I just installed the technical preview on my lumia 830, and I do realise how it is a early preview and so on. There's just one problem that's a bit too much: the keyboard doesn't work. I can properly use it only in Internet Explorer, nowhere else. In whatsapp for example I can only type one word and then it freezes. I have restarted the phone and reinstalled some apps. Didnt help. Do you have an easy fix for this? If not I'll just roll back right away, can't live without functioning keyboard. Too early build for me I guess
