I found a cheat to capture view once images/videos on Whatsapp. Instagram and Snapchat
I am about to share a trick which Whatsapp is gonna hate it and this thing can probably be never fixed, ever.
No use of GB or any mod apk. All you need is VM or simulator. In android, I am using Virtual Android app which acts like VMware for android. Just install it, install WhatsApp, log in or link it and then boom you go. So take screen shot or use screen recorder to capture those view once. This not only works for Whatsapp, but instagram, Snapchat or any possible app.
PS: The app crashes quite often on latest versions of android, so prefer using a screen recorder and open such msgs. Screenshot also works very fine without letting other person know about it. Also make sure to use screen recorder app from default phone, not install screen recorder in the VM and run from there xD, same for screen shot (prefer three finger screenshot).
Consider helping me with sme money if I just helped you with those night clicks ;)
