I have several issues with Samsung Galaxy s5 since the Lollipop update. I've read several other discussions about the battery drain (mine defintely is draining more quickly). the horrible "Interruptions" option in place of the "Blocking Mode" and maybe worst of all, the awful white notification panel that comes up in the middle of the night (I charge my phone during the night and use it as a daydeam clock). One thing that I have noticed but have not seen here is the fact that since I applied the update, my phone no longer shows as "LTE", rather it is showing "4G". We live in LTE area and had been showing as LTE prior to the update. Any ideas (other than reset to factory settings, not going there yet as it looks like it doesn't help).
