I've been using 945 for few months now and out of sudden - the wallet stopped working. I entered the store, wanted to pay and the device could not detect my phone. What's more when I enter the wallet and get out of it, I need to enter the PIN EVERY SINGLE TIME - it's annoying.
I have 4.00 version on my phone and have successfully paid in the past.
If you only have to add something like - "it works in my case" please do not post at all, as it worked in my case as well but it stopped.
