Phone has become slow / hangs

Old phone or new, these steps help speed up almost every Android phone.

Steps

  1. Restart the phone
    Simple but powerful — restarting once a week clears the memory that causes hangs.
  2. Delete apps you don't need
    Uninstall apps you haven't opened in months (Settings > Apps). Fewer apps = faster phone.
  3. Speed up animations (Developer Options)
    Tap Build Number 7 times in Settings > About Phone, then set Window/Transition animation scale from 1x to 0.5x in Developer Options. The phone will instantly feel faster.
  4. Keep 20% of storage free
    When storage is 90%+ full, the phone hangs. Empty the gallery trash and move/delete old videos.
  5. Remove heavy launchers/themes
    Fancy launchers and live wallpapers eat RAM. Use a simple launcher and a static wallpaper.
  6. Factory reset: last resort
    If nothing works, first back up WhatsApp and your photos, then go to Settings > System > Reset > Factory Reset. It makes the phone feel like day one.
