i just noticed on my Note9 (my 1st unlocked device), when running device maintenance the highest i get is 90. my T-mobile branded S8+ and S9+ will report 100. all 3 devices are set up the same. I see there is a "Device Security-deactivated option on the Note 9 that's not on the Tmobile devices. It prompts me to turn on/activate McAffee. is that the only way to get 100?? just curious. doe anyone use that "anti-malware"??
