Hello and welcome to Apple Support Communities, samorjuela,
We understand you've noticed that your camera is switching between the 3 different lenses. We'd be happy to help you troubleshoot.
Try the steps suggested here:
If the camera or flash on your iPhone, iPad, or iPod touch isn't working - Apple Support
1. If the photo is blurry, clean the front and back camera lenses with a microfiber cloth. If you see dirt or debris inside the lens or if the camera lens appears to be misaligned or blocked, contact Apple Support to discuss service options.
2. Restart your iPhone, iPad, or iPod touch.
3. Test the camera again by taking a photo. If your device has a front and rear camera, check if one or both isn’t working. To switch cameras, tap the rotate button

Let us know the results.
Have a great day!
