There was a Verizon software update a few days ago that I ran on my Samsung Galaxy 6, and it's made my phone next to useless. Everything is now slow and sludgy -- Messaging, Facebook, other apps, internet access. I clean junk and boost storage virtually daily and I'm not anywhere close to capacity on RAM usage, so that can't be the problem. This definitely started right after the update. Can I go back to the old version, or is there a fix for this?
