Mine just went!! It was just working a couple of mins ago. I tried holding down the buttons like you said for 5-10 secs and NOTHING!!! my phone is not even 4months old. This is not acceptable at all!! Please HELP ME!!!
Just had the same issue. With the screen off I held the power button and volume down button together for about 5 seconds. Side buttons working as intended and phone charging again. Thanks
My Galaxy's side buttons were working a few hours ago but all of a sudden they don't. And I haven't dropped it and there is no way to restart it and there are no reasons that this is happening besides a software bug. So could you please look into that?
