Hi,
First of all, thanks everyone for the great work on GrapheneOS and all the community for the support.
I have some issue with the mobile data that I am unable to troubleshoot.
Very often (often enough to be an issue using the phone) I loose the mobile data connection. This is not related to signal strength of the mobile network, as the same behavior is reproduced independent of this.
I just lose mobile Internet, and see the exclamation mark next to the signal indicator. Sometimes, I do also loose for brief moments complete signal but most of the time there is full mobile signal when this happens.
This is happening with a downloaded SIM card. I used the card on 5G and then moved it to LTE, just to see if it works but the behavior is the same.
I am also using Netguard VPN, as a firewall on the phone. I have disabled Netguard to see if the issue is resolved, but it looks like this is not the issue.
Sometimes it may help to stop and start the mobile data or put the plane in airplane mode and back, but it also may be just a coincidence.
If I do not do anything, it will come back at some point, but it is happening so often that the preferred mode of using the phone is WiFi and it makes very unreliable to use the mobile data.
The phone is a Pixel 7 Pro running build number TQ2A.230305.008.C1.20230326
Any help in debugging this would be much appreciated.
