My first week with Q-10 (Sprint) today. Trying to resolve "overnight low-dead battery issue" with replacement battery (ordered by Sprint) at the moment. New battery was dead and is recharging right now (not a good sign). Got my email to work by using the Sprint support page for the Q-10 by entering my email address and following the setup procedure for the server settings (after spending hours searching the web without finding an intelligent solution)...kudos for Sprint. Got the BIS email to forward to my new email using Blackberry KB33260, the first part didn't make sense to me, so I skipped directly to just entering my BIS email address and forwarding to my new email. The KB article is confusing and doesn't list the Sprint BIS carrier, so I entered "sprint" in the body of the URL address and went ahead and it worked...demerit for BlackBerry.
Yes , the new UI is really poor for productivity, the touch screen sensitivity is all over the map with different functions and is not left hand friendly if you keep your device on your left hip.
The Video player won't play certain formats that worked in the old OS, so now I have to convert those files.
I would really prefer a souped-up Bold with the old OS and new 4G radio over this PITA...that said, I hope OS11 is improved and can retro-install like the iPhone.
Unless you need a QWERTY keyboard, a smartphone that fits and carries well in hand and on hip, are anti-Google (Android), want to manage your device on your PC - not in someone's Cloud, and are tech-oriented, STAY AWAY FROM BLACKBERRY.
