Hello Everyone 
I am using tinker s with Android 7 Nougat V14.2.2.73 
I need to back up clock time in case of power failure
I have DS3231 chip
Is it possible ?
It's possible, but I'm not familiar with Android. First off you need to have admin privileges over the installation. Then you should check whether there's /dev/rtc0.
