Hello. Plan to reset my phone. I know got setting to backup chat
setting>chat>chat backup
but normally if backup using this setting, it's would backup include picture, and it would take 1-2days. And when it's finish, there would got plenty of new message not backup. Is there any option to backup only chat history.

u can try More >> Export chat
that will saved the chat as text file.
no pics.

Its OK, I found a way. 1st, backup picture into PC, then delete all picture in whatsapps media and backup chat using whatsapps function. This way, whatsapps would detect 0 picture and only backup chat. I try and reduce from 3.8gb backup into 300mb backup only. Only take 10 minutes to upload, compare before take 1-2 day to upload. I dunno why take too long.

So I close this thread
