# Live chat
You can share messages with other users both inside and outside video meetings.
When a user signs in to the application on a new device, the chat history saved on the previous device will be synced across devices.
If you connect to TrueConf Server which is below 5.0 version, the chat history will not be synced across your devices.

With this messaging platform, you can:
Send text messages
Edit, forward, and delete text messages
Search for words and phrases in chat messages
Create a conference on the fly.
All messages that you send can be edited. To do it, tap on a message and select Edit.

The message will be marked as “edited” (the date of editing will also be specified).

Besides, you can tap and hold on a message to open the context menu. The following options are available:

Then, you will see a slideshow management widget with the buttons that will allow you to switch between slides and stop the slideshow.

# Content sharing
When participating in conferences from a client application you will be able to share your screen and show slides created in popular presentation programs and online editors such as Microsoft PowerPoint, Libre Office, Google Slides, etc. Please note that you will need to install the corresponding software to open these files on your device.
Your screen will be seen by all conference participants who joined from TrueConf client applications and from browsers (via WebRTC). Besides, the content shared during conferences can be recorded.
In the meeting control panel, tap on and select Screen sharing.
When the application is run for the first time, you will see the Display over other apps settings. Find TrueConf for Android and activate the switcher.
Then, you will see a pop-up window notifying that you can start sharing. Tap on Start now.

Then, the application will be hidden (minimized) and you will see the content management widget. It will be displayed over other apps all the time while you are sharing content. Other participants will see the content and video from your camera.
# Content management widget

The content management widget includes the following components:
— stop sharing
— maximize (enlarge) the widget; you will see the video window of other speaker or your self-view (it works similar to the window in the conference widget)
— enable screen annotation mode
— the widget title: you can tap on this UI element to drag the widget to any part of the screen.
When screen annotation mode is enabled, the widget will look in the following way:

— clear all annotations

Screen annotation is one of the main features in TrueConf for Android because it enables users to highlight the most important parts of the shared contant or add key points:

# Content sharing by multiple participants
Two conference participants can start a slideshow at the same time. In this case, you can select and zoom a content window in the content preview screen to make sure you do not miss any details.
