Do you have an iPhone and want to learn how to calibrate the screen? You have to, first of all, understand this. Even though you can calibrate the motion sensors and the screen brightness, you can’t calibrate the sensitivity of the iPhone touch screen.
How to Calibrate the Motion Sensors
Do you know that your iPhone’s motion sensors can be affected by close proximity to a magnet or by environmental factors? If you didn’t know this, then know that it’s possible. If this is the case, the iPhone notifies you to use the iPhone’s Compass app. You can use the app to recalibrate all the motion sensors, including the gyro, magnetometer and accelerometer.
To do this, use the following steps:
- Click on the Compass app on the iPhone screen.
- Go through with the on-screen prompts to tilt the iPhone screen and roll the red ball around the circle.
- Continue to tilt the iPhone until a compass is displayed on the screen. When the compass is displayed, the motion sensors are calibrated.
How to Adjust the Brightness
To adjust the brightness of your iPhone’s display in the Setting app:
- Start by clicking on the Settings icon on the iPhone.
- Click on Display & Brightness
- Then move the slider at the top of the Display & Brightness screen from left to right. Do this until you reach your preferred level of brightness.
Note that if you turn on Auto-Brightness in the Display & Brightness screen, this happens. The brightness level you choose is the setting your iPhone will use in determining how to adjust the screen brightness for you as you move from one environment to a differently lit environment. If you happen to turn off Auto-Brightness, the brightness level you choose will remain constant irrespective of the environment.
How to Adjust the Sensitivity
Normally, Apple does not provide a way of adjusting the sensitivity of the iPhone’s touch screen. But if you find that the iPhone’s screen is sluggish or unresponsive, you can try using the following methods to have the issue fixed:
- Clean the screen, just like you would any glass surface. This is because it collects grease easily and this can interfere with the screen’s sensitivity.
- You can also restart and if necessary, reset the iPhone.
- Take your iPhone to an Apple Store for help.
