Hello,
same problem for me:
- Sound is OK through jack but after some time I can only hear crackles for around 10 seconds, and then, nothing. Tried 3 different jack earphones: same result. Tried different apps: same result.
- When this occurs, only a reboot solves it
- When this occurs, sound is OK through Bluetooth and on speaker
- I experienced this problem 3 times this morning, on my bicycle, the phone being in my pocket. Even though I am not a mad max on the road, the movements of the phone in the pocket may be the cause of the problem
- I did mention the problem to the online customer support
As the problem disappears after reboot, it might be a software issue.
Some other discussions about audio problems on FP2 and FP3 seem to indicate it is a software issue:
If so, a device replacement won’t be very helpful.
We would then have to wait for an OS update from Fairphone, or install another OS.
