I have just replaced the bottom module of my FP3. Before the replacement, vibrator and speakers worked. After the replacement, the phone works excellently, expect vibrator and speaker output is nil. Can anyone suggest what might have gone wrong?
I suppose it is possible the replacement bottom module was dead on arrival, or something got damaged in the replacement, but it would seem more likely that the connection to the bottom module is not quite made properly. Have you tried unplugging the connector and reseating it?
