I'd pick 'Use system settings' - users often have a preference set for accessibility reasons, and it's a more seamless experience.

I'd pick Light mode for better readability, think it's more important for users to easily navigate the app. What kind of app are you building?

We tried using system settings and users kept complaining about having to change it manually, so ended up forcing dark mode by default. Curious to hear your thoughts on eye comfort vs readability.

I'd pick 'Use system settings' - users often have a preferred mode set for their whole device, so it makes sense to respect that. What about testing user engagement with A/B testing for your specific app?

Dark mode for eye comfort is my go-to, but I've heard some users struggle with it in low-light environments. Have you considered gathering user feedback through surveys or focus groups to inform your decision?
