Most (or all) photo apps have settings.
The phone I currently have is a Huawei and to bring up the settings (in the stock photo app) I swipe left and there is basic settings such as resolution and where to save the image and so on.
Some other apps may have a settings button, generally it looks like a sprocket or the "hamburger".
With the resolution setting you set how large the image will be saved as.
How the camera/phone does the downsampling may be differernt.
