guys, it's not that hard to do developer mode....
To enable "Developer Mode" on Vivo NEX S
Settings>More Settings>About Phone>Tap on "Software Version" 7 times then go to the previous screen. "Developer Options" is now added at the very bottom.
Notes
1. You do not need to turn on "Developer Options" switch to make adjustments to "minimum width" settings in the Drawing section.
2. This does not change the actual PPI of the screen (obviously), only sets DPI scaling, or the ability to adjust the size of on-screen content. Decreasing the value will give you larger icons and make text easier to read while increasing it will make on-screen elements smaller and fit more content on the screen.
ill have to cross post this in the other thread for clarification. apparently some are going through a lot of steps like downloading apps or having to connect to computer when it's as easy as tapping the screen a few times....
