[Samsung Galaxy J5 (2015) ROMs, Kernels, Recoveries] one_half_3544:
Flashed this ROM to my j5nlte device (SM-J500FN). Indeed, felt sluggish - and then checked logcat and found out that NFC is constantly crashing:

NFC icon is disabled, so I guess there is no way to disable this process from the UI. How to disable it from adb?

Thanks.
