tried it without rooting file, still kills the tablet in sleep mode.
so , I think I am going to have to go back to the 2017 build, even without installing root, just the aosp-8.1-p4wifi-20181011.zip and open_gapps-arm-8.1-pico-20181222 .zip build , I noticed today when I think I had it in sleep mode , it would not power on by itself without first pluging in the usb to the computer port, in charging mode it was able to power on again, again I didn't have this bug or problem with the [ROM][Unofficial][AOSP] Android 7.1.2 Nougat build, that one worked without this problem, it doesn't die in sleep mode , or hard power off to the point, it wouldn't again power on without first getting the battery in charing mode, with the 8.1 build, I don't no why or whats causeing this problem with my Samsung galaxy 10.1 tab, model GT-P7510_XAB, again this tablet is only stable for me using the 7.1.2 build and older ones, this 8.1 build for some reason in sleep mode , hard powers off , and it will not turn the device back on with the button, unless its in charging mode, otherwise this old tablet acks like an paperweight without being able to turn it back on again etc.. only fix for this problem has been to put it into charging mode, in order to reboot it up again, otherwise without the uo) I had it once that the power button did not wake up the tab, it was like in a deep standby/freeze or something, had to reset the device, will provide a syslog next time.sb cable it acks died in sleep of death mode or sleep mode with this build, aosp-8.1-p4wifi-20181011.zip , the other thing is I did turn on the encrypting android feature, but that also worked before without problems under aosp 7.1, I going to have to downgrade the OS system on it again, until this bug is fixed. on this tablet model model GT-P7510_XAB, wifi only Samsung galaxy tab 10.1 p4wifi device.
