Mobile data can be switched on and off from lock screen in android 5.0 lollipop. I casually leave my phone on desk for short time while I am nearby, somebody (suppose a kid) can toggle mobile data which can cause problems. For example it can incur a lot of charges if background data is enabled in my settings and somebody switches on the data. Or if I am downloading something in background then it can get interrupted if someone switches off data. Any solutions, tricks, etc. to solve this.
