N73 hangs/works too slow

U can virus scan for ur memory card or update ur mobile phone via nokia software updater.

My N73 M phone hangs, sometimes doesn't ring and takes 15-20 secs to navigate between functions. Pls help with a solution.

i have already reset the phone by using the *#7370# code, but it still remains the same....

Help me with a solution.....

Try to delete some themes from your nokia n 73

try reset the phone by *#7370#

make sure before resetting the phone you need to copy all your data and contacts from phone memory to memory card.
