WhatsApp / Signal
I can see how Signal would be safe, you can't screenshot it and it seems to have some pretty robust protection around the app...however, if a phone has been locally compromised (which appears to be the point of these 'sploits) then WhatsApp could easily be compromised since you can screenshot it.
Also, WhatsApp images are stored in the clear on your phone.
Am I right?
