Tried using navigation today in walking mode. Searching and selecting a destination to navigate was absolutely fine. Clicked to navigate and the navigation screen showed "Vervolg uw route" at the top, zero speed, no eta or distance showing and navigation stopped. After about 2 minutes walking it came to life. Distance to turn froze a few times.
I'm guessing that my iPhone 4s is just not powerful enough for the app.
Anyone else testing using similar phone have this problem ?
Thanks Gert may be there is hope yet. Plan to update phone by the end of the year so no big issue for me.
