Why haven't you been able to use tap-to-pay?
First it was my Galaxy S3 on Verizon - apparently carrier restrictions got in the way as they were blocking it in favor of their own competing system - which took a long time to come about and only supported a couple card companies that I didn't use. Switched to T-Mobile when I got the Note3. The Note3 - I believe was also due to carrier restriction (not 100% sure on all this, so don't skewer me if I get some facts wrong here on out...) but part way through Google made some changes to the SD card and how it was used --- and from what I understood, this SHOULD have opened the door to all devices on current OS to be able to use Wallet tap to pay. Well, except the Note3... because Samsung apparently used some non standard NFC chip or controller that Android OS didn't have support for. That was all supposed to change with Lollipop... needed drivers would be included - or so it was rumored. Nope still no tap to pay
I shouldn't say I've NEVER been able to use it. Shortly after it was available, I used it at McDonalds a couple times with my 2012 Nexus7... got REALLY strange looks. For one, they hadn't seen ANYBODY EVER use tap to pay... second, I'm waving my tablet up at their terminal. Wasn't really practical with the Nexus7... but it worked - and I tried it everytime I had the tablet with me. That is until Google changed the way transactions are handled... and apparently the Nexus7 no longer had the 'right hardware' to do it anymore... leaving me again with no device tap to pay worked with.
Been burnt by it so many times from Carriers - to Google - to Samsung that I'm sick of it. Samsung Pay seems interesting... but curious if they'll roll it out for my Note3... and secondly for newer devices like the 4 or 5... will they somehow have a new way of blocking Google Wallet in favor of this? I haven't heard definitively... but at this point, I wouldn't be surprised in the least.
That's why I'm a bit bitter that my wife walks up with her iPhone -looks at me and smiles- and taps her phone to pay. I was doing this years ago (with a tablet mind you) yet I haven't been able to for several years now with supposed "Flagship devices." The whole system has been a mess, and of course Google has promised to revamp it with their Google Pay initiative. Though I can't help thinking its SO LATE and SLOW in coming and that I'm sure somebody is going to find some way to break it. Google's announcements seem nice until you realize that either your chosen device manufacturer or carrier has done something to remove/disable or simply not add the said feature. (Camera 2.0 api, multi-user, etc.) Or wondering if your < 2year old device will be graced with an update at all. Sure I could chose a Nexus device... but then be sacrificing some other key feature/ability/quality.

At least with NFC on Android it can be used for other things. I've got a tag on my keychain that toggles my hotspot (that was until that ability got broken in one of the Lollipop updates, I believe.) I had another that would toggle my phone to silent and back to previous state using Tasker... but the new volume scheme in Lollipop caused that to be unreliable to the point I haven't even reinstalled Tasker since my last device reset a few months ago.
I keep trying to find uses for NFC, but somebody always keeps taking them away. My Fitbit Flex allowed me to tap my device to it and it would launch the fitbit app on my phone. Unfortunately, Fitbit didn't put NFC in the newer tracker that I upgraded to. So now my primary NFC use is my Sony camera... I can simply tap my phone to the camera to transfer the current picture or to launch the remote camera control app. At least this is something that Apple's NFC can't do. But I don't know that many iOS users who would have kept trying 'fruitlessly' after being shot down over and over and over again for the past 4 years.
Sorry it went on so long... but you asked!!!
I won't spell out everything, but these are the types of things I've put up with on Android for over 6 years now. And honestly I was fine with that because of other customization, choice in screen size, ability to store media to sd card, easily swap battery, have a quality pen like Samsung's... and more.
But if, as people are claiming, several of these things are going to disappear - the platforms unique abilities - and the inherent benefits of being an Android user - keep getting diminished; these other factors make me question if I want to keep putting up with this... seems I'm eternally hopeful things will be fixed... yet the reply around here seems to be - suck it up; or buy something else that's inferior in some other way. Maybe I will... maybe I'll buy an iPhone <s> <kinda>.
It's not a big step for Apple to expand their NFC capabilities - though I'm not holding my breath. But someone else commented in another thread that what would be pure comedy is if Apple waited a year or so when almost nobody has SD any more - and they quietly added one to their SIM tray. How quickly would people be backtracking. I don't think they're that brilliant or gutsy... but it would be fun to watch.
