+## UPC-A vs EAN-13 codes
+
+UPC-A is a special case to handle if you need to cater for it. Android's SDK officially supports UPC-A but iOS does not, instead they handle the code as EAN-13. Since EAN-13 is a superset of UPC-A, with an extra 0 digit at the front.
+
+This means, the `upc-a` types are reported under the `ean-13` umbrella type on iOS:
+
+```jsx
+const codeScanner = useCodeScanner({
+  codeTypes: ['upc-a'], // <-- ✅ We configure for 'upc-a' types
+  onCodeScanned: (codes) => {
+    for (const code of codes) {
+      console.log(code.type); // <-- ❌ On iOS, we receive 'ean-13'
+    }
+  }
+})
+```
+
+You will need to keep this in mind and do the conversion from EAN-13 to UPC-A yourself. This can be done by removing the front `0` digit from the code to get a UPC-A code.

   * 720p Photos, 720p Videos, 30 FPS (smaller buffers/e.g. faster face detection)
 * Each app has different requirements, so the format filtering is up to you.
+* The `videoResolution` and `videoAspectRatio` options also affect the preview, as preview is also running in the video stream.
 
 To get all available formats, simply use the `CameraDevice`'s [`formats` property](/docs/api/interfaces/CameraDevice#formats).  These are a [CameraFormat's](/docs/api/interfaces/CameraDeviceFormat) props:
 
 - [`photoHeight`](/docs/api/interfaces/CameraDeviceFormat#photoheight)/[`photoWidth`](/docs/api/interfaces/CameraDeviceFormat#photoWidth): The resolution that will be used for taking photos. Choose a format with your desired resolution.
-- [`videoHeight`](/docs/api/interfaces/CameraDeviceFormat#videoheight)/[`videoWidth`](/docs/api/interfaces/CameraDeviceFormat#videoWidth): The resolution that will be used for recording videos. Choose a format with your desired resolution.
-- [`minFps`](/docs/api/interfaces/CameraDeviceFormat#minfps)/[`maxFps`](/docs/api/interfaces/CameraDeviceFormat#maxfps): A range of possible values for the `fps` property. For example, if your format has `minFps: 1` and `maxFps: 60`, you can either use `fps={30}`, `fps={60}` or any other value in between for recording videos.
+- [`videoHeight`](/docs/api/interfaces/CameraDeviceFormat#videoheight)/[`videoWidth`](/docs/api/interfaces/CameraDeviceFormat#videoWidth): The resolution that will be used for recording videos and streaming into frame processors. This also affects the preview's aspect ratio. Choose a format with your desired resolution.

 - [`videoStabilizationModes`](/docs/api/interfaces/CameraDeviceFormat#videostabilizationmodes): All supported Video Stabilization Modes, digital and optical. If this specific format contains your desired [`VideoStabilizationMode`](/docs/api/#videostabilizationmode), you can pass it to your `<Camera>` via the [`videoStabilizationMode` property](/docs/api/interfaces/CameraProps#videoStabilizationMode).
