@users who experience portrait Waze while holding device landscape: my persistent landscape vs. portrait problems were fixed with a clean install and wipe of the sd-card folder, as I wrote in the previous beta topic. You might wanna give that a try too. Make sure to keep a backup of your history file somewhere else.
My thoughts on this beta do far: background stability problems SEEM TO BE FIXED! I wasn't able to make it crash by leaving it in the background for a while, making phone calls and using other apps. And, I really tried hard. However, this was just while sitting on my couch, no real life usage. That will come tomorrow morning.
The start menu still reverts to its small size:

Just repeating to keep things hot, please improve landscape behaviour:
- smaller navigation bar, to waste less display room
- Wazer popup bubbles not floating out of the screen all the time
- road event popup not overlapping the map where the event actually shows
No logs sent. Wait, did I really write that?
