Uncaught exception: java lang. null pointe exception

Help! My 8230, when i turn it on, will read the error message " uncaught exception:java.lang.NullPointerException. .Since it started doing this it will drop calls or sometimes won't ring at all. When there is an incoming call, it will just show the blue phone symbol on the front, but won't ring even though it is set on loud. Any ideas? Thanks.

Hi and Welcome to the Forums!

Anytime random strange behaviors creep in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.


Failing that, you should check with your carrier about an updated device OS....
