains unusable despite:
   • Clearing cache and data
   • Reinstalling from the official store
   • Verifying permissions and battery/notification settings
   • Testing the web version
   Then the remaining options are:
   • Escalate through the organization’s IT/admin channel so they can open a formal support case with Microsoft, providing device model, Android version, Teams version, and timestamps/correlation IDs from failures.
   • Work around the issue by using the Teams web client in a mobile browser until a fixed app version or OS update is available.
