I use one because it had one in the box. Otherwise, I would’ve purchased one since the back is prone to scratches and degradation. It also adds a level of protection to the phone.

If you care about these things best would be to use a chat application like Jami which won’t end up like WhatsApp.

Interesting such a feature exists in voyager. If I hadn’t seen this post I never would’ve found it even if I used voyager for years.

Where do you enable this setting?
