So the dreaded delay when waking up is still there, if you use the trackball to wake it, but the loudspeaker and slight delay on answer seems to be gone now. Why can't they fix that stupid wake-up via the trackball thing? It took me weeks to get used to using the space bar to wake it up, then I downgraded to 4.3 now back to 4.5...and having to use the space bar again...geez...seems they break more than they fix on upgrades.
