I'm having the same problem with my 88xx. It goes crazy on me from time to time. Last night it sent a text message to the same person every minute. Super embarassing. I was gonna try to clean it.. but I guess that wont work either. Helllp Ussss !
How was it sending a message to the same person every minute, was it in a holster, laying on a table, in pocket?
There are good pictures and instructions on removing the trackball to clean, but that won't fix something that sends over and over and over again. Much more than a simple press of the trackball is required to send an SMS.
Well when I fell asleep it was in the SMS and MMS screen so it would hit reply and send on its own. I have it locked now.. but when I enter the menu it'll go crazy from time to time. Its like the buttons are stuck. This happens randomly.. then it'll work perfect again.
