Open Camera app... in the auto mode try getting an object near the camera.. preferably your hand.. long press on the near object (hand) and lock the focus.. now you can click amazing macro shots.. check out my profile if you like macro photography.
Taking macro shot needs stable position. Get your camera closer to the object and tap to focus on object. Adjust your hand position and distance as per your choise.✌ Also you can tap and hold on the object to on continuous focus. It will help you to continuous focus on the object.📸
