AWFUL, AWFUL, AWFUL!!! I want my old operating system back. I have a Samsung S5 with Verizon. NOTHING WORKS... my phone is unusable! It freezes, powers itself off randomly, battery drains extremely fast, apps won't open, "errors" out because it can't open something... this has been a nightmare and I've been battling it for 5 days. I've been into Verizon store twice! Lo and behold, once you've "upgraded" to Lollipop, you're stuck with it and can't even put it back to factory specs. Seriously?.... Someone should have made sure that it worked before letting this thing loose on customers. My advice...DON'T upgrade until they've fixed the bugs, and it better be soon!!!!!
