I've been using open camera on android since 2019.
It's far superior to anything I've seen natively installed on any device. It has a lot of options, which I suspect can be confusing to some, but they're worth familiarizing with.
My favorite feature is the macro, which when coupled with the right UI settings produces photos that when I have printed, result in the person saying "wow! You took that with a phone!?". And I say "yeah. Open Camera. It's great, try it sometime".
Highly recommend.
Is it really as good as Google Camera at computational photography; noise reduction, night mode, deblurring, stacking, etc.? That would be very impressive.
What phone do you have?
I havent tried Open Camera in a while, but my conclusion is that the phone's camera app is best.
