Just spoke to someone and they are complaining about not having the phone manager app after the update to Emui9.1. The all that boosts your phone, scans for viruses and is able to block unwanted calls. If that is the case, I'd rather not update. Is that an option?

Thank you for your reply @Bobcatsysop YKChan
The Phone Manager was indeed renamed an now it is called Optimizer, it wasn't removed from the devices due to the new EMUI 9.1 update.
