Google Camera can take full advantage of the available cameras and image processing hardware as it can on the stock OS and does not require GSF or - sandboxed Google Play on GrapheneOS.

- -

On 7th generation Pixels, Google Camera is a privileged app on the stock - Pixel OS and has privileged access to Tensor SoC hardware acceleration - unavailable to regular apps. Since it's a regular sandboxed app on GrapheneOS, - it has to use more software processing. It captures photos just as quickly but - takes longer to process them after capturing. It doesn't lose any features or - any image quality from lack of privileged access. Since several photos can be - queued up for processing, this is only noticeable if you try to quickly take - multiple pictures without a couple seconds for it to process them. One special - case is Portrait mode on the Pixel 7 and Pixel 7 Pro which requires a lot of - time to process each picture without the privileged hardware acceleration and - is therefore very noticeable because after a few shots, you'll need to wait a - while for the slow software processing. Google has acknowledged this as an - issue and is working on improving it. There have been major improvements in - recent Google Camera releases. We're considering providing a toggle for users - to choose to give direct GXP hardware acceleration access to Google - Camera.

+ sandboxed Google Play on GrapheneOS. Direct TPU and GXP access by Google apps + including Google Camera is controlled by a toggle added by GrapheneOS and + doesn't provide them with any additional access to data. The toggle exists for + attack surface reduction. Every app can use the TPU and GXP via standard APIs + including the Android Neural Networks API and Camera2 API regardless.

We aim to reduce the benefits of Google Camera compared to GrapheneOS Camera over time, especially on Pixels. Many features of Google Camera will
