# Read Status & Unread Count (Legacy)

### Reading Status and Unread Count <a href="#reading-status-and-unread-count" id="reading-status-and-unread-count"></a>

The `ChannelRepository` object exposes a `totalUnreadCount` property that reflects the number of messages that the current user has yet to read. This count is the sum of all the `unreadCount` channels properties where the user is already a member.

#### Version 5 (Maintained)&#x20;

The `ChannelRepository` provides `getTotalUnreadCount()` method. It's giving the flowable of the number of messages that the current user has yet to read. This count is the sum of all the `unreadCount` channels properties where the user is a member of.

Version 6

The `Channel` object exposes a `unreadCount` property that reflects the number of messages that the current user has yet to read. This count is the sum of all the `unreadCount` channels properties where the user is already a member. It also provides hasMention which is a boolean presenting having a mention for current user in channel.

{% endtabs %}

The `startReading()` and `stopReading()` methods let the server know that the current user is reading a channel. After the `startReading()`and `stopReading()` methods are called, the `unreadCount` is reset to 0.

You can call both methods as much as you'd like, the SDK takes care of multi-device management: therefore a user can read multiple channels, from one or multiple devices at the same time. In case of an abrupt disconnection (whether because the app was killed, or the internet went down, etc.), the SDK backend will automatically call the `stopReading` on the user's behalf.
