I would suppose that, depending on the type of phone you have, there may be more than one choice of apps. When I found my 'new' app, it was as simple as going to the Google Play Store and, instead of looking for a game, I typed in 'camera app.'
There were quite a few choices, so I checked for a more recent app and also the rating given by other users. (The HD camera app that I downloaded is a 2023 version and rated 4.8)
