No sound during calls - Elephone P9000 Questions & Answers

Hi there,
I've got a problem since the last update (20160608): I cannot hear anything in calls no matter if I am called or if I call someone. When I use the headset or switch to loudspeaker everything works fine. The problem exists with several SIM cards. I tried rebooting, clearing cash of Google Playstore, Google Framework and Play Services. And I changed the volume to maximum of course.
Any idea how to fix that?
Thanks a lot for the support!

Well since it worked before the update it most likely is not a hardware defect. I guess the usual suggestion/solution would be a factory reset, or to re-flash the ROM, but before you do something like that you could give the following a try:
- go into EngineerMode by dialing *#*#3646633#*#*
- go to the tab "Hardware Testing", then Audio>Volume>Voice and select "Receiver" in the second field
- compare/change the values to these:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If your values do not differ from the ones shown, try to slightly change one of them and press "Set". Maybe this triggers a reset of the Receiver. Also turn the phone off and on again afterwards.
If this doesn't work, and if you don't find another solution, you should probably do a factory reset. Good luck!

Thanks for your help
Hello and thank you for your help.
However my values are the same as in the picture. Changing them and pressing set did not change a thing. This morning the fingerprint also broke. It does not recognize any finger and I am unable to set a new one. The sensor simply does not do anything. Turning on and off, rebooting did not help. I will try flashing Eragon and if it does not help I will try the tomrepair service. Any experiences with them?
Thank you

I have that same problems fingerprint scanner and phone calls. No one can hear me. I have to put it on speaker for a few seconds then turn it off. Even then. People still say they can't hear me. But this is on telephone c1 max.

I have the exact same problem with the ear-speaker.
Music one on the bottom works fine, so does bluetooth headset.
No sound during calls, others can hear me though.
I tried reseting the phone also.
I'm on the new Android 7.1 firmware. (http://bbs.elephone.hk/thread-13393-1-1.html#.WUmUEGT1-SF)
I can't try the audio testing trick since a small part of my screen is not working either and of course it's exactly the the first item of the screen i can't select. I mostly managed by rotating the phone but test-tool does not allow rotation :S
I ended up getting mad and went out and got myself a new mobile (Not Elephone).
I loved the phone, but build quality is seriously lacking. Then again, it's priced accordingly.
I'm willing to test stuff if anyone has new ideas.

Same problem here, I have touchscreen problems (top of screen), audio call's problems and since last update of september, network settings problems (I must reboot my phone to take change of network state otherwise it restore his value after 2-3 min) and sim tray slot 1 doesnt work (must use slot 2)
I love the phone but the quality is not so good as other marks.

I also encountered the issue with the low sound in the voice call i tried to set the values that the picture showed and there is a small difference. Also any suggest to go higher with the values posted in the picture and what is the formula for increased in voice calls volume?
