I really don't understand the mechanism of the app update notification, as I received my brand new Samsung ATIV S this February, I had to dig up the app updates one by one in Marketplace, literally, since it didn't pick them up automatically, then some 2 months later, I found that app updates poped up automatically between 7:30AM~8:30AM Taiwan time daily, I thought that MS might fixed the update problem, making it regularly. But some months later, the app updates began to pop up by 12:00PM~12:30PM, and now they appear to be showing up by 11:00AM.
I'm quite confused with this, since I don't enroll in any data plan from my carrier, all my internet connections on my phone are WiFi, I can only connect to free public WiFi hotspots when outside my home, which is very inconvenient. Compared with my previous Windows Phone HTC HD7, it seems to be no such problem, my HD7 would receive app updates when I turn it on, or connect to WiFi, no need to concern what time it is.
