I received the original build when 5.0 was released OTA for the Galaxy s5. When the "update" was pushed on 3/30, my phone developed an issue where the WiFi setting will turn itself on whenever it recognizes a WiFi. I have the "smart network switch" unchecked on my setting. This is a problem because Comcast has a hotspot network set up around Nashville so I'm CONSTANTLY having to turn off the WiFI. Just to reiterate, this behavior only started after the update on 3/30.
