How to identify the Whatsapp sender of a media while playing it from the gallery? When media are received through Whatsapp groups and contacts, they are stored in the storage and are available for the media scanner to list them. When I view Whatsapp videos folder in MXPlayer I see the videos that I received through Whatsapp.

Occasionally when I see such an interesting video or image I forward to some people or group, but later to realize that I received it through them. This strikes only when I open the chat history to see the same media sent by someone else?

Question:
In this situation I want to find out the sender (or the group) without opening and scanning the Whatsapp messages to avoid this embarrassment.   I guess the file naming convention only helps to find the date and time.
You can take a look at media's metadata. If the sender's name is there you can identify it that way. Otherwise you can ask WhatsApp developers to add sender's name into the title or something. Or if you want you can manually sort the files.

It's all up to the app.
