I updated my Lumia 950 to the anniversary build (non-insider) and now gadgets doesn't work properly. If I tap my phone on the DT-910 it no longer opens the app I selected. Instead, it opens the gagdets app.
I've never used the NFC feature, what's it useful for in the context of charging?
I have found that the position of the phone (L950 in my case) on the plate is critical. If I have the bottom of the phone overhanging the charging plate by about 5mm, it charges fine. Much more than this, and it doesn't charge properly. So basically there is very much more hanging out from the top end, than there is at the bottom.
With the NFC tap, I had gadgets open the Night Stand Clock app to display the time, date and weather while charging.
I never use the NFC feature, but I have been having a lot of trouble charging my Lumia 950 with the DT-910. In the evening I would leave my phone on the charger, seemingly everything ok, only to find that in morning the phone did not charge at all and was at 60% even though it was at 100% before I went to sleep.
So I've now bought the wireless charging stand from CoJoie. It's advertised to only work with certain Samsung phones, but it works perfectly with my Lumia 950.
With regard to the NFC app you mentioned, is this much different from Glance? I have Glance enabled, it changes the text color to red at night and displays the date and time.
