Android 10 only?
Whatsapp does really need a full dark mode with green or red text to preserve AMOLED devices. I have an S8 I bought in August and it has very slight almost unnoticeable burn in from the call and video call buttons. When I put various colors on the screen, there is no issue until I put blue where I can see traces of Whatsapp. This in not a defect but rather something that will happen normally if you keep a static image too long on the screen.It's lovely. WhatsApp needs to hurry up.
