I've had this issue for a while and assumed it was something based on my location when making a call, but with quarantining I have found this is not the case. I have a Samsung A20 with Boost Mobile.
My issue is that when I call a phone number (any number, even when dialing manually) there is a chance that the call will "hang" on my end, but still go through to the other caller. What I receive is silence; the sounds of the phone say it's placing a call, but there is no simulated ringing sound or sound from the other side. I've let it just sit waiting to make the second "beep" to signal it's ringing, and have gone up to a minute with nothing on my end. The recipient actually does get a call though, and answers to no sound either - not hearing me, though the call looks normal on their end. I have to hang up and call again, which usually puts it through as normal would be - I've only had it twice continue to do the "silent hanging call" for the second time.
Has anyone else experienced this, and if so did you find a solution? In trying to fix it, I have changed my calling app from the default caller app to Drupe, but again this continues to happen telling me this is within the phone hardware. Any advice is much appreciated! Thank you!!
