Totally understand and agree to the pain! It's a real pathetic implementation of that proximity sensor in the phone application!

Can anyone please help us disabling that stupid proximity sensor while actually on a phone call. Generally/personally, my phone calls don't last more than a few minutes (at max). So, even if the screen is continuously ON during that time, I won't have an issue. But to wait for the screen to appear back when I move the phone away from the ear is an extremely painful thing.

"Phone" app is the WORST app ever written on N900. Same holds true for the "Application Manager" too.

Those guys/teams should be fired immediately without notice actually!

There is also this issue with the placement of multi-app-menu-icon (left-hand top corner). The time I finish the call and when I see the phone screen, some random apps would have been opened!

I hope the MeeGo DE would take into considerations these usability issues seriously.
