I dislike notifications so have them pretty much turned off.

Not using any play services or g-mail. I use busybusy for work, it says I need the play service but it works without it. My credit Union app works fine. I never got into using my phone to pay, so haven’t tried that.

I had Calyxos and switched away from it also.
Really like the Grapheneos. Google pixels seem to be good hardware. I’m going to buy an extra 7,8,or 9 pixel. Not sure if newer pixels will stay as useable.

I’ve found some cheaper pixels on e-bay, bought mine there.

You could be right. I looked at several of them on eBay and could only find phones with the e-sim, couldn’t find any with sim card tray.

Some apps require google play, like android auto and maps.
I’m using grapheneos with open street maps, so I don’t think there would be any problem with that. There is a work around to load some apps that require google play with out a google account. I’m guessing that is what would be affected.

Grapheneos has a wonderful how to install procedure. I did it with a Linux Debian machine. It took several tries to get the bootloader right, part of that was I didn’t know what I was looking for. Once your phone has the red triangle in the bootloader of the phone, the installer should recognize it, and the installer was awesome from there.

10 does not have a sim card tray, the 9’s do. First post with grapheneos on a new to me 9 I was able to get!
