For the past two weeks my BB curve 8530 , has been really slow. it will be black screen until i press the track pad a bunch of times. Trying to send sms is brutal ill type what i need to , then have to wait 30-45seconds before the words show up. going around the menus is choppy and slow, and it seems everyday for about 3 hours my letters will mean some thing else (ex:i would hit E and K would come out ) and my O button would not work at all. I have no extra apps on my phone , and internet is blocked, for app memory i have 95.5mb free and on my media card i have 3.1gb free. Does anyone have a answer as to what is wrong ?

Did it get wet or dropped?

Have you tried a battery pull- with the device on, take the battery out for 30 to 60 seconds, put it back and let it reboot.

just take the back up and formatt the device........

if agian same problem arise,then its a device problem.....
