Hi!
I have the 735 and I'm thinking about getting the preview for developers. Are there bugs or battery life problems or anything bad? Thanks! It would be great to get answers from 735 users with pfd.
There have been minor updates to the Preview for Developers which the official Windows Phone 8.1 Update + Lumia Denim release doesn't have.
Probably the main change is the addition of Cellular Data and Battery Saver action center quick toggles.
