When Windows Phone 8 discovers an NFC tag, it only tries to act upon the first record. If it does not recognize the record, or has no application to deal with it, it stops. There is no message to the user indicating what is going on even. The phone shakes and does its NFC tone, but then stops.

It would be great if the OS moved on to the second, third, etc, NFC record and tried to trigger off of them until there was a success. This is limiting the potential uses of NFC tags on Windows Phone 8 and making cross platform solutions very near impossible to implement into a smooth experience.

We are trying to develop a cross platform dynamic NFC tag for the public's consumption, called the DTAG100 (www.dtag100.com). We need for our applications on each of the mobile platforms to be able to read data on a separate NDEF records contained in an NDEF message. Windows Phone 8 is falling short in this regard, because it unnecessarily forces the first tag to be Windows Phone 8 specific.

If anyone at Microsoft is able to assist we would be happy to get our hardware into your hands. You could test NDEF message compositions not possible with standard static tags, and hopefully we could improve Windows Phone 8 NFC support.

I am unhappy with the way my Nokia Lumia notifies me for emails and messages.
Whatsapp is a widely used application and is very helpful for users without BBM. Now whatsapp doesn't run a background task in the windows phone 7.5 and thus i get notifications after hours of the time when the message was sent to me.
Also same is the scenario with Skype no background task for Skype and thus Skype has to stay opened if i want to stay online.
now coming to emails I get notification of emails received in the inbox but all the emails which are forwarded to a folder by a rule I have to regularly check those folder for email no notifications for those.
I will say the way application have to stay opened to keep them active is just awful when ever you hit back accidentally those applications are closed there is no way you can keep them in a background running and just notify you when something is new.
I wish windows phone could change that and keep it in the classic way the people loves it. The way multiple applications work hasn't changed in IOS, android and many other Mobile OS just because it is the best way multiple applications should work in the background.

Windows Phone 8 already handles some media type (MIME) NFC tags, but it could be improved upon substantially. We have developed a dynamic NFC tag that can broadcast NDEF Message up to 4 GB in size, and change the contents on demand. With this amount of space, we can share MP3 files, photographs, and other data that is typically too large to fit on an NFC tag. The problem is that Windows Phone 8 seems to have an artificial limit of 4 KB for how large of an NFC tag it can read. We would like to see this limit raised, or removed entirely, to allow for more creative NFC solutions to be produced.

We would be happy to provide test units of our DTAG100 dynamic NFC tag (www.dtag100.com) to Microsoft and the developers responsible for expanding the NFC stack of Windows Phone 8. We have begun to push the limits of what NFC can do with this hardware but we need mobile operating systems to push with us.

There is a problem with the scrolling behaviour of the maps control.

When scrolling around the map, as you take your finger off *during a scroll* (i.e. while the map is moving), the map suddenly accelerates/ jumps to much further past where you scrolled to, rather than stopping or gently slowing down (depending on animation level).

This problem is the most evident when the Animation property is set to "User-input", but it is also very noticable with the default Animation setting "Full".

This bug should be easy to fix, but currently it makes moving around the map very arkward and really ruins the usablity of the control.

Phone: Nokia Lumina 900/Windows 7.5
Car: 2012 Audi A4 w/MMI

Initially during setup everything paired perfectly with the car display seeing the phone (phone icon & signal bars) and the phone showing Bluetooth “on” and “Audi MMI 8023” connected.

After driving anywhere from 5 to 10 minutes in the car, the phone icon & signal bars on the car display disappears and the Bluetooth on the phone reads off. The Bluetooth on the phone only seems to shutoff randomly while the phone is in the car and not on my desk.

Is there any way to lock the Bluetooth setting on the phone?

Has anyone else experienced this problem and/or found a fix?

I understand others have experienced the same problem with the hands free configurations stating there seems to be a problem with the BT profile on the phone when it goes into 'sleep' mode.

Please advise.
