After a bit more testing I found out: - when selecting a wifi connection the list refreshes and moves all the time: in a street in Paris with about 50 signals it's nearly impossible to select something down the list, refresh sends cursor back to beginning of list every second or so ("Searching" never goes away). - I'm not able to activate the virtual finger keyboard using my finger: internet search, web browser, application manager (forms), xterm input areas when thumb pressed seem to always show the virtual stylet keyboard. Only notes seems to detect properly a finger touch within its (larger) input area and opens the finger keyboard. - I've had three times after selecting "lock touch screen in keys" where after pressing power and seeing "now press HOME" the HOME button was inactive and I had to remove the battery or shutdown through remote ssh. This is with unmodified systemui.xml. I'll open bugzilla if I'm not alone in seeing this. Sincerely, Laurent
