Abnormal call interruptions and random cellular network disconnections

Hello Everyone,

as suggested by a moderator, I’m opening this topic to try and find out if what I’m experiencing is limited to my phone or is a diffused issue.

I bought a month ago a new FP6+ from the official store, I live in Italy and I’m using it with an Iliad sim card.

My issue is that, if make long calls, the phone usually ends calls automatically without any action from me.

I usually make calls using Sony Bluetooth earbuds, so I’m not touching the screen and I’m stationary at my desk while calling.

I noted that disabling “4G calls” toggle (I think is VoLTE), the issue appears way less often.

I also tried disabling VoNR from developer options, but it doesn’t seem to make much difference.

I also noted that sometimes the phone randomly loosed signal totally, even when signal was stable and the phone was laying on the desk, for about 20 seconds to then return to normal operation.

Also this issue practically disappeared after disabling the VoLTE option mentioned before.

My current OS version is: FP6.QREL.16.115.0

I already tried resetting mobile network settings, but nothing changed.

Has anyone faced this kind of issues?

Yes, I have the same issue in Sweden for a while now. My phone is usually on speaker with the screen off. I’ve been in contact with Fairphone support team but they have not been able to solve it. Latest version of Android.

I also have this problem in the UK. Phone randomly hangs up midway through a call. At first I wondered if my ear was accidentally pressing something on the screen, but it still happens if I’m on speaker phone and not touching the phone at all.
