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