Some transceivers are observed to suffer from intermittent
'Auto turn off'.
Symptoms of this can be following:
1. Phone switches off by itself
- Even with 3 or 4 battery bars and after turn on again it is possible
to make a call for a longer period
- Typically it fails repeatedly with intervals of anything from minutes
to one or two days
- This should not be mixed up with the normal Battery Low turn off
2. Phone gets stuck
- Keyboard not active
The following components should be changed in phones suffering from
that 'Auto power off' symptom:
