I have issues when run shell commands that require root privilege on Lenovo Tab 2 A8-50 (rooted)
1- I'm trying to hide the navigation bar on using adb shell command
I have to restart the device to get the effect but I get a black screen after restarting so I have to enable systemui to make the device run normally again "pm enable com.android.systemui".
2- Also shell command for screen capture get the "device launching image only" not the device screen "su -c /system/bin/screencap -p /sdcard/img.png"
The same commands run properly on different devices. Is there any kind of protection on this device that prevent shell commands run normally? What do I have to do?
