@CamilleBC
Your experience is a very good start, as my biggest question was about the touch screen
From my experience, to resolve the default viewing app and the shortcuts, I have decided to install Nova Launcher that is launched by default, with my own shortcuts at the botton (one opening the viewer installed by default).
I have also installed a fullscreen app, a screen rotation app and swapps (a menu on the left with my own shortcuts and the last opened apps).
Now my Lynx is perfect to me
If other people know the differences between the 2 firmwares, please share
Oh and a last question, CamilleBC : When Booxtor was installed, what happened when you kept the home button pushed, at the top left of the screen ?
Thanks for your help
