This was partially available earlier but was meant for the un-downloaded media files for 30 days. Previously, when you received an image, GIF, video, document or voice message sent on WhatsApp and deleted the file in the WhatsApp folder, then users couldn't download it again, reported Gizbot. If a user ended up deleting the content from the WhatsApp folder after downloading, there was no option to go back to the conversation and redownload the content after the expiration of the validity.
Recently, WhatsApp has modified this behavior: "when a media is successfully downloaded, WhatsApp doesn't delete it from the server, allowing the users to download it again if the file was accidentally deleted in the path where WhatsApp saves media", said WABetaInfo. Due to a mysterious bug, the timestamp on the chat window of users is appearing with numbers.
WhatsApp has rolled out a new feature wherein users will be able to re-download the files that were deleted from the phone. Otherwise, it will not be possible to redownload it. But this is not the case now, as the app lets you download deleted media from its servers with the latest update. When you download the files, the same was deleted from the servers. Rolling out the "WhatsApp Payment" feature will prove to be a game changer for Facebook owned messaging app. It took several trials to download the files deleted 3 months ago.
In a related development, WhatsApp is testing a new feature which would allow users to customize the shape and size of the WhatsApp icon on the home screen. Extremely old stuff from August 2017 wasn't accessible at all, with WhatsApp simply asking them to request the sender to forward the media again.
WhatsApp on Android will let users re-download old images and videos that might have been deleted from the user's mobile storage.
