Since I saw no one post this problem recently,might as well.
This problem happened on my phone,where I was trying to watch a stream,and it suddenly froze along with my phone and my phone automatically restarted by itself.
I tried everything from deleting caches,restarting my phone,my data,even turned off battery saver in the settings. Nothing works,until I updated from play store.
It was only one time success,but when I entered the stream again after an hour,the problem occurred again. I thought the update fixed the problem..but no,it didn't.
I'm quite sure my phone couldn't be the problem,as it was fine before until today. I still can join vc,but not stream...
Edit: I tried to reinstall discord,and still didn't work. I figured it might have something to do with my storage space available(even though I have plenty) and uninstalled a 2gb game; and I was able to watch stream again BUT my mic was not transmitting my voice,and when I tried to rejoin call so I could speak,the problem happened again,froze and restarting my phone. App permissions are on Accept,so not about that.
I've sent a debug log(?) if that would help.
