Since yesterday I have no sound during calls. When I receive a call, the phone rings, when I answer a call, the call connects, but it is silent. Neither party can hear anything. When I try to make a call, the call connects without dialing sound, and again neither party can hear each other.
I have tried the following:
rebooted the phone
emptied the cache of the default dialer app
used a different dialer app
checked that the carrier services app has all permissions
Since both dialer apps had the same issue, I assume that the problem lies deeper somewhere.
What is the cause of this and how can I fix it? I’ve been using this phone for 10 days and other than that it works fine. Earlier even phone calls worked as they should.
This is quite serious, as it prevents me from using my phone… as phone.
All of this works. Now I was about to submit a support request, so I turned off my phone and took out the battery to look for the IMEI. After I took out the battery I remembered that I should look for the IMEI in the settings. When I turned the phone on again, calls worked again. At least for now.
tldr: Taking out the battery for a few moments while the phone is powered off might solve this issue.
We had the same problem and found out that it formerly occured always after the Amazon music app had been started (but remained after deinstalled) or after using the podcast app Antenna Pod. Perhaps you could try to uninstall/block similar apps that use sound?
We blocked Amazon music by the family app and in the meantime for the last two weeks phone calls were no problem. Would be good to get informed when the problem with the Amazon music app had been solved.
I am also having this problem (again) since yesterday. Very annoying when people cannot reach you when you are available.
There were no music apps open when people tried to call me.
Because I do not have the option to turn off 4G LTE, I have also tried to turn off 4G completely because I didn’t have problems when this was turned off to temporally solve the unknown caller problem. Unfortunately, it didn’t work. So 4G settings are not the cause of the problem.
