Since past few days I am unbale to switch WiFi off. It was alright but then suddenly one day, I just cannot turn it off. When it happened for the first time, I factory reset my device and then it was working fine. Yesterday I noticed the same issue again. From the notification bar or the settings, I am unable to swich it off. All this started after I installed the August update. Anybody else facing the same issue? Someone please let me know why is this happening?
