So after breaking my regular phone I dug out the DHD as a backup. The old firmware was unusable really so I put this on about a week ago. It is really nice but I'm suffering from intermittent rather horrendous lag on it. It often takes so long to process an action that the screen timeout kicks in and the phone locks, other times apps get the wait/force close dialogue until they come back. Actions can be as simple as changing back to the home screen or swiping in the app menu.
I'm not entirely sure where to go with this as I did a full wipe before starting. Any suggestions before I give up and try an alternate?
