[Qualcomm SM6225][Android13][Kernel5.15]user version gets root permission by default
Description of requirements: The user version does not enable root privileges by default, but the general performance version needs to set CPU GPU DDR performance or monitor node information and other debugging methods to verify whether the current problem is related to CPU GPU DDR. Baseline code judgment logic: 1.adb code will detect related attributes […]
