I recently switched to ZS171 and have noticed a few issues that I think are due to ZS, but am not sure.
- I have no Settings app anymore. It is not in my app drawer and pressing menu -> settings does nothing.
- Spare Parts force closes everytime I try to view anything about my battery
- Long-touching the home screen and clicking either Folders or Shortcuts opens my Browser
- There's no Power widget (possibly by design, not sure - found widgetsoid so not as big of a problem)
- If GPS is disabled and you use Navigation, a popup asking if you'd like to enable GPS comes up. Clicking OK should bring you into settings to correct the GPS setting, currently clicking OK on the popup has no effect (the popup just closes and GPS is still disabled, you never see the Settings menu)
