First I have to say that I'm really impressed with the work that have been done on GrapheneOS. I've installed it on a Pixel 4a 5G and had a couple of issues.
First, I never got connected to 5G network only LTE, my phone subscription and the location where I live both support it, so as the phone model. I've checked on the settings but everythigs looks good. Any clue on this ?
Second, while I'm connected the network get lost at random time. I can be in a middle of a Signal call or watching a video and bim, suddently the all connection are lost for around 5 seconds. This happend many times a day and that's pretty anoying, what is causing that ?
Thanks for you help :)
