Yeah but not by Google so the security isn't the best because they don't allow GrapheneOS to update certain hardware parts
4a still better than Pixel 9, can't even get a headphone jack with the Pixel 9, straight in the garbage can with it

The 4a had the best form factor and I definitly miss the headphone jack. The 9 is ugly as hell btw. I would only buy if it was the only option to run graphene.
