I got hotspot problem. When i try to activate the hotspot with mobile data opened , it keep on turning on and off. However when i try to turn off mobile data and activate the hotspot , it worked. I tried to activate the hotspot and turn on mobile data after activated hotspot , the problem has appeared again, same as keep on turning on and off. There another situation that comes for the hotspot is after activated and try to edit the SSID or Password without mobile data , it appeared the same problem again. What should i do ? I have rooted and with stock rom and kernel. Android 4.4.2 D821
