So I did the update.
After doing the update I messed something up and decided I wanted to just do a factory reset.
I did the factory reset and it reset to 5.0.01 Lollipop.
I had my contracts and pics backed up so I imported those.
I went to google play and downloaded all of my apps (free and paid ones) although after signing into google play I had to restart before I could download my previously paid apps as it wanted me to pay for them again.
Since I have done that and messed with some settings I have to say I am happy with the performance.
No lag issues, No battery issues as others have stated. Now when I was doing everything (downloading apps and checking settings) the battery did drain but that is to be expected since I was on it for hours doing things. After everything was done the battery has been as good...I would say it might even seem better.
Now I will have to go through the pain of changing all the apps notifications settings as the come in...If I am getting notification sounds I only want it for Texts, Phone Calls, Alarms and that would be about it...other notifications sounds from other apps just irritate me.
So...wondering how others are doing with the update so far. I have read that some had problems with their heart sensor being activated if anything is blocking it (like paper or something).
