6. Common problems and fixes
Dark mode is generally stable, but a few common issues can crop up. Here is how to resolve them.
| Problem | Cause | Solution |
|---|---|---|
| Dark mode turns off by itself | Automatic scheduling is active | Check Settings → Display → Schedule. Disable the schedule if you want dark mode always on. |
| Some apps stay light | The app does not support the system dark theme | Check the app’s internal settings. On Android, try Developer Options → Force Dark Mode. |
| Text hard to read | Insufficient contrast in certain apps | Increase brightness, or disable dark mode in that specific app only. |
| Screenshots look dark | Normal: they capture the active theme | Not a problem. If sharing, temporarily disable dark mode before taking the screenshot. |
7. Frequently asked questions — dark mode smartphone 2026
Does dark mode really save battery?
Yes, but only on OLED and AMOLED screens (where black pixels are literally switched off). According to tests cited by Android.com, dark mode can reduce screen power consumption by up to 30% at high brightness. On LCD screens the savings are negligible because the backlight stays on regardless of pixel colour.
Can I use dark mode in only some apps?
Yes. Many apps — including WhatsApp, Telegram, YouTube and Chrome — have their own independent theme setting. You can keep the OS in light mode and turn on dark mode only in the apps you prefer, or the other way round. Telegram even offers five different dark themes to choose from.
Is dark mode better for your eyes?
In low-light environments and at night, dark mode reduces eye strain because it emits less total light. In bright sunlight, however, a light background with dark text is actually easier to read. The recommendation is to use automatic scheduling (light by day, dark at night) for the best comfort. For more details see Apple’s guidance on display settings and visual health.
How do I force dark mode on apps that do not support it?
On Android you can unlock Developer Options (tap “Build number” seven times in About Phone), then go to Developer Options → “Force Dark Mode”. This attempts to apply the dark theme to every app, even those not optimised for it. Be aware that some apps may show graphical glitches with this option enabled. On iPhone there is no equivalent override.
Does dark mode also apply to the Home Screen wallpaper?
On Android, the wallpaper does not change automatically, but you can pick a dark wallpaper from the system gallery. On iPhone with iOS 18, the wallpaper can adapt automatically: go to Settings → Wallpaper and enable the dark version for compatible wallpapers. Icons and widgets adjust automatically to the selected theme thanks to Material You on Android and iOS 18 customisation options.

You now know exactly how to enable dark mode smartphone 2026 on any Android or iPhone, how to configure automatic scheduling and how to manage individual apps.
