does anyone recognise this app?(SS of an optimizer screen)

[Android Central Question]

my friends phone seems to be infected with some sort of optimiser that has completely taken over the phone so is obviously malware , it opens a fullscreen bright green or blue screen with an animation showing a round time/completion level meter and it alternates between saying it has optimised the memory, cleared the memory, cleaned the memory, cooled the battery etc etc etc , the bottom half of the screen has a built-in window for google adds, and after this timer has elapsed...a couple of seconds or so, it then shows another full page advert if you click it closed??
hopefully, I can attach a few screenshots,

Does it persist in Safe Mode?

It'd probably be best for your friend to start uninstalling apps one by one until that issue goes away.
