I don't know for sure what information you need to answer a few questions. My tablet (SMT-280) is running Android 5.1.1. Question1: Is it possible to set my Tab screen to ON "Always", that is, no display timeout? Question2: Is it possible to add, for example, a "two hour" ON setting for the display? Question3: If the answer to Q1 or Q2 is YES, then do you have any suggestions on how I might get started with the procedure to accomplish that?
