The information you are looking for doesn't exist. At least not beyond the standard steps for that version of Android. If those steps do not work on your device, then the manufacturer has restricted this option in your devices copy of Android. Many do that. No fixing that. The only way to change it is to root the device. Which I am not an advocate of. Should you wish to consider rooting, then I suggest posting in that forum. http
