Reason of existence of An App named "-5" I was trying to look at the battery usage of different apps and saw this weird app named &quot;-5&quot; on inspection it takes me to google photos which is weird since why will google photos use its name as &quot;-5&quot;. I can't find any reasoning for this and want others to shed some light on this topic. I have also reported this weird behavior to google as well.
I did a search in Play Store for &quot;-5&quot; with no results, also on YEE ole great god Google.  Not much returned.
I would start with your phone service provider.  They are suppose to give you a level of device support.  I've personally stumped the US Cellular chumps before.  Give it a try.  They do keep a knowledge base of customer calls. Who knows, you might be lucky.  Else download &quot;HouseCall&quot; from the Play Store, it is a TrendMicro manual scan for nasty things.  It is very powerful.  Free, only runs's when you run it.  TrendMicro has a variety of very good pay products for Android and web safe stuff.   Good luck.
