Long day (nearly 5 hrs.) flying. Early in the am. PIC tired.2. Low ceiling and marginal VFR conditions at night adding to mental load.3. Handheld moving map crashed and was unable to use. Was attempting to troubleshoot.4. Too hasty correction of heading potentially causing a collision.5. I know the area very well and took that for granted.

Title: C172 pilot arriving SMO at night in marginal VFR conditions; experiences a failure of his moving map display. This results in inadvertent entry into LAX Class B when the wrong freeway is chosen as the route to SMO. When the error is detected the hard turn away results in an airborne conflict with a helicopter.
