php Xiaobian Yuzai has simplified the steps for using a level on the iOS 12 system. First, open the Compass app. Swipe right on the compass page and a level will appear. Next, place the iPhone flat on the object that needs to be calibrated, and make sure the level shows green, which means the object is level. If it is not horizontal, you can calibrate it by fine-tuning the iPhone. Finally, once calibration is complete, you can enjoy the convenient function of level measurement.
