The gyroscope sensor on your Android device is responsible for detecting the phone's orientation and movement. If this sensor is not working properly, it can cause your phone to act erratically or even become unusable. Fortunately, there are a few things you can do to try to fix the problem.
First, make sure that you have the latest software update for your device. Sometimes a simple software update can fix problems with sensors like the gyroscope.
If an update doesn't help, then the next step is to calibrate the gyroscope sensor. This can usually be done in the Settings menu of your phone. Look for a section labeled Sensors or something similar. Once you find the calibration option, follow the instructions on screen carefully. This will usually involve moving your phone around in different positions so that the sensor can get a good reading of its surroundings.
If neither of these solutions works, then you may need to take your phone to a repair shop or contact the manufacturer directly for assistance. In some cases, a defective gyroscope sensor cannot be fixed and will need to be replaced entirely.
