I have used a ton of betas in the past. We are on beta 2 if I'm not mistaken. The phone restarts on it's own mid app usage. The battery life is terrible. The signal is terrible. Usually a beta has real fictionally, this beta should have been uninstallable, effortlessly.
Once you leave the beta program it should download 3.2 again, but no why make it easy?
We do have a 3rd software update (ZUJG) available. Please update to the latest version and see if it helps resolve some of the issues. We also recommend clearing cache after the update.
