Massive problems with calls

Since we are not seeing widespread reports of this and there are a lot of GrapheneOS users in Germany I wonder what is different about your circumstances.
Have you removed permissions from or disabled any system apps? Have you made any changes to your phone via adb? Any other unusual/invasive changes you have made, like changing dev options, rooting ?

Carlos-Anso no to all of the above. I'm at a loss myself because it just started happening. I'm currently abroad and perhaps there are some problems with the connection, so I'll report back when I'm back in my country of residence.

luddevig I reinstalled my Salto Homelok (because I need to be able to lock my door), and the problem reemerged.

This is unexpected. Had a quick look at that app and the only thing that appeared possibly relevant is its Bluetooth capabilities. Did you have these problems when at a different location to your locks? Maybe some weird bug where the locks could be acting as the mic when you are on a call?

Can see the app has very few reviews on Play Store and looking at them looks to have had problems.

MichaelJohn to me it happened also abroad (Portugal). I landed today in Germany and so far (2 calls) the issue didn't reoccur. Just out of curiosity:

are you directly with Vodafone (I use Wetell and theyre on Vodafone)?
And was VoLTE in the country you have been supported by Vodafone (in Portugal my calls were on 2G)?

ZoraIsHere you may have discovered powder, since I am Also in Portugal and I'm having the problem here.

What is hilarious is that the SIM card that is giving me issues is Vodafone Portugal... I went to Vodafone and they couldn't identify any problems on their end, so I assumed the issue was related to GrapheneOS.

Now I'm at stake zero again.

I had the same exact problem on and off for over a year now. I switched my main phone for receiving SIM based calls to my iPhone and literally 0 problems. It was something to do with either the google pixel hardware or the graphene software, because the exact same SIM in the exact same location in an iPhone had no issue.

Seems like google needs to get their crap together. Between my fingerprint reader working about 25% of the time and not being able to use my phone for :: PHONE CALLS :: is ridiculous for a >$700 handset

MichaelJohn Do you still have the issue? I was in back in Germany for 2w and now I'm back in Portugal and so far had no issues with Vodafone in Roaming regarding call drops etc. I only have huge problems with call quality which I already posted here but from what I understood your issues are not regarding quality, they are regarding the call drops or it doesn't even ring.

hi eagle_owl. just joined dont have a sim yet. with australian carriers as you say not providing privacy & the likes of tangerine leaking info on the dark web do you have any advice for esim or sim. i dont have a problem with anyone phone tampering physically but there are reasons to want as much privacy & unhackability as possible. any advice in any area of privacy is appreciated.
