Probably one of the biggest problems on this forum is newbies joining and jumping in at the deep end installing dangerous apps that clearly should have a better warning system attached and in doing so "brick" their devices so for me is to do nothing with your new device untill you have read up on all the problems that are happening simply because user don't understand enough and does not have the knowledge to play without having disastrous results resulting in "help me" posts.
So untill you have done your homework DON'T INSTALL NOTHING untill your sure of the consequences.
