> 1. The Zoom slider: You can't select the different lenses easily (I'd need to set the zoom slider to exactly 5x to get the zoom lens without digital zoom, which is not that easy) and there is no way to quickly reset it to 1x. I also think the position for this slider would be better at the bottom (where most other camera apps put it)

That's not what the zoom buttons do in Pixel Camera and it doesn't switch at exactly the telephoto magnification zoom value but rather adjusts when it switches based on the available light because the telephoto camera can't handle low light as well. We could add 1x for going back to 1x but you can already easily zoom out to the ultrawide and the telephoto is more complex than people realize. You can see it often doesn't actually switch at the minimum.

> 2. The brightness and zoom slider are rather hard to hit, I maybe have a bit too fat fingers for these? (The brightness slider also does not seem to work in night mode) I also can't see the zoom/brightness values while sliding and the Google Camera App allows for more smoother/finer control. > > Same with the little arrow in the top left corner, it always takes like 3-5 hits to open the menu. Never had this issue in the Google Camera App.

You can swipe down for settings and can swipe left/right between modes. The arrow is mostly to imply that you can swipe down. We do plan to change the overall layout and sliders/buttons a bit.

> 3. I need to use the QR Code mode to scan qr codes. I did bind the Google Camera app to double click the power button so I can easily take pictures and scan QR Codes, without the need to tap anything else. But It's definitely a cool feature that the GrapheneOS camera can scan many more Code Types and also that the GrapheneOS Camera removes exif data by default

You can open it via the standard Android QR scan quick setting if you use it a lot.

> 4. The mode slider at the bottom doesn't let me scroll further than one mode, this means I'd need to swipe thrice to get to the QR Code mode from the Video mode (or tap twice) because when in QR Code mode I can't see the Video mode and vice versa

We can consider adjusting changing modes.

> 5. I currently tested it out for writing this comment and my phone definitely got way warmer than when using the Google Camera App. And it used 5% Battery while being active for 7 minutes. EDIT: very weird it did now vanish from the Battery Usage list in the Settings, and in the App Info it also says it did not use any battery since the last full charge (It did before)

It shouldn't consume more power than Pixel Camera. Don't know why that would be the case. It does do things a fair bit differently. CameraX is improving which brings improvements to our app without us having to do much and we implemented some things ourselves like the parallelized image saving in the background.

> 6. I think it does not support the Astrophotgraphy (Tripod) mode for the Night Mode.

We'd need them to add this to the extension API.
