I have about 6 android smartphones. All use wifi only for internet access.
Only the Samsung G3 causes stomach\abdomin\gut pains.
I also have about 6 tablets. Only the Toshiba encore 2 gives me the same stomach pains as the G3 does.
I found the pains are caused by the wifi transmit power output level.
After reducing the Toshiba encore 2 tablet wifi power from 100% to 25% I've not had any more stomach pain.
Unfortunately I haven't found any way to reduce the G3 wifi transmitt power output. It is my only device that gives me stomach pains.
