Previously I reported issue with older waze version on my phone - see this thread - viewtopic.php?f=3&t=32801&start=240#p333766
I did a clean install after that and it worked perfectly - the only difference I made was instead of actively using it, I either left waze ran in background or ran it with 2D view and lower screen brightness. It never crashed since. I would just go in to activate navigation then either go back to my home screen or shut the screen off.
After the latest update, everything works as usual until today when I attempted to change from 2D view to 3D view - it crashed right away and rebooted my phone.
I don't know technical stuffs about this issue but I know that if I want waze to work for me, I have to do these steps:
1. Lower my screen brightness down (never max!)
2. Start waze
3. Change to 2D view
4. Set the course/navigation
5. Pray it won't crash
If you have same issue of your phone keeps rebooting, you may try my solution - see if it works for you too.
