Hi Folks. I'm 78 year old new guy on the block.Can anyone advise me please ? Have a Galaxy 7.7 6800 G3 Wi Fi Tab.running ICS. When attempting to download Apps I very often have a yellow panel appear, stating, "YOU HAVE NO DEVICES and refuses to download. Is there a setting that I need to adjust or is this normal for this model running ICS please ? Regards, Rod.
