Having a button to toggle data on and off in the dropdown menu with Wi-Fi, sound, brightness, etc would be so convenient. It was on my last LG phone and I used it so many times a day. Now on my s6 I just end up leaving my data on because of how long it takes to get to the toggle setting, which cause me to run out of data really fast.
Their latest super expensive flagships doesn't have it, let alone S6. The problem is with carriers. They don't want Data Toggle on Samsung Phones, so Samsung removed it all together. Carriers don't push this request to other OEMs like LG or Huawei because Samsung is the dominant OEM and they capitalize on it. But there's a way to bring it back via Adb, search on XDA.
