Recently I detected an annoying UI bug since updating waze to V3.1.1.
When clicking the menu icon at the bottom left corner, and then clicking on My Waze, instead of bringing me to the My Waze main menu, it takes me directly to the My Mood list instead. Then when clicking the back button at the top left while viewing the My Mood list, instead of going back to the My Waze menu, it skips it and goes directly to the main "Menu" selection screen. Summarized, the My Waze menu is being skipped all together when proceeding forward and back between the first and last steps.
This only occurs upon start-up of the application, or when returning to the application after viewing other applications while it is running in the background. After going through the above steps described above once, the menu screens load in the correct sequence without any issue.
Visual Description:
First clicked on My Waze.

My Waze menu skipped, instead displays My Mood.

Upon clicking back button in above picture, My Waze menu skipped yet again, and main Menu displayed.

Upon clicking My Waze again, My Waze menu finally displayed.

It is nothing that really hurts the application at all, just is annoying to me lol.
There is another bug I have noticed as well, and it is even more annoying but I have no clue how to really visually report it or retrace steps that lead up to it for it is randomly occurring.
When driving around, my iPhone's backlight kicks on and off, on and off, basically flickering depending on how the phone moves, this includes when I am making a turn or a tight curve. If the phone remains in one position (again it is not a set position and completely random), the screen will go black, and then when I shake the phone or stand it up right or lay it down depending on its previous position, the screen will light up again. I know their is a feature called keep-backlight on, and I have left it at its default "On" position for I do not want it turning off no matter what for battery conservation is not a concern to me for I have a car charger. Re-installing the application does not fix this bug at all, and it occurs multiple times each day I am driving, and closing the application and rebooting it only temporarily solves the problem.
