A:AnswerI used "Smart Switch" simple process & worked great! Install the app...if it isn't already pre-installed on your devices (download from playstore) on both your phone & tablet then choose which device is to send / receive.
A:AnswerI have a TAB S2 as well as a Tab A. I suggest y ou see what apps are running all the time, like WI-FI or blurtooth and anything else in your drop down menu or other apps running in the background. I have had bluetooth run my battery when it had nothing to connect to. It keeps trolling for a connection and couldn't find one. I am not an expert by any stretch of the imaginatio os I hope this helps. Also leaving it on for long periods when you aren't using it could affect your battery life. Then, maybe your batteryy is just ready to give up.
