+## 20900001 Input Device Operation Failed
+
+**Error Message**
+
+Failed to operate the input device.
+
+**Description**
+
+This error code is reported if the screen hopping status is abnormal when the screen hopping API is called.
+
+**Possible Cause**
+
+1. When screen hopping is initiated, the local device is in the hopped state.
+2. When screen hopping is disabled, the local device is in the free state.
+3. When screen hopping is disabled, the local device is in the hopping state.
+
+**Procedure**
+
+1. When initiating screen hopping, make sure that the local device is not in the hopped state.
+2. When disabling screen hopping, make sure that the local device is not in the free state.
+3. When disabling screen hopping, make sure that the local device is not in the hopping state.
