Try pressing the back of the note pro over the Samsung logo I have found that it works(did for me) it's a loose battery connector issue samsung cheap build, I know anyway if you have tried that and are frustrated of touching the Samsung logo again and again as the issue reappears then I suggest pull the back cover (use youtube) and unplug battery connector and plug it back again if you are unsure then just push battery connector downwards a little. I have tried all and first my note pro used to flicker at 46% battery level now hasn't flickered once till even 6% battery level moreover I can also say that battery life and performance has dramatically in proved as well!!!( By the way used geek bench and an tutu to compare) Hope it helps!! 'cause it sure did for me!!
