I have been so happy with my Galaxy Note 4 and the OS until the latest October updates. The first was the major update that had some interesting features including WI-FI calling which I could care less about. And with this update, using the Samsung messaging app, I can no longer attach text to MMS messages for pictures. Awesome. I have to turn LTE off. Really?! But, the most frustrating thing is the multiple crashes/reboots per day. Needless to say I'm pissed with the latest major update. It's updates like this that make me want to switch to the dreaded iPhone.
