Yeah, what my subject line says.
I've downloaded a theme and I noticed that it slows the phone down when I go to the menu page or the homescreen etc. So how do I uninstall a theme?

First, if dont want theme you can go to setting=>themes=>and just change it back to default Nokia Themes. But if you want to delete it permanently, go to settings=>application manager=>Installed apps, then look your theme there , press options and delete it.

did you get sorted. not in applications. how do you uninstall themes?

Guys I GOT THIS WEIRD QUESTION .. i had downloaded the JOKER THEME... installed it.. but i remember it sayng it wont b compatible with the phone still i installed it... now wen i changed it to the default theme (the black 1) i still can c the fade joker n the screen things written even though i uninstalled the THEME from the installed application folder.what do i do now ?

The other default blue n white themes r not creating this issue of the faded joker theme.

Sorry to say you only option to completely sort thios issue is a Hard reset (*#7370#) which will format your C: drive so back up before hand. The best option is uninstall everything first the Hard Reset and Format yuor E: drive as I assume you have apps installed there too. This will completely clean yuor phone. Then only restore Contacts, Callendar. Do not restore settings as this could re-introduce issues. Files should only be restored if you really need some Notes back, otherwise do not restore this either as this could also re-introduce some files you don't want.
