I've posted this before but I dont have this unit.
I've been told it works until you shut down, then it resets the time settings to auto, and screws it up again.
** So leave the unit on!!!
close all apps.
Go to Android settings/ Date & Time.
Turn off Automatic or Network Time adjustment and set to Manual.
Change your Timezone +/- according to the EPG Schedule time offset error.
Adjust the Time +/- so it reflects actual time where you are.
Back out of Settings and launch LiveTV program.
Guide "should" be correct.
*Like I said, don't shut the unit down"
Please Post your Results
Thanks
