There are 3 (three) ways to update your OnSign TV players:
1. If OnSign TV was installed through Playstore
You can activate the option Update Automatically or you can update yourself at Playstore.
2. If OnSign TV was installed manually in a rootless device
You can download the new version and update it manually, without removing the old version.
3. If OnSign TV was installed in a device with root access, or in a Rockship device (System version), or in an IAdea Promotional Player (or IAdea Version)
You can update a player directly through the Players tab on your OnSign TV account. After you've logged in, click on Players in the header, then select the checkbox corresponding to the player you would like to update and finally click on the button Update Software that will appear above it.
