I`ve installed a lot of applications from standard repository. Now camera application doesn`t start. It crashes after 1 sec.

I restarted device, uninstalled a few of applications but with no result.

Need help!

First off if we knew what apps you'd installed and what the error message is (if any) we'd be able to give you a few pointers, but the ones that come to my mind immediately are BlessN900 and FCam.

If you've got those two installed remove them and try again.

Does it crash whichever way you launch it?

uhhh, could be your filesystem is corrupt, some people fixed the camera crash by letting windows run chkdsk on it when mounted in usb mass storage mode.

some people that removed and reinstalled fcamera for a similar problem ended up with endless reboot loops so i wouldn't try that first.
just read this

More information is needed as to what could be causing it. Are you using the overclock kernel? Installed Fcamera or anything else which uses the fcam drivers? Maybe they need to be updated.

There are a lot of things which can cause the app to crash.

try this
1. connect ur phone with pc
2. use Nokia Pc suit to connect ur phone.
3. check for update.
4. if ur phone is not updated.update ur phone.
5. if ur phone is full updated thn Reinstall all updates.
thanx...
