Why is My Samsung Tab A9 Half Sensor Not Working?
There can be several reasons why the half sensor on your Samsung Tab A9 isn’t working properly. Understanding these causes will help you identify the problem and find an effective solution.
1. Incorrect Audio Device Settings: One of the most common issues that affect sensors on devices is incorrect settings. If the sensor settings in your Samsung Tab A9 are misconfigured, the device may fail to recognize or respond to touch commands.
