Hi everyone I'm using a Google 8a phone I just downloaded the graphene software, but am running into some issues where my sim card keeps losing signal . I was using prtonvpn and have to turn it off to just use the phone. I'm very new to this any kind advice be much appreciated. I have it on 5g also my notifications don't come through I have to open signal to see my messages. Please if someone can help me with this be much appreciated
