Accidentally deleted or lost your WhatsApp Messenger chats? Don’t worry, it’s pretty simple to get back your chat history on your phone.WhatsApp automatically makes daily backups of your data and stores them on your phone. You can recover the most recent backup by uninstalling and reinstalling the application. Here’s how it’s done:
Uninstall WhatsApp from your Android phone. You can do this by searching for the WhatsApp Messenger page
Restore your history After the installation process WhatsApp will ask you “would you like to restore your message history from backup?” Tap 'Restore' and wait while your chats are recovered.
Recovering from older backups
If the chat you want still isn’t there you could try restoring from an older WhatsApp backup. Backups are kept for the last seven days on your memory card. To do this, you first need to find the backup file and rename it. Install an file manager app such as https://play.google.com/store/apps/details?id=com.metago.astro" target="_blank" rel="nofollow">ASTRO File Manager and find the WhatsApp backups folder. It will be saved here:/sdcard/WhatsApp/Database.
Rename the backup file
Find the backup file for the date you last remember having the conversation saved (within the last seven days, remember) and rename it from “msgstore-YYYY-MM-DD.1.db.crypt” to “msgstore.db.crypt”, using your file management app.
Once you’ve done this go back to step one (i.e. reinstall WhatsApp) and it will restore your chat history based on the backup version you specified
