AT&T update on Galaxy Note 3

My camera is way different, I like my new speaker on my new keyboard it picks up my voice lots better than old one , lost all sorts of stuff like synced contacts, changes to notifications so I have to turn on my phone to see texts and it wont fix to the way it was before, I have a camera image on my lock screen that does absolutely nothing and when I swype to open screen the camera is randomly on uuuuugh I want my old phone back

That's what the camera icon on the lock screen is supposed to do. If you swipe it, it opens straight to the camera for easy access to take pictures. If you don't want to take a picture, just don't touch the camera when swiping. You can also go into your lock screen settings and modify what is on the lockscreen if you use swipe unlock.
 
Updated my phone a few days ago - now when I go through the email app that shows my 2 yahoo accounts, when I delete mail they are not deleting from the server. I never had this problem before update, now everytime I open my mail it shows lots of messages that I deleted, I have to go to website to delete emails now. I have looked everywhere for to try and find something that needs to be done to delete messages on server when deleted on phone and cannot find anything. I never had this problem before, am I missing something? I also check my gmail at the same time, did not want to have to install yahoo app and check my phone in multiple places to check email.
 
Has anyone noticed any battery loss?! I've noticed my battery is draining a lot quicker.

Sent From Samsung Note 3
Def noticed a difference between my stock and rooted Note 3. Both running the same version, only one is debloated and the other isnt. My rooted device has amazing battery life (dont even need to charge it over some nights), and the other needs charging by early/mid day. Interestingly enough, I dont really see anything specific in the battery logs that is causing the drain. Anyone find anything?
