  1. the default dpi on my note 9 was set on 411… I did play with the dpi value quite abit and found the sweet spot for me 456 dpi… what I mean by sweet spot is changing the value to even 457 messed up my stock keyboard… but I now had more content on my screen even in my browser but the damn Samsung stock launcher was now messed up meaning the icons were too big for proportion with the reduced text size ( in stock settings the font size it set at the lowest size )( I like to read small , gives me tablet like feelings)…. I knew stock launcher was not the option to use in the long run with the modified dpi vale 456…so I paid for prime NOVA launcher and made a few modifications in the the nova settings changing the app drawer grid to 6 horizontal and 8 icons in vertical orientation … and OMG I love it soo much now… so my suggestion to anyone reading and trying to experiment is, go ahead and install the nova launcher with it is the best to go with it.. is my email id feel free to talk.. peace out enjoy ur beautiful note9
