While the phone is powered on, and I plug something in the jack of the phone, I hear a continuous clicking sound, with the frequency of about 4 times per second, on the right speaker. The left speaker plays the audio as it should.
I don't have a mono device to see how it behaves with it...
The phone's speakers do not have this problem, or the Bluetooth headset.
The sound is identical, as far as I can tell, to the sound (almost?) any audio device makes when it's plugged in (and/or out?).
Phone: Lenovo A800
Android version: 4.0.4
The issue doesn't happen on my Nexus 7.
Happens with headsets, earphones, external speakers... Pretty much everything in the jack.
I chose to post the issue here because I have found various similar issues with other Android devices around the Internet, but no working solution.
Is there any known cause for this? Any solution..?
My brother just bought a new headset, and there's no clicking sound with it.
I looked at the jacks and there seems to be no difference.
