`detect_and_set_adb_keyboard()` concatenates stdout and stderr when reading the current IME. If the adb/hdc command fails (e.g. permission denied), the error message pollutes the IME string, causing `restore_keyboard()` to receive an invalid identifier and silently fail to restore the original keyboard. Use only stdout when the command succeeds; fall back to empty string on failure. Affects both ADB (phone_agent/adb/input.py) and HarmonyOS (phone_agent/hdc/input.py) code paths.

Problem
detect_and_set_adb_keyboard()concatenatesstdout + stderrwhen reading the current IME:If the command fails (e.g. permission denied, device disconnected), the error message from stderr pollutes the IME string. This corrupted string is later passed to
restore_keyboard(), which silently fails to restore the original keyboard — leaving the device stuck on ADB Keyboard.Fix
Only use
stdoutwhen the command succeeds (returncode == 0); fall back to empty string on failure.Affects both:
