WhatsApp for Samsung Galaxy F55

Samsung's One UI ships with ads in some stock apps and pre-installed extras that many F55 owners dislike. Turn off recommendations by opening Settings > Privacy > Customization Service and switching it off, then open each Samsung app like Weather, Themes and the Galaxy Store, go into its settings and disable 'Marketing notifications' and 'Personalized ads.' For unwanted apps, long-press the icon and choose Uninstall, or disable system ones via Settings > Apps > tap the app > Disable. See how others solved this on Reddit

The F55 is a solid pick for a parent thanks to a bright flat AMOLED screen, clean readable One UI and long update support, though it lacks an official IP water-resistance rating so it is less forgiving of spills. To make it easier to use, go to Settings > Accessibility > Visibility enhancements to enlarge fonts and boost contrast, and turn on Settings > Display > Easy mode for larger icons and a simpler home layout. A protective case and screen protector are still worth adding for everyday durability. See how others solved this on Reddit

The F55 uses a Snapdragon 7 Gen 1 tuned for smooth everyday use alongside Samsung's longer software support, while the iQOO leans toward higher raw benchmark numbers; for daily apps and longevity the F55 holds up well. If the F55 ever feels sluggish, reduce background drain via Settings > Battery > Background usage limits, and speed up transitions by setting Animation scale to 0.5x in Settings > Developer options. Keep it current through Settings > Software update > Download and install. See how others solved this on Reddit

Many buyers worry Samsung mid-range phones are dropped quickly, but the F55 is covered for several years of OS and security updates, a key advantage over many rivals. Check your current status under Settings > Software update > Download and install, and enable 'Auto download over Wi-Fi' so updates arrive automatically. To see your patch level, go to Settings > About phone > Software information and look at the 'Android security update' field. See how others solved this on Reddit

The F55 has a large battery, but heavy screen-on time and background apps can still drain it faster than expected. Turn on Settings > Battery > Power saving, use 'Background usage limits' to put rarely-used apps to sleep, and lower the refresh rate via Settings > Display > Motion smoothness to Standard. For faster top-ups, make sure Settings > Battery > More battery settings > Fast charging is enabled and use a 45W-capable USB-PD charger, since the F55 supports up to 45W wired charging.
