Nokia N8 is not the fastest smartphone on the market, but you can use some tips and tricks I'm using in order to boost it.

1. Don't use wallpapers on home screens.
2. When not using wifi, disable wifi search.
3. Disable/uninstall programs that autostart. You can do that using M-Guard
4. Disable programs that run in background. That will slow down your N8 and it will drain your battery.
5. Clear the browser cache memory
6. Update your firmware. Nokia always improve their OS from time to time.
7. For faster Homescreen response times, disable Themes Effects
Go to the MENU - SETTINGS - THEMES - GENERAL
Click below on OPTIONS - THEME EFFECTS and select OFF)
