Good but there is a love hate in the case of Android with Google.
Google insists Android must be certified by Google, like the locked Apple platform, if you are to use Android Pay.
Google makes money from almost every app they pre installed.
Ads in YouTube, Chrome browser, in apps.
So I unlocked my bootloader, rooted vis magisk, use adaway to block ads. Iytpb for YouTube. On the Android devices I don't use Android Pay I use Xposed and minminguard.
There is a continuous battle between Google and rooting called safety net which if it senses not stock it prevents Android Pay.
I have an Android Wear which supports Android Pay, what I ended up doing is pair with an old phone which stays home so it runs stock. My phone in my pocket is rooted
What this means is I can leave house with just my watch, pair with Soundbud Slim+ and pay for things and receive calls and messages. Battery lasts about 4 hours on LTE.
