The Pixel 6a will be supported by GrapheneOS in the near future. If you - want a cheaper device instead of a flagship, consider getting a Pixel 6a and - waiting for GrapheneOS support.
+The Pixel 6a is a budget device with the same 5 years of guaranteed full + security support from launch as the flagship 6th generation Pixels. It also + has the same flagship SoC as the higher end devices, the same main rear and + front cameras as the Pixel 5 and a rear wide angle lens matching the flagship + 6th generation Pixels. Compared to the 5th generation Pixels, it has 5 years + of full security support remaining instead of less than 2 years and the CPU is + 2x faster. We strongly recommend buying the Pixel 6a rather than trying to get + a deal with older generation devices. You'll be able to use the Pixel 6a much + longer before it needs to be replaced due to lack of support.
