Since the update on 4/6/16, my phone will automatically turn off the wifi connection, shortly after I turn it on, repeatedly. I have used half of my data in a day not realizing that the phone continually turns off the wifi, even though wifi stayed on until I turned it off prior to the update. I have it in a strong wifi with extender system in my office and it turns off after 30 sec. When I am using my phone, I have to watch the wifi icon constantly and tap it back on. At this rate it's a paperweight.
