5.1 bugs and missing feature?

Hi guys! So we do have android 5.1 on our z ultra, ram management improved,speed improved,battery life improved but i do notice that charging remaining time on the lockscreen isn't already there for 5.1 update.
And also the icon of the smart unlock trusted face feature is missing on the lock screen. Am i the only one who faces this bugs or you guys too after updated your z ultra to the latest 5.1.1 version.
