Getting Started and Account Basics
Phone Number Verification
WhatsApp App Wiki details how account creation begins with a valid phone number and SMS or call verification. Your contacts list syncs only after successful verification, which establishes your WhatsApp identity.
Profile Setup and Visibility
You can set a name, photo, and About text that appear to chosen contacts. The wiki explains how privacy settings let you hide your profile photo, About, and status from everyone, contacts only, or specific people.
Messaging Features and Best Practices
Text, Media, and Document Sharing
The wiki outlines supported formats for images, videos, PDFs, and other files, including size limits and how original quality is preserved when sharing. You can learn how to locate past conversations using search within chats.
Read Receipts and Message Info
WhatsApp provides delivered and read indicators, and the wiki clarifies what each status means. You can also see timestamps, edit limitations, and how to use the info screen to check contact details and media storage usage.
Calls, Status, and Privacy Controls
Voice and Video Calling
Guide entries describe how calls use your data connection and offer tips for stable performance. You can adjust microphone and camera choices per call and manage call permissions in device settings.
Status and Disappearing Messages
Status allows temporary content that disappears after 24 hours, while Disappearing Messages can be enabled per chat or group. The wiki explains how these modes affect what you see and share, and how they interact with backups.
Encryption and Data Security
Each conversation benefits from end-to-end encryption, meaning only you and the people you communicate with can read what is sent. The wiki covers safety number verification and how to review encryption keys for added assurance.
Managing Notifications, Data, and Performance
Adjusting notification profiles for individual chats helps you focus on important conversations without constant alerts. You can limit media auto-download over mobile data to control bandwidth usage.
Storage settings show how much space conversations and media occupy, and you can review large files to delete what you no longer need. Regular cache clearing and database checks help the app run smoothly on older devices.
