If you have deleted on your Samsung Galaxy S6 within Whatsapp an older message by mistake, which want to again have her necessarily, then you're lucky. At least then, if the time clock is 4.00 in the morning not yet passed after deleting. Why 4.00 clock in the morning?
The app WhatsApp automatically created once a day at night at 4:00 clock a backup. Here, the previous backup will be deleted and replaced by the current.
To import this backup and restore the deleted message by mistake, goes as follows:
Uninstalled on your Samsung Galaxy S6 the app "WhatsApp". Should you be asked whether news or databases you want to delete, select "No". It is just the app WhatsApp will be deleted.
Installs then WhatsApp again from the Google Play store:
If your WhatsApp now open, then you will be asked if you wish to restore the existing chat history. Confirmed with "yes".
FYI: All the news did you get in the morning until now of 4.00 clock, are deleted! Thus, this procedure makes sense only if the deleted message to restore is older than 24 hours.
Your WhatsApp course is now restored and your old WhatsApp message should appear again.
We hope that this guide has helped you to get an important message in WhatsApp again.
