CCleaner does not appear under Accessibility->Services where I should be able to grant access for a Deep Clean. Is there another place this can be granted? Or how do I get CCleaner on the list of Services displayed? Thanks for your help
On my LG, it is Settings> General> Accessibility> at the bottom, find Services, and listed there is CCleaner. Select, and turn ON if you would like CCleaner to "deep clean".
After I did it, I got a black screen for longer than I expected. My phone restarted & I took away permission. Not sure if I'd recommend the deep clean without more information about what it is really doing.
Good luck!
