Yes, it is possible to set your Samsung Galaxy A9+ tablet so that the screen never turns off when it is plugged in, even though the maximum time in the regular settings is 30 minutes. You can achieve this by enabling Developer Options and adjusting the settings there. Here’s how to do it:
-
Enable Developer Options:
- Go to Settings on your tablet.
- Scroll down and select About tablet.
- Find Build number and tap it 7 times. You should see a message that says “You are now a developer!”
-
Access Developer Options:
- Go back to Settings.
- Scroll down and you should now see Developer options listed. Tap on it.
-
Stay Awake Setting:
- In Developer options, look for the Stay awake option.
- Toggle the switch to enable it. This setting keeps the screen on while the device is charging.
By enabling the “Stay awake” option in Developer Options, your tablet screen will remain on indefinitely as long as it is plugged in and charging.
