Can I add this function? (Change auto brightness level)

I found that there has a function to change auto brightness level on Korean Galaxy note 3 model.
But my ATT Galaxy note doesn't have that function.

Can i add it?

Auto VNC on startup

I have a Lenovo Yoga Tab 3 tablet running Android 5.1.1

How can I setup a VNC viewer that starts automatically on startup and also re-connects automatically when connection is disrupted? In Windows, I am able to achieve this with Bitvise Tunnelier. I do intend to VNC over SSH tunnel.

Any pointers are much appreciated, thanks!

HTC can't disable auto rotate, even when off in settings

Suddenly out of nowhere (only thing I've done is reinstall elementalx kernel with same settings) my phone autorotates everywhere, even lock and home screens, all 3 direction even.

Any ideas how I can figure out what's wrong?

Auto Brightness Bug - Update

Just wondering if anyone has heard if Samsung plans on ever fixing the auto brightness bug that so many of the edge phones are experiencing. I have seen the methods for fixing it by replacing the services file in framework, but do not want to root my phone as of now (not even sure if there is a root out for a SM-G928V yet). Anyone heard anything new? Got a software updated just this morning (10/21/2015) and it did not fix the problem. For anyone who doesn't know, the issue is that even though auto brightness is turned off, the phone screen dims whenever in unlit areas and brightens once light is present. Any information is appreciated. Thanks.
