The more apps you have on your system the more bloat where you have ! The more chances of an app causing a crash or instability etc One app i use always leaves a micro add on my screen ! The more apps you have the more chance one or two plus can run in the background and cause all sorts of issues . The more apps you have they communicate back to server etc One app i had caused an alarm chirp to occur got deleted ! Most i know who use this box keep it to a bery bear minimum ! [ there the ones who report less issues it seems ] If its not used delete it . And you have less chance of having any issues .
