My phone recently updated about a month ago and upon doing so I lost all my information as well and everything that stayed with the update was what I transferred over from my old phone. Why would it do that? question 2 is now my phone keeps telling me I have insufficient space all the time where as before I had so many apps and never had that come up but now I don't even have half the apps I had before. Please help me figure out how to get my phone to like it was before the update. I miss my favorite apps 
my phone constantly drops service now since the update
