* Does Threema support Live Tiles?
Please first check Threema's notification settings by going to WindowsPhone > Settings > notifications + actions > Threema
If you would like to show Threema messages on your lock screen, you can adjust its settings:
WindowsPhone > Settings > lock screen. Here you can add Threema in the menu "Choose apps to show quick status".
You can select Threema to show a detailed status as well. Despite such a setting, message contents cannot be shown in the preview of your lock screen or BigTile, because they are being transmitted encrypted and cannot be decrypted due to restrictions of the operating system. However, a BigTile can display the sender's name.
Please note that using the Battery Saver will affect the updates of your LiveTiles.
