Active session lock lets you know when an Android cloud phone or browser profile is already running on another device. It helps your team avoid overlapping sessions and keeps profile data consistent. 

Need to continue on your device? You can deliberately unlock and take over the profile – just check with your teammate first so you don’t interrupt their work.

➡️ Hover over the active-session icon → click “Unlock” → refresh the page if needed → click “Start”. 

How to stop the session normally

This is the best option when you or your teammate can access the device where the profile is running.

1. Save any work in the active profile
2. Find the profile on the device where it is running and click “Stop” in the profile list
3. Wait for the profile status to update
4. Refresh the dashboard on the other device and click “Start”

The profile is now ready to use on the other device.

How to take over a profile on another device

Sometimes you can’t stop the session from the original device. In that case, you can deliberately unlock the profile and continue on your current device.

1. Find the profile in the dashboard
2. Hover over the active-session icon and click “Unlock”
3. Refresh the page if the status does not update and click “Start”

If a teammate may still be working in the profile, give them a heads-up first. Taking over the profile may interrupt their session or unsaved work.

How to unlock several profiles

Need to clear more than one active session lock? Click “Unlock all” in the top-right corner of the dashboard, then refresh the page.

Use “Unlock” when you only need one profile. This helps you avoid interrupting other active sessions by mistake.

What to do if “Unlock” is missing

If the profile is no longer running but “Unlock” does not appear, a stale .lock file may be left behind after a crash or incorrect shutdown.

.lock files

.lock files are temporary files apps make to show a file or resource is in use. Here's why you can delete them:

• Fix stuck apps: if an app crashes, leftover .lock files can trick the system into thinking it’s still running
• Stop errors: these files might block your app from starting or working properly
• Clear update problems: if an update or sync gets interrupted, .lock files can block future attempts

Deleting .lock files is like hitting reset – it clears up the mess and lets your app run smoothly again!
