I updated my PS Vita to 1.80 and I know what it is suppose to have.  It allows you to play PS1 games, you can change the screen size while playing PS1 games, navigate the PS Vita without using touchscreen, few bugs fixed, and many more.  So I decided to test these out and I already have an issue.  I tried to use the dpad and/or the analog stick to try to choose which app I want to open and it does not work.  I do not know why, but I happen to restart my PS Vita and it still does not work.  Also, I play PS1 games on my PS Vita via Remote Play.  It works and I can change the button configuration.  But there was only one problem.  I wanted to change the screen size, but I did not see that option.  I looked it up on how to do it and they said that you can hold down the touchscreen for more than 2 seconds and it will display an Advanced Settings.  I tried that and nothing came up.  I do not know if I am the only one having this problem, but it is really annoying.  I want to know if there is something that I have to do to be able to have this to work.
