I have an Asus TF303CL with KitKat. I'd like to use it as my alarm clock, but it seems that the alarm cannot sound if the tablet is turned off during the night.
On my previous android smartphone (a chinese phone with gingerbread) I could simply go to settings and set the time at which the phone would turn off and the time at which the phone would turn on in the morning, so my phone was completely turned off during the night (it was not in airplane mode, it was turned off), turned on 5 minutes before the alarm and the alarm could sound.
How can I achieve the same effect with this tablet? I've already checked the settings but I cannot find any entry similar to what I had on the old phone.
I know it's possible, since I've been able to do that for 2 years with a basic chinese smartphone; surely this brand new tablet can do everything that old phone could do. Maybe rooting the device is required for such a functionality?
