Over time, the touch screen on your Android device may falter. Before replacing your device, check if touch screen calibration can resolve issues. Follow these steps to recalibrate your Android smartphone or tablet.
Does your touchscreen require calibration?
With the advances and developments of Android, the hardware on which it is running has also evolved. Android hardware today is far better and more powerful than previous generations.
Modern Android touchscreens rarely require calibration or other configuration by the user. Touchscreen errors are more likely to be caused by hardware issues that can not be resolved than certain configuration issues.
However, calibration should not be completely ruled out, as it may be useful under certain circumstances.
For example, it may be a good way to adjust the sensitivity of your touch screen, especially if something else is acting on it. For example, certain types of screen protectors may affect the performance of your touch screen. This is a problem that can sometimes be resolved by calibration.
It is also recommended to try this on older devices where the technology is not advanced and the calibration can have bigger and more noticeable effects. Performing a touchscreen calibration will not hurt your age, but older devices may benefit more.
Testing the Screen
Before you begin, you need to check if the touch screen on your Android device is working properly.
Older versions of Android included secret menus and developer options that let you test and calibrate your touchscreen. This was important on older Android devices, as modern touchscreens were still in their infancy.
If you have an older Android phone, you can try accessing this secret touchscreen menu by typing * # * # 2664 # * # * . This option does not work on Android devices from Android 5 Lollipop.
Modern Android devices have apps available on the Google Play Store that you can use to test the touch screen instead. These will show you the reactions to your touch on the screen and help you judge if the screen is properly calibrated or not. A good option is the touchscreen test.
The use is simple. Install it and touch the screen wherever you want.
The app records white dots like a brush when you press your fingers. If the responses are delayed or otherwise out of sync, this indicates a screen problem that could be corrected by calibration first.
Calibrating Your Touchscreen
As mentioned previously, older versions of Android included in calibration tests. These tools let you test and calibrate your touch screen to see if it works properly.
This feature has been removed in recent versions of Android. For most modern Android devices, the only way to calibrate your touch screen is to use a calibration app from the Google Play Store.
A good app that you can try is the touch screen calibration with the appropriate name. First, install the app from the Google Play Store. Then open the app and tap the "Calibrate" button in the middle.
You can perform six touch tests after a single tap to pinch. Follow the instructions on the screen and perform each test. When the test is complete, a confirmation message appears.
Reboot your device and use an app like the touch screen test to see if this is the case Improvements.
If all else fails, perform a factory reset.
If the touchscreen still does not work properly after calibration, it can cause problems with Android that can only be resolved by a factory reset. Resetting to factory defaults is the nuclear option and does not guarantee that any problems with your touch screen will be resolved.
CONNECTION: Delete your Android device and restore it to its factory settings
Resetting your Android device will remove all existing apps and will clear any caches or settings that have been deleted may affect the touch screen configuration of your device. It can fix touchscreen delays that are a symptom of a bigger problem. For example, a device with severe delay issues may be caused by a lack of available resources that a reset might fix.
What is not done are hardware issues. If your touch screen is faulty, the problem can not be solved by a factory reset.
Performing a factory reset differs between handsets and manufacturers. However, you can find the option under Settings> System> Reset. Make sure you first make a backup of your device so your data will not be permanently lost.
